Open hole window milling not to exceed 15'. 10-407 TS 12/31/25 01/06/26 To: Alaska Oil & Gas Conservation Commission From: Trevor Hyatt Drilling Engineer Date: December 29, 2025 Re:03-18A Sundry Request Sundry approval is requested to set a whipstock in the 03-18A wellbore as part of the drilling and completion of the proposed 03-18B CTD lateral. Proposed plan: Prior to drilling activities, screening will be conducted to drift for whipstock, caliper and MIT. E-line will set a 4- 1/2"x7" whipstock. Coil will mill window pre-rig. If unable to set the whipstock or mill the window pre-rig, the rig will perform that work. See 03-18B PTD request for complete drilling details - A coil tubing drilling sidetrack will be drilled with the Nabors CDR2 or CDR3 rig. The rig will move in, test BOPE and kill the well. If unable to pre-rig, the rig will set the 4-1/2"x7" whipstock and mill a single string 3.80" window + 10' of formation. The well will kick off drilling in the Shublik and lands in the Ivishak. The lateral will continue in the Ivishak to TD. The proposed sidetrack will be completed with a 3-1/2"x3-1/4"x2-7/8 13Cr solid liner, cemented in place and selectively perforated post rig (will be perforated with rig if unable to post rig). This completion will completely isolate and abandon the parent Prudhoe Pool perfs. 20 AAC 25.112(i) Variance Request: Hilcorp requests to plug the existing perforations via the liner cement job and/or liner top packer, if the liner lap pressure test fails as an alternate plug placement. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current wellbore and proposed sidetrack is attached for reference.

Drill build section: 4.25" OH, ~410' (35 deg DLS planned). 4. Drill production lateral: 4.25" OH, ~2,371' (12 deg DLS planned). Swap to KWF for liner. 5. Run 3-1/2 x 3-1/4 x 2-7/8 13Cr solid liner 6. Pump primary cement job*: 74 bbls, 15.3 ppg Class G, 1.24 (ft3/sk), TOC at TOL. Set LTP*. If high losses are encountered during cement job and it is deemed necessary, a cement down squeeze from TOL to loss zone will be performed with the rig or service coil (if performed by service coil see future sundry). 7. Only if not able to do with service coil extended perf post rig Perforate Liner with 1-1/4" CS Hydril 8. Freeze protect well to a min 2,200' TVD. 9.

It appears that the packer information has not been updated following the workover completed in early March 2008. The new production packer at 8630' and and the new liner top packer at 3977' and have not been included. It is appropriate to send in a revised 404. Where there is a liner top packer, it is probably appropriate to add "finer top". Call or message with any questions. You do not need to send the attachments.

We hope to integrate whatever reports Milne has been submitting into our current systems. We'll check in with you and Winton in January to see what sort of report modifications you may need. Anna and I changeout today, have a nice holidays.

Was the 1900 psi in IA applied for an MIT? Well should be added to monthly injector rpt. Thanks. Jim Regg AOGCC NSU, ADW Well Integrity Engineer wrote: Hello Jim & Winton.

All wireline work will be done through a 5000 psi WP BOP/Lubricator, tested to 1.2 times the maximum expected surface pressure. The SSSV will be installed at the conclusion of the perforating and clean-up operation. The well is currently injecting produced water. Produced water will be in the wellbore during perforating operations. These perforations are in the Zulu waterflood zone. The reservoir pressure at the perforation depths is approximately 3600 psi.

The permit to redrill 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. The blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035; and the mechanical integrity (MI) of the injection wells must be demonstrated under 20 AAC 25.412 and 20 25.030(g)(3). Sufficient notice (approximately 24 hours) of the MI test before operation, and 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 tests. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Chairma~~_~ '.

A sidetracked replacement welibore with new tubulars will reestablish MI injection and remedy the profile problems. The scope of the project is as follows: · Permanently abandon current wellbore and remove existing tubing which leaks on MI. · Drill replacement wellbore. · Obtain Iow invasion conventional core of the lvishak formation. · Obtain openhole logs to correlate to core measurements. · Complete well with isolation packer/taiipipe between Zulu and Victor and L-80 tubing. · Restore MI injection to pattern, support pattern Zulu offtake with injection, and reduce Victor overinjection. The cores will provide quantitative Sorm and "tongue thickness"/sweep efficiency data describing the WAG process. The data will serve to reduce the WAG process uncertainties.

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, select samples as prescribed in the instructions. 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. The cores, 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 fit the core together, oriented the core with the apparent up dip at the top, and marked depth and orientation. Sample intervals were marked on the core at the wellsiteo A four 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. Once the samples were designated and sawed the entire core was wrapped in saran wrap and aluminum foil and dipped in Core Seal. The core was then placed in boxes which 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 tn 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" samples selected at the wellsite were depreserved. 1.5 inch horizontal and vertical plugs were drilled with brine. 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. Samples found to be pebbly sand or conglomerate were processed as whole core sections. The remaining whole core was then rewrapped in Saran Wrap and foil and dipped in CoreSeal. ' Following the completion of Dean-Stark extraction of the "SC" samples ARCO personnel chose additional sample sites to complete the data set. The sampling completed, the core was depreserved 10 feet at a time, oriented with the top of the bedding up, and slabbed 1/3 and 2/3. Samples designated by ARCO for long term studies were not depreserved. The 2/3 sections were washed with fresh water and allowed to dry for photography. A more complete description of the core processing procedures can be found in the appendix. Core Photographs Approximately 15 feet of the cleaned 2/3 slabbed sections appears in each photograph. Eight sets of visible spectrum flash and eight 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. Plug ends were placed in plastic bags. The procedures are detailed in the appendix. .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 two days. Vertical plugs were extracted in the same Dean-Stark equipment and toluene as the horizontal plug from the same foot. The Toluene remaining in the Dean Stark flasks was recovered for chemical analysis. Plugs were removed from the water Dean-Starks and placed in cleaning Dean-Stark units containing chloroform cleaning solution. Cleaning continued until the cleaning solution showed no crude oil color after eight hours. Whole core samples were cleaned in a C02-toluene extractor at our Anchorage facility. Extracted samples were considered clean when no fluorescence was observed using trichloromethane under an ultraviolet light. Extracted samples were dried in a 180 degrees F. convection oven for a minimum of 8 hours then transfered to a 180 degrees F. vacuum oven for 24 hours and until sample weights were constant to 0.02 grams (plug} or 0.1 grams {whole core) over a four hour drying period. Samples were cooled in a desiccator to room temperature before porosity and bulk volume were measured. After the bulk volume was measured the sample ends were recleaned in a sonic cleaner and dried using the same procedure as before to stable weights - 0.05. grams for plugs or 0.2 grams for whole core - before permeability was measured. Dean-Stark Fluid Saturation Measurements and 2. Saturations by Dean-Stark methods were calculated using Equations I 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. Where: Vpc = Vp x £(w2 + Wgl)/W2) 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 (2a) Where: Wgl = Wpb - Wb - W2 Wgl = Weight of Grains Lost During the Process Wpb = Dry, Stable Weight of the Plug plus the ARCO Prescribed Bag and thimble Wb = Weight of Bag and thimble 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. Where: Dg : Mg/Vg Dg = Grain Density Vg = Grain Volume Mg : Grain Mass (3) Atmospheric Porosity The plug samples were measured for bulk volume by mercury displacement at ambient conditions. Whole Core bulk volumes were measured by displacement of water by presaturated samples. Porosity was calculated using Equation 4. P = [(Vb-Vg)/Vb)] x 100 Where. P: Porosity, Percent Vb = Bulk Volume Vg = Grain Volume (4) Atmospheric Permeability to Air Permeabilities of horizontal and vertical plugs 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. Maximum, minimum, and vertical whole core permeabilities were measured in a triaxial type holder at 400 psig. Both plugs and whole core were sonic cleaned and redried before permeabilities were measured..Permeability calculations were performed as defined by Darcy's Equation for compressible fluids, Equation 5 was used to determine permeabilities. Pa x v x 1000 I(: .................... x (P] - P2)(PI +P2) QaxLxL Vb (5) Where.

These cores will provide core gamma-ray log, at-the- sudace residual oil saturation, porosity, grain density horizontal permeability, vertical permeability and lithology. Residual oil composition will provide information on miscible gas sweep efficiency. GENERAL GUIDELINES I . This procedure is for coting, core handling and laboratory core analysis. Core Laboratories must be able to mark, lay-out, cut core barrels and preserve on- site. Laboratory sampling and routine core analysis will be conducted in Anchorage. Materials/supplies on-site than might be more than initially estimated due to preservation of many small pieces. 3. All cores will involve the following: a. Core preservation (Saran wrap and aluminum foil on-site). b. Core Diameter- 4-inches Inner Barrels - Aluminum, 30-foot, 60-foot d. Low invasion core bits and codng procedures e. Expedited core processing 4. Well site personnel requirements from Core Lab will be 4. Materials that Core Labs must be able to supply on coring jobs are listed below. 5. The well site operations will be minimized and conducted quickly so the core may be transported to the commercial lab in Anchorage for routine analysis. The summary of operations Is: At Rig Site A. Cut a window at 7617" ss in the existing 9 5/8" casing. As soon as feasible, change over the window cutting mud to a bland coring fluid. Drill into the top of zone 4 in the Sadlerochit with that mud. Condition the mud for coring. B. Use iow invasion core bits, codng mud and coring procedures, 60-foot aluminum . inner barrel, 4-inch core diameter, KCl waterbase mud with bromide tracer to core the Sadlerochit. C. Depth mark, double stripe and cut inner barrel into 3-foot lengths in the pipe shed. Cap the 3-foot inner barrel sections. Move the inner barrel sections to the core trailer for marking, sample sawing and preservation. Routine whole core samples will be 4" long. D. Transfer the core to Anchorage by air freight as soon as possible. E. Notify commercial lab to be at freight terminal in Anchorage. In Anchorage F. Commercial lab personnel will pick up the core and immediately begin core processing. G. Conduct core gamma ray log. H. Cut 1.5" diameter routine horizontal and vertical plugs from the uninvaded core center and trim off invaded ends of the horizontal plug. Whole core analysis will be conducted in the conglomerate and pebbly intervals whore plugs cannot be taken. Dean Stark toluene will be saved for crude oil composition analysis, I. Conduct routine core analysis. Depth mark and place the slab from the routine core samples in with the 3/4 butt section after plugging. The routine samples which are whole core will be slabbed later. J. Ship Dean Stark toluene to Piano for crude oil analysis. April 15, 1993 K. After whole core Dean Stark, the samples will be dried, packaged and shipped to Midland, Texas for cleaning. Quality control of this operation will be Core Labs Anchorage responsibility. L. Bromide tracer.analysis will be done by Peak Pedormance in Houston. Ddlling mud filtrate and core leaching water samples will be sent directly to Peak Pedormance. M. Select 12 samples from conglomerates or very pebbly sandstones where plugs can not be cut. Select 100 samples from clean sandstones in zones 4 and 2. These intervals will not be slabbed. They will be long term preserved in Plane for later special core analysis. N. Slab the core 1/4 - 3/4. Mount the slab in slab boxes with Styrofoam inserts. Take visible and U. V. light photographs of the slab. O. Conduct long term preservation in Plane on selected samples of 3/4 butt end. CORING OPERATIONS WINDOW CUTTING-Cut the window with the window cutting fluid and drill ahead to establish the new hole. As soon as it is feasible replace the window cutting fluid with codng fluid. Clean the pits and mix the coring mud. Drill to a 5-foot drilling break at the top of the Sadlerochit, condition the mud. The hole bottom should be free of drill cuttings and other debris before coming out of the hole to pick up a core barrel the first time. A junk basket should be run to remove metal from the bottom of the hole which may damage the large cutter core bits. CORING MUD- The coring mud should be similar to the mud which has been successfully used at Point Mclntyre and other locations where there are reactive shales within and above the formation of interest. This mud consists of 8 Ib/bbl pre-hydrated bentonite, 1.51b/bbl Drispac Superlo, 18.0 Ib/bbl potassium chloride, 1.0 Ib/bbl sodium bromide, 57 Ib/bbl calcium carbonate (Baracarb 5), 0-0.5 Ib/bbl Drispac Regular and 6 Ib/bbl Dextrid (potato starch). Static fluid loss for this mud is about 4cc, with mud weight 10 lb/gal or greater depending on the amount of calcium carbonate. This is a Iow spurt loss mud and this mud will give Iow invasion in high permeability sands such as the Sadlerochit. Ben Bloys has provided a recommendation of the final coring mud formulation. This coring mud composition and properties are critical to obtaining Iow invasion core. CORING EQUIPMENT-A 6 3/4" X 4" core barrel with aluminum inner barrels should be used in coring. Core barrels may be either 30 or 60 feet in length. Longer barrels should not be attempted because of 35° hole angle. Either slip type or split ring catcher may be used. Orientation scribes and a core orientation survey can be run in zone 4 only. Jamming will be increased if scribes are run in the conglomerate intervals and zone 2. Many catcher shoes have scribe knives in them even when a core orientation survey will not be conducted. These should be removed if orientation will not be done. Aluminum inner barrels are recommended rather than fiberglass because of greater mechanical strength particularly at the bottom-hole temperatures in the Sadlerochit. The aluminum core barrels are disposable barrels that can be cut up and rubber capped at the well site. The coring equipment vendor will provide tools including a cutting stand and clamp to cut the inner barrel, rubber caps and hose clamps. Pipe cutters rather than a carborundum blade saw is preferred for Safety reasons to cut the inner tube. Inner tube spacing between catcher shoe and bit is very important in Iow invasion coring since this spacing controls the flow of mud in the bit throat and this affects filtrate invasion. About half of the mud flow will go through face discharge ports if the spacing is properly set. Inner barrel bearings will be required at the catcher shoe and at 30 feet due to hole angle exceeding 30°. Several different types of core bits will be required for this operation. Sandstones and pebbly sands in zones 2 & 4 Conglomerates in zones 4A, 3, and 2C 4 ea. RC 412N FD 2ea. SC 713GFD 2ea. SC 712GFD 2 ea. SC 777G FD 2 ea. MC 201 FD April 15, 1993 The RC 412 bit is the Iow invasion core bit and will work well in sands and pebbly sands. It will yield Iow invasion and high codng rates in these intervals. The conglomerate is more of a problem and we may not achieve low invasion there. The MC 201 has been historically used in conglomerate intervals but only cuts at 2 to 3 feet/hr and will not yield Iow invasion. The SC 712 bit will cut conglomerates at a much higher rate, 5 to 15 feet/hr, may give low invasion but will not last long, based on our experience at Point Mclntyre. Hughes Chdstensen will modify this bit to increase the number of cutters and bit life while still maintaining a higher coring rate. The new bit is the SC 713. The other bits are back-ups which we hope will not be needed. CORING PROCEDURES -- Low invasion coring procedures will be used in coring the Sadlerochit. In addition to the core bits and coring mud recommended above, the coring procedures will be modified for Iow invasion. Low invasion is dependably obtained even in high permeability 'rocks at highercoring rates. With the RC 412N FD codng rates as high as 200 feet/hr are possible in clean sands. Low invasion will be achieved in most sands so long as coring rate exceeds 30 to 60 feet/hr. Higher rotary speed, up to 80 rpm and higher bit weights, 6000 to 10000 lb. will produce coring rates which easily reach 120 feet/hr in good quality sandstone. Rotary speed and bit weight needed will depend on rock properties with lower rotary speed and higher bit weight in poorer quality rock. Mud circulation rate should be in the range from 200 to 300 gal/min. In previous Sadlerochit Iow invasion coring with the RC 412N FD at DS 14-39 we found 200 gal/miR to be adequate with coring rates as high as 200 ft/hr. SC 712G FD tended to require a higher mud rate at Point Mclntyre, closer to 300 gal/min to achieve good cuttings removal. Higher clay content and smaller cutters probably contribute to the need for higher mud rate for that bit. Bailing due to poor cuttings removal is a problem with larger cutter bits and this will cause reduced coring rate. Since coring rate has a first order effect on filtrate invasion and mud rate has at most a second or third order effect, mud circulation should always be adequate to remove cuttings at the sustained coring rate. Drill into the Sadlerochit and use the RC412N FD on a 60-foot barrel for the first core. When you are coring conglomerate at the base of zone 4 (coring rate will fall off or coring will cease more than likely with substantial bit damage) change to a 30-foot barrel for stiff bottom hole assembly and the SC 713G FD. If the SC 713G FD cores well then the next core should be a 60 foot barrel. If not, then use the SC 712G FD on the second core and a 30 foot barrel. If neither of these bits work well, use the SC 777G FD next. The last resort is the MC 201 FD. As soon as possible change back to the RC 412N FD below the conglomerate. The SC 712G FD and the SC 713G FD will not yield Iow invasion in the high permeability pebbly sands of zone 2 with a waterbase mud. We need to use the RC 412N FD as much as possible. The coring company representative at the well site should have experience with iow invasion codng. Mike Morgan (Eastman Teleco) is recommended for Anchorage-based operations.

The melting pot will be filled with CoreSeal and turned on. The pot temperature will be adjusted according to the length of time before the core is recovered, place on Iow (180 °F)ff more than 48 hours is anticipated. It is recommended that the melting pot be checked at regular intervals. When . , . April 15, 1993 turned on and never exceed the recommended dipping temperature for Core Seal (320 ° - 330 °F). Sampling equipment will be set up and tested. All personnel will be H2S certified and will need to familiarize themselves with the -areas on the well site lhat 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,-'l:~'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. ' ARCO will provide two core processing trailers. Trailer1 will be used for core layout, depth marking, sampling and preservation of whole core. Trailer 2 will be used for core storage and geologic description. Trailer 2 should have a working melting pot for CoreSeal as a back-Up for Trailer 11' -" ' Upon completion ot the above preparations, the core boxes should be put together and marked with client name, well name, core number, and box number. Samples o! 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 quart, collected in a nalgene container with screw cap. The label on the bottle 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 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 ~ark inner barrel.' Double stripe red and black, red on right looking up-hole. Mark depths each foot on outer barrel starting from core top and cut inner barrel into 3-foot lengths. Place rubber caps on each end of core with hose clamps to hold caps in place. Load inner barrel sections on fork lift and transport to core trailer for layout. Place core sections in of the core trailer. Core Lay-Out The core should be laid out on the counter in 5- or 10-foot lengths by a Service Company Lab representative. Dump core out of inner barrel sections onto lay-out bench. '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 (4" X 4") are marked every foot starting at the foot marker and extending four inches below the marker. If this location is not suitable for plugging the sample top may be moved up to 4.0 inches above the foot marker or down up to 2 inches below 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. Routine whole core samples are preserved separately for ready identification once they reach Anchorage.. ............. Core Preservation The core is placed with the top to the left on the bench in the core trailer. 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 sudace which will not damage Saran and foil. Wrapping should begin as soon as POssible' following SCF sample identification and separation. The core April 15, 1993 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 white stick-on labels and 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 hunq 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. Once all the core has been preserved and placed in the open core boxes, it should be 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 depths are then placed on the core boxes and the boxes are packed and sealed for shipment. 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 codng 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 and mud samples. 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 ANALYSIS IN THE ANCHORAGE LABORATORY 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 plugging 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. Cut the plugs immediately upon arrival at the service laboratory regardless of the time of day. The service company personnel will be notified when the core leaves the airport 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 three 60-foot cores in a single. 24-hour period. The main objective is to obtain true sudace oil saturation and oil composition with consistent analytical techniques. The horizontal and vertical core plugs from a given foot will be analyzed for water in the same Dean Stark device with no change in toluene. Record and remove water when each plug is complete. After vertical plug Dean Stark, save the toluene in the same type boule as used for Point Mclntyre core analysis and ship the toluene to Piano for compositional analysis. Exposure to air should be minimized to avoid evaporation of fluids and wettability changes. Bromide tracer will be used to identify those routine core plugs and whole core that have significant mud filtrate invasion. Bromide will remain in the routine plug or whole core after Dean Stark. A decision will be made on which plugs or whole core should be analyzed for bromide after the routine analysis is complete. April 15, 1993 . All routine plug drilling will be done with nitrogen driven, synthetic reservoir bdne which is used only once to remove cuttings. . 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. 7. Chips will be taken for the State of Alaska at the time of core plugging. o Calibrations will be pedormed on all balances using standard weights at least once before every core. Weights used should approximate sample weights. . Core will be 1/4 slabbed after routine analysis is complete, estimated to require 2 weeks. Approximately 12 preserved conglomerate or pebbly sandstone intervals and 100 clean sandstone samples, 8 inches long will be excluded from slabbing. 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. 12. The 1/4 slab will become a library sample and should be double striped, depth marked, placed in a slab box and returned to Anchorage. 13. Some samples will be long term preserved in Piano for later testing. Shelf life for such samples is up to 5 years. 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 essential to the calculation of filtrate saturation in the cores. Therefore, it must be collected and analyzed for bromide concentration. Core Laboratories can filter these mud samples with an APl filter press. This filter press should be cleaned with soapy water and rinsed thoroughly with distilled water before filtering the next sample. This will take about I 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. This sample is sent to the lab for tracer analysis by ion chromatography. The lab for bromide analysis will be Peak Performance, Houston, Texas, (713) 485-8655. Surface Core Gamma Log The core is laid out on tables in depth order while still preserved. 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 Horizontal and vertical core plugs will be cut once each foot from sands which are not too pebbly. If a plug can not be obtained then conduct whole core analysis. Look for yellow and white double stripe on top of the core, rotate core 90° and dry saw a 1-inch slab from the whole core. Double stripe the 1 -inch slab and mark depth. Preserve the slab with the routine whole core remnant after plUgging is complete. This slab will be placed in depth sequence when the entire core is slabbed. Cut the 1.5-inch diameter horizontal routine plugs parallel to bedding plane with synthetic reservoir brine used once. The plug will be cut from April 15, 1993 the butt portion starting at this saw-cut face. The diagram below illustrates the slab and horizontal plug locations. ROUTINE CORE SAMPLE 1.5" X 1.5" HORIZ m m m m I I PLUG II 1.5" X LS" mm mm mm mm mm mm mm mm SLABBED FAC~ 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, U necessary, with a brine moistened cloth to remove excess brine immediately after plugging. SC SAMPLE ~--~2 7/8" --~ 1.25" le5I! ,,51 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 end piece so that the resulting plug is 1.5 inches long. Identify plug number . on the core plug and end piece. Preserve plug in Saran wrap (6 layers) and aluminum foil (3 layers). Relabel with plug number on the foil. Place wrapped plug in pre-weighed bottle, seal, tape and weigh. Label the bottles with well name, depth, plug number, tare and total weight. Store the plug at 50 °F in .l April 15, 1993 refrigerator until Dean Stark analysis. Wrap end piece in Saran wrap, tape closed, heat seal in PmteCore laminate and mark depth and plug number on the package. Indicate end piece with EP following plug number. The figure above shows the plug and trimmed end. Whole core samples should remain preserved until they can begin Dean Stark analysis. The SCF 3/4 butt end should be preserved in Saran, aluminum foil and CoreSeal if the drilling of the vertical plug is not to be conducted immediately. Vertical Core Plugs The routine vertical core plugs will be cut once every foot following the cutting the horizontal plug. These will be 1.5 inch diameter by 1.5 inches long cut perpendicular to bedding (approximate hole angle is 35°) from the same whole core SCF sample used to obtain the horizontal core plug. Prepare a core ii(] to IX)IH __ the whole core at the correct angle for Dlugging. This core plug should be cut from-the exact core center or as close thereto as possible using synthetic reservoir brine. First trim the sawed end of the plug and then trim off the end piece so that the resulting plug is 1.5 inches long. Identify plug number on the core plug and end piece. Preserve plug in Saran wrap (6 layers) and aluminum foil (3 layers). Relabel with plug number on the foil. Label the bottles with well name, depth, and plug number. Store the plug at 50 °F in refrigerator. Place end piece in bags labeled with plug number and depth for possible geological use. The analysis of this core plug will follow the same procedure as the horizontal core plug. Dean Stark analysis will be conducted in the same Dean Stark eqUipment as the horizontal plug from that depth. When the horizontal plug analysis is complete, remove the water. Pour the toluene in the side arm back into the pot, dry the side arm and then conduct a vertical plug Dean Stark in the same manner as the horizontal plug. When the vertical plug Dean Stark analysis is complete, pour the toluene from the side arm into the pot, and save all the toluene for later analysis. Dean Stark Analysis The Dean Stark method is used to determine water saturation. Dean Stark sidearm should be 10 cc capacity. Core Lab will Drovide a cost estimate for the eauiDment urmrade. The flasks and glassware must be cleaned from the previous use to insure there is no residual Water. Rinse condenser, core chamber and flask five times with 20cc of fresh toluene and discard the rinses. Weigh a clean, dry Dean Stark flask. Add 120/:1 cc of pre-boiled toluene. Weigh flask and toluene. To keep toluene loss to a minimum, keep the system closed except when adding or removing sample. The core plug or whole core sample is removed from its preservation materials. The core plug is weighed to an accuracy of t-0.001 g (plug) or +.01 g (whole core), placed in a pre-dried and pre-labeled bag to trap lost grains and re-weighed to the same precision. If core plugs are soft or poorly consolidated in some intervals, then encase them in Teflon tape, lead foil and screens prior to the last weight. Obtain individual weights on Teflon, foil, and screens. wt= W+Wf+Ws+Wc Total weight of core, t-0.001 Weight of teflon, :!: 0.001g Weight of lead foil, t-0.001g Weight of screen, t-0.001g Weight of fresh core, +0.001g The plug or whole core is then loaded into the Dean Stark apparatus without further delay. Then, seal the apparatus. Perform all tasks for one plug or whole core at a time. Use shrinkable Teflon for the whole core samples which tend to break apart. Obtain comparable weights. to those above 'at a precision of t-0.01g for the whole core. Toluene is refluxed until no further change in the water volume in the receiver is'observed for four hours.' Take readings at 8, 12, and 24 hours. Use first stable reading to calculate water saturation. Continue with April 15, 1993 daily readings if necessary. 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 ~'olume of the water to within :L-0.025CC (plugs) or :L-0.2 CC (whole core), or about 1.0% PV. if water volume 'is less tha~t 0.5 CC, Pull water from receiver with a syringe and weigh it. Extract with toluene for at least 2 days in the Dean Stark. Our intent is to extract as much cnJde oil as possible with the toluene to give a reliable composition for the crude. Conduct Dean Stark analysis of the vertical core plug from this same depth in the same' Dean Stark extractor using the same procedure as for the horizontal core plug. Use the same'toluori6'~i~~'~-~-d~l--f6~- ....... · ...... the horizontal core plug extraction. Pour the toluene from the sidearm back into the still pot after remev~ .- ' the horizontal plug water. Dry the side arm and then conduct the vertical plug Dean Stark. ' Longer times may be required for whole core samples, allow for 4 days in the' Dean: Stark'for purposes of ........ the cost quotation. The procedure for the whole core Dean Stark will be the same as the horizontal core plug with the exceptions on weight and water volume precision noted above. Thimbles are not needed for the whole cores, they will be encased in double thickness indiviual bags for Dean Stark extraction and cleaning. 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 storage 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 core number, core depth and plug number. These samples will then be shipped in one core lots (approximately 60 feet) to ARCO · Exploration and Production Technology. The packaging will be according to DOT regulations. Plug and Whole Core Extraction Remove the horizontal plug. Remove plug from its bag. Place the plug on top of the bag=in a pre-dried,' pre-labeled and pre-weighed thimble. Place plug thimble and bag in a second Dean Stark device for extraction with chloroform. Replace the chloroform with fresh solvent after the first forty-eight hours.; then, replace it every twenty-four hours. Continue extraction until clean chloroform shows no cnJde oil color after eight hours. A clean core plug should not fluoresce when trichloromethane is dropped on' 'it iJnder ultraviolet light. Extraction time should be a minimum of two days and may require .as 10rig as~'~'~/~i~l{~ not use batch cleaning techniques in this step. · .-' ':..' ..'. .;.;: ....... .. ~; ::.~. ;:..:.; The vertical core plug will be cleaned using the same procedure as the horizontal core plug. Core Lab, Achorage will be responsible for the quality of the whole core cleaning.operations .in. Midland Texas. If cores are returned incompletely cleaned then Anchorage will see to it that they are cleaned. The cores will remain in a double thickness individual bag. Dry the whole cores in a convection oven over- nite to remove the toluene. Dry the core to constant weight, +.1 grams. Preserve the core in its bag 'as it' was preserved at the well site to prevent breakage. Ship the cores to Midland,.Texas for cleaning. Use wooden shipping boxes and package the cores so breakage will not occur:..When...the cores arrives, in Midland, Texas each core should be weighed again after depreservation. Core Lab, Anchorage will ship standard weights, 500 and 1000 grams, to permit a comparison of the two balances.` ' ~ ' --" ~''. ~:*-" '-. Conduct CO=,-toluene extraction in Midland. The procedure will be that described in the Procedure transmitted to us by facsimile by Perry Brown, FebnJary 22, 1993. The samples will be*remain indouble thickness individual bags with a fine mesh to prevent grain loss. If grain loss occurs, the oil volume in the core becomes unknown and' we consider this to be an extremely important nUmber. Monitor the core tubes daily..If grain loss;Is Observed, .cease cleaning until a suitable container for the core can be obtained. All cleaning and drying operations will be conducted with the cores in these bags. CO2-toluene extraction should continue until the loluene does not discolor and there is no streaming fluorescence when trichioromethane is placed on ~the core under ultraviolet light. The minimum extraction' time Will be one week. Samples should only be removed after that, if they meet the test for no streaming fluorescence. Use care to prevent grain loss due to mechanical abrasion of the cores when testing flourescence. 10 April 15, 1993 Leave the cores in their double thickness, Individual bags. Dry the whole cores in a convection oven at least 24 hours to remove the toluene. Dry the core to constant weight, +.1 grams. Preserve the.core in its bag as it was preserved at the well site to prevent breakage. Ship the cores to Anchorage, Alaska for drying and porosity measurement. Use wooden shipping boxes and package'the cores so breakage will not occur; · When the cores arrives in Anchorage, Alaska, each core should:be-' weighed'again after depreservation. Plug and Whole Core Drying Dry core plug and thimble or whole core and bag in a convection oven at 180° F for 8 hotJrs':"-'l'l~e'n;-~ry-tt~ core plug and thimble or whole core and bag in a vacuum oven for 24 hours at 1'80°"F and then to constant weight +0.02 grams (plug) or .1 grams (whole core), after four hours additional drying.' Cool the plug and thimble or whole core and bag over desiccant. Weigh the plug and thimble Within t-0.001 g or whole core and bag t-0.01 g. Remove plug from thimble or whole core from bag. Brush dry plug or whole core to remove fines and weigh again The procedure for whole core sample drying is the same as the above procedure for plugs, except as noted. Time required for whole core extraction and drying will be longer than for plugs 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 saturation. The helium porosimeter will be used to determine the grain volume of all samples. Samples from drying are kept over desiccant until ready for grain volume measurement, ff the samples are exposed to laboratory air for more than 30 minutes, they should be redded and re-weighed. The helium porosimeter should be recalibrated to t-0.1% twice a day. The porosimeter should be checked with a steel cylinder with a known volume to t-0.1% after every five samples and after a break in::instrurneht* usage of greate-t.. ' than one hour. If drift between successive calibrations will cause graindensity.t0 vary ~*0~i005.~g~cc, calibrate before every sample. Bulk volume of the plugs will be measured by mercury immersion. Bulk volume will be measured within t-O.01 cc (t-0.05% BV). Maximum depth of immersion in mercury will be the minimum required to yield an accurate bulk volume. The plugs 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 bf"42 Cc approximate bulk volume) will be significant intrusion. Bulk volume will be increased, to correct for the calculated mercury intrusion. Bulk volume of the whole cores will be measured by the Archimedies method using water. First, immerse the sample until it stops imbibing. Weigh the sample in air and immersed in Water. Weight precision will be :/0.01 grams. Permeability to Air Permeability to air is measured on all routine horizontal and vertical core plugs. 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 ovemight in a vacuum oven at 180 °F. Plugs will be weighed to a stable weight t-0:05'g. 'Whole cores should be cleaned to remove mud cake and saw cuffings in the same way. Drying'should be to t-0.2 g for whole core. Then proceed with measurement of permeability. 11 April 15, 1993 Permeability is measured with 400 psi net overburden pressure. Complete recalibration of permeameter will be pedormed 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. Two horizontal and a vertical permeability will be measured on the Whole core. A maximum permeability- and permeability at 90° to that direction will be measured in the horizontal direction. - Tracer Analysis Bromidetracer will be measured iby procedures provided in appendix '1: Leach-waterwilfbeshippedlor ............... analysis by ion chromatography to Peak Performance. Houston, Texas, (713)-'485-2854. CoTe-Lab-'wili--be responsible for calculating and reporting bromide concentrations and filtrate saturations,as part .of the routine analysis. The amount of tracer analysis to be conducted will be decided based on oil saturation levels in the core. Tracer analysis could be none or a significant fraction of the sandstone and pebbly sandstone intervals. This core offsets a waterflood injector and tracer analysis will only be done if there are high oil saturations in some intervals. Core Slabbing. Core slabbing may be conducted when routine core analysis data are complete. AAI will select approximately 12 preserved whole core samples which will not be slabbed. These 12 samples will be divided into 4 similar samples having mostly larger cobbles, 4 similar samples with pebbles and 4 similar samples which are pebbly sandstones. These should all be samples which would not be suitable for plug type.,analysis. ,,The, core will be depmserved..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<' from these markings and cut the slab..The,white,. and yellow markings are on the up dip 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:.expesum:...The* preservation procedure used will be identical to the initial preserVation in. the:'fleld:...six:...~ayers o~mran_wrap/ three layers of aluminum foil, and two dips of Core Seal. The routine core .analysis. samplewas slabbedat the time of plugging. The slab will be placed in slab boxes with Styrofoam inserts without any spacers between the, sections after slabbing. Keep these slab boxes covered with the lids. . Photograph the slab in colored and ultraviolet light. , . · . 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, and relative permeability. 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 nbt be' adequate for some lab tests ......... . Some 3/4 butt sections and whole core may be preserved for a longer term in an nitrogen purged, heat- sealed envelope of ProteCore containing formaldehyde as a bactericide, surrounded by paraffin wax in a large metal can crimp-sealed while the paraffin is liquid so as to totally exclude air from the can. Shelf life for such samples is expected to be about 5 years. Rich Treinen will provide details of this procedure and costs. 12 April 15.'

In addition, the existing injection profile is compromised by a straddle packer between the Zulu and Victor intervals that was inadvertently set within Victor perforations during a 1986 rig workover. A sidetracked replacement wellbore with new tubulars will reestablish MI injection and remedy the profile problems. The scope of the project is as follows- · Permanently abandon current wellbore and remove existing tubing which leaks on MI. · Drill replacement wellbore. · Obtain Iow invasion conventional core of the Ivishak formation. · Obtain openhole logs to correlate to core measurements. · Complete well with isolation packer/tailpipe between Zulu and Victor and L-80 tubing. · Restore MI injection to pattern, support pattern Zulu offtake with injection, and reduce Victor overinjection. The cores will provide quantitative Sorm and "tongue thickness"/sweep efficiency data describing the WAG process.
