Attachments in Duplicate by Wood Well: NK -29 NK -29 IA Cement Job Proposal Interventions Engineer Travis Montgomery: 907-564-4127 Production Engineer Mark Sauve: 907-564-4660 Expected Start Date December 13", 2019 History: NK -29 is a gas -lifted producer drilled in 1997. The well is periodically treated with scale inhibiting chemicals. NK -29 failed warm TIFLs in September 2018. In October 2018, Slickline dummied off the tubing, secured the well with a TTP, and identified a tubing leak @ 18,680' MD using a spinner temperature profile while pumping down the IA at 1 BPM @ 700 psi and taking returns from the tubing. A caliper in 2018 showed the hole at 18,680' MD and wall penetrations ranging from 20% to 34% in 47 of the 481 joints logged. All penetrations exceeding 21% and 34% are at or below 14,770' MD and 17,034' MD, respectively. In February 2019, a MIT -IA passed to 2500 psi with a patch set over a tubing leak at 18,680' MD. New gaslift valves were installed at this time. In May 2019, a new screened orifice was installed after the well was experiencing issues kicking off. The current status of NK -29 is Not Operable. A warm TIFL failed in July 2019. In August 2019, Slickline dummied off all gaslift mandrels, set a 2-7/8" XX -plug set in the nipple reducer at 19,502' MD, and performed a passing CMIT-TxIA to 1436 psi. The tracking of IAP when the tubing was pressurized with a D&D holefinder set down on top of the upper patch packer @ 18,665' MD indicates that a tubing leak exists above the patch. The lack of IAP tracking when the tubing was pressurized with a D&D holefinder set at 18,550' SLM indicates that the tubing has integrity above 18,550' SLM. Scope of Work: Repair tubing leak at 18,680' MD and tubing leak between 18,550' SLM and 18,665' MD with IA cement. By repairing this well with an IA cement squeeze, it is estimated that an incremental 123 mbo can be produced over the next several years. Without an IA remedial squeeze, the well has no utility in the foreseeable future. Background Information: • Tubing leak at 18,680' MD: o Initially discovered with failing warm TIFLs in September 2018. o Spinner temperature LDL and caliper on 10/13/18 found leak depth to be 18,680' MD. • Top of UG4: 8306' MD, 5220' TVDss. • Proposed TOC in IA is 2046' TVD below the surface casing shoe • SBHP on 6/29/2017 recorded pressure of 4332 psi equivalent at 9200' TVDss datum, and temperature of 182 °F • 9-5/8" x 13-3/8" Outer Annulus has open shoe, and has never been pressure tested • TOC of 9-5/8" casing is calculated at 15,943' MD based on 740 sacks pumped with 30% washout Overview Procedure: Slickline and Fullbore: 1. Drift for patch. 2. Pull patch. 3. Pull 2-7/8" XX plug from 19,502' MD. 4. Pull 4-1/2" x 2-7/9" nipple reducer from 19,502' MD. 5. Set 4-1/2" CBP at –19,370' MD in the middle of the first full joint of tubing above the packer. 6. Fire tubing punch from 19,351' to 19,356', across the collar at the top of the first full joint of tubing above the packer. a. Fullbore: pumping down the tubing and taking returns through the IA, confirm circulating rates and pressure through tubing punch. b. Circulate tubing and IA to diesel. 7. Set cement retainer at `19,330' MD in the middle of the second full joint of tubing above the packer. Coiled Tubing: 1. Sting into cement retainer and pressure test. Pumping down coil, establish returns up the IA and pump the following schedule (target TOC in the IA is –13542' MD): a. 5 bbl FW spacer b. 245 bbl Class G cement c. 5 bbl FW spacer d. CT volume of displacement 2. With 1 BBL of cement remaining in coil, disengage retainer and lay the last 1 BBL of cement on the retainer. Note pressures after un -stinging from retainer—do not bleed any pressure. Ensure that retainer is holding pressure, and then circulate or reverse the cement off the retainer and POOH. 3. Wait for cement to gain 500 psi of compressive strength and RIH with milling BHA and junk mill. Mill the retainer, cement, and CBP from the 4-1/2" tubing. Mill/push the remainder of the CBP until it is out of the tubing tail. Slickline and Fullbore 1. Set PX plug in XN-nipple at 19,502' MD. 2. Log SCMT. ' Lb /c0G C S 3.

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.

When noise problems occurred, inflating the dampeners quickly fixed the problem. Due to the learning curve on the IDEAL software, it was imperative to have backup copies of the drilling data at all times. When needing to reboot the computer, it was useful to plan each reboot around the slides, so the rig would not have to wait on the tool face screen on the rig floor. These minor problems are gradually becoming less of a impact as more is found out about them. Anadrill demonstrated by repmgramming our tool to meet the low flow criteria for coting that it was able to assist in the cored sections of NK-29 with both real-time GR and surveying. Anadrill appreciates the opportunity to provide BP Exploration with MWD and LWI) services. Nathan Rose Field Cell Manager ARCO Alaska, Inc.

COall~ JOB PERFORMANCE DIRECTIONAL NK-29 was drilled to 20566.8'. This hole was drilled to 19688' with DSS and GR. Coring runs were tracked from 19688' - 20060. The coring runs were monitored with GR and DWOB/DTOR. CDR and ADN were picked up And reamed from 19000' to 20242'. TD was reached with ADN and CDR at 20566.8'. Real-time inclination and azimuth readings were monitored during slide and kickoff intervals. The Well was controlled drilled for most of the surface hole. MWD real-time GR and direction was used on the first two coring runs. The final survey point was 20504.3 with an inclination of 63.92 degrees and an azimuth of 330.7 degrees. This survey was projected to TI), giving the final bottom hole location: Measured Depth: 20566.8' Tree Vertical Depth: 9398.75' Latitude: 12383.60' N Departure: 10533.18' W Displacement at Azimuth: 16270.32' at 319.56 deg FORMATION EVALUATION Real-time GR was used for lithology identification in every run. Three coring runs were nm done for geological information. In the Ream down section real time ADN and CDR were also used for preliminary evaluation of the production interval. Logs were faxed in and ASCH data e-mailed in a timely manner, which was produced from the memory data when the tool was' above the rotary table. DRILLING MECHANICS DWOB and DTOR was monitored at all times on the rig floor. SPIN was run to provide sticking-pipe indicators. SHOCK Shock is monitored in both the MWD and CDR tools. It remained low most of the well; medium shocks were monitored while moving in and out of the open hole kickoff and reaming. WASHOUT DETECTION Washouts can be spotted by observing MWD turbine rpm, pump pressure, and flow rate. No washouts occurred on this well. 1111 E. 80th Ave. Anchorage, Alaska 99518 TEL (907) 349-4511 FAX (907) 349-2487 Date: 2-19-97 Well Name: NK- 29 Company: Shared SOl'vices Dl'illins API Number: NK-29 5002922724 I,ocation: North Slol~..Air,ica NK-29: Field: Niakuk RiE: Pool Arctic ,~,]~ir~ ~ Anadrin Personnel Field Cell cen Engineers: LWD Engineers: Michael Damm~yet Nathan Rose Dave Frisnegger Jeroen Bosse Mark St. Ameur Field Suppozt: ,~!ost:o District MAnsger: Martin Varco Field Se~ce lV[anagm-: Bill Perry SERVICES PROVIDED Service Directional Survey Service (DSS-~3R) DWOB/DTOR (DSW) Compensated Dual Resistivity (CDR) Azimuthal Density-Neutron (ADN) Service Dates 14 Jan 97 - 17 Feb 97 14 Jan 97 - 17 Feb 97 17 Feb-97 - 20 Feb 97 17 Feb-97 - 20 Feb 97 Depth Iamval 80' - 20060' 80' - 20566.8' 19000' - 20566.8' 19000' - 20566.8' OPERATING STATISTICS Total MWD Pumping Hours: Total MWD Below Rotary Hours: Total MWD Footage: Total MWD R. ns: Total LWD Pumping Hours: Total LWD Below Rotary Hours: Total LWD Footage CDR: ADN: Total LWD Runs: CDR: ADN: 425.8 624.5 20486.8 9 425.97 67.5 1566.8 1566.8 1 1 RECEIVED ;0V 15 1999 Ala~ 0il & ~as ~.

File: DAL-97045 PROJECT SUMMARY Core Retrieval and Shipping - Prudhoe Bay, Alaska (Niakuk Unit) A Core Laboratories' representative from Anchorage was at the wellsite for initial core handling and transportation. The first conventional core was recovered in the field on February 13, 1997. The core barrel liner containing the core was cautiously laid down on the catwalk and was striped with red and black markers along its length to maintain uphole orientation. The liner was depth marked (top to bottom), then cut into three foot lengths with a chop saw. End caps were placed on each end of the tubes containing the core and placed into specially constructed wooden shipping crates. A second and third core was retrieved on February 15 & 16, 1997 and the above procedure was repeated. The tubes containing core were placed in the shipping crates and air-freighted to Core Laboratories' Carrollton facility for core processing. Core Reception and Processing-Carrollton, Texas The core processing was performed according to a procedural protocol outlined by Arco Alaska, Inc. Three cores totaling 557 feet in length were uncrated and laid out, then run through Core Laboratories' spectral gamma logger to measure total gamma counts, and uranium, thorium, and potassium isotopes. The individual cores were oriented, labeled, marked, and sectioned for routine horizontal and vertical plug sampling. Routine horizontal and vertical core plugs were drilled with Isopar-L. The bottom 32 feet of the third core was not sampled because it was shale. The horizontal plugs were immediately loaded into Dean-Stark glassware for saturation measurements. Approximately every third foot (selected by an Arco, Alaska representative) a special core analysis plug was taken using humidified nitrogen gas as the plugging fluid. These plugs were preserved by wrapping in Saran wrap, aluminum foil, dipping in CoreSeaF" and sealing in ProteCoreTM laminate. The end pieces (trim ends) were placed directly into soxhlets for hydrocarbon extraction. The routine and special core analysis end pieces were forwarded to Arco Piano for thin section preparation. Concurrently, a 1/4 slab was taken' during the core processing. Core chips from each foot were taken for shipment to the State of Alaska. Nine inches per foot of remaining core material was preserved in Saran Wrap, aluminum foil and CoreSeal. All core material (butt ends and slabs), plug samples, and end pieces/wafers were boxed and prepared for distribution. Laboratory Program Routine plug samples were analyzed in strict accordance with Arco Alaska's protocol described in the laboratory procedures. The horizontal plugs were subjected to Dean-Stark saturation determination, cleaning and drying, permeability, porosity and grain density measurements. Vertical plug samples were batch cleaned and tested for permeability and porosity. 1-1 Core Laboratories Arco Alaska Inc.

File: DAL-97045 LABORATORY PROCEDURES Laboratory analytical and quality control procedures used during the analysis of the core from the Niakuk NK-29 well followed the procedural guidelines set forth by Arco Alaska, Inc. Any modifications or additions to the written protocol were by request or by approval of Arco Alaska, Inc. or Arco Piano. Surface Core Gamma Logging Before the commencement of spectral gamma logging of each core run, the equipment was checked with a calibration cylinder with a total gamma ray count of 200 APl units. If the equipment was observed to measure values outside the tolerance limits, then a recalibration routine was initiated using individual standard calibration tubes. The core gamma logger utilizes a Na-I detector of similar configuration to downhole log detectors, and an anti-coincidence shield around the detector to greatly reduce background radiation and reduce Compton scattering to improve the signal to noise ratio. The core travels over the detector under the protection of lead shielding at a slow rate of two minutes per foot. A multi-channel analyzer is interfaced with a PC for digitized data acquisition. Core gamma' data was processed and plotted in depth versus total (APl units), at a vertical scale of 5"= 100 feet and is presented in Section 5 of this report. Preliminary plots were sent to the client as soon as they became available. Slabbing Following the core gamma logging process, a 1/4 slab was cut using a slab saw cooled with liquid nitrogen mist. Slabbing was performed relative to the yellow and white orientation lines drawn on the up dip side of the core. The 1/4 section was then carefully cleaned, labeled and placed in core slab presentation boxes (about nine feet of core per box) with styrofoam liners. The 1/4 slab section was prepared for core photography. Plugging Routine horizontal and vertical core plugs were drilled with Isopar-L. The horizontal plugs were immediately loaded into Dean-Stark glassware for saturation measurements. The special core analysis plugs were taken using humidified nitrogen gas as the plugging fluid. These plugs were preserved by wrapping in Saran wrap, aluminum foil, dipping in CoreSeal and sealing in ProteCore laminate. The routine vertical plugs were batch cleaned to extract hydrocarbons and formation salts. Routine plug end pieces (trim ends) were extracted of hydrocarbons and then placed inside plastic bags and forwarded to Arco Piano. Core chips from each foot were taken for shipment 'to the State of Alaska. Nine inches every foot was preserved in Saran Wrap, aluminum foil and CoreSeal. All core material (butt ends and slabs), plug samples, and end pieces were boxed and prepared for distribution. Core Photography The 1/4 longitudinal cuts of core were used for white light and ultraviolet core photography after careful cleaning and preparation of the rock. Large format (approximately 18 feet per frame) shots were taken and photographs were provided in both white light and UV 8x10 inch prints. CD-ROM formats were also provided of the core photos. Core Laboratories Arco Alaska Inc. File: DAL-97045 Profile Permeability and Porosity Following photography, profile permeability and acoustic travel times were measured every 0.3 feet on the slab sections. Porosity values were calculated from the measured acoustic data using the following formula: = (1N +1)/'S * 100 where: V I S = Porosity, percent Acoustic velocity, ft/sec Y Intercept from calibration plot Slope from calibration plot After the profile permeability and porosity determination, the 1/4 slabbed core was shipped to Arco Alaska's core storage facility in Anchorage. Plug Samples Horizontal and vertical plugs were routed to the extraction and leach room for Dean-Stark saturation determination and/or batch cleaning of residual hydrocarbons and formation salts. Dean-Stark Analysis Each Dean-Stark flask and associated glassware were cleaned and dried before use. The condenser, core chamber and flask were rinsed 5 times with 20cc of fresh reagent grade toluene before adding toluene to the apparatus for pre-boiling. The sidearm was checked for water and pure toluene was transferred from sidearm to flask, the sidearm was then dried. Each core plug sample was removed from its Saran Wrap seal, then weighed to 0.001 g, placed in a predried and prelabelled thimble and weighed again. Each plug and thimble was then loaded into the Dean-Stark apparatus. The system was sealed with Teflon tape to prevent leakage and capped with desiccant to prevent the introduction of condensed atmospheric water. Water volume in each Dean-Stark receiving tube was monitored during the toluene refluxing until stabilization. A wire was 'used to swab off any water droplets from the neck of the condenser. A record of time and water volumes was kept for each sample. Extraction time for each sample was approximately 48 hours. After extraction, the flask and contents were removed. The toluene in the side arm was removed and added to the flask. The water recovered in the side arm was poured into a storage bottle, sealed, and labeled for possible tracer analysis. Sample Drying Each core plug and thimble was dried in a convection oven at 180°F for four hours, followed by 24 hours drying in a vacuum oven at 180°F. Sample weights were monitored approximately every 4 to 24 hours until weight stabilization (+/- .01 g) was achieved. After drying, each plug and thimble was allowed to cool in a desiccator and then weighed to 0.001 g. Each plug was removed from its thimble and carefully brushed to remove fines, labeled and reweighed. Core Laboratories 2-2 Arco Alaska Inc. File: DAL-97045 Grain Volume Determination Grain volumes were measured using the Boyle's law AutoporosimeterTM which was calibrated and checked with a known volume steel disk and Berea Sandstone (2.65 g/cc) check plug before each run. Plug samples and tracer samples were kept in a desiccator until ready for grain volume measurement. After every five samples, the steel check disk was measured to ensure correct equipment operation. Equipment recalibration was performed a minimum of twice a day or as needed. Grain densities (gm/cc) were calculated using the dry sample weight (gm) and grain volume data (cc). Plug Porosity and Permeability Measurements by CMS-300TM Horizontal plug samples were measured for permeability and porosity by the CMS-300 at 2500 psi net overburden, every tenth plug between 19,735' and 20,125' were ran at three overburdens (800, 1500 and 2500 psi). Before each group of samples was run, a standard system leak test was performed to ensure correct equipment operation. Calibrated, known volume check cylinders were run before and with each carousel suite of samples. The Klinkenberg (slip corrected) permeability for each plug sample was determined as a function of pressure decay (helium blow-down). A reference cell of known volume charged the sample with helium. A downstream valve vented the sample to atmosphere, and the change in pressure with time was monitored. The multiple flow regime data allowed the determination of Klinkenberg permeability of the sample, a calculated air permeability, along with parameters helium slip factor (b) and the inertial resistance factor (~) beta. Any plug with permeability to air of 3000 md or more was remeasured using the Autopermeameter (a steady-state device), which has greater accuracy in measuring higher permeability samples, and the Autopermeameter data was reported. Porosity for each plug sample was calculated using Boyle's law by the CMS-300TM with grain volume and pore volume by: : (PV · 100) / (PV + GV) where: O PV = GV = = Porosity, percent Pore volume at net confining pressure, cc Grain volume, cc Data was downloaded to diskette, imported to the core analysis report software, and preliminary data printouts were provided to the client regularly. Samples unsuitable for CM$-300TM testing were subjected to ambient condition porosity and profile (probe) permeability testing and are noted in the tabular data. The horizontal plug data is presented with the fluid saturation data in tabular format in Section 3. Vertical Plugs A vertical' plug was taken every fifth foot just below the horizontal plug. The slabbed four inch routine core section adjacent to the horizontal plug sampling points were used to obtain vertical plug samples. Testing of vertical plug samples .included permeability and porosity by CMS-300TM at 800, 1500 and 2500 psi confining pressure and grain density measurements. The results are found in Section 4.

The well was recently put on production and produces 4500-5000 bopd with GOR increasing to near the 100% limit over Niakuk initial GOR. The request to keep producing is reasonable for a short period, several days at least, until they can get the bottomhole pressure equipment lined up and a test designed. The initial reservoir data will be important for planning purposes. ~/~ I recommend approval of the request. Diana File: PT ARCO Aleaka, Inc. {.

('ARCO"), for itself and on behalf of Exxon Company, USA ("Exxon"), hereby requests approval to initiate a second lease operation on ADL 34626 for a period of 30 days from the start of initial production. ARCO will serve as the lease operator for the NK-29 Lease Operation, pending the formation of a new or expanded participating area. West Niakuk Well #3 (NK-29), drilled to a total depth of 20,566' MD-RKB, has penetrated oil bearing Kuparuk River Formation. Facility tie-in work is complete and the well is ready for initial production. The bottom hole locatiOn of the top Kuparuk River Formation based on the MWD surveys is 2396' FSL, 675' FEL, Sec. 22, T12N, R 15E, UM. Lease ADL 34626 has a royalty rate of 12.5% and is owned 50% each by ARCO and Exxon. West Niakuk #3 was drilled from Heald Point and has access to Greater Point Mclntyre Area and IPA shared facilities. The well will be production tested at the Heald Point facility and commingled with other Niakuk/Lisburne production for processing at the Lisburne Processing Center (LPC). Production allocation will be based on the existing well test methodology approved by the ADNR, ADOR, and AOGCC. Production from West Niakuk #3 will be reported separately for volume accounting, royalty, and production tax purposes. It is our understanding that the 1980 Prudhoe Bay Settlement Agreement as well as ARCO's and Exxon's ANS Royalty Litigation Settlement Agreements and ANS Gas Royalty Settlement Agreements apply to this well's production.

P O Box 100360 Anchorage, AK 99510-0360 Re: West Niakuk #3 (NK-29) File: Request to Commingle Production Dear Mr. Groth: Well NK-29 (96-190) // Your application to commingle NK-29 was received March 5, 1997. Your request is to commingle production from NK-29 with that from the Niakuk pool in surface facilities prior to processing in the Lisburne Production Center (LPC). The Commission approves surface commingling of production from NK-29 with production from other pools for processing at the Lisburne Production Center. Well test based production allocation shall be used to determine NK-29 production volumes. Allocation data and well test data will be supplied to the Commission monthly in both computer file and report formats along with the data from other pools producing to the LPC. Specifically, ARCO shall determine production allocation according to Rule 6, Conservation Order 329. Any NGL's produced from NK-29 will be allocated based on actual gas production volumes and NGL process simulations. Process simulations must be updated at least one per year based on NGL samples and results reported to the Commission. NK-29 must be tested at least twice each month. If the well has been shut in and cannot meet the twice monthly test frequency, it must be tested within five days of startup. All available test separator capacity within the constraints imposed by operating conditions must be utilized for well testing. Optimum test duration and stabilization time will be determined by the operator. Water volumes will be determined by API/MPMS approved methods, or the use of industry proven, on-line water cut measurement devices approved by the Commission. APl gravity will be determined annually by an API/MPMS approved method. Gas samples will be taken and analyzed for composition from each non gas lifted producing well yearly. x. J.W. Groth March 17, 1997 Page 2 A semi-annual allocation process review will be held with the Commission. Lisburne Production Center allocation review will be held in March and October each year. In the event ofoil production capacity proration at or from the LPC, all commingled pools produced at the LPC. including NK-29, will be prorated by an equivalent percentage of oil production recognizing mechanical limitations and operational constraints.

Original reservoir pressure is 4500 psi at 9200' SS (9.4 ppg EMW). The most likely reservoir pressure--based on NK-13m is estimated at 3975 psi (8.3 ppg EMW). NK-(~8 violates SSD's flowing well criteria from 609' to 759' MD. Even though NK-09 passes the flowing well criteria it does so by less than 2.0 ft from 600' to 900' MD. Consequently, both wells will be shut-in until surface casing is set. NK-07 and NK-08 violate SSD's conventional flowing well criteria from 7,851' to 8,113' and 7,990' to 8,190' respectively. But these wells pass the risk base separation criteria of 1:75 (one chance in 75 of a collision) and may remain flowing provided surface casing is set prior to.entering the "no-flow" intervals. Well Control: Well control equipment consisting of 5000 psi WP pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures.

Take cam when running the packer into the liner. Record the pick up and slack off weights. Land the tubing hanger and RILDS. Test the tubing hanger packoff to 5000 psi. Reverse circulate the annulus to appropriated weighted seawater/brine containing 25 gal/100 bbl's of Corexit 7726. Reverse circulate at 3-4 BPM. Drop ball--the final packer setting method will be determined by the results of NK- 17. Pressure up and set the packer with 3500 psi--setting initiation pressure is 1000 psi and fully set is 2500-3500 psi. Maintain the tubing pressure for 30 minutes after setting the packer and record it as the tubing test; bleed off pressure. 3500 psi setting/test pressure is to minimize the possibility of the shear-out sub shearing early. * If the SSSV closes at any time (can occur while landing the tubing hanger and while threading the control line(s) through the wellhead), the SSSV must be re-opened prior to attempting to shear out the shear valve in the top GLM station. · Consider that trapped (initial) pressure below a closed flapper valve will increase due to the effects of BHT over time. · The control line pressure should not exceed the pressure rating of the weakest link of the wellhead system. Set the "tw.o way" check. Nipple down the BOP's. Nipple up the tubing head adapter and tree. Test the control lines to 5000 psi. Test the tubin . · Pull the "two " g head adapter and tree to 5000 si way check with a lubricator P · Pressure up the tubing to 2500 psi. This will keep the RP valve from shearing while testing the backside. Pressure up to test the packer and annulus to 4000 psi. Maintain the pressure for 30 minutes. Record the test on a chart. Bleed off the annular pressure, pressure up the tubing to 4500 psi to shear the tubing shear out sub. Note: The pressure in the control line needs to be higher than the tubing pressure to keep the valve open. If no adjustment is made the TRSSSV will close while setting the packer and you will be unable to shear the RP valve. Pressure up the annulus to 2900 psi to shear the RP valve in the top GLM. Displace the tubing with enough diesel to freeze protect the annulus and tubing to 2,200' tvd. U-tube well so pressure has equalized on both sides. Set a BPV in the tubing hanger using a lubricator. Install all needed flanges and needle valves. Label all of the control/injection ports, including those that are blanked off. Close all valves. Release the rig and move it off location.

DOC Tuesday January 14, 1997: I traveled to Pool rig #7 in the Niakuk field to witness the Diverter function test. . The function test of the Diverter assembly went well. The twenty inch annular preventer had a closure time of 28 seconds which is outstanding for this equipment. The accumulator had a recharge time of 2 minutes 25 seconds. The gas detection system was tested and worked well. I walked the vent line and found a good solid construction of ample length and solidly anchored. The location though crowded was well organized allowing good access to the rig. ~UMMARY: I witnessed the Diverter function test on Pool rig #7 no failures noted. Attachments: ezlkanee.

West Niakuk No. 3 November 26, 1996 IT APPEARING THAT: , . ARCO Alaska, Inc. submitted an application dated October 31, 1996 requesting exception to the well spacing provisions of Title 20 AAC 25.055 (3) to allow drilling the ARCO West Niakuk No. 3, delineation oil well to a producing location within 500 feet of a quarter-section line within an undefined oil pool in the Prudhoe Bay Unit on the North Slope. Notice of opportunity for public hearing was published in the Anchorage Daily News on November 2, 1996 pursuant to 20 AAC 25.540. The Commisson recieved one protest to the application, which it rejected because the property interest claimed by the protester was several miles away fi.om the proposed producing location for the West Niakuk No. 3 well. FINDINGS: . , The West Nialmk No. 3 delineation oil well will be drilled as a deviated hole with a surface location 1274' from the south line (FSL) and 1088' fi.om the east line (FEL) of Section 36, T12N, R15E, Umiat Meridian (UM) and a proposed producing location 2406' FSL and 662' FEL of Section 22, T12N, R15E, UM. Offset owners BP Exploration (Alaska) Inc., Emxon Corporation and the State of Alaska have been duly notified. An exception to the well spacing provisions of Title 20 AAC 25.055 (3) is necessary to allow the drilling of this well. CONCLUSION: Conservation Order No. 38{~ ~ November 26, 1996 Page 2 Granting a spacing exception to alloxv drilling of the ARCO West Niakuk No. 3 well will not result in waste nor jeopardize correlative rights. NOW, THEREFORE, IT IS ORDERED: ARCO Alaska, Inc.'s application for exception to the well spacing provisions of Title 20 AAC 25.055 (3)for the purpose of drilling the ARCO West Niakuk No. 3 is approved.
