Location Clearance Exploratory Tarn 2,3, 3A and 4 PTD #'s 97-11, 97-24 97-36 & 97-25 Tuesday July 15, 1997: I traveled to KRU and accompan~Arco representative Larry Brown, Leon Linch, DNR and Raymond Peterson, DEC to the following 4 exploratory locations to conduct the location clearance inspections: TARN #2, PTD 97-0011 TARN #3, PTD 97-0024 TARN #3A, PTD 97-0036' TARN #4, PTD 97-0025. I found all the referenced locations and ice road route~clean and devoid of debris. The only evidence of the well location was a mound of overburden covering the well bores. These mounts were still frozen and had not yet had time to subside however there was signs of vegetation returning to the overburden. I recommend that these location be approved for final abandonment. SUMMARY: I conducted location clearance inspection on Arco's exploratory wells Tarn 2, 3, 3A and 4.

TABLE OF CONTENTS SECT]ON DESCRIPTION OF SERVICES CORE ANALYSIS DATA - TABULATED RESULTS CORE ANALYSIS DATA - TRACER CORRECTIONS HYDRAULIC UNIT ANALYSIS CORE INVENTORY 5 INTRODUCTION Core Laboratories was selected by Arco Alaska Inc. to perform a core analysis study upon samples recovered from the "Tarn" 2 Well, Kuparuk River - SW Field, Umiat Meridian, Alaska. Conventional aluminum inner barrel cores were submitted. Presented herein are the results of analysis. This report is divided into five sections. The first section provides a description of services. The second section contains the tabulated results of standard PKS analysis. The third section presents saturation data corrected for imbibed coring fluid. Hydraulic unit information in a tabular presentation is included in the fourth section, and the final section contains an inventory of the recovered core and preserves. An Epilog® plot summarizing the spectral gamma, routine analysis, and hydraulic unit analysis has also been included. In conjunction with the report, the results of analyses are supplied on an IBM PC compatible floppy diskette in both ASCII and Excel formats. Core Processing The cores were shipped from Alaska to Bakersfield California by ARCO Alaska via Lynden Transport. Upon receipt, the core material was immediately removed from the aluminum sleeve, marked for depth at one-foot intervals and placed into three-foot long core boxes. Spectral Gamma Surface Log Each core was scanned for natural gamma radiation utilizing Corelab's gamma spectrometer. Prior to performing the gamma log on the recovered cores, a scan of a 200 API calibration standard was performed and plotted to confirm proper operation and calibration of the gamma spectrometer. The cores were passed then through the spectrometer's detector at a rate of one half foot per minute. Total gamma radiation and uranium-free gamma radiation are reported in API units. Potassium, uranium, and thorium are the elements primarily responsible for a typical rock gamma spectrum. The concentrations of uranium and thorium are reported in parts per million and that of potassium is reported in percent. Core Samplin§ and Slabbing After spectral gamma measurement, a sample segment approximately three tenths of a foot long was taken from each foot of core for plug sampling. The remaining core from each foot was slabbed parallel to the core axis utilizing a one/third - two/thirds cut. Liquid nitrogen was used as the blade coolant. The one-third sections were placed into slab boxes with styrofoam inserts for viewing, sample selection, and description by ARCO's representatives. The two- third bulk core sections were preserved by wrapping with six layers of Saran wrap, three layers of aluminum foil, and then dipping in Core Seal. Sample Preparation Both horizontally and vertically oriented one-inch diameter plugs were drilled from each of the three-tenth foot core sections taken for sampling. Isopar mineral oil was used as the bit coolant and lubricant. Each plug was wrapped with Saran wrap and aluminum foil and sealed in a sample jar as drilling was completed and then carried upstairs for immediate loading into the Dean-Stark extractors. Analysis Techniques Fluid Extraction Samples were weighed and placed into tared extraction thimbles. Water and the oil were extracted from the samples by Dean Stark methods with toluene as the solvent. The samples were held in the Dean Stark extractors for a minimum of sixteen hours and were removed only after no further water was recovered in the receiving tubes. Complete hydrocarbon extraction was conducted using soxhlet extractors with methylene chloride as the solvent. Cleaned samples were removed from the soxhlets and dried in a convection oven at 180°F for six to eight hours and then placed into a vacuum oven at 180°F for a minimum of forty-eight hours and then monitored for weight stability. The dried samples were cooled to laboratory temperature in a desiccator prior to analysis. Grain Density Determinations Grain volumes were determined using a Boyle's Law extended range helium porosimeter. Metal jacket and end-screen weight and volume corrections were applied to the jacketed samples. Grain density was calculated using Equation 1. Dina = Mo/ Vo (1) Where: Dina Vo = Grain Density = Grain Mass : Grain Volume Porosity Determination Indirect pore volume measurements were made upon the plug samples. mercury displacement pump was used to determine the bulk volume of each plug and the pore volumes were then calculated using Equation 2, and porosity was calculated using Equation 3. V. = Vb - V= (2) ~ = [Vp/ (Vp + Va)] x 100 (3) Where: Vb V= Vp = Bulk Volume : Grain Volume : Pore Volume : Porosity, Percent Fluid Saturation Determination Oil and water saturations were calculated using Equations 4 and 5. So : [((W~ - We - HeO)/Do)/Vp] x 100 = [H:~O/Vp] x 100 (4) (5) Where: So Sw W1 = Oil Saturation, Percent : Water Saturation, Percent : Natural Weight = Extracted and Dried Weight H20 -- Extracted Water, Density Assumed 1.0 gm/cc Do = Density of Oil, 38 API° Vp : Pore Volume Permeabi 1 i ty to Air Permeability determinations were made following the pore volume determinations. Samples were confined in Hassler-type holders with 400 psi confining pressure for permeability measurements. Permeability values were calculated utilizing Darcy~s Equation for compressible fluids, Equation 6. Pa vo (1000) Qa x L2 (6) (P1 - Pe)(P1 + Pe) Vb Where: Ka Pi - P2 (Pi + P~) = Permeability to Air = Gas Viscosity = Differential Pressure : Mean Pressure 2 Pa : Atmospheric Pressure Qa = F1 ow Rate L = Length = Bulk Volume Water Saturation Corrections from Tracer Analysis Following core measurements and resolution of some questions concerning grain-density results, alternate plugs (even-numbered) were crushed and extracted with distilled water as per ARCO~s protocols. The extracted fluids were shipped to CPM Laboratories for analysis as per ARCO~s instructions. Bromide concentration in the Dean-Stark waters was calculated using Equation 7. CBrDS = CBrDW X (VDw / VDS) (7) Where' CBrDS CBrDW VDW VDS = Bromide concentration in Dean Stark water = Bromide concentration in Distilled Water = Volume of distilled water for extraction : Volume of Dean-Stark water extracted . Filtrate saturation in the core plug water was calculated using Equation Stilt : Sw X (CBrDS / CBrMud) (8) Where: Stilt Sw CBrDS CBrMud : Filtrate saturation in plug : Calculated water saturation (fraction) = Bromide concentration in Dean Stark water : Bromide concentration drilling mud The corrected water saturation was calculated using Equation 9. Scw = Sw - Stilt (9) Scw Sw S flit = Corrected water saturation = Calculated water saturation {fraction} : Filtrate saturation in plug Hydraulic Unit Analysis After rock property measurements had been completed, a hydraulic unit analysis was performed. Reservoir quality index (average pore throat size) and pore .ratio values were calculated for each sample using Equations 10 and 11. RQI : 0.0314 X SQRT(K/PHI) (10) PR = PHI/(1-PHI) (11) Where' RQI K PHI PR = Reservoir Quality Index = Permeability to Air : Fractional Porosity = Pore Ratio RQI and PR values were cross-plotted on a log-log scale and the data grouped into hydraulic units. Each hydraulic unit represents a unique pore geometry relationship and provides the foundation for the integration of core and electric log data. The results are presented in two tabulated formats; first sorted by sample depth, and then sorted by hydraulic unit; to facilitate selection of representative samples for any additional testing. Core Photoqraphy After scraping the one-third core sections to remove cuttings and saw marks, composite photographs were taken under simulated natural and ultra-violet lighting conditions. The results of photography were presented under separate cover. Sample Disposition The one-third slabbed core was returned to ARCO Alaska Inc. in Anchorage upon completion of core photography. The bulk two-thirds core preserves were shipped to ARCO~s research facility in Plano Texas.

International Airport Rd. Anchorage, Alaska 99516 (907)563-1592 ARCO Alaska, Inc. Tarn #2 Processing Notes Run 1 February 14, 1997 Western Atlas acquired a Vertical VSP and an Offset VSP for ARCO on February 15, 1997 on their Tarn #2 well. The data were acquired using the Western Atlas 3 component tool to record the downhole signal. The source signature was generated by an AHV3 vibrator truck sweeping 8-84 hrz for 4 sec. The same proceedure was used for both offset positions, recording the same geophone positions. The VSP data were acquired in cased hole, areas of the well bore were poorly cemented affecting the seismic signal in some zones. Overall quality of the data was good. Vsp and Offset processing involved attempts to minimize the effect of ringing signals and optimize zones of good data. The wireline logs were acquired in open hole and were effected by washouts in some zones. The well was deviated, the data were corrected to TVD using the Anadrill directional data. The DSI compressional sonic was drift corrected to the VSP velocities and processed through to a synthetic. The results are contained in this report. The offset VSP was acquired to determine AVO response. This data were processed through the AVO processing chain and included in this report. In addition to normal processing logs and vsp corridor stack were imported into IESX for synthetic computations and correlation to the surface seismic lines provided by Arco. These plots are included in this report. Ramona Sines GeoQuest Anchorage, Alaska IIV~STERN ATLAS Atlas Wireline Services TRANSMITTAL FORM FROM: TO: Atlas Wireline Services 1200, 505 - 3rd STREET S.W.

The PSRT wireline tool is stuck in the tubing string in a landing nipple at 5294', The stuck wireline tool plugs the tubing string preventing flowing the well or pumping into the well. Previous efforts to remove the tool with slickline and coiled tubing have been unsuccessful. A rig workover is required to pull the tubing, remove the wireline tool, rerun the tubing and return the well to production test. General Procedure: 1. Move Doyon Rig 141 onto Tarn #2 well, 2.. Kill well as required. Ensure well is dead. 3. Remove tree. Install and test BOP. 4. Pull tubing out of production packer. Circulate and monitor well. 5. POOH with tubing. Lay down landing nipple with fish. 6. Install new landing nipple. Rerun tubing. Pressure test annullus. 7. Remove BOP. Install and test tree. 8. Move rig off.

Plug Arco Tarn #2 Exploratory PTD 97-0011 Wednesday~ February 12, 1997: I traveled to Arco's Tarn #2 Exploratory Well to witness the tagging of the second open hole cement plug. The well had been drilled to a TD of 7,650' to obtain information on formations below the 7" casing setting depth. The open hole portion, below the proposed 7" casing shoe, wes plugged back to 6,260' with two balanced cement plugs. Plug #1, 51' bbls of 15.8 ppg Class G Cement set from TD (7,650') to 6,941 (calculated TOC). Plug #2, 31.5 bbls of 15.8 ppg Class G Cement, set from 6,594 to 6,260', 40' above the proposed 7" casing shoe set point (6,300'). After WOC for 12 hours we tagged the TOC at 6,276, the plug would take 15,000~ of drill string weight but appeared soft on top, the cement wes given an additional 6 hours to cure, at which time the TOC wes verified with 25,000~ of drill string weight at 6,260'. The cement was then drilled to 6,300' and the 7" casing run. SUMMARY: I witnessed the tagging of the open hole isolation cement plug at Arco's Tarn #2 exploration well on Doyon Rig 141.

As the attached AOGCC BOPE test report shows the test lasted 3.5 hours with three failures. The door seal on the bottom pipe rams leaked this was tightened and retested. One valve downstream of the choke developed a slow leak, This valve was repaired and retested by Doyon personnel the next day. The H2s and Methane gas detectors both registered higher levels than the test gas applied and the alarms on the methane gas detectors were set at 40% and 60% instead of the required 20% and 40%. The gas detectors are to be recalibrated and the AOGCC notified. The testing went well with good test procedures being employed by the Doyon crews. The rig was clean and ali related equipment appeared to be in good working order.

Dear Mr. Wondzell: ARCO hereby requests a waiver to the AOGCC Regulations covering Annular Disposal of Drilling Waste adopted by the Commission on January 31, 1996. This waiver is requested to cover ARCO's drilling operations on the TARN exploration wells #2,3,4. The waiver being requested is to Section (d), Part (4) of 20 AAC 25.080., which limits the ,'mnular disposal of drilling waste, to drilling operations on the same drill pad as the annulus being injected into. ARCO requests the AOGCC grant permission to allow 'drilling waste' from the TARN exploration drilling operations, be injected into flae annulus being used at that time by Parker Rig 245. All fluids which are brought to the surface in connection to drilling and completing the wells will be transported to and injected down a Class II disposal well (2M-23). All drilling solids generated from these operations will' be transported to CC-2A for grind mad injection. The only fluids which will be transported to Parker Rig 245 and put down ma annulus, will be fluids incidental to drilling and completion but have not been brought to surface.

A weekly status report is required from the time the well is spudded until it is suspended or plugged and abandoned. The report should be a generalized synopsis of the week's activities and is exclusively for the Commission's internal use. 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.

For the nearest offset, Tarn #1, sonic log interval transit times were plotted and pore pressure and fracture gradient curves derived. Again, no indications of abnormal pressure or weak formations were seen. The mud weights planned for Tarn #2 are conservatively based on those used during drilling of the offsets, though the Tarn #1 ITT plot implies lower mud weights would be adequate. The 9-5/8" surface casing shoe will be tested to leak-off upon drilling 10 foot of new formation. ARCO Tarn #2 PRESSURE INFORMATION AND CASING DESIGN (per 20 AAC 25.005 (c) (3,4) and as required in 20 AAC 25.035 (d)(2)) DISCUSSION The following presents the data used for calculation of the allowable surface pressures (ASP) used for the design and drilling of Tarn #2.

ARCO does not expect to encounter abnormal pressure from any zones. The prediction is based on an evaluation of offset wells Tam #1, Cirque #2, Bermuda #1 and West Sak #20. Attached are the following: Mud weight versus depth graph for these wells. Sonic log interval transit time analysis for Tarn #1. Pore pressure, frac pressure & anticipated mud weight graph. There are no shallow hazards (such as shallow gas) expected at Tam #2. The four referenced offset wells indicate no overpressured intervals or lost circulation zones. Therefore, ARCO requests a waiver from 20 ACC 25.005 (c) (8).

GENERAL DRILLING PROCEDURE ARCO Tarn #2 Move in and rig up Doyon #141 over pre-installed 16" conductor. Install diverter system. Drill 12-1/4" hole to 9-5/8" surface casing point (2,745' MD)according to directional plan. Run and cement 9-5/8" casing. Install and test BOPE to 5000 psi. Test casing to 4600 psi (80% of rated burst strength). Drill out cement and 10' of new hole. Perform leak off test. Drill 8-1/2" hole to 7,815' MD TD, coring as necessary, according to directional plan. Run open hole evaluation logs. If the well is to be tested, run 7", 26#, L-80, BTC-M production casing. (If significant hydrocarbon zones are present above the Tarn interval, sufficient cement will be pumped for isolation in accordance with Rule 20 AAC 25.030. Alternatively, if significant hydrocarbon zones occur within 200' TVD of the surface casing shoe, cement will be down squeezed in the annular space between the surface and production casing after the primary cement job is completed.) If the well will not be tested, P&A it per AOGCC regs. Complete the well with 3-1/2", 9.3#, L-80, EUE 8rd tubing. ND BOPE. NU upper tree and test to 5,000 psi. Shut in and secure well. RDMO Doyon #141. Hook up well for flow testing to sudace tanks. Produced fluids to be trucked to Kuparuk production facilities. Test zones as appropriate, abandoning each using a CTU.
