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.

History of P2 -51. In late April 2006, P2 -51 was shut in due to high water cut and has not been on production since. Well P2 -51 was drilled and completed in mid 1994. The well was completed with perforation intervals in the UC4 /UC2 -3 /UC1 and the UB1 -2. Production struggled until late 1995 when the well was fractured with 68K pounds of proppant. Production jumped to 5 times the production pre frac and stabilized around 3 times the production prior to the frac. This frac job is the best performing frac of the 15 or so jobs pumped at PM. Water broke through towards the end of 1997 and both oil production and GFR began serious declines. In July of 1998 a coil clean to 13,195' was performed. A static pressure of 4,350 psi was observed in May 2001. The UC 2 -3 /UC1 was re- perforated in May 2002 but the production impact is not obvious. A static pressure was taken on 10/29/04 that observed 4392 psi. The most recent calliper from 11/11/11 showed no significant wall penetrations or areas of cross - sectional wall loss were recorded. All sidetrack screening pressure tests passed. Reason for sidetrack. P2 -51 is no longer a competitive producer due to high water cut and has no remaining well work options. The proposed sidetrack will access two separate drainage targets, lateral A to West and lateral ALI to the North. Proposed plan for P2 -51A & AL1 is to mill the XN nipple, set a whipstock and squeeze cement into the existing perforations pre -rig. The sidetrack P2 -51A, will exit the existing 7" liner with a 4 -1/4" open hole and kick off in the Kuparuk UC2 and land in the Kuparuk UB1 -2. A 3 -1/4" intermediate liner will be run and cemented in place covering the whipstock by 102'. The purpose of the 528' intermediate hole is to isolate the water cut parent P2 -51. The shoe track will be drilled out and a 3'open hole will be drilled to 14,514', and completed with a slotted liner. Then a whipstock will be set at 13,320' and the P2 -51AL1 lateral will be drilled to 15,558' and completed with a slotted liner. The following describes the work planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. do JU ced T 4 we « w'j ([0 ell C%elf le» ( kV 1 �fi ( Oitev(. (A/441k (ai qqt y „o�t� Cvj .

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 P2-51 well from the North Slope, Alaska. Presented herein are the results of this study. Conventional cores cut with an oil 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 plots 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 these data prove beneficial in the development of this reservoir. Section 1 2 3 4 TABLE OF CONTENTS CONVENTIONAL CORE ANALYSIS, SERVICE DESCRIPTION CONVENTIONAL CORE ANALYSIS, TABULAR RESULTS CONVENTIONAL CORE ANALYSIS, STATISTICAL AND CORE GAMMA DATA APPENDIX 5 DATA DISKETTE SECTION 1 CONVENTIONAL CORE ANALYSIS SERVICE DESCRIPTION SECTION 1 CONVENTIONAL CORE Fi el d Procedures Conventional coring equipment in conjunction with a oil based drilling fluid was used to extract core samples during July of 1992. All cores were taken using aluminum inner core barrels. Five 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, assited 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 1 through 6, which were contained in aluminum inner core barrels, were taken to the pipe shed, depth marked and double striped, and cut into three foot sections with tubing cutters. The ends of the sections were then rubber capped and clamped. These sections were then taken to the core trailer. Upon arrival of the core at the core trailer a Core Lab representative fit the core together, oriented the core with the apparent up dip at the top, and marked. Sample intervals were marked on the core at the wellsite. Each had a two letter designation which was marked on the core and later on the foil wrapping. 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 sample site was allowed within one inch of a fracture in the core. 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 whic were marked, taped, and stacked 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 samples selected at the wellsite were depreserved and 1.5 inch horizontal plugs were drilled with hexadecane. To provide complete core data for later reservoir studies, additional plugs were taken from intervals which were not designated at the wellsite. The plugs and were immediately loaded into the Dean-Stark apparatuses or, if no Dean Stark units were available for immediate use, preserved for minimum exposure and placed in jars. The remaining whole core was rewrapped. The sampling completed, the core was depreserved 10 feet at a time, and slabbed 1/4 and 3/4. The 3/4 slabbed sections were immediately represerved with Saran Wrap, foil, and Core Seal. The 1/4 sections were washed with fresh water and allowed to dry for viewing and photography. A more complete description of the core processing procedures can be found in the appendix. Core Photographs The core was oriented with the top of the bedding at the top of the core and slabbed 1/4-3/4. Approximately 15 feet of the cleaned 1/4 slabbed sections appears in each photograph. 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. Plug ends were placed in plastic bags. The procedures are detailed in the appendix. 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 oil mud and chosen solvents, placing marks on the plugs and end pieces would be impractical and/or potentially damaging to the analysis. Foil was labeled for plugs waiting to be loaded into the Dean Stark units. Once unwrapped, the sample thimbles were marked and separate labels were placed with the samples from station-to-station until the samples were dry. At that point, numbering was applied to the sample. Original: Refers to the chloroform-methanol cleaning equipment as Dean Stark 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. PERMEABILITY TO AIR, page 15 Original: Calls for samples to reach stable weight as described after cleaning. Change: A weight was recorded. Dean-Stark Fluid Saturation Measurements Water was extracted from the samples by Dean-Stark technique using toluene in cleaned apparatuses. Fresh commercial grade toluene was used for each extraction and the equipment was cleaned between each sample as directed by Arco. Extraction continued until no change in water volume was observed over a four hour period. Minimum extraction time was twelve hours. All spent toluene was recovered for chemical analysis. Samples were removed from the water Dean-Starks and placed in cleaning Dean Stark units until the 87 volume% chloroform - 13 vol% methanol cleaning solution showed no crude oil color after eight hours. Extracted samples were dried in a 180 degrees F. vacuum oven for a minimum of 24 hours and until sample weights were constant to 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 or displacement at ambient conditions. Porosity was calculated using Equation 4. P: [(Vb-Vg) / Vb)] x 100 (4) Where: P: Porosity, Percent Vb: Bulk Volume Vg : Grain Volume Atmospheric Permeability to Air Horizontal permeabilities were measured in a Hassler type core holder at a confining pressure of 400 psig after the plugs were cleaned in a sonic cleaner and redried. Permeability calculations were performed as defined by Darcy~s Equation for compressible fluids, Equation 5. No permeabilities were measured on the PG ends or Tracer samples. Pa x v x 1000 QaxLxL K - x (5) (P1 - P2)(P1 +P2) Vb Where- K = Permeability v = Gas Viscosity P1 - P2 = Differential Pressure = Mean Pressure Pa = Atmospheric Pressure Qa = Flow Rate L = Length Vb : Bulk Volume P1 + P2 Mud Filtrate In Core Tracer concentration in plug samples was calculated using tracer concentrations supplied by CPM Laboratories. Filtrate saturations were calculated using Equation 6. Sof = 100*(Wo*Ff/O.82)/Vp (6) Where- Sof = Saturation of Filtrate in Core (% pore volume) Wo : Weight of Oil Phase in the Core Ff : Weight Fraction of Filtrate in the Oil in the Core Vp = Pore Volume of the Core (cc's) Pluqqing Fluid Saturation Hexadecane saturations as a percent of pore volume was calculated using data provided by CPM Laboratories in Equation 7. Soh = (Wto*Cht)/(ph*Vp) (7) Where: Soh = Hexadecane saturation in % of pore volume Wto = Weight, in grams, of toluene after the Dean Stark procedure. ph : The density of hexadecane, .777 gm/cc Vp : Pore volume in cubic centimeters Corrected Oil Satuaration An oil saturation adjusted mud filtrate and hexadecane invasion using CPM Laboratories~ data was determined using Equation 8. Where: So corr : (So-Somf-Soh) So corr = Corrected oil satuartion in % of pore volume So : Uncorrected oil satuaration Somf = Mud filtrate in core (Equation 6) Soh : Hexadecane saturation (Equation 7) (8) ~ompany ~ell · .

INTEGRATED FORMATION LOG (MD), INTEGRATED FORMATION LOG (TVD), DRILLING DATA LOG, AND PRESSURE DATA LOG INTRODUCTION THE P2-5I WELL IS ONE OF A SERIES OF POINT MCINTYRE DELINEATION WELLS, DRILLED ON THE WEST DOCK PAD, APPROXIMATELY 12 MILES NORTH WEST OF PRUDHOE BAY, ALASKA. COORDINATES FOR THE SURFACE LOCATION OF THE WELL ARE: 509' FNL & 1250' FWL, iN SECTION 14, T12N, R14E UMIAT MERIDIAN. PROPOSED BOTTOM HOLE COORDINATES WERE TO THE NORTH AT: 2410' FNL & 209' FEL, IN SECTION 3, T12N, R14E UM. THE MAIN OBJECTIVE OF THIS WELL WAS TO TEST THE KUPARUK RIVER FORMATION, A LOWER CRETACEOUS AGE MEMBER OF THE UGNURAVIK GROUP, AT A PROJECTED DEPTH OF 8912' 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: 2592' FSL & 163' FEL, IN SECTION 3, T12N, R14E UM. THE PROPOSED TARGET WAS REACHED BY DRILLING A DEVIATED HOLE; THROUGH THE USE OF DIRECTIONAL DRILLING TOOLS AND TECHNIQUES. SUCH THAT THE PROPOSED BOTTOM HOLE LOCATION WOULD BE NORTH AT AN AZIMUTH OF 350.42 DEGREES AND WITH A DEPARTURE OF 8782', WITH RESPECT TO SURFACE LOCATION. PROGNOSED BOTTOM HOLE COORDINATES WERE: 2410' FNL & 209' FEL, IN SECTION 3, T12N, R14E THE WELL PROGRAM WAS DESIGNED FOR THE KICK-OFF TO START AT ABOUT 500' MD AND TO GRADUALLY BUILD ANGLE TO 55.2 DEGREES FROM TRUE VERTICAL AT ABOUT 4009' MEASURED DEPTH. iT WAS PROPOSED TO HOLD THE HOLE ANGLE WAS BUILT TO A MAXIMUM OF 5?.? DEGREES AT 903? FEET. THE ANGLE WAS THEN MADE TO DROP TO 24.? DEGREES AT 13426 FEET. THE WELL PROGRAM WAS DESIGNED TO SET 9-5/8 INCH CASING JUST ABOVE THE TOP OF THE KUPARUK AND TO CHANGE OUT THE FRESH WATER BASED DRILLING MUD TO LVT 200, A MINERAL OIL BASED DRILLING FLUID WITH LESS THAN 2% WATER CONTENT, DESIGNED FOR THE RETRIEVAL OF LOW INVASION CORES. THE PROJECTED STRATIGRAPHIC SEQUENCE PENETRATED BY THIS HOLE INCLUDED THE PERMAFROST, T-3, K-15, WEST SAK, K-10, HRZ, KALUBIK, AND KUPARUK RIVER FORMATIONS WITH PROPOSED FINAL WELL T.D.

THE SYSTEM IS A COMPUTER BASED DATA COLLECTION UNIT, USED IN ACQUiSITiON, COMPILATION AND OUTPUT OF DATA. ADDITIONAL LITHOLOGIC AND HYDROCARBON EVALUATION WAS PROVIDED BY EXLOG'S ONSITE GEOLOGISTS. METHODS OF ANALYSIS USED FOR EVALUATION ARE PRESENTED IN EXLOG'S MANUAL "MUDLOGGING: PRINCIPLES AND iNTERPRETATIONS" (MS-t96). MUDLOG THE MUDLOG FORMAT WAS PREVIOUSLY ESTABLISHED ON FORMER POINT MACINTYRE WELLS LOGGED BY THIS CREW. DATA DISPLAYED ON THE LOG INCLUDES: LITHOLOGY, RATE OF PENETRATION, TOTAL GAS, CUTTINGS GAS, CHROMATOGRAPH DATA, RESISTIVITY AND GAMMA RAY DATA WAS IMPORTED FROM TELECO AT THE END OF EACH BIT RUN. TOTAL GAS, RATE OF PENETRATION, CUTTINGS GAS AND GAMMA RAY ARE PLOTTED LINEARLY, WHILE ALL OTHER PARAMETERS ARE PLOTTED LOGARITHMICALLY. LOGS WERE PLOTTED AS 2 INCHES PER 100 FEET (1:600), WITH THE EXCEPTION OF THE PRESSURE DATA LOG. DRILL DATA DRILLING DATA MONITORED INCLUDED: RATE OF PENETRATION (ROP) USING THE BLOCK HEIGHT SYSTEM, ROTARY SPEED, HOOKLOAD, WEIGHT ON BIT, TORQUE (MINIMUM, MAXIMUM, AND AVERAGE), MUD FLOW IN AND OUT, MUD TEMPERATURE IN AND OUT, STANDPIPE PRESSURE, CASING PRESSURE, 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 FOR THE DISPLAY OF ALL DRILLING PARAMETERS. THERE WAS A RADIO MODEM CONNECTION WITH A REMOTE TERMINAL IN THE DRILLING OFFICE OFF LOCATION IN THE LIVING CAMP, AS WELL AS A REMOTE TERMINAL IN THE GEOLOGIST'S OFFICE AT THE WELLSITE. AN EXPLOSION PROOF DRILL MONITOR (HAD) WAS PROVIDED FOR THE DRILLER ON THE RIG FLOOR. SAMPLING SAMPLES WERE COLLECTED AS PER THE DIRECTIONS RECIEVED FROM BOB DAWSON IN THE ARCO ALASKA OFFICES. THREE WET AND FIVE DRY SAMPLES WERE COLLECTED. 8875' - 12620' MD 12620' - 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 SAMPLE SHIPMENTS CAN BE FOUND IN THE APPENDIX. -3- FORMATION EVALUATION LOGGING COMMENCED AT 2300 HOURS, JULY 3, 1992 AT 6380 FEET TVD (8875 FEET MD) IN THE LATE CRETACEOUS. ALL DEPTHS, UNLESS OTHERWISE SPECIFIED, ARE REFERENCED FROM THE KELLY BUSHING WHICH WAS 46 FEET ABOVE SEA LEVEL. ALL FORMATION TOPS ARE UNCONFIRMED AND APPROXIMATE, AND BASED ON CUTTINGS EVALUATION. WEST SAK INTERVAL LITHOLOGY THE WEST SAK 6960' - 8805' TVD (9940 - 12740' MD) SAND INTERBEDDED WITH SILTSTONE WITH MINOR CLAYSTONE AND THIN COAL iS THE DOMINANT LITHOLOGY TO A DEPTH OF ABOUT 7350" TVD. THE SANDS ARE GENERALLY VERY FINE TO FINE GRAINED QUARTZ WITH COMMON SILT AND CLAY MATRIX. FROM ABOUT 7350' TVD, (10625' MD) TO 8805' TVD (12740' MD), THE LITHOLOGY CONSISTED ALMOST EXCLUSIVELY OF SILTSTONE GRADING TO SHALE WITH MINOR SAND INTERBEDS. THE MEDIUM GRAY AND GRAY-BROWN COLOR OF SILTSTONE CHANGED TO A DARK GRAY AND GRAY BROWN SILTY SHALE NEAR THE BOTTOM OF THE INTERVAL. ABUNDANT INNOCERAMUS PRISMS OCCURRED FROM 7230'TVD (10400'MD) TO 7250' TVD (10440' MI)). AGAIN AS IN THE P2-50 WELL, THIS ABUNDANCE OF INCERAMUS PRISMS OCCURS AT A SHALLOWER DEPTH THAN EXPECTED. ALSO PRESENT WERE BRACHIOPOD FOSSILS AT A DEPTH OF 7250 'FO 7270' TVD (10440 TO 10475' MD). -4- DRILL RATE AND'GAS DATA THE DRILL RATES RANGED FROM 2 TO 220 FEET PER HOUR THROUGH THIS HOLE SECTION. IT AVERAGED 80 FEET PER HOUR TO 10000' MD WHERE IT DROPPED TO AN AVERAGE OF 30 FEET PER HOUR. DITCH GAS RANGED FROM 5 TO 125 UNITS IN THIS SECTION, AND AVERAGED 30 UNITS. HIGHER GAS READINGS OCCURED AT THE TOP OF THIS SECTION, DROPPING AT 10500 FEET MEASURED DEPTH TO AN AVERAGE OF 15 UNITS. Cl THROUGH C4 WAS PRESENT THROUGHOUT MUCH OF THE SECTION, WITH OCCASIONAL ABSENCE OF C4 IN THE MIDDLE TO LOWER PORTIONS OF THE SECTION. OIL AND GAS SHOWS ONE LONG, YET INTERMITTENT TRACE OIL SHOW CHARACTERIZED THE WEST SAK SANDS IN P2-51. THERE WAS LITTLE VARIATION if 7HE OIL SHOW AND MAY BE DESCRIBED AS HAVING FROM 5% TO 45% DULL GOLD SAMPLE FLUORESCENCE, A WEAK GREEN TO YELLOW SLOW CUT FLUORESCENCE, NO VISIBLE CUT, AND NO RESIDUAL RING AFTER EVAPORATION OF THE CUTTING AGENT. OCCASSIONALLY A SLIGHTLY STRONGER TRACE SHOW WAS ENCOUNTERED WITH A PALE YELLOW STREAMING CUT FLUORESCENCE AND A LIGHT STRAW TO STRAW VISIBLE CUT AND A LIGHT BROWN RESIDUAL RING. THE RATING GIVEN THE SHOW WAS VERY l~OOR TO POOR (SEE APPENDIX FOR SHOW REPORT #1). -5, HUE SHALE SECTION (K10, HRZ) LITHOLOGY THE HUE SHALE CONTAINING THE K-10 AND HRZ WAS FIRST ENCOUNTERED COMMENCED AT APPROXIMATELY 880§' TVD (12740' MD) AND CONTINUED TO 8900' TVD (12846' MD). IT CONSISTED FIRST OF THE K-10 ZONE, WHICH WAS PROBABLY 10 OR LESS FEET THICK. THE K-5 AND K-2 WERE ABSENT, AND ONLY ABOUT 25 FEET OF HRZ WAS PRESENT. POOR CUTTINGS QUALITY WERE PRESENT THROUGHOUT THIS THIN SECTION. THE HRZ, BEING SO THIN, WAS ONLY DETECTED AFTER CIRCULATING BOTTOMS UP AFTER A SHORT TRIP. THE CUTTING S~d~PLES CONSISTED OF MEDIUM TO DARK GRAY SILTSTONE AND SHALE. A TRACE TO 30% SANDSTONE, AND TRACES OF PYRITE AND TUFF WERE ALSO PRESENT. TRACE AMOUNTS OF INOCERAMUS PRISMS WERE ALSO OBSERVEDIN THIS SECTION. THE SECTION EXHIBITTED GOOD SOLVENT CUT AND FAINT FLUORESCENCE AS THE HUE SHALE IS CONSIDERED TO BE A MAJOR SOURCE ROCK FOR THE NORTH SLOPE AREA. DRILL RATE AND GAS DATA THE DRILL RATES RANGED FROM 30 TO 90 FEET PER HOUR IN THIS HOLE SECTION. THE AVERAGE DRILL RATE WAS 40 FEET PER HOUR. DITCH GAS RANGED FROM 20 TO 75 UNITS, AND AVERAGED 30 UNITS. C1 THROUGH C4 WERE PRESENT THROUGHOUT THIS INTERVAL. OIL AND GAS SHOWS DULL GOLD SAMPLE FLUORESCENCE AND YELLOW SOLVENT CUT FLUORESCENCE WERE OBSERVED THROUGHOUT THIS INTERVAL. A SHOW RATING OF POOR WAS GIVEN THE INTERVAL DUE TO THE POOR PERMEABLILITY AND RESERVOIR QUALITIES OF THE ROCK (I.E. SHALE). -6- KALUBIK AND KUPARUK SECTION LITHOLOGY THE BOTTOM OF THE HUE SHALE (THE BOTTOM OF THE HRZ SPECIFICALLY) AND CONVERSELY THE TOP OF THE KUPARUK (KALUBIK?) WAS ENCOUNTERED IN CORE #2 AT A DEPTH OF 8841' TVD (15381' MD). THE CUTTING SAMPLES WERE HIGHLY CONTAMINATED BY CEMENT CUTTINGS FROM 15338' TO 15390' MD. FOLLOWING THE DISAPPEARANCE OF CEMENT AS AN IMPEDIMENT TO VISUAL IDENTIFACATION, FURTHER DIFFICULTY WAS ENCOUNTERED. SHALE AND SILTSTONE FROM THE FORMATION BETWEEN THE 9 5/8" CASING SHOE AND THE TOP OF THE KUPARUK (KALUBIK?), MASKED THE CUTTINGS. THE DRILLING FLUID USED FOR CORING {LVT200 VERSACORE) ALSO MASKED THE SHOWS AND SAMPLE. AS WELL AS THE AMOUNT OF CUTTINGS PRODUCED BY THE CORE BITS, WHICH WAS MINIMAL. THE SAND THAT WAS SEEN IN THIS INTERVAL WAS A VERY FINE TO FINE GRAINED SAND, AND VERY SILTY, OFTEN GRADING TOWARDS A SILTSTONE. THE SORTING WAS POOR TO MODERATE, THERE WAS NO VISUAL POROSITY. BUT FOR THE MOST PART, THE SAMPLES CONSISTED OF SHALES AND SiLTSTONES. DRILL RATE AND GAS DATA THIS ENTIRE SECTION WAS CORED WiTH A 8.5" CORING ASSEMBLY. THE DRILL RATES RANGED FROM 2 TO 54 FEET PER HOUR, AND AVERAGED 15 FEET PER HOUR. THE HOLE ANGLE IN THIS HOLE SECTION WAS HELD AT 30.5 TO 32 DEGREES. THE OITCH GAS. IN THIS SECTION WAS 5 TO 50 UNITS. THE AVERAGE DITCH GAS WAS 20 UNITS. C1 THROUGH C4 WAS PRESENT IN THE ENTIRE SECTION. OIL AND GAS SHOWS THERE WAS A SHOW REPORT WAS DONE ON THIS SECTION, BUT THE RESULTS ARE OBSCURED BY THE POOR QUALITY OF CUTTING SAMPLES AND THE USE OF A OIL BASE MUD HINDERS THE EVALUATION OF THE CUTTINGS. THE SHOW WAS GIVEN A POOR RATING DUE TO THE MIXED RESULTS AND THE LACK OF VISUAL POROSITY IN THE SAND THAT WAS ENCOUNTERED. SEE APPENDIX FOR SHOW REPORT #3. -7- MILUVEACH SECTION LITHOLOGY THE TOP OF THE MILUVEACH WAS ENCOUNTERED AT 9368' TVD (13365' MD). THERE WAS A TRANSITION ZONE IN COLOR AND CONSISTENCY OF CUTTINGS BETWEEN THE LOWER KUPARUK AND THE TOP OF THE MILUVEACH. HOWEVER, THE TOP OF THE FORMATION AS DEFINED BY OUR SAMPLE EVALUATION CORRESPONDED WELL WITH THE APPROXIMATE TOP AS DEFINED BY MWD DATA. THE CUTTINGS SAMPLES CONTAINED PROGRESSIVELY HIGHER PERCENTAGES OF GRAY-BROWN AND BROWN BLOCKY MICACEOUS SHALE, TYPICAL OF THE MILUVEACH. ONLY 100 FEET OF THE MILUVEACH WAS PENETRATED, IN ORDER THAT SUFFICIENT "RAT HOLE" WAS PRESENT FOR ELECTRIC LOG AND PRODUCTION LINER RUNS. DRILL AND GAS DATA THE DRILL RATES IN THIS SECTION WERE VERY CONSISTENT. IN THE TOP SECTION, THERE WAS 3 TO 4 FOOT OF SLOWER DRILLING SECTION (UNDER 10 FEET PER HOUR) WHICH MARKED THE BOUNDARY OF THE LOWER KUPARUK AND THE MILUVEACH. AFTER THIS SLOWER INTERVAL, DRILL RATES INCREASED TO AN AVERAGE OF 2§ FEET PER HOUR. GAS READINGS IN THIS SECTION DROPPED TO AN AVERAGE OF 25 UNITS. C1 THROUGH C4 WERE PRESENT THROUGHOUT MUCH OF THIS SECTION. OIL AND GAS SHOWS OIL SHOWS GRADUALLY DECREASED IN THIS HOLE SECTION. PRESUMABLY, ANY FREE OIL'WAS A RESULT OF THE OVERLYING OIL-RICH KUPARUK SANDS. -8- SAMPLE SHIPMENTS FROM P2-51 POINT MACINTYRE WET SAMPLES UNIT 250 AUDI RIG #2 BOX # DEPTHS DATE SHIPPED FLIGHT # SHIPPERS INITIALS W1A W1B W1C W2A W2B W2C 8900-9620 9620-10420 W3A 110420-11320 W3B W3C W4A W4B W4C W5A 11320-12120 12120-12600 7/14/92 7/14/92 7/14/92 7/14/92 5132 7/15/92 WHS 12851-13180 W7C W7B W7A 7/26/92 AK54 7/27/92 W6C W6A 12600-12851 7/14/92 5132 7/15/92 W6B 5132 7/15/92 5132 7/15/92 1 I 5132'7/15/92 WHS WHS WHS WHS WHS WHS W5B W5C 7/14/92 5132 7/15/92 SAMPLE SHIPMENTS ~OM P2-51 POINT MACINTYRE WET SAMPLES UN~I~ 250 AUDI RIG #2 BOX # DEPTHS DATE SHIPPED FLIGHT # SHIPPERS INITIALS W1A W1C W2A 8900-9620 9620-10420 W2B W2C W3A 10420-11320 W3B W3C W4A W4B W4C 11320-12120 W5A 12120-12600 W5B W5C W'6A 12600-12851 W6B W6C WTA 12851-13180 WTB W7C 7/14/92 5132 7/15/92 7/14/92 5132 7/15/92 7/14/92 5132 7/15/92 7/14/92 7/14/92 7/14/92 5132 7/15/92 5132 7/15/92 5132 7/15/92 7/26/92 :AK54 7/27/92 WHS WHS WHS WHS WHS WHS WHS SAMPLE SHIPMENTS FROM P2-5i WET SAJ~PLES POINT MACINTYRE BOX # DEPTHS DATE SHIPPED FLIGHT # SHIPPERS INITIALS W8A 113180-13465 !

COREN~G OBJ'ECTIVES The coring involves mineral oil base cores in 4-13 wells. These cores will provide in-situ water saturation, rock properties and iithology for the use of the Point Mclntyre Working Interest Owners. GENERAL GUIDELINES 1. This procedure is for well site sampling and laboratory core analysis. . Core Laboratories must be able to mark, lay-out, cut core barrels and preserve on-site. They must be able to plug on-site. Laboratory sampling and routine core analysis will be conducted in Anchorage. Tracer will be conducted elsewhere. o 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 o 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 ESTIMATED AMOLINT OF CORING A-1 605 MD FT B-1 250 MD FT C-1 160 MD FT D-1 310 MD FT E-I 150 MD FT A-2 150 MD FT B-2 220 MD FT C-2 160 MD FT D-2 50 MD FT E-2 130 MD FT F-2 211 MD FT G-2 322 MD FT H-2 400 MD FT (Actual 261 ft., cored May, 1992) Core Laboratories should have more materials/supplies on-site than might be initially estimated from estimated footage of coring due to the preservation of many small pieces. 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. . 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. lodonapthalene drilling mud tracer will be used in all wells to quantify filtrate invasion. WELL SITE CORE HANDLING AND SAMPLING Recommended Tools and Materials Quantifies will vary depending on amount of projected individual well cored interval.

Material and Site Preparation Upon arrival at the well site, the required preservation materials will be set up in the core trailer by Core Lab personnel. The melting pot will be filled with Core Seal and turned on. The pot temperature will be adjusted according to the length of time before the core is recovered, Place on low (180 °F)if more than 48 hours is anticipated. It is recommended that the melting pot be checked at regular intervals when turned on and never exceed the recommended dipping temperature for Core Seal (320 o _ 330 °F). The dip pot temperature must be monitored and recorded for each core preserved. All personnel will be H2S certified and will need to familiarize themselves with the areas on the well site that they will be working in while retrieving the core such as the rig floor, pipe shed, and core trailer location. Contractor will provide safety equipment for their own personnel. This includes, but will not be limited to, steel toed boots, safety glasses, hard hats, dust masks, etc. Also, all personnel should be aware of their areas of responsibility in the preservation operation. Two coring trailers will be required for wells with on-site plugging. ARCO will provide trailers. Trailer I will be used for core layout, depth marking, sampling and preservation of whole core. Trailer 2 will be used for core plugging and represervation of plug and endpiece. Routine core plugs cut at the well site will be preserved in Trailer 2. One trailer will be required if all plugging is done in Anchorage. The trailer will be used for core layout, depth marking, sampling and preserving of whole core. Upon completion of the above preparations, the core boxes should be put together and marked with client name, well name, core number, and box number. 3 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 fight 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 . . 6. Below are the procedures which are planned for the quality control wells. These procedures will apply for the first two wells: Conduct coring in the usual manner in order to achieve low invasion. Core bits appropriate to the rock type will be selected for coring. Mud tracer, iodonapthelene, will be used to indicate the level of invasion by the mud filtrate. The core handling for these cores will be the similar to all other cores as specified under Core Handling Procedures detailed below. When the core is laid out and marked at the well site, dry saw a 3-inch full diameter section of core every foot for routine analysis. Mark it with the initials SCF. Immediately preserve all core, including the dry sawed sections, in Saran wrap and aluminum foil as described later in 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. August 3, 1992 Core Handling Procedures Core lay-out will proceed as described under Core Lav-out in Trailer 1 procedures. SCF samples are identified and the core is marked. SCF samples will be'taken eve~ foot. Whole core sections for SCF samples are d~ 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~ 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 Oiisorbent tissue to remove excess oil immediately after plugging. Use a fresh tissue for each plug to avoid tracer August 3,1992 contamination. Trim one end of the core plug with a dry saw so the final plug is 1.5 inches long. If the plugging bit was not perpendicular to the slab face, first trim the slab side of the plug 1/8 inch (the width of the saw blade) and then trim off the endpiece so that the resulting plug is 1.5 inches long. The diagram below shows the trimmed plug. SC SAMPLE 1.25" 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 froTM 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 l-inch slab should be double striped for Orientation. The sample~ and the slab are then returned to Trailer 1 for Core Seal coating and placed in depth sequence with the rest of the core. Remove the wooden block when the sample is replaced in depth sequence. If geological samples are needed and the plug endpiece is still preserved, the slab 'may be used to obtain geological samples' for' thin sections, etc. The plug itself will not be used for geological sampling since it must be saved for possible future remeasurement of permeability or porosity as a part of quality control procedures. Core Preservation The core is placed with the top to the left on the bench in Trailer 1. This will help insure that the proper core orientation is maintained. When moved across to the other bench for Wrapping this orientation is maintained. The wrapping stations must be covered with Oilsorbent tissue to provide a soft surface which will not damage Saran and foil. Wrapping should begin as soon as possible following SC sample identification and separation. The core August 3, 1992 is then wrapped with Saran wrap (6 layers), then wrapped with aluminum foil (3 layers) and marked. Wrapped core will be marked with depth using a black Marks-A-Lot and with red and black (red on right) orientation lines. Glass strapping tape is placed on the foil under the wire to prevent puncture of the foil. Wire is wrapped tightly around the center of the core to facilitate the dipping of the samples in Core Seal. The core should be completely submerged in the dip tank for 1-2 seconds and then hung on the cooling rack. After the Core Seal has cooled (3-5 minutes), the sample should be redipped to insure a proper seal and to help protect the core from damage during shipment. After the second dip, the wire is cut at a point just above the preserved piece and a small amount of Core Seal should be placed over the exposed wire to eliminate a wicking effect. As the core is preserved, the core is then placed in oil absorbent tissue or bubble wrap lined core boxes. Then, the core is checked for proper preservation and markings. Occasionally the Core Seal will be too thick to read the markings. Therefore, if possible, a waterproof marker should be used to mark the appropriate designations on the outside of the sample. The core is placed in the core boxes and the boxes are labeled on the outside with well .name, equity well name core number and box number. Then, the boxes are sealed. A well site inventory shall be completed for each core and the boxes are placed in shipping crates. Core and Mud Sample Transportation to Anchorage Tracer analysis data will be most valid immediately after coring as an indicator of invasion and degrades with time due to diffusion. The transportation of the cores and associated mud samples will be expedited. Immediately upon completing the boxing of the preserved core, the core, mud samples, routine core plugs and endpieces will be transported by airplane to Anchorage. Ice chests and blue ice will be used to transport routine core plugs and endpieces to Anchorage. Place the jars in holes cut in styrofoam to prevent breakage in the ice chests. The service company personnel will meet the flight and pick up the core. Core processing will begin' immediately upon arrival at the laboratory. ROUTINE CORE ANALYSIS There will be a designated representative of the Operating Company who will act as the point of contact for all matters relating to routine core analysis. All communications with the Service Company will 'be through that point of contact. The point of contact will also be notified if other Working Interest Owners wish to observe ongoing analysis operations. The operating company will provide a list of personnel who have access to the slabbed core. General Core Handling Core sampling will be conducted with minimum elapsed time since the core was cut and preserved. Tracer diffusion stops once routine plugs are isolated from the more invaded outer part of the core. Sample the core immediately upon arrival at the service laboratory regardless of the time of day. The service company personnel will be notified when the core leaves Prudhoe Bay and will pick-up the core shipment at the airport once the freight company releases it. The service company can expect to receive up to two 60-foot cores in a single 24-hour period. In straighter holes and good sandstone pay, it may be possible to cut as many as three cores a day. . o The primary objective is to obtain true connate water saturations with consistent analytical techniques. Laboratory procedures and core handling should always be done consistently. Exposure to air should be minimized to avoid evaporation of fluids and wettability changes. August 311992 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 twill 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 $0 ppb. Large concentrations of chloroform may obscure the tracer which is expected to be present in the Dean Stark toluene at less than 1 ppm. Chlorinated solvents must never be used to clean glassware or core drill equipment. Glassware used for chloroform-methanol cleaning must never be used for the Dean Stark. Each new container of toluene must be sampled and analyzed prior to its use. . . The quality control cores are needed to ensure water saturation and tracer distribution are the same in the laboratory as they were at the well site. Well site routine core plugs will be taken once per foot in at least the first two wells. In these wells, a routine horizontal plug and an endpiece will also be cut once every three feet later in the Anchorage lab. These contiguous samples will be analyzed for tracer concentration, porosity and water saturation. Some endpieces will also be analyzed for water saturation and tracer to provide inside and outside sample data. Tables I 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. o . All core will be 1/4 slabbed at a later time. The core will be kept in a preserved state until it is slabbed. Any samples which are depreserved for the purpose of sampling and analysis will be represerved as quickly as possible to prevent loss of fluids from the remnant. After slabbing, the 3/4 butt end will be immediately represerved with minimum exposure. The 1/4 slab will become a library sample and should be double striped and placed in a slab box. Chips will be taken for the State of Alaska at the time of core plugging, if not already taken at the well site. 10. Calibrations will be performed on all balances using standard weights at least once before every core. Weights used should approximate sample weights. Flow Chart of Laboratory Operations A flow chart of laboratory operations is attached. Mud Filtrate Samples There will be two drilling mud samples shipped from the field with each of the cores. One of these will be taken at the start of coring and one will be taken at the end of coring. A sample of the filtrate is needed so that the tracer concentration can be analyzed. This tracer concentration in the filtrate is August 3,1992 essential to the calculation of filtrate concentration in the cores. Therefore, it must be collected and sent with the toluene samples from a given core in order to obtain the filtrate concentration. M.I. Drilling Fluids is providing a high pressure, high temperature filter press to filter these mud samples. Core Laboratories will filter the samples. The filter press should be cleaned with naphtha and dried at 300 °F between samples. Conduct the filtration at 500 psi and 150 °F until 2 cc of filtrate are collected. This will take about 1 hour. Collect filtrate in a 5-10 cc glass container; seal and tape when finished. Identify core number, core depth, well name, and date on the label. Surface Core Gamma Log The core is laid out on tables in depth order. The core remains preserved while it is gamma logged. The core gamma unit is calibrated with a 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 stripe 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 SLABBED FA( 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 fr(~sh 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. Relabei 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 · END ' ROUTINE PIECE IICORE PLUG . Routine Horizontal Core Plugs Quality Control Well If the core is from a quality control well, a routine horizontal core plug and endpiece 1.5 inches in diameter are cut, one per three feet, in the lab immediately below the field sample location in that foot. The SCL section should have been identified and marked at the well site. Depreserve the appropriate whole core sample and cut the 2-inch whole core section with a dry saw. A l-inch slab is 11 August 3, 1992 cut 90° clockwise looking up hole to the double mark. The 1-inch slab is double striped for orientation. All routine horizontal plugs and end pieces must be cut as rapidly as possible and plugging should be completed within 24 hours after the core reaches the surface at the well site. Weigh the plug or end piece, and preservation materials. Preserve the whole core sample in Saran wrap and aluminum foil before it is moved to core plugging. Place Saran wrap between slab and butt portion; then, wrap them together. The cutting of the Anchorage core plug and endpiece in a quality control well will be exactly as described above except that a 2-inch long core segment is used rather than a 3-inch long whole core segment. The core plug is cut through the center of the 2-inch core segment. No vertical core plugs will ever be needed from these samples. Routine core plugs will also be cut at the well site in quality control wells. These will be transported from Prudhoe Bay in ice chests with blue ice to maintain low temperature and prevent loss of water from the plug. Routine core plugs cut at the well site will be taken immediately to the Dean Stark station for analysis. If a Dean Stark apparatus is not available, the plugs should be maintained at 50 °F until analysis can be performed.. Both wellsite and Anchorage lab routine core plug endpieces will be analyzed once every 6 feet in quality control wells. Endpiece analysis will always be done on immediately adjacent samples from the wellsite and the Anchorage lab. The analysis procedure for the endpiece will be the same as for routine core plugs except air permeability will not be determined. ~All Other Cores If the well isnot designated qualitY control, the routine core plugs will be Cut onceevery' f0°t."Whole 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 lost 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. 12 The Dean Stark method is used to determine water saturation. The tracer in the core will be removed in the Dean Stark extraction and ,,,,,ill 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 analvzed 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% 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 13 August 3, 1992 sets of water determination equipment, 80 plugs could be generated for cleaning per day. Since the probable cycle time for cleaning is 2 to 4 days, we need 320 sets of equipment for chloroform-methanol extraction. The timing for cleaning is hardest to predict, since Iow permeability plugs will undoubtedly require more time. 400 separate pieces of Dean Stark glassware are required. This will permit a completion time for Dean Stark and cleaning of approximately 7 to 9 days for a 4 core well. The tracer analysis lab will finish up in about 9 days, or I 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 d~ys 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 davs to core, 2 days to log, 1 day to skid the rig. For wells that require more than 4 cores, the time for c~ompletion 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 i.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 14 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 August 3, 1992 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. 15 August 3, 1992 Core Slabbing Core slabbing may be conducted when the schedule permits and when the Operating Company representative decides. The core will be depreserved 10 feet at a time. The core pieces will be fit together so that the same side of the core is always presented in the slab. The core will be slabbed 1/4- 3/4 so that the bedding and dip angle are clearly observable. The 3/4 slab should retain the white and yellow stripe and depth markings made at the ,,,.,ell site. Rotate the core 90° clockwise looking up hole from these markings and cut the slab. The white and yellow markings are on the updip side of the core. Plugs cut from 3/4 section on the slab side will be parallel to bedding. Slabbing should be conducted using cooled nitrogen to cool the saw blade. Double stripe the 1-inch slab for orientation. The 3/4 butt end of the core will be immediately represerved in order to minimize exposure. The preservation procedure used will be identical to the initial preservation in the field: six layers of Saran wrap, three layers of aluminium foil, and two dips of Core Seal. The routine core analysis sample was slabbed at the time of plugging. This slab should be placed in a slab box in styrofoam inserts to prevent breakage and in depth sequence with the rest of the slab. The routine core analysis 3/4 section should remain preserved. This section could be used to obtain a vertical core plug adjacent to the horizontal plug for permeability measurement. Preservation of the core will make it easier to extract the crude oil since the sample will not be dried out. The slab will be placed in slab boxes with styrofoam inserts after slabbing. Future Uses of the Preserved Core The 3/4 butt end of the core which has been preserved will provide a future source of core for formation damage, vertical permeability, chloride measurements, relative permeability, etc. It is not known at this time how much of these data can 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. 16 August 3,1992 Table 1 Sample Identification SCF SCL SCFEP SCLEP Field routine horizontal core plug, 1 1/2"x 1 1/2" Laboratory routine horizontal plug I 1/2" x 1 1/2" End piece of field routine horizontal plug, 1 1/2" x 1" End piece of laboratory routine horizontal plug, 1 1/2" x 1" 17 · , ' August 3,1992 Table 2 Sampling and Analysis Frequency *** Sample SCF SCL SCFEP SCLEP Sample Sample Data Data Location Freq Type Freq Turnaround Field 1/IT o,S,T l/FT 2 Weeks Lab 1/3FT* o,S,T 1/3FT 2 Weeks Field 1/FI' o,S,T 1/6FT 2 Weeks Lab 1/3FT* e~,S,T 1/6FT** 2 Weeks In later wells field samples may not be taken and lab sample frequency will increase to one per foot.

Scope: The purpose of this procedure is to provide accurate quantification of drilling mud and cutting fluid in Point Mclntyre core. To accomplish this, a halogenated tracer (1-iodonaphthalene) is added to the drilling fluid at a concentration of ~30 ppm and a "pure" component (hexadecane) is used as a cutting fluid. Each core sample is extracted with approximately 125 mi of reagent grade toluene. The subsequent core extracts are analyzed by gas chromatography (GC) utilizing an electron capture detector (ECD) and a Flame Ionization Dector (FID). The degree of core invasion by the drilling mud is based on the concentration of tracer contained in the toluene extract and the pore'.volume of the extracted core plug. In a similar fashion, the cutting fluid (hexadecane) invasion is based on the concentration of the hexadecane in the toluene extract. !nstru mentation~H~clware (1) (2) (3) (4) (5) (6) (7) (8) HP-5880A Gas Chromatograph~Level 4 HP Model 7364 Autosampler HP Model 19312 Nickel 63 Electron Capture Detector PE/Nelson 25 m X .53 mm ID---0.5 m Film #N931-2689 · : : :..~ .: Valco Three port Valve High Temp Valco 1/16" 304 ss Tee ' HP Auto Sampler Vials and Caps 1 mi Glass Disposable Pipettes or Equivalent Eppendorf Pipettes Reagent5 (1) (2) (3) (4) (5) (6) (7) 1-1odonaphthalene; Eastman Part #2256 Reagent Grade Toluene 1-lododecane; Aldrich Part i#23,825 -2 2 ppm lododecane and 1.0 %1Squaiane in Toluene Standards of l-lodonaphthaiene i0.02 ppm t° 2.0 ppm) in Toluene and Crude Oil (20:1) Point Mclntyre Crude Oil Squalane; Aldrich Part #23,431 - i 20 August 3,1992 GC---Conditiom Oven Profile Initial Temp Initial Time Program Rate Final Temp Detector and Injector Detector Temp Injector Temp Detector Attenuation Injection Volume; Gas Flows Column Flow Nitrogen Makeup Splitter Flow Septum Purge 75© C 2.00 min. 20°/min. 300© C = 325© C = 300© C = 28 = 5.0 gl =. 9.5 cc/min. = 100 cc/min. = 50 cc/min. = 3.5 cc/min. Analytical Procedure (1). Upon receipt each .sample bottle is weighed-to the nearest tenth of:a gram.. and recorded in.'a sampte' log book. The samples will be refrigerated at all times when not being processed. . , . (2a) A 0.5 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) In the case of the concentrated drilling fluid solutions it will be necessary to predilute them ~0.4 g of sample to 10.00 gm with reagent toluene. Actual weights are recorded to the nearest milligram along with the respective dilution factor. (3) 5.0 gl of the sample/internal standard blend is injected into the GC splitter via the auto sampler and data acquisition is initialized. (4) After the internal standard, and tracer have eluted the three-port'vaive 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 August 3,1992 (9) 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.

There are no significant assumptions in the calculations except that recovery of the tracer is quantitativeiand :no losses when cutting plugs. Tests conducted with Point tM. hClntyre core used for damage testing_in_d_i..cate ~acer recovery from the core is quantitative. 99.6% of. _e tracer was recovered by the Dean Stark procedure. Please note: The tracer could show up in the s~de arm and could also be found in the toluene in the core. The retained'toluene volume' in the core is usually a small fraction of the total toluene so that is not a significant error. 24 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 1~ gives the oil satUration corrected for mud filtrate and plugging fluid in the core. This value will be printed out with the routine core data. So con' = So - $of - Soh (10) Core Labs should provide a spread sheet of all weights measured in the core analysis.

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.

McIntyre No. P2-51 well. ) Conservation Order No. 296 ARCO Alaska Inc. Pt. McIntyre No. P2-51 April 3, 1992 IT APPEARING THAT: I · 2o ARCO Alaska, Inc. submitted an application dated February 13, 1992 requesting an exception to 20 AAC 25.055(a)(3) to allow drilling the ARCO Pt. McIntyre No. P2-51 well closer than 500. feet to a quarter section line. Notice of hearing was published in the Anchorage Daily NeWs and the Anchorage Times on March 7, 1992 pursuant to 20 ACC 25.540. . The bottomhole location requested in the original application was incorrect. 0 A corrected application was submitted March 12, 1992. A corrected notice of hearing was published in the Anchorage Daily News and the Anchorage Times on March 14, 1992 pursuant to 20 ACC 25.540 and in the Alaska Administrative Journal on March 23, 1992. e One protest to the original application was received March 18, 1992. . The Commission, by letter dated March 19, 1992 informed the protester of the correction to the application and requested additional information should the protester still wish to protest. 8. No further protests were received. Conservation Ore. April 3, 1992 Page 2 FINDINGS- No. 296 . The ARCO Pt. McIntyre No. P2-51 well as proposed will be directionally drilled from a surface location 509 feet from the north line (FNL), 1250 feet from the west line (FWL) of Section 14, T12N, R14E, Umiat Meridian to a bottomhole location 2410 feet FNL, 209 feet FEL, Section 3, T12N, R14E, Urniat Meridian. Offset operators/owners Exxon Corporation, BP Exploration (Alaska) Inc., and Amerada Hess Corporation have been duly notified. , An exception to 20 AAC 25.055(a)(3) is necessary to allow drilling of the well. CONCLUSION: Granting a spacing exception to allow drilling of the ARCO Pt. McIntyre No. P2-51 well as proposed will not result in waste nor jeopardize correlative rights. NOW, THEREFORE IT IS ORDERED: ARCO Alaska, Inc.'s application for an exception to 20 AAC 25.055 for the purpose of drilling the Pt. McIntyre No. P2-51 well is approved as proposed.
