All cores were taken using aluminum inner core barrels. Five Core Laboratories field personnel assisted with wellsite sampling and core handling. Sampling and disposition of the core was conducted according to Arco's instructions. A summary of these procedures can be found in the appendix. CORE LAB PERSONNEL FUNCTIONS 1. Set up and preparation of core trailer, supplies, and equipment. 2. Caught and prepared core for movement from rig floor to core trailer. 3. Fitted together core, marked depths, selected samples, and worked in the preservation process. 4. Cut and trimmed wellsite plugs and samples, and assisted with the preservation when needed. 5. Operated rock saw to cut full diameter core samples for wellsite plugging. CORE HANDLING AND PRESERVATION BY CORE LAB PERSONNEL Core Lab representatives were present on the rig floor when the core barrel was disconnected. They ensured that the core was kept in proper order and covered to minimize exposure to the atmosphere during transport to the core trailer. Cores 1 through 6, which were contained in aluminum inner core barrels, were taken to the pipe shed, depth marked and double striped, and cut into three foot sections with tubing cutters. The ends of the sections were then rubber capped and clamped. These sections were then taken to the core trailer. Upon arrival of the core at the core trailer a Core Lab representative, assisted by an ARCO person, ensured that the core was properly fitted together, and oriented with the apparent up dip at the top, and marked. Two types of sample intervals were marked on the core at the wellsite. Each had a three letter designation which was marked on the core and later on the foil wrapping. A three inch section near the foot mark was marked SCF, and a plug sample site was marked on the end nearest the foot mark. No sample site was allowed within one inch of a fracture in the core. Where possible an adjacent two inch piece was marked in every third foot and labeled SCL. Once the samples were designated and marked the SCF section was dry cut by a second Core Lab person. A one inch slab was removed. The two slabs were wrapped together with a saran layer separating the slabs. A spacer replaced the sample section. The designated SCF plug sections were then taken to a second core trailer for plugging. The remaining core and SCF pieces returned after plugging were then preserved in saran wrap and foil, marked, and dipped in Core Seal. The core was then placed in boxes for shipment to Anchorage. Core Lab and ARCO personnel were present in the second core trailer for wellsite plugging, preservation of the plugs and wrapping of the SCF samples. The 1.5 inch plugs were drilled with Hexadecane, and dry trimmed. Care was taken to ensure that sample exposure was minimized. All trimmed wellsite plugs and plug ends were preserved in six layers of Saran wrap and three layers of aluminum foil, and sealed in glass jars. The plugged SCF sample was wrapped in saran wrap and foil, marked and taken to the first core trailer for dipping in Core Seal. After preservation the plugged SCF piece was inserted into the appropriate box with the rest of the core. The boxes were marked, taped, and stacked for shipment to Core Laboratories~ Anchorage facility. Please refer to the appendix for a more complete description of the wel 1 s i te procedures. Conventional Core Processing in Anchorage Upon arrival at Core Laboratories' Anchorage facility, the preserved core pieces were removed from their boxes, placed in depth order, and surface core gamma logged one core at a time. After core gamma logging, the SCL samples selected at the wellsite were depreserved and 1.5 inch horizontal plugs were drilled in the same manner as the SCF plugs taken at the well site. These plugs and ends were immediately preserved for minimum exposure and placed in jars. The remaining whole core was rewrapped. The sampling completed, the core was depreserved 10 feet at a time, and slabbed 1/4 and 3/4. The 3/4 slabbed sections were immediately represerved with Saran Wrap, foil, and Core Seal. The 1/4 sections were washed with fresh water and allowed to dry for viewing and photography. The SCF samples were received from the wellsite in cool ice chests. These samples were kept cool and in their sealed jars until loaded into the Dean-Stark apparatus. A more complete description of the core processing procedures can be found in the appendix. Core Photographs The core was oriented with the top of the bedding at the top of the core and slabbed 1/4-3/4. Approximately 15 feet of the cleaned 1/4 slabbed sections appears in each photograph. Five sets of visible spectrum flash and five sets of ultraviolet light photographs appear in separate binders. Conventional Analysls Techniques Core analysis methods as specified by Arco were applied to the SCF, SCL, and selected plug ends at Core Laboratories' Anchorage facility. The procedures are detailed in the appendix. Several changes to the procedures were instituted during the process, as noted below. GLASS BOTTLES, page 8 Original · Bottles referred to for core plug and end piece sample storage are described as having metal lids. Change- All bottles had plastic lids with teflon liners. In limited tests these lids performed better than metal lids. CUTTING AND TRIMMING CORE PLUGS, page 11-13 Original' Calls for placing sample numbers on plug and end pieces. Change: Given the oil mud and chosen solvents, placing marks on the plugs and end pieces would be impractical and/or potentially damaging to the analysis. Foil was labeled for plugs waiting to be loaded into the Dean Stark units. Once unwrapped, the sample thimbles were marked and separate labels were placed with the samples from station-to-station until the samples were dry. At that point, numbering was applied to the sample. Original- Refers to the chloroform-methanol cleaning equipment as Dean Stark glassware. Change: While a few Dean Stark glassware units were used for this step, most samples were cleaned in Dean Stark units made, predominantly, of metal. These systems were approved by ARCO. To assess solvent color, an aliquot was removed and observed in a 250 ml glass beaker. If dirty, the solvent in the boiling chamber was replaced. This was done almost daily, until clean solvent was observed. Original-Calls for retaining each sample in its bag during the drying/weight stabilization step. Change: There was interest in minimizing weight changes attributed to loss of fines through the bag. The process was changed so that after the first 24 hour drying period in the vacuum oven, the sample plus bag and thimble were weighed. Weighing continued at 24 hour intervals until a weight change of no more than .02 grams was observed. Fines on the sample (from plugging and trimming) were brushed off with at toothbrush and the sample reweighed and returned to the vacuum oven for another drying period. POROSITY, GRAIN VOLUME, page 16 Original' Calls for a "known volume" instrument check using a steel cylinder ever 2 hours during grain volume analysis. Change: Frequency of this check was on the basis of every day and whenever there was a break in usage greater than one hour and after ever 5 samples. PERMEABILITY TO AIR, page 16-17 Original: Does not call for a plug weight after drying overnight following sonication of plug ends in 2% KCL. Change: A weight was recorded. Dean-Stark Fluid Saturation Measurements Water was extracted from the samples by Dean-Stark technique using toluene in cleaned apparatuses. Fresh commercial grade toluene was used for each extraction and the equipment was cleaned between each sample as directed by Arco. Extraction continued until no change in water volume was observed over a four hour period. Minimum extraction time was twelve hours. All spent toluene was recovered for chemical analysis. Samples were removed from the water Dean-Starks and placed in cleaning Dean Stark units until the 87 volume% chloroform - 13 vol% methanol cleaning solution showed no crude oil color after eight hours. Extracted samples were dried in a 180 degrees F vacuum oven for a minimum of 24 hours and until sample weights were constant to .01 grams over a four hour drying period. Samples were cooled in a desiccator to room temperature before porosity and permeability was measured. Saturations by Dean-Stark methods were calculated using Equations 1 and 2. Where' So : [((W1 - W2 - H20)/Do)/Vpc] x 100 Sw = [H20/Vpc] x 100 (2) So = Oil Saturations, Percent Sw = Water Saturation, Percent W1 : Natural Weight W2 : Extracted and Dried Weight H20 : Extracted Water, Density Assumed 1.0 gm/cc Do = Density of Oil, .85 gm/cc Vpc : Pore Volume, Corrected for Grain Loss (see below) Corrections for grain loss were applied to the water and oil saturation calculations. The corrections were made using equation 2a and 2b. Vpc = Vp x [(W2 + Wgl)/W2] (2a) Where' Vpc = Corrected Pore Volume Vp = Measured Pore Volume of Dried, Clean Sample W2 -- Extracted and Dried Weight of the Sample Wgl = Weight of the Grains Lost During the Process Where: Wgl = Wpb- Wb - W2 (2b) Wgl = Weight of Grains Lost During the Process Wpb = Dry, Stable Weight of the Plug plus the Arco Prescribed Bag W2 = Extracted and Dried Weight of the Sample Grain Density Grain volume determinations were measured on all samples according to Boyle~s Law utilizing the Extended Range Helium Porosimeter. The equipment was calibrated to yield a grain density variation of less than .005 gm/cc. Grain densities were calculated using Equation 3. Dg : Mg/Vg (3) Where- Dg = Grain Density Vg = Grain Volume Mg = Grain Mass Atmospheric Porosit.¥ The horizontal plug samples were measured for bulk volume by mercury or displacement at ambient conditions. Porosity was calculated using Equation 4. P = [(Vb-Vg) / VD)] x 100 (4) Where: P = Porosity, Percent Vb : Bulk Volume Vg : Grain Volume Al~mospheric Permeability to, Air Horizontal permeabilities were measured in a Hassler type core holder at a confining pressure, of 400 psig after the plugs were cleaned in a sonic cleaner and redried. Permeability calculations were performed as defined by Darcy's Equation for compressible fluids, Equation 5. No permeabilities were measured on the PG ends or Tracer samples. Pa x v x 1000 Qa x L x L K = x (5) (P1 - P2)(P1 +P2) Vb Where- K = Permeability v = Gas Viscosity P1 - P2 -- Differential Pressure P1 + P2 2 Mean Pressure Pa = Atmospheric Pressure Qa = Flow Rate L -- Length Vb: Bulk Volume Mud Filtrate In Core Tracer concentration in plug samples was calculated using tracer concentrations supplied by CPM Laboratories. Tracer percent was calculated using Equation 6. Sof : 100*(Wo*Ff/O.85)/Vp (6) Where' Sof = Saturation of Filtrate in Core (% pore volume) Wo -- Weight of Oil Phase in the Core Ff : Weight Fraction of Filtrate in the Oil in the Core Vp = Pore Volume of the Core (cc's) Explanation of Core Saturations Anomalies In some instances the computation of oil and/or water saturation has resulted in water saturations over 100% and oil saturations less than 0%. Some possible explanations are listed below. Water saturations computed greater than 100% can be caused by the following: - high water reading - low bulk volume - high grain volume Oil saturations computed less than 0% can be caused by the following: - low sample fresh weight - low bulk volume - high grain volume - high water reading - mass loss from thimble or bag. All input parameters and calculations have been checked. Where appropriate, samples have be retested for grain and bulk volumes. The most probable explanation for both of these anomalies is high water readings, due to de- watering of clay minerals. The samples had a very high clay content, and at Dean Stark temperatures (toluene boiling point 235-240 deg. F.) the clays release some bound water. This explanation is speculative, and further testing would be required to confirm this. These spurious values are given in the data report and are marked with the symbol "*", with a footnote referring to this discussion.

CORING OB_IECFIVES The coring involves mineral oil base cores in 4-13 wells. These cores will provide in-situ water saturation, rock properties and lithology for the use of the Point Mclntyre Working Interest Owners. GENERAL GUIDELINES 1. This procedure is for well site sampling and laboratory core analysis. . Core Laboratories must be able to mark, lay-out, cut core barrels and preserve on-site. They must be able to plug on-site. Laboratory sampling and routine core analysis will be conducted in Anchorage. Tracer will be conducted elsewhere. . Early cored wells might require plugging on-site while other wells may not require plugging on- site. Earlier wells are more likely to have extensive well site sampling. . 5. All wells will involve the following: A. Core preservation (Saran wrap and aluminum foil on-site). B. Core Diameter - 4-inches C. Inner Barrels - Aluminum, 30-foot, 60-foot D. Low invasion core bits and coring procedures E. Expedited core processing Timing will be between March 1, 1992 to March 1, 1993. Estimated well site timing and estimated volume could vary significantly depending on rig schedules and data requirement needs. The first well may begin coring April 21, 1992. Other wells will follow in one-month intervals until a second rig becomes available later in 1992. Two well coring operations might occur at the same time dependant on rig schedule.

Well site personnel requirements per job will vary from 8-24. Personnel number requirements will vary depending on whether plugging is conducted on-site. Core Labs will provide 2-16 people per well depending on well site activities. 7. Laboratory staffing and equipment must be adequate to meet core analysis timing requirements. 1 . 10. August 3,1992 Materials that Core Labs must be able to supply on coring jobs are listed below. Quantities will vary depending on amount of projected coring for each individual well. The procedures outlined in this contract proposal may vary significantly from well to well. ARCO will provide details of revisions prior to conducting the work. Iodonapthalene drilling mud tracer will be used in all wells to quantify filtrate invasion. WELL SITE CORE HANDLING AND SA/~IPLING Recommended Tools and Materials Quantifies will vary depending on amount of projected individual well cored interval.

Material and Site Preparation Upon arrival at the well site, the required preservation materials .will be set up in the core trailer by Core Lab personnel. The melting pot will be filled with Core Seal and turned on..' The pot temperature will be adjusted according to the length of time before the core is recovered, place on low (180 °F) if more than 48 hours is anticipated. It is recommended that the melting pot be checked at regular intervals when turned on and never exceed the recommended dipping temperature for Core Seal (320 o. 330 °F). The dip pot temperature must be monitored and recorded for each core preserved. All personnel will be H2S certified and will need to familiarize themselves with the areas on the well site that they will be working in while retrieving the core such as the rig floor, pipe shed, and core trailer location. Contractor will provide safety equipment for their own personnel. This includes, but will not be limited to, steel toed boots, safety glasses, hard hats, dust masks, etc. Also, all personnel should be aware of their areas of responsibility in the preservation operation. Two coring trailers will be required for wells with on-site plugging. ARCO will provide trailers. Trailer I will be used for core layout, depth marking, sampling and preservation of whole core. Trailer 2 will be used for core plugging and represervation of plug and endpiece. Routine core plugs cut at the well site will be preserved in Trailer 2. One trailer will be required if all plugging is done in Anchorage. The trailer Will be used for core layout, depth marking, sampling and preserving of whole core. Upon completion of the above preparations, the core boxes should be put together and marked with client name, well name, core number, and box number. August 3, 1992 Samples of Coring Mud for Tracer Analysis At the start and end of each core, the mud man will collect a mud sample from the suction pit. This sample will be 1 gallon, collected in a metal DOT approved container with screw cap and fiber lid seal. The label on the can will include well name, core number, core depth and date. This mud sample will be shipped with the core when it is sent to Anchorage. Inner Barrel Laydown, Cutting, Capping and Transportation The aluminum inner barrel will be laid down in 30-foot lengths on the skate and transported to the catwalk. Use a sling and hoist to carry the inner barrel to the inner barrel cutting cradle and cut it up. Wipe down the outer surface of the inner barrel to remove mud. Locate the top of the core and mark inner barrel. Double stripe red and black, red on right looking up-hole. Mark depths each foot on outer barrel starting from core top. Using pipe cutters, cut the inner barrel into 3-foot lengths. Place rubber caps on each end'of core. Secure caps with hose clamps tightened by an air driven nut driver. Load inner barrel sections on fork lift and transport to core trailer for layout. Core Lay-Out in Trailer 1 The core should be laid out on the counter in 5- or 10-foot lengths by a Service Company Lab representative. Core barrel is layed on bench with red marking nearest the core trailer wall. Dump core out of inner barrel sections onto lay-out bench. Uphole is always to the left. Core pieces are wiped with dry rags to remove mud, fitted together, oriented with the apparent up dip at the top, depth marked and double striped for orientation. Depths shall be marked below the corresponding foot line and orientation lines marked with white on the right and yellow on the left using waterproof markers. It is recommended that lumber crayons be used for marking core surface and Marks-A-Lot markers (red and black, red on right) for foil wrapped core.. While the core is laid out, murine analysis samples (3" X 4") are marked every foot starting at the foot marker and extending three inches below the marker. If this location is not suitable for plugging, 'the sample top may be moved down by 2.4 inches below the foot marker or the sample top may be moved 2.4 ~-"~:~~inches::above..~t~?.~foot mark~~~amples are identified with the initials SCF (Service Company, Field Sample) and must be dry sawed to separate them from the core. At 90° clockwise from the white and yellow double stripe while looking up hole, mark the plug location with a circle as close to the foot marker as possible. The SCF whole core samples are preserved separately from the remaining core for ready identification once they reach Anchorage. Slabbing on-site will be done only 'when plugs are taken on-site. While core is marked, core inventory and descriptions can be performed providing the exposure of the core is kept to a minimum. State chips will be taken in Anchorage. Quality Control Wells Qv~rvi~w of Approach Well site core sampling is planned for quality control purposes. This type of sampling might be more intense in the early wells and may decrease in later wells if it is shown that sampling in Anchorage provides similar water saturation and tracer distribution to that obtainable in the field. It is also possible that all wells may be sampled at the wellsite. This decision will be made after two wells are Below for the . o o o . IA. August 3,1992 are the procedures which are planned for the quality control wells. These procedures will apply first two wells: Conduct coring in the usual manner in order to achieve low invasion. Core bits appropriate to the rock type will be selected for coring. Mud tracer, iodonapthelene, will be used to indicate the level of invasion by the mud filtrate. The core handling for these cores will be the similar to all other cores as specified under Core Handling Procedures detailed below. When the core is laid out and marked at the well site, dry saw a 3-inch full diameter section of core every foot for routine analysis. Mark it with the initials SCF. Immediately preserve all core, including the dry sawed sections, in Saran wrap and aluminum foil as described later in imore detail. Mark the location of the SCL (Service Company, Laboratory Samples) section (2-inch full diameter; once every third foot) on the foil for ready identification in Anchorage. This two-inch section will be cut in Anchorage. Proceed with normal core preservation for all samples except the dry sawed 3-inch sections. Routine horizontal core plugs will be cut at the well site from the $CF samples in each foot. These core plugs will be 1.5-inch diameter cut parallel to bedding planes completely through the core after a 1-inch slab has been removed from the face where the plugging bit enters. This will prevent driving tracer into the core center if the core plugging fluid invades the core. The routine plug will be trimmed and preserved as discussed below. Double stripe the 1-inch slab for orientation. The remnant core/slab will then be represerved in Saran wrap and foil. Additional routine core sampling later in Anchorage can provide quality control on core preservation and tracer diffusion. Once in Anchorage, identify SCL sections as marked at the well site every third foot. Routine core plugs are cut from these sections immediately after the core arrives. Cut the two-inch section. These core plugs will be 1.5-inch diameter and cut parallel .to bedding planes completely through the core after a 1-inch slab has been removed from the. face where the plugging bit enters. Double stripe the l-inch slab for orientation. The remnant core/slab will then be wrapped together in Saran wrap. The routine plug will be trimmed and preserved as discussed below. This sample will be analyzed for water saturation and tracer content for comparison to the well site samples. The first priority in data collection is to obtain porosity and water saturation in those intervals sampled both in the field and laboratory. Adjacent SCF and SCL plugs will be analyzed immediately. The endpieces of both field and laboratory samples will be analyzed, for tracer every six feet-of core in both field and laboratory samples. More tracer data can be obtained later as needed. If there is no well site sampling, then the above section entitled Quality Control Wells can be ignored. A three-inch SC section will be identified for each foot, dry sawed from the core and preserved at the well site. This sample will be marked clearly SC, with the depth and with double stripe orientationd At 90° degrees clockwise from the white and yellow double stripe while looking up hole, mark the plug location with a circle. If the section is unsuitable for plugging, the SC sample top may be moved down 2.4 inches below the foot marker or 2.4 inches above the foot marker. If the plugs are cut in Anchorage, then the SC sample will be slabbed in Anchorage prior to plugging. The section would be replaced in sequence with the rest of the core, preserved and shipped to Anchorage for plugging. It is also possible ali routine core plugs may be cut at the well site in all wells. This will be decided after the first two wells are cored. If plugging is continued on site, no plugs will be cut in Anchorage. August 3, 1992 Core Handling Procedures Core lay-out will proceed as described under Core Lay-out in Trailer 1 procedures. SCF samples are identified and the core is marked. SCF samples will be taken every foot. Whole core sections for SCF samples are dry cut on the rock saw to separate them from the core. The sawing operation requires a dust mask. A 1-inch slab is then cut at 90° clockwise looking up hole to the double mark. The double stripe is always on the most updip side of the core. This slabbed face will be the side where plugging starts. The circle indicating the plug location should always be on the one- inch slab. ROUTINE CORE SAMPLE 11 SLABBED FAC Please note: If plugs are not cut at the well site, then the SC samples will not be slabbed at the well site. This face is immediately covered with Saran wrap and the 1-inch slab is placed on top so the Saran separates slab and butt portions. The 1-inch slab should be double striped for orientation. This section is then replaced in the core at the appropriate depth. The samples removed are replaced with wood block spacers containing the appropriate depth and sample marking. These samples are then wrapped in their normal depth sequence in heavy duty impermeable Saran (6 layers) and heavy duty aluminum foil (3 layers). SCF samples from everY foot are taken to Trailer 2 for on-site plugging. Place a wooden block to hold the sample space until it returns from Trailer 2. Depth orientation lines are to appear on both the core itself and foil wrapping. A routine core plug will be cut at the well site from each foot of core; therefore, two core plugging devices are needed. A 1.5-inch horizontal core plug will be cut parallel to bedding completely through the whole core section at its center starting at the saw-cut face from which the slab was taken. Care should be taken to ensure the core drill is perpendicular to the slab face. Use hexadecane driven by nitrogen from a lO-gallon, 300 psi container. The SCF or SCL plug will always be cut as close to the foot marker as possible. If the sample is below the foot marker, plug at the top of the sample. If the plug is above the foot marker, plug at the bottom of the sample. Dab core plug, if necesary, with an Oiisorbent tissue to remove excess oil immediately after plugging. Use a fresh tissue for each plug to avoid tracer August 3, 1992 contamination. Trim one end of the core plug with a dry saw so the final plug is 1.5 inches long. If the plugging bit was not perpendicular to the slab face, first trim the slab side of the plug 1/8 inch (the width of the saw blade) and then trim off the endpiece so that the resulting plug is 1.5 inches long. The diagram below shows the trimmed plug. SC SAMPLE 1.25" I END · PIECE iCORE PLUG ~i~ , - The plug is passed on for preservation immediately in Saran wrap (6 layers), aluminum foil (3 layers), weighed and sealed in a labeled glass bottle with a teflon-lined plastic lid and sealing tape. Bottle label should specify well, core number, depth, and preserved plug weight. These plugs will be kept cold in a .refrigerator or on ice until analyzed in Anchorage. These plugs will be used for routine saturation measurement. The plug endpiece will be preserved .immediately and separately from the plug. as it is generated. The endpiece must be marked with depth on the rock, identified as an endpiece (SCFEP) and wrapped with Saran wrap (6 layers) and aluminum foil (3 layers) and weighed (± 0.01 g). The endpiece from each' plug is then placed in a glass bottle, sealed and taped. The endpieces will be kept cold in a refrigerator or on ice until analyzed for tracer content as specified in Table 2 in Anchorage. Bottle label should specify well, core number, SCFEP depth, tare and total weight. The routine core sample 3/4 remnant could be used to obtain a vertical core plug later on. This sample and the slab will be Saran and aluminum foil wrapped as one piece, depth marked and identified SCF in Trailer 2. The 1-inch slab should be double striped for Orientation. The sample and the slab are then returned to Trailer 1 for Core Seal coating and placed in depth sequence with the rest of the core. Remove the wooden block when the sample is replaced in depth sequence. If geological samples are needed and the plug endpiece is still preserved, the slab may be used to obtain geological sampleS .for thin sections, etc. The plug itself will not. be used for geological sampling since it must be saved for possible future remeasurement of permeability or porosity as a part of quality control procedures. Core Preservation The core is placed with the top to the left on the bench in Trailer 1. This will help insure that the proper core orientation is maintained. When moved across to the other bench for wrapping this orientation is maintained. The wrapping stations must be covered with Oilsorbent tissue to provide a soft surface which will not damage Saran and foil. Wrapping should begin as soon as possible following SC sample identification and separation. The core August 3, 1992 is then wrapped with Saran wrap (6 layers), then wrapped with aluminum foil (3 layers) and marked. Wrapped core will be marked with depth using a black Marks-A-Lot and with red and black (red on right) orientation lines. Glass strapping tape is placed on the foil under the wire to prevent puncture of the foil. Wire is wrapped tightly around the center of the core to facilitate the dipping of the samples in Core Seal. The core should be completely submerged in the dip tank for 1-2 seconds and then hung on the cooling rack. After the Core Seal has cooled (3-5 minutes), the sample should be redipped to insure a proper seal and to help protect the core from damage during shipment. After the second dip, the wire is cut at a point just above the preserved piece and a small amount of Core Seal should be placed over the exposed wire to eliminate a wicking'effect. As the core is preserved, the core is then placed in oil absorbent tissue or bubble wrap lined core boxes. Then, the core is checked for proper preservation and markings. Occasionally the Core Seal will be too thick to read the markings. Therefore, if possible, a waterproof marker should be used to mark the appropriate designations on the outside of the sample. The core is placed in the core boxes and the boxes are labeled on the outside with well name, equity well name core number and box number. Then, the boxes are sealed. A well site inventory shall be completed for each core and the boxes are placed in shipping crates. Core and Mud Sample Transportation to Anchorage Tracer analysis data will be most valid immediately after coring as an indicator of invasion and degrades with time due to diffusion. The transportation of the cores and associated mud samples will be expedited. Immediately upon completing the boxing of the preserved core, the core, mud samples, routine core plugs and endpieces will be transported by airplane to Anchorage. Ice chests and blue ice will be used to transport routine core plugs and endpieces to Anchorage. Place the jars in holes cut in styrofoam to prevent breakage in the ice chests. The service company personnel will meet the flight and pick up the core. Core processing will begin immediately upon arrival at the laboratory. ROLFYINE CORE ANALYSIS; There will be a designated representative of the Operating Company who will act as the point of contact for all matters relating to routine core analysis. All communications with the Service Company will be through that point of contact. The point of contact will also be notified if other Working Interest Owners wish to observe ongoing analysis operations. The operating company will provide a list of personnel who have access to the slabbed core. General Core Handling Core sampling will be conducted with minimum elapsed time since the core was cut and preserved. Tracer diffusion stops once routine plugs are isolated from the more invaded outer part of the core. Sample the core immediately upon arrival at the service laboratory regardless of the time of day. The service company personnel will be notified when-the core leaves Prudhoe Bay and will pick-up the core shipment at the airport once the freight company releases it. The service company can expect to receive up to two 60-foot cores in a single 24-hour period. In straighter holes and good sandstone pay, it may be possible to cut as many as three cores a day. The primary objective is to Obtain true connate water saturations with consistent analytical techniques. Laboratory procedures and core handling should always be done consistently. Exposure to air should be minimized to avoid evaporation of fluids and wettability changes. August 3~ 1992 . A tracer will be used to identify those routine core plugs that have significant mud filtrate invasion. The tracer chemical is iodonaphthalene which is analyzed chromatographically with an electron capture detector. It will be found in the flask with the toluene and extracted crude after Dean Stark analysis. LVT-200, the base oil of the mud, can be used as a back-up tracer. Care should be taken to ensure that there is no inadvertent contamination with other chlorinated hydrocarbons, such as chloroform, which will be used in core cleaning. The analysis procedure used to detect the tracer is extremely sensitive with detection limits of 50 ppb. Large concentrations of chloroform may obscure the tracer which is expected to be present in the Dean Stark toluene at less than 1 ppm. Chlorinated solvents must never be used to clean glassware or core drill equipment. Glassware used for chloroform-methanol cleaning must never be used for the Dean Stark. Each new container of toluene must be sampled and analyzed prior to its use. , The quality control cores are needed to ensure water saturation and tracer distribution are the same in the laboratory as they were at the well site. Well site routine core plugs will be taken once per foot in at least the first two wells. In these wells, a routine horizontal plug and an endpiece will also be cut once every three feet later in the Anchorage lab. These contiguous samples will be analyzed for tracer concentration, porosity and water saturation. Some endpieces will also be analyzed for water saturation and tracer to provide inside and outside sample data. Tables ! and 2 identify sample types, sample and data frequency. . Ail plug drilling will be done with hexadecane. The containers of hexadecane must be sampled at the time they are opened for use. These samples will be sent to the outside laboratory with the toluene before use to analyze for materials which may give a response on the electron capture detector. A record will be kept by Core Laboratories concerning the well core and plug numbers cut with a given container of hexadecane. o Sawing will be done with a dry saw for small samples such as plugs or when cutting out full diameter core sections. Slabbing can be conducted with cooled nitrogen gas to cool the saw blade. Slabbing will only be done after sampling for saturation measurement is finished so the small amount of contamination from condensed moisture which may occur here should not be a problem for any additional tests. o All core will be 1/4 slabbed at a later time. The core will be kept in a preserved state until it is slabbed. Any samples which are depreserved for the purpose of sampling and analysis will be represerved as quickly as possible to prevent loss of fluids from the remnant. After slabbing, the 3/4 butt end will be immediately represerved with minimum exposure. The 1/4 slab will become a library sample and should be double striped and placed in a slab box. . Chips will be taken for the State of Alaska at the time of core plugging, if not already taken at the well site. 10. Calibrations will be performed on all balances using standard weights at least once before every core. Weights used should approximate sample weights. Flow Chart of Laboratory Operations A flow chart of laboratory operations is attached. Mud Filtrate Samples There will be two drilling mud samples shipped from the field with each of the cores. One of these will be taken at the start of coring and one will be taken at the end of coring. A sample of the filtrate is needed so that the tracer concentration can be analyzed. This tracer concentration in the filtrate is August 3, 1992 essential to the calculation of filtrate concentration in the cores. Therefore, it must be collected and sent with the toluene samples from a given core in order to obtain the filtrate concentration. M.I. Drilling Fluids is providing a high pressure, high temperature filter press to filter these mud samples. Core Laboratories will filter the samples. The filter press should be cleaned with naphtha and dried at 300 °F between samples. Conduct the filtration at 500 psi and 150 °F until 2 cc of filtrate are collected. This will take about 1 hour. Collect filtrate in a 5-10 cc glass container; seal and tape when finished. Identify core number, core depth, well name, and date on the label. Surface Core Gamma Log The core is laid out on tables in depth order. The core remains preserved while it is gamma logged. The core gamma unit is calibrated with a 2001API gamma ray emitter before every core. The core is placed on a conveyor belt (beginning with the bottom of the core) which moves the core at a constant speed under the gamma detector. The pieces are butted tight to one another, with no breaks in measurements, until the core is completely logged. Now-the recorded gamma ray response is digitized and plotted. Cutting and Trimming Core Plugs Core plugs will be cut with hexadecane. New containers of the oils should be analyzed chromatographically before use so that inadvertent interference with tracer analysis does not occur. If LVT-200 is needed as a tracer, the hexadecane will not interfere with its analysis. To ensure there is no contamination with tracer from previous plugging operations, the oil will be driven with regulated nitrogen from a 10-gallon container. The hexadecane will be used only once. Cut the 1.5-inch diameter horizontal routine plugs parallel to bedding plane. Look for yellow and white double stripe on top of the core, rotate core 90° clockwise while looking up hole and dry saw a l- inch slab from the whole core. Double s~pe the 1-inch slab. The plug will be cut from the butt portion starting at this saw-cut face. The diagram below illustrates the slab and plug locations. ROUTINE CORE SAMPLE 4~ SLABBED FAC 10 Note: This diagram will apply to any plug cut in Anchorage or at the well site. However, the SCL samples are two inches in length instead of three inches. If core plugs are not cut at the well site, the three inch section, cut with a dry saw at the well site, will be used in the laboratory for plugging. A circle will indicate the direction for the cutting the core plug. The plug will always be cut as close as possible to the foot marker as possible. If plugs are not cut at the well site, then slabbing before plugging will be done in Anchorage. The plug should be cut completely thrOugh the center of the core and as close to the depth mark as possible. Take care to be sure the plugging bit is perpendicular to the slab face, otherwise the plug may need to be trimmed. Dab core plug, if necesary, with an OilSorbent tissue to remove excess oil immediately after plugging. Use fresh tissue for each plug tO aVoid tracer contamination from other plugs. Trim one end of the core plug with a dry. saw so'that the final plug is 1.5 inches long. If the plugging bit was not perpendicular to the slab face, first trim the slab side of the plug 1/8 inch(the width of the saw blade) and then trim off the endpiece so that the .resulting plug is 1.5-inches long. Identify well and plug number on the core plug.and endpiece. Preserve plug and endpiece separately in Saran wrap (6 layers) and aluminum foil (3 layers). Take preserved weight of the plug or end piece. Relabel with plug/EP number on the foil. Place wrapped plug and endpiece in separate bottles, seal and tape. Label the bottles with well name, depth, plug number and total weight. Indicate endpiece with EP following plug number. Store the plug and endpiece at 50 °F in refrigerator. The figure below shows the plug and trimmed end. SC SAMPLE 1.25" ' 1.5. ':: Routine Horizontal Core Plugs Oualitv Control Well If the core is from a quality control well, a routine horizontal core plug and endpiece 1.5 inches in diameter are cut, one per three feet, in the lab immediately below the field sample location in that foot. The SCL section should have been identified and marked at the well site. Depreserve the appropriate whole core sample and cut the 2-inch whole core section with a dry saw. A l-inch slab is 11 August 3, 1992 cut 90° clockwise looking up hole to the double mark. The 1-inch slab is double striped for orientation. All routine horizontal plugs and end pieces must be cut as rapidly as possible and plugging should be completed within 24 hours after the core reaches the surface at the well site. Weigh the plug or end piece, and preservation materials. Preserve the whole core sample in Saran wrap and aluminum foil before it is moved to core plugging. Place Saran wrap between slab and butt portion; then, wrap them together. The cutting of the Anchorage core plug and endpiece in a quality control well will be exactly as described above except that a 2-inch long core segment is used rather than a 3-inch long whole core segment. The core plug is cut through the center of the 2-inch core segment. No vertical core plugs will ever be needed from these samples. Routine core plugs will also be cut at the well site in qUality control wells. These will be transported from Prudhoe Bay in ice chests with blUe ice to maintain low temperature and prevent loss of water from the plug. Routine core plugs cut at the well site will be taken immediately to the Dean Stark station for analysis. If a Dean Stark apparatus is not available, the plugs should'be maintained at 50 °F until analysis can be performed. Both wellsite and Anchorage lab routine core plug endpieces will be analyzed once every 6 feet in quality control wells. Endpiece analysis will always be done on immediately adjacent samples from the wellsite and the Anchorage lab. The analysis procedure for the endpiece will be the same as for routine core plugs except air permeability will not be determined. Ail Other Cores .....

Depreserve these samples one at a time and cut a 1.5-inch diameter routine horizontal plug as close to the upper end of the sample as possible. The technique for plugging, trimming and preserving this plug and endpiece has been described above. Routine core plugs will be analyzed one per foot. Core plug endpieces will be analyzed one per 6 feet. Ail routine horizontal plugs and endpieces must be cut as rapidly as'possible and plugging should be completed within 24 hours after the core reaches the surface at the well site. Mark depth, orientation, and represerve the 3/4 whole core remnant in Saran wrap (6 layers), aluminum foil (3 layers) and Core Seal (two coats). The 3/4 remnant could possibly be used for cutting a vertical plug later on. Replace 'the preserved sample and the slab in depth sequence in the core. When plugs are cut in Anchorage, there will be no need to preserve the l-inch slab taken prior to plugging. This was done in the field to avoid lost identification and ibreakage of the slab during shipping. Later,' this routine sample slab can be placed in depth sequence with the rest of the slab, when slabbing of the Dean Stark Analysis Weigh the preserved core plug or endpiece after removing form the bottle and record this weight on' the data sheet. This weight will be compared to the well site weight or the earlier Anchorage weight. Filtrate saturation in the core plug as indicated by a tracer will be used for quality control of water saturation. Anchorage plugs should be preserved in saran and aluminum foil, and weighed immediately after cutting. The plug should then be refrigerated until Dean-Stark analysis. Prior to loading, plugs should be reweighed to ensure preservation was adequate. 12 August 3, 1992 The Dean Stark method is used to determine water saturation. The tracer in the core will be removed in the Dean Stark extraction and will be found in the flask with the toluene, filtrate, hexadecane plugging oil and crude oil. Fresh commercial grade toluene must be used for each plug analyzed. New containers of toluene must be sampled and analyzed before use. The flasks and glassware must be cleaned from the previous use to insure there is no residual water or tracer. Rinse condenser, core chamber and flask five times with 20cc of fresh toluene and discard the rinses. Weigh a clean, dry Dean Stark flask. Measure 100cc (_+ 1 cc) of preboiled toluene and add to a preweighed flask. Toluene must be preboiled external to the glassware and within two days before use. To keep toluene loss to a minimum, keep the system closed except when adding or removing sample. The same person should always assemble the glassware. The core plug is removed from its preservation materials. The core plug is weighed to an accuracy of _+0.00! g, placed in a predried and prelabeled cloth core bag to trap lost grains and reweighed to the same precision. If core plugs are soft-or poorly consolidated in some intervals, then encase them in Teflon tape, aluminum or lead foil and screens prior to the last weight. Obtain individual weights on Teflon, foil, and screens. The plug is then loaded into the Dean Stark apparatus without further delay. Then, seal the apparatus. Perform all tasks for one plug at a time. Toluene is refluxed until no further change in the water volume in the receiver is observed for four hours. Minimum extraction time is twelve hours. Use a wire or a wire with a teflon swab to scrape off water droplets from the neck of the condenser so they fall into the receiver. Do not use soap. Record the volume of the water to within _+0.025cc (1.2% PV @ 10% porosity). If water volume is less than 0.5 cc, pull water from receiver with a syringe and weigh it. Remove plug from bag. Place the plug on top of the bag in a pre-dried, pre-labeled and pre-weighed thimble. Remove the flask and its contents from the Dean Stark. Remove toluene in the side arm with a syringe and add it to the flask. Weigh the flask + toluene mixture. Using a funnel that has been rinsed five times in toluene, pour flask contents into a D.O.T. approved shipping bottle. Be sure the cap is tightly closed so it will not loosen in shipping. In addition, seal the bottle with tape. Label bottle with well, core number, core depth and plug number (with SCF or SCL, and EP designation, if endpiece). These samples will then be shipped in one core lots (approximately 60 feet) to ARCO Exploration and Production Technology in Piano, Texas. The address can be found in the appendix. The packaging will be according to DOT regulations. The plug, bag and thimble should then be placed in a second piece of Dean Stark glassware for 87 vol% chloroform-13 vol% methanol azeotrope extraction. The chloroform will interfere with tracer analysis, if it should be present in the toluene extract in high concentration. Glassware used for azeotrope extraction should never be interchanged with glassware used for the Dean Stark. Change azeotrope after the first forty-eight hours; then, change it every twenty-four hours. Continue azeotrope extraction until clean azeotrope shows no crude oil color after eight hours. Streaming fluorescence with methylene chloride will be checked to monitor cleaning progress. Extraction time should be a minimum of two days. i Dry core plug, bag and thimble in a convection oven at 180 F for 4 hours. Then, dry the core plug, bag and thimble in a vacuum oven for at least 24 hours at 180 °F and then to constant weight, _+0.01 grams, after four hours additional drying.: Cool the plug, bag and thimble over desiccant. Weigh the plug, bag and thimble within _+0.001 g. Remove plug from thimble. Brush plug to remove fines and weigh again. Timing Glassware requirements should be based on two 60-foot cores per day with a 12-hour Dean Stark cycle and a 48- to 96-hour cleaning cycle. This means we need at least 80 sets of Dean Stark equipment for water measurement. The additional 20 sets will be required for the quality control cores. With these 80 13 August 3, 1992 sets of water determination equipment, 80 plugs could be generated for cleaning per day. Since the probable cycle time for cleaning is 2 to 4 days, we need 320 sets of equipment for chloroform-methanol extraction. The timing for cleaning is hardest to predict, since iow permeability plugs will undoubtedly require more time. 400 separate pieces of Dean Stark glassware are required. This will permit a completion time for Dean Stark and cleaning of approximately 7 to 9 days for a 4 core well. The tracer analysis lab will finish up in about 9 days, or 1 to 3 days later, allowing 1 day shipping time to receive the first batch of samples. The tracer analysis time might be cut to 5 days with two chromatographs. Porosities should be complete about two days after the last samples are clean. Data processing time for saturations and tracer data is estimated as three days. The four core, well cycle time for water saturation, porosity, and tracer should be 14 days. Air permeability will probably lag water saturation, porosity and tracer data by about 5 days. In normal operations (one well drilled, cased and cored), all data on a given well could be complete before coring operations begin on the next well, assuming 20 days to drill and case, 5 days to core, 2 days to log, 1 day to skid the rig. For wells that require more than 4 cores, the time for completion of analyses will then be extended proportionately. For wells with fewer cores, there will be more flexibility on timing but these should be complete in the same time frame. Table 2 also indicates timing for data turnaround. Additional equipment will be required when two rigs are coring. Core. Laboratories will provide an estimate of man power and equipment requirements for two rigs. Porosity Porosity is calculated from the difference in bulk volume and grain volume divided by the bulk volume. The pore volume is the difference between bulk volume and grain volume. That is the value used to calculate saturations. Grain Volume The helium porosimeter will be used toldetermine the grain volume of all samples.. Plugs from drying are kept over desiccant until ready fOr grain volume measurement. If the plugs are exposed to laboratory air for more than 30 minutes, they should be redried and reweighed. The helium porosimeter should be recalibrated to _+0.1% twice a day. The porosimeter should be checked with a steel cylinder with a known volume to _+0.1% after every five samples and after a break in instrument usage of greater than one hour. If drift between successive calibrations will cause grain density to vary _+0.005 g/cc, calibrate before every plug. Bulk Volume Bulk volume for all 1.5-inch diameter plugs will be measured using the mercury porosimeter. Bulk volume will be measured within _+0.01 cc (_+0.05% BV). Maximum depth of immersion in mercury will be the minimum required to yield an accurate bulk volume. The plug must be weighed within +0.001 g before and after the mercury immersion.to check for mercury intrusion. Any weight gain greater than 0.04 g (0.0030 cc out of 42 cc approximate bulk volume) will be significant intrusion. Bulk volume will be increased to correct for the calculated me/'cury intrusion. Correction for Grain Loss Grain loss is being measured and corrections for this will be made. The ratio of weight to pore volume is assumed to be constant for the grains lost: The correction will be made using the following equation' Ws + Wg;l Vp Vpc - Ws Wgl = Wd - Wthi - Wbi - Ws 14 August 3, 1992 where Vp Vpc Wbi Wd Wgl Ws Wthi Pore Volume in cubic centimeters Pore Volume corrected for grain loss in cubic centimeters Initial weight of bag in grams Dryweight of sample, bag and thimble in grams Weight of grain loss during analysis in grams Weight of sample used in pore volume calculation in grams Initial weight of thimble in grams This corrected pore volume will be used to calculate both oil and water saturations. Permeability to Air Permeability to air is measured on all roUtine horizontal core plugs (not measured for endpieces). The fine materials generated while Sawing should be cleaned from the plug faces before this measurement is made. Use 2% sodium chloride brine and a sonic cleaner. Clean each end of the core plug and then dry the plug overnight in a vacuum oven at 180 °F. Samples will be weighed to stability following the same procedures specified after cleaning. Then proceed with measurement of permeability. Permeability is measured with 400 psi net overburden pressure. Complete recalibration of permeameter will be performed every two wells. Check plugs of known permeability will be used to check calibration daily. Permeability should be measured with a stable air flow rate. Routine horizontal core plugs will be used in this measurement only after the completion of bulk volume. Tracer Analysis .: All on-site routine core plugs and off-site routine core plugs will be analyzed for tracer. Routine core plug endpieces will be analyzed for tracer once every 6 feet for both on'Site and. off-site samples. ,The tracer analysis will be conducted On roUtine core plugs and endpieces to provide an indication of filtrate' invasion. The drilling mud filtrates generated above will also be analyzed to determine filtrate saturation. Iodonaphthalene will be the tracer. An alternate tracer (LVT-200) would be used in the event of a problem with analysis for iodonaphthalene. Gas chromatography with an electron capture detector (ECD) will be used to detect the iodonaphthalene. The flame ionization detector (FID) will be used to detect LVT-200 and plugging oil. A splitter before the detector will be used in the analysis so that the ECD and FID analyses are generated simultaneously. An injection port splitter is being used to separate the toluene so that rotary evaporation is not required to analyze for plugging oil and LVT-200. The plugging oil analysis will be quantitative. The LVT-200 analysis will be only qualitative but can be made quantitative if needed. The LVT-200 will be readily apparent on the chromatogram any time its concentration in the oil exceeds about 5%. The procedures for quantitative analysis of iodonaphthalene and plugging oil are in Appendix I. Chromatographic analyses will be performed by an outside lab. Tightly capped and taped containers of the toluene will be transfered to that location from ARCO's Piano lab cold storage. The addreSs for shipping and analysis is in the appendix. The outside lab will conduct analYseS for tracer in the toluene mixture and in the drilling mud filtrates. The outside lab will provide for each sample a sample description, weight of sample upon receipt, tracer concentration (ppm) from analysis, dilution factor, total tracer concentration (ppm), and weight percent plugging fluid. The data will be provided by the outside lab to Core LaboratorieS in the form of an IBM PC floppy disk. The appendix contains a calculation procedure for filtrate saturation, plugging fluid saturation and corrected oil saturation in the routine core and endpieces at the surface. 15 August 3, 1992 Core Slabbing Core slabbing may be conducted when the schedule permits and when the Operating Company representative decides. The core will be depreserved 10 feet at a time. The core pieces will be fit together so that the same side of the core is always presented in the slab. The core will be slabbed 1/4- 3/4 so that the bedding and dip angle are clearly observable. The 3/4 slab should retain the white and yellow stripe and depth markings made at the well site. Rotate the core 90° clockwise looking up hole from these markings and cut the slab. The white and yellow markings are on the updip side of the core. Plugs cut from 3/4 section on the slab side will be parallel to bedding. Slabbing should be conducted using cooled nitrogen to cool the Saw blade. Double stripe the 1-inch slab for orientation. The 3/4 butt end of the core will be immediately represerved in order to minimize exposure. The preservation procedure used will be identical to the initial preservation in the field: six layers of Saran wrap, three layers of aluminium foil, and two dips of Core Seal. The routine core analysis sample was slabbed at the time of plugging. This slab should be placed in a slab box in styrofoam inserts to prevent breakage and in depth sequence with the rest of the slab. The routine core analysis 3/4 section should remain preserved. This section could be used to obtain a vertical core plug adjacent to the horizontal plug for permeability measurement. Preservation of the core will make it easier to extract the crude oil since the sample will not be dried out. The slab will be placed in slab boxes with styrofoam inserts after slabbing. Future Uses of the Preserved Core The 3/4 butt end of the core which has been preserved will provide a future source of core for formation damage, vertical permeability, chloride measurements, relative permeability, etc. It is not known at .this time how much of these data can b.el justified for reservoir engineering pUrposes, so data acquisition will be delayed until the needs are better defined. A 3/4 slab is called for above since it will allow a 2- to 2.5-inch long plug to be obtained parallel to bedding. A 2/3 slab will only allow a 1.5- to 2-inch long plug which may not be adequate for some lab tests. 16 Table 1 Sample Identification August 3, 1992 SCF SCL SCFEP SCLEP Field routine horizontal core plug, 1 l/2"x 1 1/2" Laboratory routine horizontal plug 1 1/2" x I 1/2" End piece:of field routine horizontal plug, I 1/2" x 1" End piece of laboratory-routine horizontal plug, 1 1/2." x 1" 17 Sample SCF SCL SCFEP SCLEP Sample Location Field Lab Field Lab Table 2 Sampling and Analysis Frequency *** Sample Data Data Freq Type Freq Turnaround 1/FT o,S,T 1/FT 2 Weeks 1/3FT* o,S,T 1/3FT 2 Weeks 1/FI' o,S,T 1/6FT 2 Weeks 1/3FT* o,S,T 1/6FT** 2 Weeks August 3, 1992 In later wells field samples may not be taken and lab sample frequency will increase to one per foot.

To accomplish this, a halogenated tracer (1-iodonaphthalene) is added to the drilling fluid at a concentration of =30 ppm and a "pure" component (hexadecane) is used as a cutting fluid. Each core sample is extracted with approximately 125 mi of reagent grade toluene. The sUbsequent'core extracts are analyzed by gas chromatography (GC) utilizing an electron capture detector (ECD) and a Flame Ionization Dector (FID). The degree of core invasion by the drilling mud is based on the concentration of tracer contained in the toluene extract and the pore Volume of the extracted core plug. In a similar fashion, the cutting fluid (hexadecane) invasion is based on the concentration of the hexadecane in the toluene extract.

A 0,Sml aliqUOtof each sample:isdilUted 1:1 by volume with the internal standard solution (i:e:;'2' ppm Iododecaneand 1.0 % Squalane inToluene). (2b) In the case of the concentrated drilling fluid solutions it will be necessary to predilute them ~0.4 g of sample to 10.00 gm with reagent toluene. Actual weights are recorded to the nearest milligram along with the respective dilution factor. (3) 5.0 Itl of the sample/internal standard blend is injected into the GC splitter via the auto sampler and data acquisition is initialized. (4) After the' internal standard: and tracer'have eluted the three-port 'valve is actuated and the oven temperature allowed to proceed to.its maximum setting. . (5) From the ECD, the concentrati'on-of the tracer is determined using the 1 ppm iododecane peak as an internal standard along with the response factor relating area counts to concentration. The internal standard is used to correct for variations in sample size reaching the detector.' (6) FroTM the FID, the Concentrat'ion of the-cUtting flUid is determined using the 0.5% Squalane peak as an internal standard along with:~ the response factor relating area counts to concentration. (7) The measured tracer concentration is to be adjusted for any dilutions and then reported as ppm tracer. (8) The measured cutting fluid's concentration is to be adjusted for any dilutions and then reported as 21 (9) percent cutting fluid. August 3, 1992 A three-point calibration curve of tracer in toluene and crude oil will be run daily. Response factors will be calculated from the calibration curve and a running log of the calculated response factor versus time will be maintained daily.

Tests conducted with Point Mclntyre core used for damage testing indicte tracer recovery from the core is quantitative. 99.6% of the traCer was reCOvered'by the Dean Stark procedure.. Please note: The traCer could show up in the side arm and could also be foUnd in the toluene in.the core. The retained toluene volume in the core is . .. usually a small fraction of the total toluene so that is not a significant error. August 3,1992 EOU^TION 9 gives the saturation of plugging fluid in the core. This value will be printed out with the routine core data. Soh = (Wto*Cht/0,77)/Vp (9) The value, 0.777 g/cc, is standard value for the density of plugging oil, hexadecane. Contamination of cores by plugging fluid was 18.1% and 18.7% of the oil phase weight in two tests. These lab tests indicate there is some replacement of in-place oil by plugging fluid, but 75% of the oil originally present remained in the core afterPlugging~ This is very consistent with Exxon's findings for Prudhoe. ! EOUATION 10 gives the oil satUrati°n corrected' for mud filtrate and plugging fluid'in the core. This value will be printed out with the routine core data.

Teleco provided directional surveys and a gamma ray and dual propagation resistivity log. The gamma ray and resistivity log was used, through correlation, to identify lithologies, to pick formation boundaries, and to select casing and coring points. Logging service commenced at 11600 feet MD and was used to a depth of 15841 feet MD. The 7 3/4 inch DPR tools were used to log 3736 feet in 156.5 circulating hours. The 6 3/4 inch DPR tools were used to log 481 feet of hole and accumulated 24.5 circulating hours. III. DRILLING AND ENGINEERING III. DRILLING AND ENGINEERING This section briefly outlines the drilling activities involving Eastman Teleco on Prudhoe Bay Drilling's well #P2-50 located in the Point McIntyre field of the North Slope Borough, Alaska. A concise description on a run-by-run basis follows. Unless otherwise stated, all depths listed in this section are referenced to measured depth. RUN NO 1: 100 ft. to 4930 ft. TOOL NUMBER AND TYPE: 2246-36, 4X MILLER CODE DTF1 ' Directional service was initiated from the first run out of the conductor. Eastman Teleco's MWD was run in a steerable drilling assembly along with a Dynadrill F2000S 1.5 degree bent housing mud motor and a two cone Smith A1JSL bit. This bit drilled the entire 16 inch hole down to the 13 3/8 inch casing point. During this run, the well was kicked off in the proposed direction of S56.91E and built to an inclination of 67.5 degrees. Weight on bit for the run averaged 15 KLBS while sliding and 45 KLBS while rotating, with an average rotary speed of 60 RPMs. Strokes per minute for the run ranged between 140 and 163, giving a flow of 590 to 700 GPM with a surface pressure of 2500 to 3000 PSI. The run was ended at the surface casing point, with a final survey, taken at a depth of 4865 feet, showing an inclination of 67.5 degrees in the direction of S61.1E. RUN NO 2: 4930 ft. to 4930 ft. TOOL NUMBER AND TYPE: 2246-36, 4X MILLER CODE DTF1 This assembly was run to drill out the 13 3/8 inch casing shoe and begin the 12 1/4 inch hole section. While performing a surface pulse check, the circulation system pressured up with minimal flow, indicating a flow restriction. Upon inspection, it was found that the drillpipe screen was ripped apart and the top of the MWD tool was filled with rubber. The tool was laid down and a backup collar picked up. AUG 1 ?_ 199?- Alaska Oil & Gas C;ons. C;omm'm~'mn A~chomO~e RUN NO 3: 4930 ft. to 9479 ft. TOOL NUMBER AND TYPE: 272-61, 4X MILLER CODE DTF1 A Dynadrill 1 degree bent housing motor, a Smith MFDSHC bit, and another directional tool were run in the hole to begin the 12 1/4 inch intermediate hole section. After testing surface casing to 3000 PSI, 10 feet of new hole were drilled and a leakoff test was performed. This run was in the long hold section of the well, and it's intent was to hold the desired inclination of 65.3 degrees along the proposed azimuth of 123.09 degrees. Rotary drilling was employed to accomplish this, with occasional tool sets to the left as the hole had the slight tendency to walk right. Numerous short trips were made in order to keep the hole clean and reduce drag. During these wiper trips, the technique of upreaming while pulling out was used, as this tended to improve the overall effectiveness of the wiper trips. Despite these precautions, the flowline still packed off several times with clay. While rotary drilling, the weight on bit was held between 30 to 50 KLBS, with the rotary table turning 60 to 90 RPMS. Flow rates ranged from 675 to 760 GPM, with the surface pressure reading from 3000 to 3100 PSI. The run was ended at a depth of 9479 feet due to a low penetration rate. The final survey for the run was taken at 9332 feet and indicated 65.3 degrees of angle in the direction of S54.1E. RUN NO 4: 9479 ft. to 11600 ft. TOOL NUMBER AND TYPE: 2222-40, 4X MILLER CODE DDGTF4 For this run, Eastman Teleco's DDG service was used; DDG (Drilling Dynamics & Gamma) tools measure realtime downhole weight on bit, downhole torque, formation gamma rays, as well as directional parameters. This tool was run in the hole with a Smith D2000S combo mud motor (a 7 3/4 inch motor with a 9 5/8 inch bearing pack) with a 1 degree bent housing. The bit was a Smith MlSCL with a jet configuration of three 16's and one 12, for a TFA of 0.699. Unfortunately, the DDG tool suffered a failure in it's lower sub, and downhole weight and torque remained unreliable throughout the run; very little downhole weight and torque data was collected. The gamma sensor, however, remained operational and a complete realtime gamma tog was collected during run 4. Pump speed for this run ranged from 140 to 150 strokes per minute, giving a flowrate from 590 to 635 GPM. Surface pressures ran between 3100 to 3400 PSI. Weight on bit was held between 35 to 60 KLBS while rotating at 60 to 90 RPMs. Several zones of high torque were encountered during the course of this run, where the top drive drew a cyclical 600 to 1000 amps. The torque continued to increase as the well was drilled deeper and the vertical section increased. This assembly was pulled for low penetration rate at 11600 feet. The directional sensor appeared to be sending erratic azimuth data near the end of the run; however, tandem magnetic single shots dropped before pulling out of the hole confirmed the tool's accuracy. The final survey for the run was 66.4 degrees with an azimuth of 123.1 at a depth of 11486 feet. RUN NO 5: 11600 ft. to 13494 ft. TOOL NUMBER AND TYPE: 1757-54, 3X SPLIT PHASE BINARY DPRTF4 This run marked the beginning of DPR or Dual Propagation Resistivity logging service. Another Smith Combo motor was picked up, along with a Smith S856KP PDC bit. While tripping in the hole, a checkshot was made and the survey compared favorably with the previous tool. Very little mud motor sliding was required, as the well held the direction of 123 degrees and maintained an inclination between 65.6 and 67.5 degrees while rotary drilling. Mud weight was increased from 9.7 to 10.0 PPG. Rate of penetration varied between 10 to 100 feet per hour, but averaged about 35 feet per hour. 10 to 15 Klb were run on the bit, with rotary speed averaging 120 RPM. Pump output varied from 120 to 150 SPM (510 to 635 GPM), depending on whether or not both pumps were operational, with a maximum standpipe pressure of 3450 PSI. During periods of high rotational torque, the rig pumps would slow down when the top drive required more power; the erratic flow variations caused the high flow logging tool to power out. When the flow was steady, the tool would transmit good data. Two short trips and numerous low/high viscosity sweeps were used to keep the 65 degree hole clean. Torque continued to increase as the well got deeper, and mineral oil was added to the mud in an attempt to lubricate the hole. Torque increased to a cyclical 800-1050 amps during the run, and at 13494 feet the top drive motor burned up due to the high load. A trip was made to change BHA's, pick up a new bit, change out the top drive for the kelly, and to test BOPE. The Split Phase format used in this DPR tool showed considerable improvement over Miller Code in decoding through severe torque noise. AUG 1 2 199 - Anchorage RUN NO 6: 13494 ft. to 14037 ft. TOOL NUMBER AND TYPE: 1757-54, 3X SPLIT PHASE BINARY DPRTF4 A one degree bent housing motor along with a Smith M1SCL insert bit were used as the pendulum portion of this assembly in order to begin the drop section of the hole. The same DPR tool was included in the assembly. The kelly was picked up to replace the broken top drive. After drilling several joints and taking surveys, it became apparent that the hole was turning to the right at a rapid rate. Directional tool sets were made to the left, however the hole continued it's walk to the right even with continuous left hand sets. ROP's for the run, both while rotating and sliding, were good, averaging 35 to 40 feet per hour.' Weight on bit was 50 KLBS whle rotating 75 to 80 RPM's. Flow rates throughout the run averaged 550- 600 GPM at 130 to 140 SPM, with a pump pressure up to 3700 PSI. Torque was considerably reduced when the PDC bit of the previous run was replaced~with the roller cone bit. At a depth of 14037 feet, it was decided to come out of the hole due to the assembly's tendency to drop angle and walk to the right. The final survey for the run, taken at a depth of 13981 feet, showed an inclination of 51.8 degrees in the direction of S49.2E. RUN NO 7: 14037 ft. to 14795 ft. TOOL NUMBER AND TYPE: 1757-54, 3X SPLIT PHASE BINARY DPRTF4 For this run, another Dynadrill F2000S 1 degree bent hOusing motor was run along with a rebuilt Smith S-85 PDC bit. The objective of this run was to maintain direction and slowly drop angle until 30 degrees was reached; core recovery greatly .improves as the well approaches vertical. This assembly dropped from 51.8 degrees to 33.4 degrees while on bottom rotating, with very little motor sliding required; the direction walked left from S49.2E to S52.7E. After getting to bottom, drilling started with 550 GPM at 3500 psi. A torque increase was immediately seen due to the PDC bit. As more drill.pipe was added to the string, the standpipe pressure crept up to 4000 PSI, and the flow rate was reduced to 520 GPM to maintain 3800 PSI. Pressure drop charts.indicated a pressure drop'of only 50 PSI per 1000 feet for drillpipe, so some other problem for the abnormal pressure increase was present~ At this point, the DPR tool began to transmit spotty formation evaluation data due to the reduced flow. As requested by the operator, high flow turbines were used in the MWD collars, which operate best near their upper limit of 900 GPM. The highest flow rates used during DPR logging runs in this hole was 659 GPM, or well within the range of our standard flow rate tools (350-750 GPM). The surface pressure continued to increase as the flow was cut back more; at a depth of 14795 feet MD, the assembly was pulled since a good realtime resistivity and gamma log was needed to pick the casing point. The PDC bit had several jets plugged with rubber. The mud motor was laid down to reduce overall pressure drop so more fluid could be pumped; the rotary drilling assembly would be locked up to hold angle and direction. RUN NO 8:14795 ft. to 15336 ft. TOOL NUMBER AND TYPE: 1757-54, 3X SPLIT PHASE BINARY DPRTF4 A packed rotary assembly was used for this run, along with a mill tooth bit, in hopes of holding angle and direction until the total depth of the 12 1/4 inch hole was reached. The unrestricted jets of the new bit, combined with dropping off the mud motor, significantly reduced the overall pressure drop for this run and increased the available flow. A section of hole from 14535' to 14757' that was not logged during the previous run (due to low flow rates) was relogged at the beginning of this run. Upon reaching bottom and drilling new hole, penetration rates of 25 to 35 feet per hour, with a weight on bit of 45 KLBS, were attained for a total of 33 rotary drilling hours. Drilling was halted at the first sign of the HRZ shale, at a depth of 15336 feet. A final survey, at a depth of 15302 feet, showed an angle of 31.4 degrees and a direction of S47.0E. An increase in shale cuttings and gas prompted the company man to increase the mud weight from 10.0 to 10.3 PPG before coming out of the hole. While pulling out of the hole, tight spots were encountered, and the drill pipe became stuck at 7100 feet (4890 feet TVD). Jarring was attempted, and up to 450 KLBS over string weight was pulled; LVT 200 mineral oil and Sack Fishing Tool was spotted around the pipe. In an attempt to reduce differential sticking, the mud weight was cut back to 9.9 PPG. After running a freepoint tool and backing off above the BHA, fishing jars were screwed into the fish and the assembly was freed and recovered after jarring up for several hours. RUN No.9:15336 ft. to 15841 ft. TOOL NUMBER AND TYPE: 1639-32, 3X SPLIT PHASE BINARY DPRTF4 After setting 9 5/8" casing to a depth of 15336 feet MD., the mud was changed to an LVT-200 mineral oil base. The hole was then cored from the shoe to a depth of 15609 feet. At this point, a DPR tool was run in the hole to log the previously cored interval and pick the TD point for the hole. After reaching bottom, torque, which had been high on previous runs, was much reduced due to the oil base mud, averaging 650 amps. The rotary assembly was run with 40K weight on bit and 80 RPM's. ROP's averaged 20 feet per hour, and ranged between 5 and 35 ft/hr throughout the run. Flow rates were approximately 400 gallons per minute with 95 strokes per minute and a pump pressure of 3100 PSI. The well was ended at a depth of 15841 feet (9237 feet TVD). Final survey for this well was taken at a depth of 15801 feet, and showed an inclination of 30.1 degrees in the direction of S40.4E. IV. FORMATION EVALUATION IV. FORMATION EVALUATION P2-50 was an equity determination well drilled by Prudhoe Bay Drilling in the Point McIntyre field, located in the North Slope Borough of Alaska. DPR logging tools were used to correlate known stratigraphic markers in order to determine the 9 5/8 inch intermediate casing point and the TD of the well in the 8 1/2 inch hole. All depths referred to in this section are measured depths"from the kelly bushing. DPR logging services began in the 12 1/4 inch hole at a depth of 11550 feet (6712 feet TVD), near the top of the West Sak sands. These sands are located in the Prince Creek- Schrader Bluff Formation, a member of the Late Cretaceous Colville Group. The first heavy oil traces showed up at 11890 feet (6850 feet TVD), marking the top of the West Sak. Coarse sand grading into finer sand, along with numerous coal stringers, was seen from the top of the West Sak until 12800 feet (7200 feet TVD), where siltstone became more prominent. From 13300 feet (7400 feet TVD) down, mostly siltstone with small amounts of sand was logged. At 13593 feet (7533 feet TVD), a distinctive highly resistive streak was noted, and volcanic tufts were seen by the mudloggers. At a ,depth of approximately 14970 feet (8490 feet TVD), the K-10 marker was encountered. The K-10 marker was picked using the gamma ray in conjunction with resistivity log response. Gamma values showed a distinct decrease in initial values, then grading into a higher gamma zone, while the resistivity trace experienced an abruptly increasing spike over the same interval. Shortly below the K-10 marker, the K-5 marker appeared at a depth of 15046 feet (8555 feet TVD). This marker was seen on the log as a sharply ramping increase in the gamma trace after a short cooler zone and a corresponding drop off in resistivity values. Directly below the K-5 marker is a highly radioactive zone called the Shale Wall Member, which belongs to the Late Cretaceous Colville Group. The Shale Wall is not seen in all wells in this area; it is best characterized by consistently high gamma values, for an interval of 175 TVD feet in this particular well. Due to the active nature of all logging curves in this interval, good correlative points can be used to pick a casing point. At a depth of 15307 feet (8777 feet TVD), a dropoff in the resistivity measurements along with a sharp increase in gamma values showed the resistivity sensor (18 feet behind the bit) to be at the top of the HRZ. The well objectives called for the placement of casing so that the majority of the HRZ would be behind pipe and the entire underlying Kalubik formation could be cored directly below casing. Since the HRZ is very thin in the Point McIntyre field, as little as 20 TVD feet in some areas, this calls for good correlation of the HRZ top and the overlaying K-shales. Based on the above noted markers, the 12 1/4 inch hole was ended at a depth of 15336 feet MD. After setting 9 5/8 inch casing, 10 feet of 8 1/2 inch hole were drilled to perform a formation integrity test. The mud system was changed over from a lightly dispersed bipolymer mud to an LVT 200 mineral oil base mud. A trip was made to pick up a coring bit, and the next 263 feet of hole were cored in order to evaluate the reservoir parameters of the oil-water contact and the upper Kuparuk River sands. After the coring operations were completed, DPR logging tools were picked up, and the previously cored interval was logged while reaming to bottom. Logging while drilling continued to the TD point of the 8 1/2 inch hole. Below a depth of approximately 15450 feet (8900 'feet TVD), the beginning of a zone of a lower, flat response on the resistivity trace along with corresponding relatively flat gamma log was encountered. A noticeable marker appeared at a depth of 15780 feet (9180 feet TVD), consisting of a high resistivity bulge combined with a low gamma response. The hole was ended at a depth of 15841 feet (9237 feet TVD), and the 7 inch production liner was set in this shale section.

BIT RECORD INTRODUCTION P2-50, ONE OF A SERIES OF POINT NACINTYRE WELLS, BY THE PRUDHOE BAY DRILLING GROUP, IS LOCATED ON THE WEST DOCK PAD, APPROXIMATELY 12 NILES NORTH WEST OF PRUDHOE BAY, ALASKA ON THE SHORELINE OF THE ARCTIC OCEAN. THE COORDINATES FOR THE SURFACE LOCATION OF THE P2-50 WELL ARE: 495' FNL, & 1256' F~L, IN SECTION 14, T12N, R14E UNIAT NERIDIAN. THE MAIN OBJECTIVE FOR THIS WELL WAS TO DRILL A HIGH ANGLE DEVIATED HOLE TO THE SOUTHEAST DIRECTION FRON THE SURFACE LOCATION AND PENETRATE THE TOP OF THE TARGET, KUPARUK RIVER FORMATION, A LOWER CRETACEOUS AGE MEMBER OF THE UGNURAVIK GROUP, AT THE FOLLOWING COORDINATES: 1463' FNL, 265' FWL, IN SECTION 19, T12N, R15E UMIAT MERIDIAN AT A SUB SEA MEASURED DEPTH OF 15,513 FEET AND A TRUE VERTICAL DEPTH OF 8,878 FEET. PROPOSED BOTTON HOLE COORDINATES WERE: 1562' FNL, 429' I~L, IN SECTION 19, T12N, R15E UN. THE WELL PROGRAM WAS DESIGNED FOR THE BOTTON HOLE LOCATION TO BE AT AN ANGLE OF SOUTH 56.92 DEGREES EAST AND A DEPARTURE OF 11,620' WITH RESPECT TO SURFACE HOLE LOCATION. AN AVERAGE HOLE ANGLE OF 65 DEGREES, FRON TRUE VERTICAL, WAS REQUIRED TO LINE UP WITH THE TARGET SO THAT THE FINAL PENETRATION ANGLE WOULD BE AT 30 DEGREES PROM TRUE VERTICAL. A MAJOR OBJECTIVE, OF THE P2-50 WELL, WAS TO RECOVER APPROXIMATELY 260' OF LOW INVASION CORE FROM AND INCLUDING THE TOP BOUNDARY OF THE KUPARUK RIVER FORMATION SANDS. INTERMEDIATE 9-5/8*' CASING WAS SET JUST ABOVE THE KUPARUK BOUNDARY IN THE CRETACEOUS HRZ, AND THE FRESH #ATER BASED DRILLING MUD SYSTEM WAS CHANGED OVER TO LVT 200, A MINERAL OIL BASED MUD WITH LESS THAN 2Z WATER CONTENT, TO KEEP DRILLING FLUID INVASION DO~q TO A MINIMUM. THE STRATIGRAPHIC SEQUENCE PENETRATED BY THIS HOLE INCLUDED THE PERMAFROST, T-3, K-15, WEST SAK, K-10, K-5, HRZ, KALUBIK, AND KUPARUK RIVER FORMATIONS WITH FINAL WELL T.D.

DATA DISPLAYED ON THE LOG INCLUDES: LITHOLOGY, RATE OF PENETRATION, TOTAL GAS, CUTTINGS GAS, CHROMATOGRAPH DATA, RESISTIVITY AND GAMMA RAY DATA WAS IMPORTED FROM TELECO AT THE END OF EACH BIT RUN. TOTAL GAS, RATE OF PENETRATION, CUTTINGS GAS AND GAMMA RAY ARE PLOTTED LINEARLY, WHILE ALL OTHER PARAMETERS ARE PLOTTED LOGARITHMICALLY. LOGS WERE PLOTTED AS 2 INCHES PER 100 FEET (1:600), WITH THE EXCEPTION OF THE PRESSURE DATA LOG. DRILL DATA DRILLING DATA MONITORED INCLUDED: RATE OF PENETRATION (ROP) USING THE BLOCK HEIGHT SYSTEM, ROTARY SPEED, HOOKLOAD, WEIGHT ON BIT, TORQUE (MINIMUM, MAXIMUM, AND AVERAGE), MUD FLOW IN AND OUT, MUD TEMPERATURE IN AND OUT, STANDPIPE PRESSURE, CASING PRESSURE, l:q.~P STROKES, AND ALL PITS WERE MONITORED. ALSO THREE H2S STATIONS WERE MONITORED AT ALL TIMES. THIS DATA WAS PLOTTED ON THE LOGS AS WELL AS BEING DISPLAYED ON REMOTE TERMINALS. COMMUNICATION EXLOG PROVIDED ONSITE AND OFF LOCATION REMOTE TERMINALS FOR THE DISPLAY OF ALL DRILLING PARAMETERS. THERE WAS A RADIO MODEM CONNECTION WITH A REMOTE TERMINAL IN THE DRILLING OFFICE OFF LOCATION IN THE LIVING CAMP, AS WELL AS A REMOTE TERMINAL IN THE GEOLOGIST'S OFFICE AT THE WELLSITE. AN EXPLOSION PROOF DRILL MONITOR (HAD) WAS PROVIDED FOR THE DRILLER ON THE RIG FLOOR. SAMPLING 8AMPLE8 ~ERE COLLECTED AS PER THE DIRECTIONS RECIEVED FROM BOB DAWSON IN THE ARCO ALASKA OFFICES. THREE WET AND FIVE HRY SAMPLES WERE COLLECTED. 11550' - 14800' MD 14800' - TD 30 F(X)T SAMPLE INTERVALS 10 FOOT SAMPLE INTERVALS ALL SAMPLES WERE SHIPPED TO THE BAYVIEW GEOLOGIC FACILITY WAREHOUSE IN ANCHORAGE, IN CARE OF M.V. STANFORD. A COMPLETE LISTING OF SAMPLE SHIPMENTS CAN BE FOUND IN THE APPENDIX. -3- FORI~L~TION EVALUATION COMMENCE LOGGING AT 1400 HOURS, MAY 22, 1992 AT 6707 FEET TVD (11550 FEET MD) IN THE LATE CRETACEOUS. ALL DEPTHS, UNLESS OTHERWISE SPECIFIED, ARE FROM K.B. WHICH WAS 43 FEET ABOVE SEA LEVEL. WEST SAK INTERVAL LITHOLOGY THE WEST SAK 6850' - 8490' TVD (11890 - 14975' MD) ENCOUNTERED FIRST TRACE SHOWS OF HYDROCARBONS IN THE FORM OF MINOR SAMPLE FLUORESCENCE AND WEAK OR THIN CUT FLUORESCENCE, AT 6850' TVD (11890' MD), WHICH WAS THE APPROXIMATE TOP OF THE WEST SAK SANDS. THE PRESENCE OF HEAVIER HYDROCARBONS, AS EVIDENCED BY CHROMATOORZ~PH ANALYSIS, RESULTED IN A STRONGER; THOUGH STILL A TRACE, SHOW BEING LOGGED, STARTING AT 7010' TVD (12275' MD). THIS TRACE SHOW WAS LOGGED THROUGHOUT THE WEST SAK SANDS TO A DEPTH OF 8490' TVD (14975' MD). WHILE THE LITHOLOGY OF THIS INTERVAL IS GENERALLY SIMILAR TO A DEPTH OF ABOUT 7400' TVD; THAT IS PREDOMINATELY SAND INTERBEDDED WITH SILTSTONE, CLAYSTONE, AND THIN COALS; THE TOP OF THE WEST SAK SANDS MAY BE GENERALLY CONSIDERED AS INITIAL OCCURRENCE OF THE PERSISTENT TRACE SHOW OF HYDROCARBONS, IN THE P2-50 THAT POINT WAS AT 6850' TVD. FROM ABOUT 7410' TVD, (14890' MD) TO 8490' TVD (14975' MD), THE LITHOLOGY CONSISTED ALMOST EXCLUSIVELY OF SILTSTONE GRADING TO SHALE WITH MINOR SAND INTERBEDDING. THE MEDIUM GRAY AND GRAY-BROWN COLOR OF SILTSTONE GAVE WAY TO A DARK GRAY AND GRAY BROWN SHALE NEAR THE BOTTOM OF THIS INTERVAL. WORTHY OF MENTION, IN THIS INTERVAL, ARE TWO POINTS OF INTEREST IN THE AREA OF LITHOLOGY. FIRST THE OCCURRANCE OF A FLOOD OF INNOCERAMOUS PRISMS FROM 7210' TVD (12790' MD) TO 7230' TVD (12840' MD). THESE SHELLFRAGMENTS ARE GENERALLY USED AS AN IDENTIFYING MARKER FOR THE TOP OF THE K-5 ZONE (WHITE, CLEAR, OR TRANSLUCENT INOCERAMIJS) OR THE K-2 ZONE (TAN OR LIGHT BROWN INOCERAMUS) USUALLY CLOSE TO THE TOP OF THE HRZ. THE SECOND POINT OF INTEREST IS THE HIGH PERCENTAGE OF VOLCANIC TUFF ENCOUNTERED FROM 7520* TVD (13590' MD) THRU 7535' TVD (13620' MD). THE COLOR, CONSISTENCY, AND TEXTURE WERE ALL UNUSUAL FOR THE POINT MACINTYRE UNIT AND THEREFORE NOTEWORTHY AS A POSSIBLE MARKER FOR REFERENCE IN FUTURE WELLS. -4- DRILL RATE AND GAS DATA THE DRILL RATES RANGED FROM 5 TO 140 FEET PER HOUR THROUGH THIS HOLE SECTION. IT AVERAGED 60 FEET PER HOUR TO 14800* MD WHERE IT DROPPED TO AN AVERAGE OF 30 FEET PER HOUR. THE HOLE ANGLE HAD BEEN PREVIOUSLY KICKED OFF AT 500 FEET MD, AND BUILT UP TO A MAXIMUM ANGLE OF 67 DEGREES AT 9923 FEET MD~ WHERE THE ANGLE WAS HELD UNTIL 13545 FEET WHERE IT WAS ALLOWED TO DROP OFF TO 32 DEGREES AT THE END OF THIS HOLE SECTION, AND HELD THROUGH THE NEXT SECTION. DITCH GAS RANGED FROM 5 TO 150 UNITS IN THIS SECTION, AND AVERAGED 70 UNITS. HIGHER GAS READINGS OCCURED AT THE BOTTOM OF THIS SECTION, AND CONTINUED ON THROUGH THE HUE SHALES. C1 WAS PRESENT THROUGHOUT THE SECTION AND C2 WAS OCCASIONALLY PRESENT FROM FROM 11550 TO 12280* MD. C1 THROUGH C4 WAS PRESENT FROM 12280 TO THE END OF THIS SECTION. OIL AND GAS SHOWS ONE LONG TRACE OIL SHOW CHARACTERIZED THE ~EST SAK SANDS IN P2-50, THROUGHOUT THIS HOLE SECTION FROI~ 11890 TO 14975 FEET ~D. THERE WAS LITTLE VARIATION IN THE OIL SHOW AND MAY BE DESCRIBED AS HAVING FROM 5Z TO 50Z DULL GOLD SAI~PLE FLUORESCENCE, A WEAK GREEN TO YELLOW SLOW CUT FLUORESCENCE, NO VISIBLE CUT, AND NO RESIDUAL RING AFTER EVAPORATION OF THE CUTTING AGENT. OCCASSIONALLY A SLIGHTLY STRONGER TRACE SHOW WAS ENCOUNTERED WITH A PALE YELLOW STREAI~ING CUT FLUORESCENCE WITH A LIGHT STRAW TO STRAW VISIBLE CUT AND A LIGHT BROWH RESIDUAL RING. A SHOW REPORT WAS WRITTEN ON THIS SECTION, ALTHOUGH THE WEST SAK IS GENERALLY NOT CONSIDERED AS BEING A POTENTIAL RESERVOIR, THE RATING GIVEN THE SHOW WAS POOR. SEE APPENDIX FOR SHOW REPORT #1. -5- HUE SHALE SECTION (K10, KS-SHALE WALL, HRZ) LITHOLOGY THE HUE SHALE CONTAINING THE K-10, K-5, K-2, AND HRZ COMMENCED AT 8490' TVD (14890' ~I)) AND CONTINUED TO 8840' TVD (14380' ND). IT CONSISTED FIRST OF THE K-10 ZONE, ONLY 65' ND THICK. WHILE SHOWS OF OIL WERE PRESENT AND BACKGROUND GAS INCREASED IN THIS ZONE, THE CONCLUSIVE METHOD OF PICKING THE TOP OF THIS ORGANIC SHALE IS BEST ACCOMPLISHED BY THE GAI~ RAY MWD LOG. THE K-5 ZONE FOLLOWED AT A DEPTH OF 8555' TVD (15035' ND). ALSO A SOURCE ROCK, IT WAS STONGER STILL IN HYDROCARBON CONTENT AND BOTH STRONGER OIL SHOWS AND INCREASED BACKGROUND GA~ WERE NOTED. THROUGHOUT THE K-10 AND K-5, THE SHALE CUTTINGS SAMPLES BECAME DARKER GRAY AND EXHIBITED THE "PAPER SHALE" QUALITIES WITH INCREASINGLY HIGHER PERCENTAGES. THE BALANCE OF CUTTING SAMPLES CONSISTED OF MEDIUM TO DARK GRAY SILTSTONE, A TRACE TO 10% SANDSTONE, TRACES OF PYRITE AND TUFF WERE PRESENT ALSO. DRILL RATE AND GAS DATA THE DRILL RATES RANGED FROM 20 TO 105 FEET PER HOUR IN THIS HOLE SECTION. THE AVERAGE DRILL RATE WAS 35 FEET PER HOUR. THE HOLE ANGLE WAS HELD TO 32 DEGREES THROUGH THIS INTERVAL. THE DITCH GAS RANGED FROM 60 TO 200 UNITS, AND AVERAGED 140 UNITS. THIS WAS DOUBLE THE PREVIOUS HOLE SECTION, AND THE INCREASE TOOK PLACE AT THE CONTACT OF THESE TWO FORMATIONS. C1 THROUGH C4 WAS PRESENT THROUGHOUT THIS INTERVAL. WHILE TRIPPING OUT TO RUN E LOGS THE PIPE BECAME STUCK AT 7100' ND. JARRED FISH OUT AFTER PICKING UP A SET OF FISHING JARS. TRIP GASES AFTER REAMING BACK TO BOTTOM WERE 2453 UNITS, AND 3175 UNITS AFTER A SHORT TRIP TO THE SHOE. BACKGROUND GAS AVERAGE ROSE TO 250 UNITS, THIS WAS MOSTLY TO DO WITH THE SPF SPOTTED AROUND THE FISH. 9 5/8" CASING WAS SET AT 15336' MD. OIL AND GAS SHOWS AS IN THE WEST SAK, THERE WAS FREE OIL, CUT, AND FLOURESCENCE THROUGHOUT THE INTERVAL. ALTHOUGH, THE LITHOLOOY OF THIS SECTION WAS LOGGED AS TO IOOZ SHALE AND SlLTSTONE, THE STRENGTH AND CHARACTER OF THE CONTINUOUS SHOW INCREASED CONSIDERABLY AND ONLY THE LACK OF RESERVOIR TYPE ROCK KEPT THE SHOW RATING TO A POOR EVALUATION. A SHOW REPORT WAS ALSO DONE ON THIS SECTION, BUT GIVEN A POOR RATING, DUE PRIMARILY TO THE CONSIDERATION THAT THIS IS A MAJOR SOURCE ROCK FOR THE REGION AND NOT GENERALLY REGARDED AS A RESERVOIR. SEE APPENDIX FOR SHOW REPORT #2. -6- KALUBIK AND KAPARUK SECTION LITHOLOGY THE BOTTOM OF THE HUE SHALE (THE BOTTOM OF THE HRZ SPECIFICALLY) AND CONVERSELY THE TOP OF THE KAPARUK (KALUBIK?) WAS ENCOUNTERED IN CORE #2 AT A DEPTH OF 8841' TVD (15381' MD). THE CUTTING SAMPLES WERE HIGHLY CONTAMINATED BY CEMENT CUTTINGS FROM 15338' TO 15390' MD. FOLLOWING THE DISAPPEARANCE OF CEMENT AS AN IMPEDIMENT TO VISUAL IDENTIFACATION, FURTHER DIFFICULTY WAS ENCOUNTERED. SHALE AND SILTSTONE FROM THE FORMATION BETWEEN THE 9 5/8" CASING SHOE AND THE TOP OF THE KUPARUK (KALUBIK?), MASKED THE CUTTINGS. THE DRILLING FLUID USED FOR CORING (LVT200 VERSACORE) ALSO MASKED THE SHOWS AND SAMPLE. AS WELL AS THE AMOUNT OF CUTTINGS PRODUCED BY THE CORE BITS, WHICH WAS MINIMAL. THE SAND THAT WAS SEEN IN THIS INTERVAL WAS A VERY FINE TO FINE GRAINED SAND, AND VERY SILTY, OFTEN GRADING TOWARDS A SILTSTONE. THE SORTING WAS POOR TO MODERATE, THERE WAS NO VISUAL POROSITY. BUT FOR THE MOST PART, THE SAMPLES CONSISTED OF SHALES AND SILTSTONES. DRILL RATE AND GAS DATA THIS ENTIRE SECTION WAS CORED WITH A 8.5" CORING ASSEMBLY. THE DRILL RATES RANGED FROM 2 TO 54 FEET PER HOUR, AND AVERAGED 15 FEET PER HOUR. THE HOLE ANGLE IN THIS HOLE SECTION WAS HELD AT 30.5 TO 32 DEGREES. THE DITCH GAS IN THIS SECTION WAS 5 TO 50 UNITS. THE AVERAGE DITCH GAS WAS 20 UNITS. C! THROUGH C4 WAS PRESENT IN THE ENTIRE SECTION. OIL AND GAS SHOWS THERE WAS A SHOW REPORT WAS DONE ON THIS SECTION, BUT THE RESULTS ARE OBSCURED BY THE POOR QUALITY OF CUTTING SAMPLES AND THE USE OF A OIL BASE MUD HINDERS THE EVALUATION OF THE CUTTINGS. THE SHOW WAS GIVEN A POOR RATING DUE TO THE MIXED RESULTS AND THE LACK OF VISUAL POROSITY IN THE SAND THAT WAS ENCOUNTERED. SEE APPENDIX FOR SHOW REPORT #3. -7- MILUVEACH SECTION LITHOLOGY THE TOP OF THE MILUVEACH WAS ENCOUNTERED AT 15512' MI) IN CORE #4. IT WAS EASILY RECOGNIZABLE BY A COLOR CHANGE TO BROWN TO DARK BROWN, OCCASIONALLY DARK GRAY BROWN. THE DRILL CUTTINGS BECAME BLOCKY WHICH IS ANOTHER INDICATOR OF THE MILUVEACH. THERE WAS ALSO FAIR AMOUNTS OF MICA AND SUB ROUNDED QUARTZ'PEBBLES. AT A DEPTH OF 15710, GRAY CLAY BEGAIN TO SHOW UP IN THE SAMPLES, THE SHALES AT THIS POINT BECAME FIRMER AND MORE BRITTLE. THROUGHOUT THE SECTION THE THE SHALES WOULD RANGE FROM NON SILTY TO VERY SILTY. THE WELL TD WAS IN THE MILUVEACH AT A DEPTH OF 15841* MD (9238* TVD) DRILL AND GAS DATA THE DRILL RATES IN THIS SECTION WERE VERY CONSISTENT, IN THE TOP SECTION THAT WAS CORED, THE RATES WERE 3 TO 15 FEET PER HOUR, WITH AN AVERAGE OF 12 FEET PER HOUR. THE NEXT SECTION RANGED FROM 4 TO 40 FEET PER HOUR, WITH AND AVERAGE OF 17 FEET PER HOUR. THE GAS DROPPED OFF IN THIS SECTION AND RAN FROM 8 TO 22 UNITS, AND AVERAGED 10 UNITS OF DITCH GAS. C1 THROUGH C3 WAS PRESENT THE ENTIRE SECTION, C4'S DROPPED OUT AT 15620*. OIL AND GAS SHOWS NO OIL OR GAS SHOWS WERE ENCOUNTERED IN THIS SECTION OF THE HOLE. -8- APPENDIX I.
