As development of the CD2 area has progressed, we've determined the present bottom hole location may not be the optimum over field life, and are now contemplating a sidetrack to a different BHL. We still anticipate the sidetracked well will be used in injection service. CD2 has not yet been placed on production or injection. Until the CD2-35 sidetrack plans are finalized, we wish to maintain the ability to place the well in production service. Please disregard our 6-19-00 application for change of service. We will submit an application to sidetrack this well once our drilling plans are finalized. If you have any questions, please call me at 265-6842. Sincerely, Cliff~d L. Crabtree, P.E.

Downhole data is from HES memory gauge #10220 at 8624 ft RKB. Gas and liquid flowrates are calculated from cummulative volumes measured in the separator and tank dudng actual fluid recovery times. Cummulatives are only the volumes flowed thru the separator and to the production line at each rate. Gas gravity was ,804 (by HES Ranarex gas gravitometer). Oil gravity was 40.4° APl @ 60° F.

Report #3 which is the third edition released in August of 1992. The method of calculating the supercompressibility factor has also been updated with the second edition of A.G.A Report #8 released in November of 1992. The supercompressibility factor (Fpv) is directly related to the z factor as it is equal to the square root of l/z. Both of these reports were developed with the cooperation of, or have met the approval of the following agencies: American Petroleum Institute, APl Gas Processors Association, GPA American National Standards Institute, ANSI Changes in Basic Flow Equation Based on a number of recent studies the form of the basic flow equation, used to calculate flow rate through concentric, square edged, flange tapped orifice meters, has changed. The previous form of the equation was as follows: Qg: 96 * Fb * Fr * Y * Fpb * Ftb * Ftf * Fgr * Fpv * Sqrt(hw * Pr) Where: Qg = Fb = Fr = Y = Fpb = Ftb= Ftf = Fgr = Fpv = hw - Pf = Gas flow rate, standard ft3/day Basic orifice factor Reynolds number factor Expansion factor Pressure base factor Temperature base factor Flowing temperature factor Real gas relative density factor Supercompressibility factor Orifice differential pressure, in. of water Static pressure, psia The new form of the equation is as follows: Qg = 24 * Fn(Fc+Fsl) * Y * Fpb * Ftb * Ftf * Fgr * Fpv * Sqrt(hw * Pf) Where: Fn = Numeric conversion factor Fc = Orifice calculation factor Fsi = Orifice slope factor The product Fn(Fc + Fsi) is a replacement for the product of Fb and Fr previously used. The remaining factors were unchanged. It is important to note that calculating the orifice slope factor, Fsi is an iterative process, best accomplished with a computer. Please note that all gas flow rates reported in this report have been corrected for CO2 and H2S concentrations. Also, static pressure is measured at the downstream taps of the Daniels Orifice Meter.

REMARKS AND OTHER OPERATIONS * All pressure and temperature data are taken from the last points of each period. * Downhole data is from HES memory gauge #10220 at 8264 ft RKB. * Gas and liquid flowrates are calculated from cummulative volumes measured in the separator and tank during actual fluid recovery times, * Cummulatives are only the volumes flowed thru the separator and to the production line at each rate, * Gas gravity was ,804 (by HES Ranarex gas gravitometer). Oil gravity was 40.4° APl @ 60° F. All gravities measured at the separator, * CO2 average was 0.5% (by Draeger tube) and H2S average was 0 ppm (by Draeger tube) as measured at the separator by HES.

This request is necessary to expedite clean up of the location and suspension of well operations after well testing is complete. This will minimize the amount of truck traffic required on the Alpine ice road and should minimize the potential for spills. Testing could begin as early as April 11, 1998 and injection operations could begin as early as April 17,1998. Your attention in this matter is appreciated. If you have any questions or require further information, please contact me at 263-4792.

We started with the choke manifold and found a leaking needle valve on the test pump. Then 2 v_aives on the choke manifold leaked so they serviced all the valves on the choke manifold. We found that the first accumulator recharge time was slower than normal but with in acceptable limits. After cleaning the pump suction strainer, the accumulator recharge time was back to aT-most normal. They are going to run the hydraulic oil thru a portable filter to clean impurities out of the oil.

Tile 'primary objective of this delineation well was drilling the Alpine sands horizontally lying in a positive structure on the C~)lville Delta, along with the K2 sand. Drilling progressed with only minor difficulties with some hole swelling due to clays precipitating onto the wall cake. The permafrost ended at approximately 700', with no gas hydrates detected. The decision was made to T.D. the well at 8:50pm, Apdl 3, 1998 at a depth of 11,984' (7122' TVD). (FID) gas detection and two geologist Rigwatch/RigtraldDML mudlogging services commenced on March 13, 1998 at 139' to T.D. above the Alpine Sand. Several significant oil and gas shows were observed in this we31 and are briefly summarized below. The first significant shows were observed within the K-2 sand-from 4615'-to 4680:. Strong oil indicators and heavy C-5 chromatography readings were observed at the top. This sand was saturated to patchy with oil, had a strong petroleum odor, left free oil in the ddlling mud, gave a bright yellowgreen fluorescence, immediate streaming bright wispy yellowgreen cut, and left a moderate yellow residual ring fluorescence. This zone could maybe be economic. The Alpine sand from ~:JO35"to-T13T5' s-howed-a de-finite fining upward sequence, These sands were saturated with oil, had a strong petroleum odor, left free oil in the drilling mud, gave a bright yellowgre~n fluorescence, immediate streaming milky bdght yellowgreen cut, and left a moderate to bright-yellow residual dng fluorescence. The lower lobe was definitely tighter, with a noticeable drop in resistivity. The coarser grained section at the bottom of the upper lobe (Alpine C) appeared to have the best porosity, although some of the finer grained sands above had a higher resistivity (30ohms+). We were asked to check for glauconite percentages on this well. The amount, of glauconite observed was much less than expected, comparing this well with other wells in the area. The only section where abundant glauconite was observed was at the very top of the upper sand lobe, where up to 30% coarse grained glauconite was observed. One thing-interesting phenomenon was observed. The presence of the KCL mud definitely caused @n increase in-The amoun'tO~gas~e]ec'tea comparea-to U~ng other types drilling mud. This ~'as assumed to be happening due to the rheology of the mud. It encapsulated the gas and woul~ not break out of the mud unless highly stirred. Measurement taken above the "possum belly" showed not neady as much gas as when taken directly from out gas agitator. Our gas detection equipment was calibrated numerous times to support the gas readings. It appears to act similarly to oil-base drilling mud when it comes to gas detection. That is, a more effective way of monitoring j[as'kic'ks is throug~h't'he c~r~n~easurement ofYne mt~ way, along with PVT measurements, can a kick be dejected. Overall, I would gauge'the Alpine sands and a long horizontal section was drilled. MUD RECORD ALASKA, INC.

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 about a mile 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. CD2-35 APD 02/23/98 PRESSURE ANALYSIS AND PREDICTION ALPINE FIELD CD2-35 (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 CD2-35 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 gl & #2, Alpine gl & #3, Neve gl, Fiord #3 and Nechelik gl. Pore pressure, fracture gradient and anticipated mud weight graph. Pore Pressure Prediction information required by 20 ACC 25.005 (c) (8). The enclosed report contains data for two different locations. The information pertinent to the CD2-35 well is described as the Alpine Pad. The CD2 drill site at one time was named within ARCO as the Alpine Pad because of its closeness to the Alpine #1 well. Since that time, the naming and numbering scheme has been finalized, and the official designation will be CD2 standing for Colville Drillsite number 2. 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-Dl139 Telephone: To: 265-6465 D. Gingrich J. Trantham ATO-1458 This letter is to summarize the pore pressure work done for the Alpine / Bergschrund area. From the 3-D seismic data, there was a seismic anomaly at the permafrost interface. This anomaly is due to seismic processing and not pressure. Therefore, no pressure is expected for these pads. The slope ( 4.5~ ) and intercept ( 180 ) for the normal compaction pore pressure trend was determined from the Alpine #1 and the Bergschrund #1, There were only ten seismic velocities available for each line. This is the reason for the CDP number scale of 1 to 10. Figure ~ is the pore pressure prediction across the seismic line for the Bergschnmd Pad. Figure #2 shows the comparison of the wireline sonic DT (black curve ) and the seismic tit (red curve) at the Bergschn~d #1. The pressure anomaly from the seismic at 2,250' does not appear on the DT log. This ITT anomaly is due to seismic processing. Figure//~ is the pore pressure prediction for the Be~gschnmd Pad. The anomaly at 1,800' is due to the seismic velocity processing as shown in figure ~2. No shallow pressure is expected for this well Figure #4 is the pore pressure prediction across the seismic line for the Alpine Pad. A comparison of DT and tit was'not made since the wireline sonic DT began at a deeper depth (2,000') than the anomaly ( 1,800' ). No problems were encountered in Alpine #i. This anomaly is due to seismic processing. Figttte #5 is the pore pressure prediction for the Alpine Pad. The anomaly at 1,800' is due to seismic processing. No shallow pressure is expected in this well. Summary: 1) No shallow pressure is expected for the Bergschnmd and Alpine Pads. 2) The seismic anomalies at 1,800' to 2,250' ate due to seismic processing issues.

Production Casing @ 90 deg Liner ANNULAR PUMPING OPERATIONS ALPINE FIELD CD2-35 Incidental fluids from drilling operations will be pumped down the CD1-22 annulus (pending approval) or the nearest dedicated disposal well (1R-18 in KRU) until such time as the intermediate casing is set and cemented. (Note that cement rinseate will not be injected down the dedicated disposal well, but will be recycled or held for an open annulus). The 9 5/8" x 7" annulus will be left with a non-freezing fluid during any extended shut down in pumping operations. The CD2-35 surface/intermediate casing annulus will be filled with diesel after setting the intermediate casing. If isolation is required per regulations on significant hydrocarbons and the surface shoe is within 200' TVD of the top of the hydrocarbon, the annulus will be sealed with cement from the surface shoe to the base of the permafrost, with Arctic pack fluid or diesel. If the hydrocarbons are far below the shoe, then sufficient cement volume will be pumped during the production cement job to cover the formation. It is requested that CD2-35 be pennitted for annular pumping occurring as a result of drilling operations, per regulations 20 ACC 25.080. Any zones containing significant hydrocarbons will be isolated prior to initiating any annular pumping. There will be no USDW's open below the shoe or potable/industrial water wells within one mile of the receiving zone. Please reference the enclosed directional plan for other formation markers in this well. There are no publicly recorded wells within ¼ mile of the disposal operation at this time. Surface casing will be set in the Cretaceous mudstones of the Seabee Formation of the Colville Group. Approximately 1200 feet separates the overlying West Sak sands from the surface casing shoe. The 1200' thick shales of the Colville Group are known to provide vertical isolation to fluid flow. The surface casing shoe will be set +/- 100' vertically below a significant decrease in mudstone porosity, indicating an increase in consolidation. The maximum volume of fluids pumped down the annulus of this well will not exceed 35,000 barrels without specified permission of the AOGCC. Fluid densities will range from diesel to a maximum of 12.0 ppg for drilling wastes. Using 12 ppg fluid and the rig's specified maximum pumping pressure of 1500 psi, the maximum pressure at the surface casing shoe is estimated by: Max shoe pressure = 12.0ppg * 0.052 * surf Shoe depth + 1500psi Max pressure = 3434 psi The surface and intermediate casing strings exposed to the annular pumping operations are determined to have sufficient strength by using 85% collapse and burst ratings as listed below.

The well is designed to penetrate the Alpine formation. Upon completion, the well will be suspended until Alpine plant start-up. Attached, find the information required by 20 ACC 25.005 (c) for your review. Other pertinent information attached to this application is confidential data including the following: 1) Pressure information as required by 20 ACC 25.035 (d)(2). 2) Prediction of overpressured strata as required by 20 ACC 25.033 (e). 3) Seismic refraction and reflection analysis as required by 20 ACC 25.061 (a). 4) Annulus pumping request as required by 20 ACC 25.080. There are no shallow hazards expected at CD2-35, such as shallow gas. There have been five wells drilled in the Alpine field and shallow gas has not been encountered. Please note, ARCO 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 the Alpine field.

Dear Mr. Zanghi' \Vt have rcvicxved ARCO's letters dated January 27 and 30. 1998. as supplemented by .','our Fcbruap,' 9 Icttcr. for a waiver to 20 AAC 25.080(d)(4). The waiver would allow ARCO to dispose of cement rmsatc from Alpine C Pool #6) and Kalubik (Doyon #141) cxploratoQ' wells doxxn the 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 do',vn the annulus of well CD1-22 after it is drilled and meets annular disposal criteria. Ccmcnt rinsatc is gencratcd from washing ccment-mixing cquipmcnt after ccmcnting 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 does not bc'licve it is prudent to usc Pad 3 for disposing ofccment rinsatc. As the principle Class l t'acilitv on the North Slope. Pad 3 handles non-hazardous, industrial oil,,' wastes. The limitcd capacity of Pad 3 should not bc squandcred in processing cemcnt rinsatc. which is essentially water. The commission concludes that cement rinsate from Alpine and Kalubik exploratory wclls ma_,,' be transportcd to Parkcr//245 for disposal, or alternatively to CD 1-22 aftcr mccting disposal critcria. This approval is for thc following wells. Alpine area Kalubik area CD 1-22 Kalubik//2 Nuiqsuit # 1 Kalubik #3 Nuiqsuit # 1A C ._ David \V. John~n Chairman Notice of Public Hearing STATE OF ALASKA Alaska Oil and Gas Conservation Commission Re: Alpine CD2-35 delineation oil well. ARCO Alaska, Inc. by letter dated February 24, 1998, has requested an exception to the provisions of 20 AAC 25.055(a)(3) for the drilling of a delineation oil well due west of the Kuparuk River Unit and adjacent to the eastern boundary of the National Petroleum Reserve, Alaska (NPR-A) on the North Slope. The exception would allow ARCO to drill the Alpine CD2-35 delineation oil well to a bottom-hole location that is closer than 500 feet from a quarter section line. The well will be drilled as a directional hole from a surface location 1914' from the north line (FNL) and 1520' from the east line (FEL) of Section 2, T11N, R4E, Umiat Meridian (UM) to a bottomhole location 1929' FNL and 366' FEL of Section 12, T11N, R4E, A person xvho may be harmed if the requested order is issued may file a written protest prior to 4:00 PM March 12, 1998, with the Alaska Oil and Gas Conservation Commission, 3001 Porcupine Drive, Anchorage, Alaska 99501, and request a hearing on the matter.
