ATLAS #1 WELL COLVILLE DELTA UMIAT MERIDIAN, ALASKA CL FILE 57111-01035 Performed by: Core Laboratories 3430 Unicorn Road Bakersfield, CA 93308 (805) 392-8600 Report Presented 11-June-O1 INTRODUCTION Phillips Petroleum Company selected Core Laboratories to provide field handling and analytical services for cores recovered from the subject well. Core Laboratories personnel handled the core in the field and prepared it for shipment to our laboratory in Anchorage. Services provided at the Anchorage facility included core gamma surface log, core sampling, slabbing, and photography. Drilled sample plugs were forwarded to Core Laboratories' Bakersfield location for analysis. Standard porosity, permeability and fluid saturation determinations were performed on all horizontally oriented samples. Vertically oriented samples were tested for permeability only. Presented herein are the results of the analysis performed in Bakersfield with a brief description Of the requested procedures and tests. In conjunction' with the report, the core analysis results are supplied in Excel format on floppy diskette. We appreciate this opportunity to be of service and hope these data prove beneficial in the development of this reservoir. DESCRIPTION OF SERVICES Sample Preparation Samples were received wrapped with Saran and foil and sealed in plastic sample jars.. Upon receipt, each sample was weighed and its weight compared to that recorded in Anchorage prior to shipping. The samples were then unwrapped, labeled, and reweighed. If the samples appeared fragile they were mounted in thin-walled metal jackets with 120-mesh stainless steel end-screens installed on each to prevent sample loss. The sleeves and jackets were seated under hydrostatic loading at 1000 psig Fluid Extraction 'Water and the oil were removed from the samples by Dean Stark methods using toluene as the solvent. Dean Stark extraction was performed for a minimum of sixteen hours, and was terminated when the volume of water collected in each sample's receiving tube had stabilized. Complete hydrocarbon extraction was accomplished using soxhlet extractors with a 70:30 methylene chloride/methanol mixture as solvent. Fully cleaned samples were taken from the soxhlets and placed in a convection oven at 230°F to drive off residual solvent.. After a minimum of twelve hours the extracted samples were removed from the convection oven and cooled to laboratory temperature in a desiccator. Grain Density Determinations Grain volumes were determined by Boyle's Law double-cell methods using an extended range helium porosimeter. Where applicable, metal jacket and end-screen weight and volume corrections were applied. Grain density values were calculated using Equation 1. Mg (1) (~ma = vg Where: 8ma = Matrix (grain) density (g/cc) Grain mass (g) Grain volume (cc) Porosity Determination (Jacketed Samr)les) Direct pore volume measurements also by Boyle's Law double-cell methods were performed upon samples confined at 400 psig in Hassler-type core holders. Porosity values were calculated using Equation 2. (2) Where: Vp Vg = Porosity (%) = Pore volume (cc) = Grain volume (cc) Fluid Saturation Calculations Oil and water saturation results were calculated using Equations 3 and 4. So = (3) Sw = [-~].100 (4) Where: So Sw Mf Md = Oil saturation (%) Mw =. Water saturation (%) Vw = Fresh sample mass (g) §o = Clean, dry sample mass (g) Vp = Water mass (g) = Water volume (cc) = Density of oil = Pore volume (cc) Permeability to Ail; Permeability determinations were made on the jacketed samples following pore volume determinations. Permeability values for the un-jacketed samples were estimated. Permeability values of sleeved samples were calculated utilizing Darcy's Equation for compressible fluids, Equation 5. (5) Where: Ka = vg = AP = p = Qa = L = Vb = Permeability to air (md) Atmospheric pressure Gas viscosity (cp) Differential pressure Mean pressure Flow rate (cc/sec) Length (cm) Bulk volume (cc) Sample Disposition,. Sample plugs to be returned to Phillips Petroleum in Anchorage under separate cover as per Phillips' instructions. '" CORE ANALYSIS RESULTS Phillips Petroleum Co.

Casing Stub Surface I arrived at the rig at 1600 hours to find the crew just starting to trip back in the hole to tag the bottom hole plug. The plug was tagged at 2000 hours at 5700' M.D. This is approximately 404' feet higher than top of shows and isin compliance with 20 AAC 25.112 (1 B). The top of the plug was still slightly soft as was indicated by the tools sticking slightly when picked up. A second tag Was made and 20 K was set down in the same spot as before. The tools picked up somewhat better this time. The samples of the pumped cement showed the lead to be well setup and the tail firm but not solid yet.

The following confirms our discussions with regard to plugging back Atlas #1. You will be increasing the volumes for the cement plugs based on the caliper of the hole at the plug depths. We request that the top of the deep plug be tagged. Please have the rig contact the North Slope Inspector so he may witness this operation. You are not required to tag the intermediate plug. In the next day or so you will be filing the appropriate 403 document for the plug setting. A 401 application will follow shortly for the Atlas #1-A. Good luck and thanks for providing such complete information. Tom Maunder Tom J Bmssfield wrote: > Tom, herea, the plug depths forthe Atlas 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. Annular disposal of drilling waStes will not be approved for this well until sufficient data is submitted to ensure that the requirements of 20 AAC 25.080. are met. Annular disposal of drilling waste will be .'. contingent on obtaining a well cemented surface casing confirmed by a valid Formation Integrity Test (FIT). Cementing records, FIT data, subsequent LOT data following setting production casing, and any CQLs must be submitted to the Commission on form 10-403 prior to the approval of disposal operations. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Blowout prevention equipment (BOPE) must be tested in accordance with 20 'AAc 25.035: Sufficient ' nOtice .(approximately 24 hours) of the diverter function test and initial BOPE test must be given prior to commencing drilling operations 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. ~~Since , ' Daniel T. Seamoun, .

Department of Environmental Conservation w/o encl. To: Torn Brassfield Bill Lloyd From: Wayne Campaign ATO 1454 Subject: Shallow Salinities West ofKRU Area Date: January 26,2001 I have looked at the shallow intervals several wells in this general area for the purpose of estimating connate water salinities. When available, I have employed the techniques of SP and Rwapparent (denoted as Resistivity-Porosity (RP) in the EP A document). Both are well known techniques within the industry. I compare and contrast these results, and discuss the weaknesses of each method and provide a final recommendation for each selected sand. The wells included here are Kalubik #1, ARCO Colville River St. #1, and Cirque 2. All of the wells have sufficient shallow logs though in a few instances, porosity log quality is badly affected by hole washouts. In these cases, porosity had been inferred from the maximum density excurSIOns. An important interpretation is to pick base of permafrost. In the past, a lOO Qm cutoff was used for this pick. I have used another method incorporating the sonic log. The permafrost occurs in unconsolidated sediments where sands freeze while the shales do not. This makes the sands non-conductive and consolidated, while the shales are conductive and unconsolidated. On the sonic log, the frozen sands have low .ð.t but the shales exhibit high values. This shows up as a negative correlation between the shale log (GR) and the sonic. Unfortunately, few wells have sonics in the shallow section and even fewer have sonics in the permafrost. This pick is critical. Attempting to calculate salinities in permafrost with either method would lead to wildly erroneous answers. same is true for sand containing hydrates. Another issue is the shale content of the sands in question. Shaliness will have variable effects of the salinity techniques, depending on the nature of the shale, itself. Mr. Wayne Campaign February 15, 2001 Page 2 The following table is a list of salinity calculations for the sand underneath the permafrost. Calculated fluid resistivities are corrected to 75°F and salinity numbers are in NaC1 equivalent, or Total Dissolved Solids (TDS). Kalubik #1 Rmf= 1.19 fl-m ~ 69° Permafrost @ 1510' II Sand ~ 1740'-90' · =36 Rt= 12rim Rwa = 1.09 (5.3 Kppm) SP = -35 mv (@ 35°) RwSP = 0.38 (15 Kppm) Hole badly washed out. SP probably more representative. Colville River St 1 Rmf= 2.52 fl-m ~ 68° Permafrost ~ 1360' Sand ~ 1510'-20' · =36 Rt=2.1 Rwa -- 0.24 (28 Kppm) SP = -40 mv (@ 34°) RwSP -- 0.5 (20 Kppm) Zone slightly shaly. Salinities quite high. Cirque 2 Rmf= 2.28 fl-m ~ 85° Permafrost ~ 1170' Sand ~ 1440'-60' · = 34 Rt = 26 Rwa = 2.1 (2.5 Kppm) SP = -20 mv (@ 35°) RwSP = 1.03 (5.4 Kppm) Hydrates suspected. SP more representative though still too low. In the Kalubik and Cirque wells, average resisfivities drop dramatically below these sands, indicating much saltier waters. In the Colville well, the high salinifies begin at the base of permafrost. Kalubik Water salinities below permafrost probably in the 10-12 Kppm range (TDS), increasing to 25 Kppm below 1950'. ColviHe River St. 1 Salinities below permafrost are approximately 25 Kppm TDS. Cirque 2 Under permafrost, salinities are 6+ Kppm increasing to 21 Kppm below 2200'. None of the wells exhibit decreased salinity below these depths. If you have questions or comments, feel free to contact me. Wayne Campaign Cc.

This well will be accessed via ice road originating near 2L Pad, drilled using Doyon Rig #141, tested and permanently abandoned prior to spring breakup. Attached is the information required by 20 ACC 25.005 (c) for your review. There are no shallow hazards expected at Atlas #1 (see attached graphs). The nearest offset wells indicate no overpressured intervals or lost circulation zones. There will be no reserve pit for this well. Waste drilling mud will be hauled to a KRU Class II disposal well. If a production casing string is set in this well Phillips requests that Atlas #1 be permitted for annular disposal of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. As in the past Phillips would submit a 10-403 Form to the Commission with the appropriate technical information. All cuttings generated will be either stored temporarily on site or hauled to the Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. If this well is tested, the produced fluids will either be hauled to Kuparuk for recycling or injection into an appropriate disposal well or the produced fluids will be reinjected into the Atlas #1 wellbore. Please note that Phillips does not anticipate the presence of H2S in the formations to be encountered in this well. However, there will be H2S monitoring equipment operating, as is the usual case while drilling wells in and near the Kuparuk River Field. If you have any questions or require any further information, please contact me at 263-4603 or Tom Brassfield at 265-6377. Sincerely, /, .

Employ lightweight permafrost cement lead slurry to assure cement returns to the surface. Adequate excess cement will be pumped to ensure cement reaches the surface during the first stage cement job. NOTE: TAM Port Collar will be placed in the 9-5/8" casing at approx. 1000' TMD below the surface. Port collar will only be opened and used if cement does not cimulate to surface. As an alternative, if observations at surface indicate cement top is above the Port Collar, a top job may be performed in lieu of utilizing the port collar. A Top Job may only be performed after consulting with the AOGCC. This is based on the cement thickening time and time required to trip in the hole and open the Port Collar to perform the second stage cement job. Install and test BOPE to 5,000 psi. Test casing to 2,500 psi. Drill out cement and 20' of new hole. Perform formation integrity test not to exceed 16.0 ppg EMW.

Annular Puml:)inq Operations: Incidental fluids developed from drilling operations will be either injected into the Atlas #1 approved annulus or hauled to the nearest permitted Class II disposal Well. The cement rinsate will not be injected down the dedicated disposal well but will be recycled or held for the Atlas #1 open annulus or injected down another Kuparuk well open annulus.

(,' PRESSURE INFORMATION AND CASING ~E~GN annulus will be filled with diesel after setting production casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. We request that Atlas #1 be permitted for annular pumping of fluids (if production casing is set) occurring as a result of drilling operations, per regulation 20 AAC 25.080. Any zones containing significant hydrocarbons will be isolated prior to initiating annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Reference the enclosed directional drilling plan for other formation markers in this well. Surface casing will be set in the Cretaceous shales below the base of the West Sak Sands. These 300-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow. The surface casing shoe will be set a minimum of 50' vertically below the base of the West Sak into the heart of the shales. The maximum volume of fluids to be pumped down the annulus of this well will not exceed 35,000 bbl without the specific permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling fluid wastes. Using 12.0 ppg fluid and the rig's specified maximum pumping pressure of 1,500 psi for annular injection, the maximum pressure at the surface casing shoe is estimated by: Max Shoe Pressure = (12.0 ppg) * (0.052) * (Surf. Shoe TVD) + 1,500 psi = (12.0 ppg) * (0.052) *.(1808') + 1,500 psi Max Pressure '2629 psi This pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and production casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the casing performance properties above.

Brassfield ATO-1550 From: Subject: Kathy Heinlein ATO-1346 Pre-Drill Seismic Pore Pressure Prediction for Proposed Well Locations: Atlas 1, Atlas 2 Date: December 19, 2000 The purpose of this memo is to report and review the velocity-based pore pressure prediction for the proposed Atlas well locations, Summary Seismic velocity data was used to predict pore pressures likely to be encountered in two proposed well locations. A local compaction trend and a local velocity to pressure gradient translation trend model was established using control from the Cirque #2 offset well. The trends calculated at Cirque #2 were compared to trends observed at Tarn and Meltwater and found to be similar. The local compaction trend and translation trend model established from the existing wells was applied to velocities from 3D seismic inlines, 3D seismic crosslines and 2D seismic to predict pore pressures. The predictions show no apparent shallow hazards or large pressure anomalies at the proposed well locations. Seismic Processina: The accuracy of seismic geopressure analysis depends critically on the accuracy of the input velocity field. The velocities used were generated using Phillips' AVEL program, an automated high-resolution velocity analysis program developed by ARCO Exploration and Production Technology. This process produces a very accurate velocity field defined at every sample in time and laterally along each seismic line. The output RMS velocities were smoothed over 9 CDPs to minimize instabilities in the velocity field that might result from noise, lack of signal or variations in CDP fold. RECEIVED DEC ~ ? ZOO0 Alaska 0il & Gas Cons. Commission Anchorage Pressure Prediction Procedure: The Cirque #2 offset well was used to establish both a local normal compaction trend line and local velocity vs. pressure translation trend model. This model is similar to the regional models used previously at Meltwater and Tarn. Procedure 1 .) Normal Compaction Trend Lines (NCTL) were calculated for a series of seismic lines from the WBA 3D seismic dataset, in addition to three 2D seismic lines. The slope of the individual seismic NCTLs matched the slope calculated at Cirque #2, but the intercepts varied slightly from the Cirque #2 NCTL. This is not unexpected as the seismic velocity measures a larger component of horizontal velocity vs the well sonic log which measures primarily vertical velocity. The NCTL from the 2D seismic data also has a slightly different slope than the 3D NCTL; this is not unexpected, as differences in survey vintage, processing, phase etc can contribute to a difference in intercept. The Cirque #2 NCTL has an intercept of 148; the 3D seismic lines have an average intercept of 155, and the 2D lines have an average intercept of 165. The slope of the NCTL line is -4.5e-5. 2.) The difference between interval transit times (ITT), recorded by wireline sonic logs (z~T) in the existing wells or by seismic velocities in the proposed wells, and the Interval transit times predicted by a downward extension of the NCTL were measured. These values are the travel time differences,/~z~T. 3.) A translation trend model was established by comparing transit time differences (z~z~T) to mud weights. This model calculates pressure gradients (PP) using the equation PP = C2%/~T**2 + C1 *z~z~T + CO Where C2 = -1.34'5, Cl = .0062, CO = .465 4.) Fracture gradients were calculated using the Eaton Method. Inputs are the bulk density, the calculated pore pressure gradient profile, and a Poisson's Ratio profile (from a West Cameron model). RECEIVED DEC ? 000 Alaska Oil & Gas Cons. Commission 'A~rage Cirque #2: Figure #1 is the pore pressure gradient calculation for Cirque #2. The left side is the wireline sonic DT (black curve) with the NCTL (red line). The right side is the pore pressure gradient calculation (blue curve), actual mud weight (green curve), and the calculated fracture gradient (red curve). Casing points, areas of hole problems, formation tops, and lithology changes are as labeled. A thin zone of over-pressured gas-charged sand was encountered in the Cirque #2 well at 2171 ft SSTVD (K-10). Similar shallow gas-bearing zones below the permafrost layer are suspected of causing the blow-out at the Cirque #1 well. Over-pressured free gas may have been encountered in approximately this same interval below permafrost, and additionally gas hydrates may have melted within the permafrost layer as a result of the gas returns from this interval. A false pressure increase is noted at approximately 6532 ft SSTVD. This apparent pressure increase is actually due to a change in lithology which results in slower velocity. Seismic Pore Pressure Prediction (No Shallow Ha_~erds Observed)- Pressure gradients were predicted at each well location from both 2D and 3D seismic velocities (inline and crossline). Although the 3D data allowed exact ties to well locations, the 2D data may provide more accurate velocity fields in the shallow section above 3000 ft. This report includes displays in time and depth of pressure gradient predictions on 3D inlines and 3D crosslines at each Atlas well location, in addition to a 2D seismic line that runs NW -> SE close to both the Atlas and Cirque well locations.

Commission Anchorage Warmer colors indicate higher predicted mud weights (pore pressure gradients). No Shallow Hazards or areas of high pressure at depth were observed, An increase in predicted pressure at approximately 2600 ft SSTVD is observed on the 2D seismic data at the proposed well locations. This apparent increase in pressure is not observed in the 3D data. The 2D and 3D prestack migrated gathers used for velocity analysis were reviewed to determine the accuracy of predicted seismic velocities at the location of the anomaly in depth at both the Cirque and the Atlas well locations. Although the 2D data has a higher effective fold at this depth, it is also contaminated by noise which degrades the velocity calculation. It is not possible to determine from the data available if the increase in pressure noted on the 2D seismic data is the result of poor seismic stacking velocity estimates, due to a lithology effect, or due to a true increase in pressure. Pore Pressure Gradient Prediction at Proposed Well Locations: Figure # Seismic Line Well Name 12 IL 2687 ATLAS 1 13 WG83-42 ATLAS 1 14 IL 2693 ATLAS 2 15 WG83-42 ATLAS 2 Figures 13 and 15 (2D seismic line WG83-42) show a large value for both predicted pressure and predicted fracture gradient above 100 ft SSTVD; this is due to invalid velocity values in the velocity section input to pressure prediction. These values do not affect any of the calculated values at deeper depths. REC'EiVED DEC Alaska Oil & Gas Cons. Commission Anchorage Cirque #2 Well and Seismic Pressure Prediction: Pressure prediction from seismic data was run at the location of Cirque #2 to determine if the thin-zone of over-pressured gas-charged sands observed in the well would be predicted by this method of pressure prediction, and to determine if it was possible to predict the presence of gas hydrates within the permafrost. An increase in pressure is noted on the 2D seismic data at approximately 3000 ft SSTVD (Figure #10). This same increase in pressure is not apparent on the 3D seismic data. The depth of the high- pressure anomaly is deeper than anticipated by the well observations, which place the zone of overpressure at 2171 ft SSTVD. There is no apparent indication of the presence of gas hydrates within the permafrost layer on either the 2D or the 3D seismic data. There is a possibility that gas-charged sands exist in the K-lO interval at the proposed Atlas well locations, and further work is recommended to better understand the pressure response predicted from seismic data at the Cirque #2 well. Conclusions: 1 .) There are no apparent shallow hazards at any of the proposed well locations. 2.) The NCTL and Translational Trend Model calculated at the Cirque #2 well is similar to models calculated at Tarn and Meltwater. 3.) A thin zone of overpressured gas-charged sands was encountered below permafrost at the Cirque #2 well. There is the possibility that gas-charged sands exist in this interval in the vicinity of the proposed Atlas well locations; work is in progress to determine if the predicted pressure response of these sands can be improved using existing seismic data. 4.) Gas hydrates may exist within the permafrost but will not be detected by this method of analysis.
