Kuparuk River Field Umiat Meridian, Alaska Sec. 34-TlON/RTE CL File #57111-97095 Dear Ms Harmon: Conventional aluminum inner barrel cores were submitted to our Bakersfield laboratory for testing and analysis. Accompanying this letter, please find the results of this study. We appreciate this opportunity to be of service to you and to ARCO Alaska, Incorporated. Should you have any questions, or if we may be of further assistance, please contact us. Very truly yours, L ervisor Rock Properties JUL, 2 9 '~997 JLS:nw 8 original reports, 8 diskettes: Addressee Core Laboratories, Inc. 3430 Unicorn Road, Bakersfield, California 93308, (805) 392-8600, Fax (805) 392-0824 TABLE OF CONTENTS SECTION DESCRIPTION OF SERVICES CORE ANALYSIS DATA - TABULATED RESULTS HYDRAULIC UNIT ANALYSIS CORE INVENTORY INTRODUCTION Core Laboratories was selected by Arco Alaska Inc. to perform a core analysis study upon samples recovered from the "Tarn" S Well, Kuparuk River - SW Field, Umiat Meridian, Alaska. Conventional aluminum inner barrel cores were submitted. Presented herein are the results of anal~vsis. This report is divided into four sections. The first section provides a description of services. The second section contains the tabulated results of standard PKS analysis. Hydraulic unit information in a tabular presentation is included in the third section, and the final section contains an inventory of the recovered core and preserves. Epilog® plots summarizing the spectral gamma, routine analysis, and hydraulic unit analysis have 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 Los Angeles California by ARCO Alaska and then transported to Core Laboratories' Bakersfield facility by Core Lab personnel. 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 Loq 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 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 Sampl i nq and S1 abbi nq After the spectral gamma measurement, a sample segment approximately three tenths of a foot long was taken from each foot of core for horizontal and vertical 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. For photography, viewing, description and additional sample selection by ARC0's representatives the one-third sections were placed into slab boxes with styrofoam inserts. Each of the approximately seven tenths of a foot segments of the two-third bulk core (left after the material for the plug samples had been removed) 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 taken with horizontal orientation 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, Samples designated for vertical permeability determinations were "batch" cleaned in large Dean Stark extractors with toluene to remove water and then transferred to soxhlet extractors for batch cleaning with methylene chloride. Drying was performed as for the horizontal plugs prior to permeability measurements. Grain Densit,¥ Determinations Grain volumes of the horizontal plugs were determined using a Boyle's Law extended range heliumporosimeter, Metal jacket and end-screen weight and volume corrections were applied to the jacketed samples, Grain density was calculated using Equation l, Dina = Mg / Vg (1) Where' Dma : Grain Density Mg : Grain Mass : Grain Volume Porositw Determination Indirect pore volume measurements were made upon the horizontal plug samples, A 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, Vp = Vb- Vg : EVp / (Vp + V~)] x 100 (2) (3) Where' Vb Vg Vp ¢ = Bulk Volume = Grain Volume = Pore Volume = Porosity, Percent Fluid Saturation Determination Oil and water saturations were calculated using Equations 4 and 5, So = [((W1 - W2 - H20)/Do)/Vp] x 100 = [H20/VpI x lO0 (4) (5) Where' So S= W~ W= HmO Do V~ Oil Saturation, Percent Water Saturation, Percent Natural Weight Extracted and Dried Weight Extracted Water, Density Assumed 1.0 gm/cc Density of Oil, 38 API° Pore Volume Permeabilit.w 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 vg (1000) Qa X L2 Ka = X (6) (P~ - P2)(P1 + P2) 2 Vb Where' Ka Vg P1 - P2 (P1 + P2) 2 Pa Qa L Vb Permeability to Air Gas Viscosity Differential Pressure Mean Pressure Atmospheric Pressure F1 ow Rate Length Bulk VolUme H,ydraulic Unit Anal,ysis 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 7 and 8. RQI : 0.0314 X SQRT(K/PHI) PR = ?HI/(1-PHI) (7) (8) Where- RQI : Reservoir QUality Index K : Permeability to Air PHI = Fractional Porosity PR : 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 Photoqraph,y 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 Upon completion of the core photography, the one-third slabbed core was returned to ARO0 Alaska Inc. in Anchorage . The bulk two-thirds core preserves were shipped to AROO's research facility in Plano Texas. Arco Alaska Inc.

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 accompaneiArco 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.

The conductor and surface casing had been cut off at 5' below ground level and both were full of cement. A plate was welded over the casing with, operator name, well # and lease # bead welded to it. Gravel will be placed in the cellar and the location will need to be inspected this summer to check for subsidence. Clean up operations were under way at the time of this inspection and only minor amounts of trash remained. SUMMARY: i inspected the casing cut off depth, cement tops and the P&A marker plate on ARCOs Tarn #3 exploration well.

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. 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. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. · ~h:i:RD~COMMISSION dlffEnclosures cc: Department of Fish & Game, Habitat Sec'lion w/o encl.

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 #3 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 #3 PRE$$t, JRE ANALYSIS AND PREDIOTION (per 20 ACC 25.005 (c) (7) and 20 ACC 25.033 (e)) DISCUSSION: An analysis and prediction of overpressured strata was performed for the ARCO Tarn #3 well as required by AOGCC regulations. ARCO does not expect to encounter abnormal pressure from any zones. There are no shallow hazards (such as shallow gas) expected at Tarn #3. The prediction is based on an evaluation of offset wells Tarn #1, Cirque #2, Bermuda #1 and West Sak #20 and seismic interpretation. 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.
