The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Anna Dube, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator s ~- BP Exploration (Alaska) Inc.

Only slight increase in rate. Rate at 58 MMcfd and dropping. Instrumentation recalibrated pressure transducer P100P8021. Pressure off by 45 psi on the high side. Pumped water wash as follows: 5 BBLs Methanol, 550 BBLs 2% KCL water w/ 2 GPT DS F75N surfactant at (110° F), 5 BBLs methanol. Treating pressures indicated a formation break at a pressure of 2300 psi at 8 BPM. Took 15 mins after shutting down the pumps to get the gas injection started up. Tubing pressure had dropped down to 900 psi. After pushing the liquid out of the tubing the rate was 108 MMCFD at 4025 psi. One hour after gas reached the perfs the rate fell off and the pressure came up to pre treatment conditions. Rate and pressure response indicative of reaching a fracture closeure. Ran step rate test. Max injection rate of 49.5 MMCFD @ 4590 psi. Shut well in at 2023 hrs for surface pressure falloff. On line at 1900 hrs at 4500 psi and only 23 MMcfd rate. Lost about 50% of injectivity from pre shut in to post shut in. Wireline made bailer tag run and SBHP survey. PBTD = 8743' cor MD. BTM perfs at 8710' md, and 33' of rat hole. Pressure survey showed cooling across the intire perfed interval indicating that all of the perfs were open. BHT = 100° F, BHP 6 hrs after SI= 4282 psia at 8400' SS. Wireline pulled SSSV and ran Frac sleeve. Pumped propped hydraulic fracture treatment. Unable to set tree saver, had to add a 34" extension to get a set. Pumped data frac at 40 BPM and 2100 psi. Added 150 BBLs to pad. Pumped treatment at 40 BPM and 2100 psi. Pad vol = 1160 BBLs 40# cross linked guar gel, Slurry vol = 285 BBLs 40# cross linked guar gel, did not screen out, total proppant in formation of 32,213# 20/40 carbo-lite. Closure = 4,960 psi (0.574 psi/fi). Wireline pulled frac sleeve. Tagged PBTD at 8702' SLMD. Ran SSSV (WRDP-2). Freeze protected tubing w/92 BBLs 50/50 methanol water. R C .IV D Gas Cons.

Anchorage, Alaska 99518-3045. (907) 349-3541. Fax (907) 344-2823 INTRODUCTION Core Laboratories was requested to perform a core analysis study on behalf of Arco Alaska, Inc. for samples recovered from the Point McIntyre P1-G1 well from the North Slope, Alaska. Presented herein are the results of this study. Conventional cores cut with an water based mud were processed on site by Core Laboratories and Arco personnel. A service description and methodology are presented in section 1. The core analysis results and lithological descriptions are presented in section 2. A statistical summary and plot are presented in section 3. Appendices can be found in section 4. In conjunction with the report, the tabular results of the analysis are supplied on a IBM compatible diskette. We sincerely appreciate this opportunity to be of service and hope the data proves beneficial in the development of this reservoir. TABLE OF CONTENTS Section 1 2 3 4 5 CONVENTIONAL CORE ANALYSIS, SERVICE DESCRIPTION CONVENTIONAL CORE ANALYSIS, TABULAR RESULTS CONVENTIONAL CORE ANALYSIS, STATISTICAL AND CORE GAMMA DATA APPENDIX DATA DISKETTE SECTION 1 CONVENTIONAL CORE ANALYSIS SERVICE DESCRIPTION SECTION 1 CONVENTIONAL CORE Fi el d Procedures Conventional coring equipment in conjunction with a water based drilling fluid was used to extract core samples during November of 1992. All cores were taken using aluminum inner core barrels. Core Laboratories~ field personnel assisted with core preservation and handling. Sample points for plugging at Anchorage 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, assisted with the selection of samples. 4. Wrapped, dipped, and boxed preserved core pieces. 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 I and 2, 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 taken to the core trailer. Upon arrival of the core at the core trailer a Core Lab representative pushed the core out of the inner barrel and fit the core together. The core was oriented with the apparent up dip at the top, and depths marked on the core. Sample intervals were marked on the core at the wellsite. A three inch section near the foot mark was marked "SC", and a plug sample site was marked on the end nearest the foot mark. No "SC" sample site was allowed within one inch of a fracture in the core. Additional sample sites, designated as "R", were chosen from some intervals not already chosen using the "SC" criteria. Once the samples were designated and marked the entire core was wrapped using saran wrap and foil and dipped in Core Seal. The core was then placed in boxes which were marked, taped, and crated for shipment to Core Laboratories~ Anchorage facility. Please refer to the appendix for a more complete description of the wellsite 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 "SC" and "R" samples selected at the wellsite were depreserved and 1.5 inch horizontal plugs were drilled with a brine specified by ARCO. Where possible additional plugs were taken from intervals not designated at the wellsite to provide a more complete data set. The plugs were immediately loaded into the Dean-Stark apparatuses or, if no Dean Stark units were available for immediate use, were wrapped in saran wrap and aluminum foil and placed in jars for minimum exposure. The remaining whole core was then rewrapped in saran wrap and foil, and dipped in CoreSeal. The sampling completed, the core was depreserved 10 feet at a time, oriented with the top of the bedding up, 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. A more complete description of the core processing procedures can be found in the appendix. Core Photographs Approximately 15 feet of the cleaned 1/4 slabbed sections appears in each photograph. Six sets of visible spectrum flash and six sets of ultraviolet light photographs appear in separate binders. Conventional Analysis Techniques Core analysis methods as specified by Arco were used throughout the sampling process. Several changes to the procedures were instituted during the process, as noted below. CUTTING AND TRIMMING CORE PLUGS, page 11-13 Original: Calls for placing sample numbers on plug and end pieces. Change: Given the 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 bags (and thimbles after Dean Stark analysis) 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. Plug ends were placed in numbered bags. Original: Refers to the chloroform-methanol cleaning equipment as Dean Stark gl assware. 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. Dean-Stark Fluid Saturation Measurements Water was extracted from the samples by Dean-Stark technique using toluene in cleaned apparatuses. Extraction continued until no change in water volume was observed over a four hour period. Minimum extraction time was twelve hours. Samples were removed from the water Dean-Starks and placed in cleaning Dean Stark units containing 87 volume% chloroform - 13 volume% methanol cleaning solution. Cleaning continued until the cleaning solution showed no crude oil color. Extracted samples were dried in a 180 degrees F. vacuum oven for a minimum of 24 hours and until sample weights were constant to 0.01 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 (1) 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 Wgl = Weight of Grains Lost During the Process Wpb = Dry, Stable Weight of the Plug plus the Arco Prescri bed Bag W2 = Extracted and Dried Weight of the Sample (2b) 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 Porosity The horizontal plug samples were measured for bulk volume by mercury displacement at ambient conditions. Porosity was calculated using Equation 4.

August 3, 1992 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 . o . e 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. 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. Laboratory staffing and equipment must be adequate to meet core analysis timing requirements. o 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.

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 ° - 330 oF). 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 coting trailers will be required for wells with on-site plugging. ARCO will provide trailers. Trailer 1 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, routine 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 the foot marker. These samples 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 ..Overview 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 cored. August 3,1992 Below are the procedures which are planned for the quality control wells. These procedures will apply for the first two wells: . , 6, Conduct coring in the usual manner in order to achieve Iow 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. Mafk it with the initials SCF. Immediately preserve all core, including the dry sawed sections, in Saran wrap and aluminum foil as described later in more 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 SCF 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 orientation. 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 all 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. 5 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 SLABBED FAC i i 1.5" X 1.5" PLUG 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 10-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 Oilsorbent 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 ~-~2 7/8" 1.25" END PIECE ]CORE PLUG ~1~ 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 I 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. ROUTINE CORE ANALY~I~; 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. ~ !. ,~ ~ ~uo.,,st 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 l 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 1 and 2 identify sample types, sample and data frequency. , All 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. , 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. , 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 200 APl 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 1- inch slab from the whole core. Double s .tripe 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 10 August 3, 1992 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 '~-'~2 7/8" 1.25" le5el IEND PIECE ROUTINE ICORE PLUG .5II 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 1-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 fr6m 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 perforrned. - .... . 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. All Other Cores If the well is not-designated quality control, the routine core plugs will be Cut once-every'foot. ':Wh0le core samples for routine analysis have been dry-sawed each foot from the core and .preserved separately at the well. :If core plugs are taken at the well site then none will be taken in Anchorage. : Immediately after completing the core gamma, separate SC sections. 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. All 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 10st identification and breakage 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. 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 _+0.001 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 @ 10'7o 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 Plano, 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. 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 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 low 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 to determine 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 mercury 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! Vp Vpc - Ws Wgl = Wd - Wthi - Wbi - Ws 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 Plano 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. ' - ~-~ ' August 3, 1992 Core Slabbing Core slabbing may be conducted when the schedule permits and when the Operating Company representative decides. The core-,,',,ill 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 `,,,,ill 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 dept. h 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 be. 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.

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 ml 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.

Analytical Procedure (1) Upon receipt each sample bottle is weighed to the nearest tenth of a gram and recorded in a sample log book. The samples will be refrigerated at all times when not being processed. (2a) A 015 ml aliquot of each sample is diluted 1:1 by volume with the internal standard solution (i.e., 2 ppm Iododecane and 1.0 % Squalane in Toluene). (2b) (3) (4) 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. 5.0 gl of the sample/internal standard blend is injected into the GC splitter via the auto sampler and data acquisition is initialized. 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 concentration 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) From the FID, the' concentratiOn 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 (9) August 3, 1992 percent cutting fluid. 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.

EOUATION 7 gives the calculation of filtrate Weight fraction in the oil in the core. rf ' (7) EOUATIQN ~ gives the saturation of filtrate in the core. This value will be printed out with the routine core data. ~ d Sof = 100*(Wo*Ff/0.85)/Vp (8) . The value, 0.85 g/cc, is an average value for the density of the oil which is a combination of plugging oil, 0.77 g/cc, filtrate, 0.82 g/cc, and crude oil, 0.875 g/cc. the composition assumed is 20 % plugging oil, 10 % filtrate and 70 % stock tank oil by weight. This value can be refined, if needed, since the oil phase will be chromatographi'cally analyzed..There are no significant assumptions in the calculations except that reCovery of the tracer is quantitative and no losses when cutting plugs. Tests conducted with Point Mclntyre core used for. damage testing indicate 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 als° 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 EOUATION 9 gives the saturation of plugging fluid in the core. This value will be printed out with the routine core data. $oh = (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 after plugging. This is Very consistent with Exxon's findings for Prudhoe. EOUATION 10 gives the °il saturation correCted for mud filtrate and plugging fluid in the core. This value will be printed out with the routine core data. So corr = So - $0f -~ Sob (10) Core Labs should provide a spread sheet of all weights measured in the core analysis.

LOGS INTRODUCTION THE PI-G1 WELL IS ONE OF A SERIES OF POINT McINTYRE DELINEATION WELLS, DRILLED ON THE PM1 PAD, APPROXIMATELY 12 MILES NORTH WEST OF PRUDHOE BAY, ALASKA. COORDINATES FOB THE SURFACE LOCATION OF THE WELL ARE: 1241' FSL & 400' FEL, IN SECTION 16, T12N, R14E UMIAT MERIDIAN. PROPOSED BOTTOM HOLE COORDINATES WERE: 1315' FSL & 1292' FEL, IN SECTION 16, T12N, R14E UMIAT ~ERIDIAN. THE MAIN OBJECTIVE OF THIS WELL WAS TO TEST THE RUPARUK RIVER FORMATION, A LOWER CRETACEOUS AGE MEMBER OF THE UGNURAVIK GROUP, AT A PROJECTED DEPTH OF 8600' SUB SEA TRUE VERTICAL; THROUGH, THE RECOVERY OF LOW INVASION CORES OVER THE ZONE OF INTEREST AND BY ELECTRIC LOG ANALYSIS UPON THE COMPLETION OF DRILLING. PROJECTED TARGET (KUPARUK RIVER) COORDINATES WERE: 1315' FSL & 1292' FEL, IN SECTION 16, T12N, R14E UM. THE PROPOSED TARGET WAS REACHED BY DRILLING A DEVIATED HOLE; THROUGH THE USE OF DIRECTIONAL DRILLING TOOLS AND TECHNIQUES. THE WELL PROGRAM WAS DESIGNED FOR THE KICK-OFF TO START AT ABOUT 6400' MD AND TO GRADUALLY BUILD ANGLE TO 26 DEGREES FROM TRUE VERTICAL. IT WAS PROPOSED TO HOLD THE ANGLE UNTIL 8610', AT WHICH POINT THE ANGLE WOULD BE DROPPED TO A FINAL HOLE ANGLE OF 20 DEGREES FROM VERTICAL. THE ~ELL PROGR.&M WAS DESIGNED TO SET 9-5/8 INCH CASING JUST ABOVE THE TOP OF THE NUPARUK AND TO CHANGE OUT THE FRESH WATER BASED DRILLING MUD TO A WATERBASED BLAND CORING FLUID. THE PROJECTED STRATIGRAPHIC SEQUENCE PENETRATED BY THIS HOLE INCLUDED THE PERMAFROST, T-3, K-15, WEST SAK, 1-10, HRZ, KALUBIK, AND KUPARUK RIVER FORMATIONS WITH PROPOSED FINAL WELL T.D. IN THE LOWER CRETACEOUS MILUVEACH FORMATION.

THE SYSTEM IS A COHPUTEg BASED DATA COLLECTION UNIT, USED IN ACQUISITION, COHPILATION AND OUTPUT OF DATA. ADDITIONAL LITHOLOGIC AND HYDROCARBON EVALUATION WAS PROVIDED BY EXLOG'S ONSITE GEOLOGISTS. METHODS OF ANALYSIS USED FOB EVALUATION ABE PRESENTED IN EXLOG'S MANUAL "MUDLOGGING: PRINCIPLES AND INTERPRETATIONS" (MS-196). MUDLOG THE MUDLOG FORMAT WAS PREVIOUSLY ESTABLISHED ON FORMER POINT McCINTYRE WELLS LOGGED BY EXLOG. DATA DISPLAYED ON THE LOG INCLUDES: L£THOLOGY, RATE OF PENETRATION, TOTAL GAS, CUTTINGS GAS, CHROMATOGRAPH DATA, RESISTIVITY AND GAMMA RAY DATA WAS IMPORTED FROM ANADglLL AT THE END OF EACH BIT BUN. TOTAL GAS, BATE OF PENETRATION, CUTTINGS GAS AND GAMMA RAY ARE PLOTTED LINEARLY, WHILE ALL OTHER PAR~&X'!ETERS ARE PLOTTED LOGARITHMICALLY. LOGS WERE PLOTTED AS 2 INCHES PER 100 FEET (1:600), WITH THE EXCEPTION OF THE PRESSURE DATA LOG (2 INCHES PER 500 FEET/l:3000). DBILL DATA DRILLING DATA MONITORED INCLUDED: gATE OF PENETRATION (ROP) USING THE KELLY 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, PUMP 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 FOB THE DISPLAY OF ALL DRILLING PARAMETERS. THERE WAS A RADIO MODEM CONNECTION WITH A REMOTE TERMINAL IN THE RADIO ROOM OFF LOCATION IN THE AUDI#2 CAMP, A REMOTE TERMINAL IN THE GEOLOGIST'S OFFICE AT THE WELLSITE, AS WELL AS A REMOTE TERMINAL IN THE COMPANY MAN'S OFFICE. AN EXPLOSION PROOF DRILL MONITOR (HAD) WAS PROVIDED FOR THE DRILLER ON THE RIG FLOOR. SAMPL I NG SAMPLES WERE COLLECTED AS PER THE DIRECTIONS RECIEVED FROM BOB DAWSON tN THE ARCO ALASKA OFFICES. THREE WET AND FIVE DRY SAMPLES WERE COLLECTED. 6440' - 7980' MD 7980' - TD 30 FOOT 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 S.&MPLE SHIPMENTS CAN BE FOUND IN THE APPENDIX. -3- FORMATION EVALUATION COmmENCE LOGGING AT 0845 HOURS, NOVEMBER 8, 1992 AT 6440 FEET TVD (6439 FEET MD) IN THE LATE CRETACEOUS. ALL DEPTHS, UNLESS OTHERWISE SPECIFIED, ARE FROM K.B. wHICH WAS 52 FEET ABOVE SEA LEVEL. ALL FORMATION TOPS ARE UNCONFIRMED AND APPROXIMATE. WEST SAK INTERVAL LITHOLOGY THE WEST SAK 6619' - 8284' TVD (6621' - 8414' MD) THE WEST SAK IN THE PI-G1 WELL CONSISTED OF THREE SOMEWHAT DIFFERENT ZONES. THE FIRST, OR UPPER, ZONE ENCOUNTERED WAS FROM 6440' TO 7060' TVD (6440' - 7040' MD). THIS ZONE CONTAINED A HIGH PERCENTAGE OF SANDSTONE, UNCONSOL- IDATED SAND AND CONGLOMERATE, WITH ABUNDANT SILT AND CLAY MATRIX. THE SAND- STONE WAS VERY FINE TO FINE GRAINED QUARTZITIC SANDSTONE, WITH COMMON CALCITE CEMENT. UNCONSOLIDATED COARSE GRAINED QUARTZ SAND AND LITHIC PEBBLES WERE ALSO VERY ABUNDANT IN THIS ZONE. ABUNDANT SILT AND CLAY WERE ALSO PRESENT PRESU~IABLY AS MATRIX FOR THE UNCONSOLIDATED SAND AND CONGLOMERATE. CONMON TO ABUNDANT SHALE, SILTSTONE, AND MUDSTONE WERE ALSO OBSERVED. TRACES OF PYRITE AND WHITE - GRAY VOLCANIC TUFF WERE PRESENT IN THIS INTERVAL. FROM 7060' TO 8220' TVD (7060' - 8340' MD) THE WEST SAR WAS COMPOSED OF A MEDIUM GRAY TO GRAY BROWN CARBONACEOUS SILTSTONE AND SHALE. COMMON SANDY SILTSTONE AND SANDY SHALES WERE ALSO OBSERVED. WITH OCCASIONAL SAND AND SANDSTONE INTERBEDS. UNCONSOLIDATED LITHIC AND QUARTZ GRAINS AND BROKEN PEBBLES WERE PRESENT THROUGHOUT THIS MIDDLE ZONE OF THE WEST SAK, BUT NOT TO THE DEGREE SEEN IN THE UPPER INTERVAL. TRACE AMOUNTS OF PYRITE AND VOLCANIC TUFF WERE CO%MON THROUGHOUT THIS INTERVAL. RARE INOCER'AMUS PRISMS AND COAL WERE SEEN BELOW 6880' TVD (6900' MD). MORE COMMON INOCER~MUS PRISMS WERE NOTICED AT ?350' TVD (?350' MD), BUT THE CHARACTERISTIC "FLOOD" OF INOCERAMI WAS NOT OBSERVED IN CUTTINGS S~PLES. FROM 8220' TO 8285' TVD (8340' - 8415' MD) A FAIRLY DISTINCT SILTY SANDSTONE !NTERBED WAS ENCOUNTERED, WITH SHALEY INTERBEDS ABOVE AND BELOW THE SANDSTONE. THE SANDSTONE WAS LIGHT GRAY TO GRAY BROWN, WHITE AND COMPOSED OF FINE GRAINED QUARTZ WITH ABUNDANT SILTY MATRIX AND POSSIBLE SIDERITE CEMENT. VISIBLE POROSITY IN THIS SANDSTONE WAS ONLY FAIR, DUE TO THE LARGE AMOUNTS OF MATRIX AND CEMENTING AGENTS. IT SHOULD BE NOTED HERE THAT IT IS UNCLEAR, AT THIS POINT IN TIME, IF THIS SANDSTONE INTERVAL IS PART OF THE WEST SAK OR A DIFFERENT FORMATION ALTOGETHER. DRILL RATE AND GAS DATA DRILL RATES IN THE WEST SAK RANGED FROM 15 TO 350 FEET PER HOUR. IN THE UPPER ZONE (SAND/CONGLOMERATE), RATES RANGED FROM 20 TO 350 FEET PER HOUR WITH AN AVERAGE RATE OF PENETRATION OF APPROXIMATELY 80 FEET PER HOUR. IN THE MIDDLE ZONE, CHARACTERIZED BY SILTSTONE AND SHALE, DRILL RATES RANGED FROM 15 TO 150 PER HOUR. RATES IN THE MIDDLE WEST SAK, HOWEVER, GENERALLY SHOWED LITTLE DEVIATION FROM A 50 FOOT PER HOUR AVERAGE. THE LOWER WEST SAK (UN-NAMED SANDSTONE?), RANGED IN DRILL RATES FROM 10 TO 140 FEET PER HOUR, AVERAGING 70 FEET PER HOUR. LITTLE SLIDING (NON-ROTARY DRILLING) WAS DONE IN THE WEST SAK IN ORDER TO OBTAIN OR KEEP THE PROPER HOLE INCLINATION AND AZIMUTH ONCE ANGLE WAS ESTABLISHED. AREAS WHERE SLIDING WAS DONE EXHIBITTED MORE IRREGULAR DRILL RATES, BUT AVERAGE DRILL RATES WERE NOT SIGNIFICANTLY DIFFERENT FROM THOSE PREVIOUSLY MENTIONED. DITCH GAS RANGED FROM 15 TO 1250 UNITS IN THE WEST SAR, AND AVERAGED 75 UNITS. HIGHER GAS READINGS OCCURRED IN SEVERAL AREAS OF THE UPPER WEST SAK DUE TO THE SOMEWHAT UNEXPECTED PRESENCE OF MODERATE AMOUNTS OF HYDROCARBONS. A PEAK GAS BEADING OF 1250 UNITS WAS EXPERIENCED IN THE LOWER UN-NAMED SANDSTONE (STUMP ISLAND?) BUT NO OIL SHOW OCCURRED. HIGH C1 THROUGH C4 WAS PRESENT THROUGHOUT MUCH OF THE SECTION, WITH ONLY OCCASIONAL ABSENCE OF C4 IN AREAS OF LOW TOTAL GAS READINGS. OIL AND GAS SHOWS TRACE VERY DULL YELLOW TO GOLD ORANGE SAMPLE FLUORESCENCE AND A VERY SLOW STREAMING DULL YELLOW CUT FLUORESCENCE WAS PRESENT THROUGHOUT THE ENTIRE WEST SAK. TRACE IO FAIR .k~IOUNTS OF DARK BROWN "TARRY" OIL WAS NOTICED IN THE SAMPLES BELOW 6845 FEET TVD (6850 FEET MD). THIS OIL WAS SEEN STAINING SANDSTONES AND SILTSTONES WITH POOR VISIBLE POROSITY AND A SHOW WAS NOT RATED. HOWEVER, THE PRESENCE OF OIL IN THIS ZONE GENERATED ENOUGH INTEREST TO JUSTIFY A MEMORY LOG PASS BY IHE SPERRY-SUN MWD TOOL. THE UN-NAMED SANDSTONE, IN THE LOWER WEST SAK, WHILE HAVING A HIGHER GAS READING, AND INDICATIONS OF SLIGHTLY INCREASED PORE PRESSURE NO INCREASE IN OIL OR CUT WERE EXPERIENCED, AND NO VISIBLE CUT WAS SEEN IN THIS INTERVAL, POSSIBLY INDICATING A CONDENSATE OIL OR GAS CAP SHOW. -5- HUE SHALE SECTION (K!0, KS, HRZ) LITHOLOGY THE HUE SHALE CONTAINING THE K-10, K-5, AND HRZ WAS ENCOUNTERED AT APPROX- IMATELY 8284' TVD (8414' MD) AND CONTINUED TO 8460' TVD (8610' MD). IT CONSISTED FIRST OF THE K-10 ZONE, WHICH WAS FROM APPROXIMATELY 8284' TO 8424' TVD (8414'- 8560' MD). THE K-10 WAS PREDOMINANTLY A MEDIUM GRAY BROWN CARBONACEOUS SILTY SHALE, WITH ABUNDANT BLUE GRAY AND WHITE VOLCANIC TUFFS. MINOR SANDY SILTSTONE AND SANDY SHALE INTERVALS WERE ALSO OBSERVED. HINOR INOCER~US PRISMS AND PYRITE WERE ALSO PRESENT, NO INOCERAMUS PRISM FLOODS WERE ENCOUNTERED. THE K-5 AND HRZ WAS ENCOUNTERED AT APPROXIMATELY 8424' TVD (8560' MD), AND CONTINUED TO 8460' TVD (8610' MD). THE HRZ WAS CHARACTERIZED BY VERY FISSILE DARK GRAY SHALES (PAPER SHALE) WITH MINOR SILTSTONE INTERVALS NEAR ITS BASE. BOTH THE K-10 AND HRZ ARE VERY ORGANIC RICH SHALES WITH COMMON ' CARBONACEOUS SPECKS OR L:&~INAE. TRACES OF PYRITE WERE PRESENT. THE K-10 AND HRZ ARE DISTINCTIVE MARKERS FOR CORRELATING THE DISTANCE TO THE TOP OF THE KUPARUK SANDSTONE (PRIMARY OBJECTIVE). ALTHOUGH CUTTINGS SAMPLES ARE SOMEWHAT DISTINCTIVE, A MORE EXACT METHOD FOR DETERMINING THE TOPS OF THE K-10 AND HRZ IS BY USING THE MWD GAMMA RAY. DRILL RATE AND GAS DATA THE DRILL RATES RANGED FROM 25 TO 125 FEET PER HOUR IN THIS HOLE SECTION. THE AVERAGE DRILL RATE WAS 50 FEET PER HOUR. DITCH GAS RANGED FROM 20 TO 1250 UNITS, AND AVERAGED 75 UNITS. C1 THROUGH C4 WERE PRESENT THROUGHOUT THIS INTERVAL. AN INCREASE IN THE HEAVIER (C3+) GASES CAN BE ATTRIBUTED TO THE HIGH ORGANIC CONTENT OF THESE SHALES AND ALSO TO THEIR OVERLYING PROXIMITY TO THE OIL-BEARING KUPARUK SANDSTONE. HIGH CUTT!NGS/BLENDOR GAS WAS ALSO DETECTED (15 - 110 UNITS), SUBSTANTIATING THE HIGH ORGANIC CONTENT, YET LOW PERMEABILITY, OF THESE SHALES. OiL AND GAS SHOWS DULL GOLD S.&~PLE FLUORESCENCE AND MILKY YELLOW SOLVENT CUT WERE OBSERVED THROUGHOUT THIS INTERVAL. ABUNDANT BLUE MINERAL FLUORESCENCE ASSOCIATED WITH THE VOLCANIC TUFFS WAS ALSO VERY DISTINCTIVE. A SHOW RATING OF POOR WAS GIVEN THE INTERVAL DUE TO THE POOR PERMEABLILITY AND RESERVOIR CHARACTER OF THE ROCK (I.E. SHALE). -6- KALUBIK AND KUPARUK SECTION LITHOLOGY THE KUPARAK WAS DRILLED AT ABOUT 8470 FEET TVD (8622' MD). THE 9 5/8" CASING WAS SET IN THE HRZ FORMATION, SO THAT CORING OF THE FORMATION CONTACT BETWEEN THE KALUBIK AND KUPARUK COULD BE ACHIEVED. THE KUPARUK SANDS (PRIMARY OBJECTIVE) WERE ENCOUNTERED APPROXIMATELY 12 FEET INTO THE FIRST CORE (8470' TVD, 8622' biD). CUTTINGS S.~IPLES OF THE KUPARUK SANDSTONE DURING INITIAL STAGES OF CORING WERE POOR. HOWEVER, CLOSE INSPECTION SHOWED THE SANDSTONE TO BE FINE TO HEDIUM GRAINED BECOMING FINE TO VERY FINE GRAINED WITH DEPTH. THE SANDS WERE GENERALLY CLEAR TO OPAQUE , WITH OCCASIONAL BROWN OIL STAINED, SUB-ROUNDED QUARTZ WITH SLIGHT TRACES OF GLAUCONITE. SORTING WAS MODERATE TO VERY WELL SORTED. SAND GRAINS WERE UNCONSOLIDATED IN CUTTINGS SAMPLE, EXCEPT AT THE BASE OF THE KUPARUK WHERE SIDERITE CEMENTATION WAS OBSERVED. DARK GRAY SHALE AND SILTSTONE WAS PRESENT IN VARYING AMOUNTS WITHIN THE KUPARUK, PRESUMABLY AS INTERBEDS IN THE SAXDSTONE. VISIBLE POROSITY IN THE SANDSTONE WAS GENERALLY VERY GOOD (I.E. UNCONSOLIDATED). IN THE 8640' TO 8740' SAMPLES, RED IRON STAINING WAS OBSERVED WITH PROBABLE ASSOCIATED SIDERITE. DRILL AND GAS DATA MOST OF THE SECTION wAS CORED, WITH AN 8-1/2" CORING ASSEMBLY. TWO CORES WERE TAKEN FROM 8460 FEET TO 8598 FEET TVD (8610'- 8757' MD). CORING RATES RANGED FROM I TO 70 FEET PER HOUR, AVERAGING 30 FEET PER HOUR. CORE RATES WERE HIGHEST IN THE UPPER PORTION OF THE KUPARUK, AND AVERAGED NEARLY 60 FEET PER HOUR IN THESE ZONES. DRILLING ABOVE AND BELOW THE CORED INTERVAL AVERAGED 30 FEET PER HOUR. GAS READINGS RANGED FROM 3 TO 985 UN[TS, AND ALSO COINCIDED With ANY DRILLING BREAKS. THE AVERAGE GAS READINGS DURING THE FASTEST CORING INTERVAL WERE 300 UNITS. C1 THROUGH C4 WERE PRESENT THROUGHOUT MUCIt OF THE INTERVAL. WITH C4 DROPPING TO ZERO IN AREAS OF LOWER TOTAL GAS READINGS. OIL AND GAS SHOWS A WATERBASED BLAND CORING FLUID WAS USED AFTER THE 9 5/8" CASING. WITH THE EXCEPTION OF A 985 UNIT GAS SHOW, THERE WERE NO OIL SHOWS IN THE CUTTINGS S.&~IPLES, THEY HAD APPEARED TO BE WELL WASHED OF ANY SHOW IF THERE WAS ONE TO START WITH. NO SHOW REPORT WAS WRITTEN FOR THIS INTERVAL. -7- MILUVEACH SECTION LITHOLOGY THE TOP OF THE MILUVEACH WAS ENCOUNTERED AT APPROXIMATELY 8580' TVD (8738' MD). CUTTINGS SAMPLES CONTAINED PROGRESSIVELY HIGHER PERCENTAGES OF DARK GRAY-BLACK AND DARK BROWN SUB-FISSILE SHALE OR MUDSTONE. MINOR MEDIUM GRAY SILTSTONE WAS ALSO PRESENT. THE WELL PLAN CALLED FOR DRILLING 100 FEET OF THE MILUVEACH, IN ORDER THAT SUFFICIENT "RAT HOLE" WOULD BE PRESENT FOR ELECTRIC LOG AND PRODUCTION LINER RUNS. THE WELL WAS TD'D IN THE MILUVEACH AT 8677' TVD (8840' ~D), DRILL AND GAS DATA THE DRILL RATES IN THIS SECTION WERE FAIRLY CONSISTENT. RATES RANGED FROM 10 TO 35 FEET PER HOUR, WITH AN AVERAGE OF 20 FEET PER HOUR. GAS READINGS IN THIS SECTION WERE LOW AVERAGING 5 UNITS. C1 THROUGH C3 WAS PRESENT THROUGHOUT MUCH OF THIS SECTION. OIL AND GAS SHOWS OIL SHOWS GRADUALLY DECREASED IN THIS HOLE SECTION. PRESUMABLY, ANY FREE OIL AND STAINING WERE A RESULT OF THE OVERLYING KUPARUR SANDS. -8- APPENDIX I.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. David W.
