TABLE OF CONTENTS SECTION DESCRIPTION OF SERVICES CORE ANALYSIS DATA - TABULATED RESULTS HYDRAULIC UNIT ANALYSIS RESULTS PROFILE PERMEAMETER RESULTS 4 INTRODUCTION Core Laboratories was selected by Arco Alaska Inc. to perform a core analysis study upon samples recovered from the "Nuiqsut" 1 Well, Alpine Field, Umiat Meridian, Alaska. Conventional aluminum inner barrel cores were submitted. Presented herein are the results of analysis. 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 results of the pressure-decay profile pereameter measurements performed upon the slabbed core. An Epilog(g) plot graphically summarizing the core gamma, routine analysis, and hydraulic unit analysis results and an IBM PC compatible floppy diskette containing the results of analyses are supplied in conjunction with the report. Core Processing Cores were handled in the field, and all core processing performed by Core laboratories personnel from our Anchorage office. Core Gamma Surface Log Each core was scanned for natural gamma radiation spectrometer. Total gamma radiation is reported in API units. utilizing Corelab's gamma Core Sampling and Slabbing After the 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 ARCO'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 weighed, wrapped with Saran wrap and aluminum foil, and sealed in a sample jar as drilling was 'completed. After all of the samples were taken, the plugs were packaged and shipped to our Bakersfield Califomia facility. 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 aRer 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 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. ~ma = Mg (1) rg Where: ~ma -- Mg = Vg = Matrix / grain density (g/cc) Grain mass (g) Grain volume (cc) Confining Pressure for Porosity and Permeability MeasUrements Following grain volume determinations, the plug samples were placed into a Hassler-type holder and a confining pressure was applied for porosity and permeability measurements. A confining pressure of 250 psig was used, which is essentially "ambient" conditions, preventing gas by-pass but not acting to compress the sample. Porosity Determination Direct pore volume measurements were performed upon confined samples utilizing Boyle's Law double-cell methods. Porosity values were calculated using Equation 2. ~ = [(VpVp+Vg )1® (2) Where: q~ = Porosity (%) Vp = Pore volume (cc) Vg = Grain volume (cc) Fluid Saturation Calculations Oil and water saturation results were calculated using Equations 3 and 4. So Sw [-~p ] · 100 (3) (4) Where: SO (~o = Vp = Oil saturation (%) Water saturation (%) Fresh sample mass (g) Extracted and dried sample mass (g) Extracted water mass (g) Extracted water volume (cc) Density of oil Pore volume (cc) Permeability to Air Permeability determinations were made following the pore volume determinations again with the samples con£med in Hassler-type holders. Permeability values were calculated utilizing Darcy's Equation for compressible fluids, Equation 5. Where: Ka = Pa p = Qa = L = = Permeability to air (md) Atmospheric pressure Gas viscosity (cp) Differential pressure Mean pressure Flow rate (cc/sec) Length (cm) Bulk volume (cc) Hydraulic Unit Analysis ARer 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 6 and 7. RQI = 0.0314 e~ (6) PR =[ ] rl_~, (7) Where: RQI = Ka = ri) = PR = Reservoir quality index Permeability to air (md) 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 fotmdation 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. Pressure-decay Profile Permeameter (PDPK) The PDPK determines the permeability of a sample by unsteady-state methods using a transient "blowdown" technique. A tank of known volume is first filled with nitrogen and then the gas is discharged through the core sample to atmosphere. The decaying tank pressure is monitored versus time which allows determination of gas flow rate and pressure drop across the sample at any given time. The automated recording of flow rate versus pressure differential provides the data necessary for calculation of a Klinkenberg-corrected permeability as well as the permeability to air. The results of analysis are reported in tabular format and are also presented on diskette in Excel format. ARCO Alaska Inc. Nuiqsut #1 Alpine Field C.L.

NUIQSUT 1 DRILLING AND FOR FIAT!ON The purpose of the NUIQSUT 1 well was exploration. The objective was to ddll a straight hole well to investigate and assess the Alpine Sands in a previously undrilled western location in the Alpine field, and provide potentially vital information before an impending nearby lease sale. A 64' core was drilled in the Alpine Sand Target: (59.4' of core was recovered.) Epoch Well Logging provided RIGWATCH (TM) and Mudlogging services from surface to T.D. The ddlling rig was Pool 'Arctic Alaska'Rig #6. The well was spudded on April 1, 1998, and reached a total depth of 7650' MD (7640' 'I'VD, 7584' SS) on April 10, 1998. LOGGING PROCEDURES Hydrogen flame ionization total gas and chromatograph detectors were employed to detect formation gases. An air motor driven gas trap located at the shale shaker possum belly generated constant mud gas. Sample pumps maintained continuous sample extraction from the trap to the logging unit gas detectors. The gas trap was cleaned and maintained on a regular basis. The chromatograph provided for a frequent analysis of formation gases. The gas system was tested and calibrated on a regular basis. FORMATION SUMMARY A strongly similar type geomorphology and environment of deposition has persisted in the Colviile/North Slope region from pre-Jurassic to the present, and is characterized by a large open Iow continental platform of generally very Iow relief and very Iow gradient, with fairly distant mountains providing the sediment source, and the sediment load carried by varying moderately Iow energy to moderately high energy run-off and being deposited sequentially into a madne platform facies group of delta plain, intradelta, delta front, prodelta, platform deeper marine, basinal deep madne, and moved laterally away from the delta into Iow energy shallow madne and higher energy barrier bar, or episodically surged outward as very high energy turbidites. With the exception of the episodic flooding, the grain/particle load (based on cuttings examination) was limited to clay, silt and finer sand by the time it reached the delta front-prodelta boundary. The massive shale and siltstone sections of NUIQSUT 1 were apparently deposited in quieter zones on the-largesuccessively stacked Iow gradient isoforms that made up the madne portion of the giant continental platform, and thus share many of the same descriptive characteristics. During most of the drilling, very similar looking clay/silt/shale cuttings were logged dudng the downward progression through the geologic column. There was very common to locally dominant interbedded sand, and the occasional massive sand. Very organic-rich shales were pervasive just before, dudng, and after the HRZ marker and were followed by more clay dch shales. There was an Alpine Sand transition ~one with fine. glauconitic sand drilled -from 7335~ to 7392'. The.main Alpine objective was a very fine sandstone from 7392' to at least 7480' and possibly to 7510'. There are many very minor to occasional fair shows in sands above the Alpine. The Alpine Sands have very good to outstanding show properties, abundant bdght yellow sample fluorescerice, pervasive light brown.to pate brownish .orange staining, trace visible oil in mud, good visible porosity, occasional petroleum odor, pale to light straw or light amber cuts in plain light; instant bright milky whitish yellow to bluish yellow cut fluorescence, brown to orangish brown residual ring in plain light, and bright yellow to whitish yellow residual fluorescence.

The permit had plugging procedures up to the surface casing shoe, but did not describe the final surface plug details. The final procedure included setting a ClBP at 300 feet with a cement plug on top of it sufficient to bring cement to the surface. Casing would be cut below ground level with a steel plate welded on top. This plate would leave the well data welded on it. If you need further information, please feel free to call me at 263-4792.

I. Supervisor State of Alaska Alaska Oil and Gas Conservation Commission DATE: April 19, 1998 FILE NO: y99kdsfe. DOC FROM: Chuck Scheve, c...,~ SUBJECT: Petroleum Inspector Surface Abandonment Nuiqsut #1 PTD # 98-025 Sunday, April 19,1998: I traveled to ARCOs Nuiqsut location to inspect the casing cut off and abandonment of this well. The conductor and surface casing had been cut off at 4' below ground level (6'+ below Pad level) and both were found to be full of cement. A 5/8"thick marker plate was welded to the casing with, operator name, well name 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 and rig move operations were under way at the time of this inspection, with only minor amounts of trash and few miscellaneous rig components remaining. SUMMARY: I inspected the casing cut off depth, cement tops and the P&A marker plate on ARCOs Nuiqsut #1 exploration well.

The surface location was moved due to the uneven terrain found at the original location, which would have made building the ice pad more difficult. The planned target location was moved 158 feet east for geological reasons. These changes will require a minimal amount of directional work that will be done per 20 AAC 25.050(b). A revised surface location plat is attached for reference. All other required information is as presented in the original Application for Permit to Drill (APD) dated February 3, 1998. Per conversation with Mr. Blair Wondzell of the Alaska Oil and Gas Conservation Commission on February 17, 1998, the revision to the original APD will be covered under the Well Completion or Recompletion Report and Log (Form 10-407). The ice road is currently being constructed to the Nuiqsut #1 location and Pool 6 will begin mobilization after completion of the CD1-22 well. Estimated spud date is March 25, 1998.

Dear Mr. Zanghi: \Ye have rcvicv,'ed ARCO's letters dated January 27 and 30. 1998. as supplcmentcd by .','our Fcbruan' 9 letter, for a waiver to 20 AAC 25.080(d)(4). The waiver would allow ARCO to dispose of cement rinsatc from Alpine CPool #6} and Kalubik (Doyon #141) cxploratoo' wells down thc annuli of wells located on another pad. specifically whichever well Parker #245 is drilling at time of disposal. Alternatively, ARCO requests authorization to dispose cement rinsate doxvn the annulus of well CD1-22 after it is drilled and mcets annular disposal criteria. Ccmcnt rinsatc is gencratcd from washing cement-mixing cquipment after cementing operations. The x olume of rinsatc is small, about 30-40 barrels per cementing operation. While not exempt, it is primarily water and does not e,'xhibit anv characteristics of a hazardous waste. Because cement nnsatc has not been downhole, it cannot be considered a Class II fluid and therefore cannot be disposed of in a Class II well. Consequently. if not disposed down the annulus of an approved well. it must be hauled to Pad 3 for disposal. The commission docs not bclicvc it is prudent to use Pad 3 for disposing ofccmcnt rinsate. As the principle Class I facility on the North Slope. Pad 3 handles non-hazardous, industrial oily wastes. The limited capacity of Pad 3 should not bc squandcred in processing cement rinsatc. which is essentially water. The commission concludes that cement rinsate from Alpine and Kalubik cxplorator3' wclls may be transported to Parkcr//245 for disposal, or alternatively to CD 1-22 after mccting disposal criteria. This approval is for thc following wells.

Wells drilled in the Alpine area have not seen large amounts of surface gas and seismic data reinforces this, but the nearest offset data is over three miles away. Higher than required mud weights will be used to mitigate any gas that might be present. Shale stability products will be used to treat the reactive shales and the solids in the mud will be kept to a minimum to keep mud weights as low as possible to minimize lost circulation. Nuiqsut #1 APD 02/02/98 PRESSURE ANALYSIS AND PREDICTION ALPINE FIELD NUIQSUT #1 (per 20 ACC 25.005 (c) (7) and 20 ACC 25.033 (e)) An analysis and prediction of over-pressured strata was performed for the Nuiqsut #1 well as required by AOGCC regulations. ARCO does not expect to encounter abnormal pressure from any zones. The prediction is based on evaluation of offset wells in the Alpine (Colville River delta) area. Attached are the following: Mud weight versus depth graph for offset wells Bergschrund #1 & #2, Alpine #1 & #3, Neve #1, Fiord #3 and Nechelik #1. Pore pressure, fracture gradient and anticipated mud weight graph. Pore pressure prediction report based on seismic and sonic data in the Alpine field. There are no shallow hazards (such as shallow gas) expected at this location. There have been 5 wells and 3 sidetracks drilled within the Alpine Field and shallow gas has not been encountered.

Wydrinski PRC-D1139 Telephone: 509-4325 To: D. Gingrich ATO-1458 This letter is to summarize the pore pressure work done in the Alpine area using the Integrated Travel Times (ITT) from a Traverse Line from the 3-D seismic data. The models used to calculate the pore pressure and fracture gradient was developed from an Alpine study done in 1995. There is no shallow hazard pressure anomalies at this well location. Seismic Processing: The accuracy of Geopressure prediction is highly dependent upon the accuracy of the seismic stacking velocity field that is used as input. This velocity field is generated by picking velocities at selected CDP locations with an automated high resolution velocity analysis program (UHCI process developed by AEPT). This process produces an accurate and densely sampled velocity field to cover the selected CDP location. The RMS velocities that are output have been smoothed over 300 ms vertically and 150 CDPs horizontally to normalize any instabilities in the velocity field that might result from noise, lack of signal, or variations in CDP fold. Pressure Prediction Procedure: ARCO's PPFG software was used to calculate the predicted pore pressure. The models used to calculate the pore pressure and fracture gradient was determined from the Alpine study done in 1995. Pore pressure was computed from the Pleistocene model which is: PP = C2 * AAT 2 -I-C'l * AAT + Co where: 1) PP is the predicted pore pressure 2) C2 = -0.00025769; C~ = 0.119231 ; Co = 8.94231 3) DDT is the amount of increase in msec between the Normal Compaction Trend Line (NCTL) and the seismic ITT. An increase of the ITT above the NCTL is an indication of a pore pressure increase. i Nuiqsutl .doc Page Fracture Gradient Procedure: The Eaton method was used to calculate the fracture gradient. The inputs to this method are pore pressure (PP), overburden gradient and Poisson's Ratio. The overburden was calculated from a synthetic density created from the ITT. The Poisson's Ratio used was one developed for West Cameron Gulf of Mexico. These parameters were determined from the Alpine study done in 1995. Seismic Traverse Line Figure #1 is the pore pressure prediction across this line. The warmer the color the higher the pressure. The NCTL used for this line has a slope of-4.5-05 and an intercept of 173. The location of Nuisqut #1 is at CDP 135 and Alpine #1 is at CDP 395. Figure #2 is a comparison on the seismic ITT (TRAI_VEL_DT) and sonic DT (EDT) for Alpine #1. The second track is the comparison of the synthetic bulk density (TRAI_VEL_RHOB) and the wireline bulk density (ERHOB). There is a reasonable comparison between the curves. The third track is the Shale Volume (VSH). Figure #3 is the pore pressure prediction plot of the Nuiqsut #1 (CDP 135 on this traverse line). This actual location on the 3-D seismic is the intersection of cross-line 1397 and in-line 5305. The right portion of the plot is the pore pressure (blue curve) and fracture gradient (red curve). The increase in pressure at 7,400' could be due to a lithology change and not an increase in pressure. There is no shallow hazard indication. The left portion of the plot is the seismic ITT (black curve) and the NCTL (red line). Conclusion 1) There is no shallow hazard indications. 2) The increase in pressure below 7,400' is probably due to a lithology change. 3) The slope and intercept for the NCTL from this line is similar to that from the Alpine study done in 1995.

Nuiqsut #1 APD 02/02/98 ANNULAR PUMPING OPERATIONS ALPINE FIELD NUIQSUT//1 Incidental fluids from drilling operations will be pumped down the nearest dedicated disposal well (1R-18 in KRU) or an approved annulus. (Note that cement rinseate will not be injected down the dedicated disposal well, but will be recycled or held for an open annulus). It is requested that a waiver be granted to 20 ACC 25.080 (d) (2) to be permitted to dispose of incidental fluids as a result of drilling operations on Nuiqsut #1 in approved annulus CD 1-22, which is not located on the same pad. The reason for this request is twofold. First, an annular injection test this winter would answer questions that exist on the viability of annular injection at Alpine for the remote development drilling program planned to begin in February 1999. Secondly, driving to Alpine Drill Site #1 will be safer than having to drive 40 miles on the busy ice road back to the Kuparuk River Unit Class II well. Fluids to be disposed of in the subject annulus will be limited to drilling wastes associated with drilling a well as defined in 20 AAC 25.080 (h).
