The rotary sidewalls were preserved in sidewall glass jars. Core Processing Sample Preparation Dean-Stark Sidewall Samples 29 samples were selected for Dean-Stark analysis. They were first cleaned of drilling mud and cut dry into shapes approximating right cylinders. The samples were then weighed, placed in thimbles, and loaded into the Dean Stark. Analysis Techniques Dean-Stark Fluid Saturation Measurements Water was extracted from the sidewall samples by Dean-Stark technique using toluene. Samples were left in Dean-Stark for 24 hours. Recovered waters were measured and the samples were placed in hot toluene for a minimun of 48 hours to extract the remaining hydrocarbons. Extracted samples were dried in a convection oven at 220 degrees F. for a minimum of 24 hours, and cooled in a desiccator to room temperature before porosity and permeability were measured.

Boyle Alaska Oil & Gas Conservation Commission 3001 Porcupine Dr. Anchorage, AK 99501 Dear Mr. Boyle: The following explanation is offered in regards to your concern over dry cuttings sample size for samples collected at ARCO Rock Flour #1, APl# 50-029-22121-00. Much of the well was drilled with a bottom hole assembly using a relatively new technology involving a high speed turbine and specialized bit which tends to pulverize the rock, especially shales. Consequently, the volume of cuttings is much smaller than drilling with a conventional tri- cone bit. The mudloggers on the well made us aware of the small sample volume, but there was little we could do about the problem. We had our mudloggers collect four equal sized sample sets. We have already utilized our sample set and found it small, but representative and adequate for a variety of analyses. It appears that this drilling turbine and bit system will be used more commonly in the future because it enables much faster drilling, lower costs, and a smaller volume of sample material of which to be disposed. We will continue to encourage sample catchers to collect the largest possible cuttings sample. Let me know if you have any questions. Richard A.

The flange studs were hammered up and the unit retested satisfactorily. As noted on the attached AO~C BOPE inspection report, the blind rams could not be tested to 5,000 psi. I authorized this due to the lack of a crossover connection from the gray clamp to chik san at the kill line. This crossover is not a common item and had to be ordered. Without this connection, the maximum mud pump pressure that could be generated against the blind rams was 3500 psi. In summary: I witnessed the BOPE test at AAI's HSU Rock Flour No. 1 well. With the exception of a choke manifold, flange leak, and the lack of a proper cross over connection for the kill line, which resulted in not being able to apply test pump pressure against the blind rams, the test was successful. 02-00lA (Rev. 6/89) 20/ll/MEMO1.PM3 STATE OF ALASKA ALASKA OIL AND GAS CONSERVATION COMMISSION BOPE Inspection Report OPERATION: Drlg, p-'/ Wkvr__ Operator, TEST: Initial Representative Permit # Well sign Rig Location: Sec Drlg contrctr Location (general) Housekeeping (general Reserve pit Rig# MUD SYSTEMS: Visual Audio Trip tank Pit gauge Flow monitor Gas detectors BOPE STACK: Annular preventer Pipe rams ' Blind rams ~ Choke line valve~ HCR valve p.j/,~ Kill line valves Test Pressure l~, Check valve Week 1 y,__ Other /~'Y~# Casing set @ ~ /0 /4 Rep ~-, ~' ~_~/-/~O/X~ ACCUMULATOR SYST~: :' ~ ~ Full charge pressure ~~;'~ / Press after closure J)~OO Pump Jncr clos press 200 psig Full charge press attained ~ ft psig psig min ~5 sec min ~ sec psig ~ Controls: Master Reeote ~// Blind switch cover KELLY AND FLOOR SAFETY VALVES: Upper Kelly Lower Kc1 ly Bal I type Inside BOP Choke manifold Number val vas Number flanges Test pressure II Test pressure Test pressure J Test pressure t!

The main offset used to plan the Rock Flour #1 is the ARCO Hemi Springs State #1 (HSS #1) well drilled in 1984. This offset well is located just over 4 miles to the east of the proposed Rock Flour #1 location. Due to the RFT pressure data collected in the HSS #1, AAI is requesting a waiver of the seismic velocity analysis requirement of 20 AAC 25.033 e 1 for over-pressure prediction in exploration wells. It is felt that with the extensive drilling information available to the west of the proposed Rock Flour #1 in the KRU, and with the RFT information from the HSS #1 to the east, no over-pressured zones will be encountered prior to reaching proposed total depth. A confidential copy of the RFT data from the HSS #1 is attached to form 10-401. A confidential formation top prognosis is also included for the subject well. AAI is also requesting an exception to the requirements of order 20 ACC 25.061 (a) concerning shallow hazard siesmic surveys and analysis. Drilling records for the following wells around the proposed Rock Flour #1 location indicate no encounters with shallow gas hazards: HH$ #1 to the East Mobil - Phillips #1 to the North West Sak #5 to the West West Sak #6 to the Northwest No other data is available that suggests that a shallow hazard should be expected. No high resolution seismic surveys have been run in the area. Nonetheless, the surface hole will be drilled with a diverter system and guidelines for diverting flow from an unexpected shallow gas zone will be available to rig supervisors. Due to the exploratory nature of the subject well, AAI is asking that the Commission maintain the information contained in this application as confidential. If there are any questions concerning this application or if additional information is required, please contact Lowell Crane at 265-1544 or me at 263-4962.

Commission Anchorage ARCO Alaska, Inc. Date: Subject: Internal Correspondence February 12, 1991 Geophysical Pressure Prediction Using Sonic Logs verses Seismic Stacking Velocities. From/Location: Telephone: To/Location: M.B. Morgan 265-1508 Lowell Crane ANO 992 ATe 1410 It is my understanding that the State of Alaska will require geopressure prediction at Rock Flour using "geophysical" data if available, e.g. a crossplot of interval transit time verses depth may be needed to interpret possible Iow velocity intervals which may be related to the presence of over-pressured shales. Data available consists of P-wave sonic logs from nearby wells (Hemi Springs St. #1 and West Sak 5,6) as well as seismic stacking velocities taken from paper cop~es of stacked data in the vicinity. Sonic logs offer a direct measurement Of acoustic velocity in the subsurface and, properly acquiredand edited, are not subject to the magnitude of ~maging errors commonly encoun- tered in reflection seismic data, especially in the area of velocity determination. Sonic logs therefore are generally accepted as a measure of "true" geologic interval velocity and, as such, may be integrated to provide average velocities over any depth interval. Conversely, seismic stacking velocities posted at VA locations on the seismic section are not really geologic velocities at all. They are simply numerical values used by seismic data processors during application of normal moveout corrections to the unstacked data. Stack- ~ng velocities may deviate significantly from "real" average velocities by as much as several thousand feet per second. While it is ultimately possible to correct stacking velocities to more closely approximate geologic velocities, much careful interpretation ~s required and, ultimately, the final measure of success is taken from comparison to nearby sonicwell logs whenever available. I therefore recommend that nearby sonic log data be used to prepare the necessary cross- plots. ~- Senior Geophysicrst Special Seismic Analysis MBM cc: J.E. Bennett D.M.

The main offset used to plan the Rock Flour #1 is the ARCO Hemi Springs State #1 (HSS #1) well drilled in 1984. This offSet well is located just over 4 miles to the east of the proposed Rock Flour #1 location. Due to the RFT pressure data collected in the HSS #1, AAI is requesting a waiver of the seismic velocity analysis requirement of 20 AAC L"~,.,,.)25.033 e 1 for over-pressure prediction in exploration wells? It is felt that with the extensive drilling information available to the west of the proposed Rock Flour #1 in the KRU, and with the RFT information from the HSS #1 to the east, no over-Pressured zones will be encountered prior to reaching proposed total depth. A confidential copy of the RFT data from the HSS #1 is attached to form 10-401. A confidential formation top prognosis is also included for the subject well. Due to the exploratory nature of the subject well, AAI is asking that the Commission maintain the information contained in this application as confidential.

McGee Regional Environmental Supervisor Northern Regional Office Alaska Department of Environmental Conservation 1001 Noble Street- Suite 350 Fairbanks, AK 99701 Re: Permit Application foX.Solid Drilling Waste at Exploratory~rillsitC'Ro~k'Flour #1 ' ) Dear Mr. McGee: ARCO Alaska, inc. hereby makes application for a solid waste disposal permit at the proposed exploratory drillsite Rock Flour #1 located some 4 miles east of the Kuparuk River Unit West Sak Pilot Pad as shown on Figure 1-1. Also enclosed are aerial photograPhs of the proposed drillsite. The Rock Flour #1 drillsite will contain only one below grade drilling waste reserve pit as indicated on Figure 4-3, and only drilling wastes (possibly including ash from non-hydrocarbon combustibles) from this exploratory well will be disposed of at this location. It is estimated that up to 30,000 cubic feet of drilling waste may be generated while drilling the well, but no other drilling or domestic waste will be disposed of in this pit. This application provides for burial of the drilling waste at a depth of at least two feet below the active layer or four feet below tundra level, as stipulated by ADEC regulation 18 AAC 60. Recent data obtained from Pipeline State #1 and Pt. Mclntyre #3, exploratory wells whose reserve pits have had at least one full winter season prove that freezeback (i.e., crystal- lization) of the solid waste occurs and is maintained at a depth of less than four feet below tundra. (See Plate #7 of Attachment #7.) Freezeback as the solid waste disposal method was selected in an attempt to minimize environmental and land surface impact and still serve the objectives of searching for and evaluating new hydrocarbon accumulations. By locating the well on an ice pad, the drilling waste can be covered over with native soils capped with organic material for permanent freezeback, fertilized, and reseeded to promote natural tundra growth as early as possible. It is ARCO's intention to service this location by ice road which will melt with the 1990 breakup. ARCO Alaska, inc is a Subsidiary. of AtlanticRichfieldCompany Mr. McGee November 17, 1989 Page 2 Total personnel at the proposed location at any given time during drilling operations is not expected to exceed 60 employees and contractors. There are no residents within two miles of the proposed location and no below-grade fresh water sources exist because of permafrost.

McGee Regional Environmental Supervisor Northern Regional Office Alaska Department of Environmental Conservation 1001 Noble Street- Suite 350 Fairbanks, AK 99701 Re: Permit Application for Disposal of Solid Drilling Waste at Exploratory Drillsite Rock Flour ¢1 Dear Mr. McGee: ARCO Alaska, Inc. hereby makes application for a solid waste disposal permit at the proposed exploratory drillsite Rock Flour ¢1 located some 4 miles east of the Kuparuk River Unit West Sak Pilot Pad as shown, on Figure 1-1. Aisc enclosed are aerial photographs of the proposed drillsite. The Rock Flour ¢1 drillsite will contain only one below grade drilling waste reserve pit as indicated on Figure 4-3, and only drilling wastes (possibly including ash from non-hydrocarbon combustibles) from this exploratory well will be disposed of at this location. It is estimated that up to 30,000 cubic feet of drilling waste may be generated while drilling the well, but no other drilling or domestic waste will be disposed of in this pit. This application provides for burial of the drilling waste at a depth of at least two feet below the active layer or four feet below tundra level, as stipulated by ADEC regulation 18 AAC 60. Recent data obtained from Pipeline State ¢1 and Pt. Mclntyre ¢3, exploratory wells whose reserve pits have had at least one full winter season prove that freezeback (i.e., crystal- lization) of the solid waste occurs and is maintained at a depth of less than four feet below tundra. (See Plate ¢7 of Attachment #7.) Freezeback as the solid waste disposal method was selected in an attempt to minimize environmental and land surface impact and still serve the objectives of searching for and evaluating new hydrocarbon accumulations. By locating the well on an ice pad, the drilling waste can be covered over with native soils capped with organic material for permanent freezeback, fertilized, and reseeded to promote natural tundra growth as early as possible. It is ARCO's intention to service this location by ice road which will melt with the 1990 breakup. ARCO Alaska, mc is a Subsidiary of AtlanticRichfieldCompany ARCO Alaska, Inc. P. O. Box 100360 Anchorage, AK 99510-0360 APPENDIX A PLAN OF OPERATION HEMI SPRINGS UNIT EXPLORATORY WELL ROCK FLOUR #1 Approximately 898' FWL, 1,624' FSL Sec. 4, T10N, R11 E, UM HEMI SPRINGS UNIT ROCK FLOUR #1 · 2. This Plan of Operation describes ice road and ice pad construction and other procedures necessary for drilling the Rock Flour #1 exploratory well located in Section, 4 Township 10N, Range 11E as shown on Exhibit A. ARCO Alaska, Inc. (ARCO) will act as the Operator for the well. All support and services will be supplied out of the KIC, the KRU, or Deadhorse, Alaska. The entire project will be completed between January and April 1990. Existing Roads There are no existing roads at this location. Planned Access Road 1 , ARCO will construct an ice road departing from the existing gravel road and pad system in the KRU as shown on Exhibit A. Also shown is an alternate route that would be used in the event the KRU State #2 (under separate permit) well is also drilled at the same time. This route would minimize the length of ice road that would need to be built and maintained for the two projects. The ice road will be approximately 4-6 in. thick depending upon topography and a minimum of 24 ft wide. The grade will be essentially flat· The ice road system will be maintained by ARCO. Location of Pro.oo~cl W~II Exhibit A shows the relative location of this proposed well site. Well Site Layout The proposed layout of the drill site and the ice drill pad is shown on Exhibit B. A cross-section of the drilling location is shown on Exhibit C. , L,Q~;ation and Type of Water SU.D.DIv Fresh water is needed for ice road and ice pad construction, drilling operations, and camp use. The primary source of water will be from approved lake sources in the Kuparuk area. Water may be hauled from additional approved sources but will not be taken from any river. For ice road and pad construction, approximately 4,200,000.gallons (100,000 bbls) of water will be used. Ice road and pad maintenance will require approximately 504,000 gallons (12,000 bbls) of water during the sixty to seventy day operation. Approximately 1,050,000 gallons (25,000 bbls) of water will be required for drilling operations. In addition, the camp will need about 420,000 gallons (10,000 bbls). Total water usage for the access road and drilling is estimated at 6.2 million gallons (150,000 bbls). Potable water will be processed through the drilling contractor's water purification system which meets the requirements set by the Alaska Department of Environmental Conservation. 6. Source of Construction Materials Water and snow will be the only material required for road and pad construction. Water will be taken only from approved lakes. No gravel will be required. 7. Methods for Handling Waste Disposal a. Solid non-burnable waste' Large enclosed containers will be delivered to and picked up from the drillsite by the North Slope Borough. Disposal will be at the NSB landfill. b. SQlid burnable waste: Solid burnable waste will be burned on site in a contractor-supplied incinerator in accordance with 18AAC50. This activity is necessary to reduce the frequency of hauled trash removal. Ashes will be buried in the reserve pit or hauled away. c. .Camp waste water disposal: Camp waste water will be processed through the drilling contractor's waste water treatment system. This system will meet the requirements set forth by the Alaska Department of Environmental Conservation. Liquid by- products created by this system have been approved for discharge by the Department of Environmental Conservation. About 4000 gallons of domestic "grey" water is estimated to be discharged daily. The effluent will be collected and hauled to an approved facility. Wastes produced by drilling operations are described below. 8. Disposal of Drilling Wastes During normal exploratory well operations, drilling wastes generated consist of the following: drill cuttings, drill mud, cement and washdown water. All of these wastes are conveyed to and stored in the "reserve pit" excavated below grade. At the end of the project, any pumpable liquids in this pit will be disposed down the well just drilled via underground injection. Liquid waste disposal via underground injection will be possible by the approval of the AOGCC and an ADEC Liquid Waste Disposal Permit. The solid wastes remaining in the reserve pit will be disposed of by burial. These wastes will be contained in the pit by remaining frozen and should not pose any hazard to potential drinking water sources. a. Pit Design The reserve pit will be excavated to the approximate dimensions shown in Exhibit C. The volume of the pit is approximately 26,700 bbls. Since the pit excavation will be done during the winter, the pit walls will have adequate structure stability to contain the intended solid and liquid wastes. Approximately 12,000 bbls of solid and liquid wastes are expected to be generated from this project with the liquid being injected down the well. The liquid/solid level in the pit will be monitored every 12 hours by rig personnel to maintain all wastes 4 feet below the tundra grade. At the end of the project, the solid wastes will be buried at least four feet below the tundra level with native earth and capped with the original organic layer to allow freezeback and thereby achieve permanent containment. b. Wastes Drill cuttings come from the wellbore being drilled. These solids, consisting mainly of clay and silt, are circulated from the bottom of the well to the surface where mechanical equipment separates and conveys them to the reserve pit. The solids control equipment is typically comprised of shale shaker, desander, desilter, mud cleaner, and conveyor belt. These pieces of equipment separate the liquid phase from the drill cuttings. It is estimated that about 2,600 bbls of drill cuttings will be generated during the project. Normally, the drill cuttings discharged to the reserve pit are coated with drill mud. In addition, occasionally some drilling mud is discharged into the reserve pit when it is necessary to reduce the surface volume. During the course of these projects, it is estimated that about 2000 bbls of whole mud will be discharged. The drilling mud proposed for these wells is a fresh water base with only enough additives to maintain certain rheological and density properties. Tabulated below is a list of possible materials to be used and their application in the mud. These additives and their concentrations are included on the EPA approved mud list for OCS drilling. Oil-based muds will not be used. Additives Application Barite Bentonite clays and extenders Chrome free lignosulfonate Caustic soda Soda ash (sodium carbonate) Bicarbonate of soda Polyanionic cellulose polymers Aluminum stearate Biodegradable lubricant Sodium carboxymethylcellulose Lime Partially hydrolyze polyacrylamide copolymer Weighting agent Viscosifier Dispersant/thinner pH control Calcium removal/pH control Calcium removal/pH control Filtrate control/shale inhibition Defoamer Torque and drag reduction Filtrate control pH control/shale inhibition Viscosifier Occasionally, fresh water is used to wash down the solids control equipment as well as other rig mechanical equipment and this "washdown" water will be collected and pumped to the reserve pit. Attempts will be made to minimize this washdown water amount and, at the same time, provide a safe and clean working environment. Additional amounts of water are used to wash the drill cuttings before analyzing them for geoscience purposes. In drilling operations, cement is used to grout the steel casing used in the wellbore. It is estimated that as much as 50 to 100 bbls of excess cement could be discharged into the reserve pit. Hydrocarbons, mostly in the form of diesel fuel and hydraulic oil, are used to run the rig equipment and machinery. These fuels and occasional lubes and greases will all be in containers. Transfer will be done through secure hoses and under strict supervision to avoid spillage. In the event this well is tested, all produced hydrocarbon liquids will be separated from the gas phase in a suitably sized separator. The produced gas will be flared over an excavated flare pit. The flare pit is shown in Exhibit B. No free hydrocarbons will be placed in the reserve pit. c. Pit Closure At the end of the project, the solid and liquid wastes in the reserve pit will be buried by backfilling the pit with the native soils previously excavated and capped with the surface organic layer. The cap will be two to four feet above the tundra grade. Once buried a minimum of 4 feet below the original tundra level, the wastes will freeze and thus be permanently encapsulated. Since the wastes will be below the "active layer", the layer of soil that thaws out each short summer, the frozen wastes will not be mobile nor form any leachate. Two thermistor strings will be installed in the pit to determine the temperature profile and verify that the drilling waste is permanently frozen in place. A site visit during the late summer of the first, third and fifth years is planned to inspect the integrity of the earthen cap and to perform any remedial work needed for site restoration. 9. Disposal of Produced Fluids - Oily Wastes Formation liquids produced during testing operations will be collected and stored in test tanks. The produced fluids will be hauled to and disposed of at an approved oily waste injection site. 10. Ancillary Facilities All equipment necessary for drilling and formation evaluation will stay on the drill site. The camp facility will have the capability to accommodate up to 60 people. No other camps will be necessary. No aircraft landing or service facilities will be necessary. 11. Plan for Site Closur~ Upon completion of drilling and evaluation operations, all muds, cuttings and burned solid waste will be covered over and frozen in place. All other debris will be hauled to an approved disposal site. The well will be plugged and abandoned according to Alaska Oil and Gas Conservation Commission regulations A site visit will be conducted during the first, third and fifth summers following operations to verify the integrity of the pit cap and record thermistor readings. Final site closure will be approved by all appropriate state agencies. 12. Wildlife Acces~ The only wildlife that could be around the location during the winter are owls, ravens, Arctic fox, and possibly and occasional over- wintering caribou. These animals frequent all locations on the Slope. The wastes to be discharged to the pit should hold no attraction for these animals; therefore, wildlife concern is not a significant factor. On-site personnel will be instructed not to feed the wildlife, thereby further reducing the wildlife attraction concern. 13. Safety Hazards The only disposal site safety concern possible would be the potential for a vehicle driving into the pit. This possibility is remote due to pit siting. It is common knowledge to those employed in these operations where the pit is located and that no traffic is allowed there. The fact that the public will not be allowed access to the site also minimizes the potential for a safety violation. The methane gas generation concern associated with public landfills is not a logical probability for this reserve pit. 14. Continaencv Plans -- a. An approved spill control plan will be kept on site at all times for use in controlling accidental discharge of fuels and lubricants. b. Fire, safety and medical emergencies will be handled through available resources at Kuparuk, Prudhoe Bay and Deadhorse, Alaska. c. Well control problems will be handled in a manner commonly accepted as safe oilfield practice utilizing the reserve pit and other resources as necessary. 15.
