Box 100360 Anchorage, AK 99510-0360 Re: Requested annular disposal of cement washdown water from Colville Delu exploratory wells Dear:MI. McKay: The Commission has received your request fo.r 'authorization for disposal of cement washdown water from certain Colville Delta exploratory wells in the annuli of wells currently being drilled in the Kuparuk River Unit. The washdown water would be generated by àrilling operations at the following exploratory wells during the 1996 season: Bergschrund #2, Bergschrund #2A, Alpine #3, Nanuk #1, Neve #1, Neve #1A, and Temptation #1. Disposal would take place into the annuli of wells being drilled by Parker Rig #245, for which annular disposal has already been authorized. We understand that cement washdown water is produced as a result of blending and núxing cement used in drilling wells. It therefore appears that the cement washdown water you propose for annular disposal is a nonhazardous waste associated with the act of drilling an oil or gas well for exploratory purposes, witbill the meaning of AS 31.05.030(e)(2). Ordinarily annular disposal is permitted in well annuli located on the same drill pad as the well generating the waste in question. You have explained that the Colville Delta exploratory wells will not bave annuli available for disposal operations. The Commission authorizes ARCa Alaska, Inc., to dispose of cement washdown water from the above-listed Colville Delta exploratory wells in the annuli of wells currently being drilled within the Kuparuk River unit by Parker Rig #245, subject to the existing terms and conditions govemiDg annular disposal in the latter wells. This authorization is for the 1996 drilling season orily. Sincerely, "i0(Út4!.J- ~~clœrman Babcock Commissioner \... J, David Norton, P .E.

V ~as\\3 1...;1 ~ ..')~ .__".:, . þ.J\chC', '<'+'" ARCO hereby requests a waiver to the AOGCC Regulations (20 AAC 25.080.) covering Annular Disposal of Drilling Waste recently adopted by the Commission on January 31, 1996. This waiver is requested to cover ARCO's Colville Delta exploratory wells currently being drilled during the 1996 winter drilling season. Cement washdown water is an integral part of any cement job. Cement is used as a means of pressure control in the wells being drilled. Each casing string, sidetrack plug, P&A plug, and other cement plugs mixed for use in drilling wells produce a relatively small amount of cement washdown water as a result of the cement bienc;ng and mixing operation. We are requesting the Commission determine under 20 AAC 25.080. that this washdown water is a waste associated with the act of drilling a well and permitted for annular disposal. Secondly, ARCO requests permission to transport cement washdown water from the Colville exploratory operations to approved disposal annuli in the Kuparuk River Unit. This waiver is required since cement washdown water is not exempt, and thus cannot be disposed of in Class 2 injection wells in the Kuparuk River Unit. It is also required because the Colville Delta exploratory wells do not have annuli available for annular disposal operations. Normally, the amount of cement washdown water generated for any individual cement job is less than 250 bbls, although it an vary widely depending upon the operation. ARca Alaska, Inc. is a Subsidiary of AtlanticRichfieldCompany ~ ïhe wells generating cement washdown water needing a waiver this winter include: Bergschrund #2 Bergschrund #2A Âipine #3 Nanuk #1 Neve #1 Neve #1 A Temptation #Î The destination of the waste would be the permitted annuli of the wells currently being drilled within the KRU by Parker Rig #245. The cement washdown water would be pumped into the permitted annulus that Parker Rig 245 was connected to at that time. Again, the permitted wel! would be within the Kuparuk River Unit. VVe appreciate your consideration of this request. If you have any questions or require any additional information on this matter, please contact me at 265-6890.

Februarv 25. 1996: I traveled this date to ARCQ's PBU DS 15-48 being drilled by Doyon rig 14 and witnessed the initial BOPE test. - As the attached AOGCC BOPE Test Report shows there were no failures of the equipment tested. The upper and lower kelly valves were not tested because the crew had not picked up the new 3.5" kelly. The floor safety valves will be tested with the kelly valves. This rig drilled this well to the current depth earlier and then suspended operations due to seismic work being done in the area of the pad. I will be notified of the results when the testing is concluded. The rig was fairly clean and all equipment seemed to be in good working order. The location was clean and all extra equipment was stored properly. Summary: I witnessed the BOPE test on Doyon 14 drilling ARCO's DS15-48 - test time 3 hours - no failures.

I. Supervisor ::-\; FROM: Bobby FostØ SUBJECT: P & A Cmt. Plugs Petroleum Inspector ARCa - Exploratory Bergschrund # 2 PTO # 95-0216 Fridav. February 23. 1996: I traveled this date to ARCa's Burgschrund # 2 after being contacted by Donnie Lutrick, ARCa drilling rep., informing me that they were going to suspend operations. Donnie told me that they were going to set 3 cement plugs. I departed for the location and arrived at 5:30PM. The drilling crew was in the process of going in the hole with the DP to the TO of 8,600'. After getting to TO the well was circulated until bottoms up had been attained. The first plug was set from 8,600' to 7,914" ETC. This plug was not tagged. This plug consisted of 282 sks. ( 58 bbls. ) of 15.8 Ib/gal. class G cement. The DP was pulled to 7,000' +- and the hole was circulated and the drilling mud was thinned and treated in order to set the next balanced plug. After treating the mud the DP was run in the hole to 7,600' and a 20 bbl. hi-vis weighted (10.2Ib/gal.) pill was pumped. The DP was pulled to 7,350' and the second plug consisting of 260 sks. ( 53 bbls) of 15.6 Ib/gal. cement was pumped. The DP was pulled out of the hole and a drill bit was picked up and the OP was run back in the hole to 4,000' and then we WOCfor 9 hours. At this time the OP was run in the hole and the cement plug was tagged at 6,645' with 20,000 Ibs. of DP weight with the mud pumps running at a rate of 2.5 bbls/min. After tagging the plug I departed the location and returned to Deadhorse. Summary: I witnessed the setting and tag of the "suspend operations" cement plugs set on Arco's Bergschaurd # 2.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Re: Sundry Notice to Plug Back and Shutdown Operations ARCO Bergschrund #2 Permit No. 95-216 Dear Commissioner Johnston, The ARCO Bergschrund #2 well has been drilled to 8600' MD (7354' TVD) and plans are being made to plug the well back to the 9-5/8" surface casing at 1827'. After plugging the well back to the surface casing, ARCO plans to shutdown operations on the Bergschrund #2 well and move the rig to the Alpine #3 well, After drilling Alpine #3 ARCO may move the rig back to Bergschrund #2 to drill a sidetrack. If it was decided not to drill the Bergschrund #2A sidetrack, the well would be plugged and abandoned without the rig. ARCO Alaska, Inc. hereby applies for sundry approval with a variance to plug back and shutdown operations on the ARCO Bergschrund #2, permit number 95-216. A detailed plug and abandonment procedure is enclosed. ARCO requests a variance to the requirements of 20 AAC 25.105 (1) for the cement plug #1 placed as shown at total depth on the attached diagram. ARCO proposes to place plug #1 in the well per 20 AAC 25.105 (f1) using 25% excess cement volume without recording the actual location or integrity. Plug #1 at total depth will be placed on the bottom of the hole which will prevent any chance of the cement falling downhole. High viscosity mud will be placed below plugs 2 and 3 to prevent the cement from falling downhole. A wellbore schematic is attached which depicts the secure shutdown status of the well. The tubing head, tubing hanger with back pressure valve, and lower tree valve will be installed on the well. The 9-5/8" surface casing will be freeze protected with diesel. If you have questions or require additional information, please contact Tom McKay at 265-6890, Fred Johnson at 265-1492, or myself at 265-6206 in our Anchorage office.

The AOGCC test report is attached for reference. The test went quite well with no failures observed. The diverter vent line is routed to take good advantage of the prevailing wind direction. As noted on the test report the vent line is 16" in diameter and is 100'+ from the exterior of the rig and well in excess of 100' from an ignition source. Doyon has recently completed a very extensive upgrade on this rig and all components appear to in very good working order.

The AOGCC test report is attached for reference. As noted in the test report 3 failures were observed, the manual kill line valve on the mud cross was replaced, a leak downstream of the chokes was tightened and the IBOP leaked at the bonnett seal. A new seal was not readily available at the rig, a new seal was enroute from Prudhoe when I departed the location. Doyon was allowed 24 hours to have the IBOP repaired and re-tested and call the AOGCC N.S. office, this was done. The area around the rig is well laid out and all support equipment is well staged.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Re: Revised Application for Permit To Drill ARCO Bergschrund #2 Permit No. 95-216 (Approved 1/12/96) API No. 103-20232 Dear Commissioner Johnston, Attached is a revised Application for Permit to Drill for the ARCa Bergschrund #2. The original Permit to Drill Bergschrund #2 was approved 1/12/96. Since that time, the surface location of this directional well has been moved 250' to the west of the original location to 964' FNL, 1370' FWL, Sec 9, T11N, R5E, UM. The surface location was moved due the uneven terrain found at the original location which would have made the ice pad building nlore difficult. The planned target location has been moved approximately 2000' to the northeast for geological reasons. This location move puts the target and bottom hole location in a different Lease than shown on the original Permit and results in a different directional plan, but does not change any of the drilling plans or rig information as presented in the original Permit to Drill application. Attached to this Application are a new property nlap and directional drilling plan. All other required infoT1113tion is as presented in the origi~l Application for Permit to Drill. The TD of this well will be at the base of the Nuiqsut Formation which directly underlies the Kuparuk Formation. H2S has not been encountered in this region in any stratum shallower than the Lisburne Formation. Therefore, ARCa has not included an H2S contingency plan with this Application and requests an exemption from the illS requirements. However, all drilling mud, cores and produced fluids exiting the wellbore will be monitored for detectable levels of H2S. ARCO also requests an exception to the shale density requirement in 20 AAC 25.033(e,2,D). The shale density technique does not work well in Alaska due to the variable composition of the shales and the chemical used in the shale density COIUnlI1 is listed as an exceptional health hazard. The ice road to the Bergschrund location is completed and the Doyon Rig 141 should begin mobilization in a few days. Esimated spud date is Febnlary 5.

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. Exception to diverter variance 20 AAC 25.035(b)(1) is approved. BloVvQut 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. (--~:S-~~;:;ìrury. ~~_ ... "--->::>:~:>.-, > .

Following are the major concerns associated with this request. 1) After extensive study of the 1992 Cirque blowout and the performance of the equipment on Cirque, ARCa Alaska, Inc. has determined that a combination of one 16" line with no 90° turns is the optimum design. 2) Effective operation of remote valves positioned 100 feet from the rig are limited. 3) Prevailing winds on the North Slope during the winter drilling season are generally in the direction of NE to SW. With perpendicular placement of the diverter line, there is minimum exposure of gas blowing back onto an ignition source. It is our opinion that with proper placement of the diverter line with respect to prevailing winds in conjunction with the short duration of time while drilling under the diverter, a bifurcated line is not necessary.

Proposed Mud Program Bergschrund #2 (Colville Exploration) November 20, 1995 General Well Plan: A standard Kuparuk type fresh water spud mud (10.0 ppg) will be used to the 9 5/8" casing point. From there to TD, a fresh water LSND system similar to that used on last winter's Alpine and Fiord tests will be used to drill the 8 1/2" hole. The plan is to treat the fresh water spud mud for cement contamination when drilling out of the 9 5/8" surface shoe and drill ahead in the 8 1/2" hole to TD treating the system as a standard fresh water LSND system. However, as dictated by the actual drilling requirements of this well, an inhibited mud (KCl) may be required to address special coring or formation damage issues. --------------------------------------------------------------------------- Estimated Casing Program: Hole Size 20" 12 1/4" 8 1/2" Casing Size Conductor 9 5/8" 7" --------------------------------------------------------------------------- I. Surface Hole (12 1/4" Hole to 9 5/8" Casing): 1.) The current plan is to have 800 bbls of 10.0 ppg spud mud at the Baroid Prudhoe Bay Mud Plant to spud this well. The mud will be delivered to the rig with the following target properties: Density Viscosity YP pH 10.0 ppg 120 sec/qt 35-40 Ibs/100ft(2) 9.0-9.5 To drill ahead, maintain the viscosity at initial levels to the base of the permafrost (800'-1000') then reduce the viscosity as allowed based upon actual hole cleaning requirements. A funnel viscosity of 50 - 80 sec/qt may be suitable by the 12 1/4" TD. It should be noted that the actual mud viscosity requirements will vary in this area based upon the actual amount of surface gravel present at each specific location. However, generally only minimum gravel has been noted in this area allowing successful drilling with reduced viscosities. 2.) Due to concerns for gas below the permafrost and to reduce barite mixing activities during spud operations, spud the well with a 10.0 ppg mud weight and basically hold that mud weight to TD of the 12 1/4" surface hole at 1800'. While there is some mud weight latitude from spud to the base of the permafrost at 800'-1000', the mud weight should be a solid 10.0 ppg by the base of the permafrost then held at that weight to the 12 1/4" TD (or as dictated by actual hole conditions). 3.) PAC treatments can be initiated toward the 12 1/4" TD for improved well bore stabilization by reducing the API filtrate to 8-10 ce's. paqe - 1 3.) Maximize all solids control efforts. Run as fine as screens possible on the shale shakers. The use of the rig's desander, desilters/mud cleaners and centrifuge should be based upon daily mud solids analysis versus the current mud objectives. With a weighted mud from spud to TD (10.0 ppg+), the application of the various pieces of solids control equipment will change based upon the changing condition of the mud itself. 4.) Treatments with PAC polymers should be used throughout this section of the hole to control the API filtrate in the 6 to 8 cc range or as required based upon actual well bore conditions. Low viscosity or regular viscosity PAC products are available for use. 5.) Control excessive rheological conditions with additional Therma-Thin treatments on an as needed basis. Therma-Thin is an effective polymer deflocculant designed to provide effective rheological stabilization. By maintaining a .25-.5 ppb concentration of Therma-Thin in all make-up additions, better rheological stability will be observed. 6.) The commercial bentonite (Aquagel) concentration should be kept at 2-4 ppb minimum through this intermediate section of hole. 7.) Dilute as necessary and maintain volume with fresh water as required. 8.) Maintain the pH in the 8.5 - 9.0 range with caustic soda additions. 9.) Torq-Trim II or ConDet treatments may be required to reduce balling problems through the "sticky" clays found in this interval of the well. 10.) Continue with tourly treatments of Aldicide-G while drilling this interval of the well. A 5-10 gal/tour treatment rate has proven effective in recent North Slope work. --------------------------------------------------------------------------- III. 8 1/2" Hole (From of Top Zone of Interest to TD): 1.) Prior to drilling into the zone of interest, the mud should be conditioned as follows to insure mud stability and to reduce the API filtrate for pay-zone protection. One should expect a minimum dilution of 10-15% with fresh water to re-adjust total solids and to make the system receptive to the following treatments: A. Run the pH in the range of 8.5-9.5 with caustic soda. B. The API filtrate should be reduced to the 4-5 cc range with Baranex and PAC's at a 3 : 1 ratio. This will probably require approximately 3 ppb Baranex and .5-1.0 ppb PAC's. Target a HTHP filtrate of 15 cc's at 200 degrees. C. Be aggressive with biocide (Aldacide-G) treatments to reduce/minimize bacterial degradation. A field kit is available to monitor the residual biocide concentration. D. Continue with fresh water dilution as required to adjust the total solids content of the mud. Page - 3 E. Adjust the mud weight as required with Baroid (barite). The anticipated mud weights for this interval of the well is between 10.0 and 11.0 ppg. 2.) To control excessive rheology, treat as required with Therma-Thin (a polymer deflocculant) and/or Desco CF (tannin powder). 3.) At TD, conditioned for logs and possibly a 7" casing job. Primary focus should be on rheological stabilization with caustic treatments for pH control and Desco-CF, Therma-Thin and/or Enviro-Thin thinners to control excessive rheological trends. --------------------------------------------------------------------------- IV.

Yo vV11 trllSSlon Anchorage Pore Pressure Prediction for the Bergschrund #2 Well (WKE95-30) correlated to the Alpine #1 Well. The following summarizes the pore pressure work done in the Colville area using the above data. The wireline sonic data was used to predict the pressure in the Alpine #1 well; and the seismic velocity was used for the seismic line. There are no large pressure anomalies at this well or seismic line. 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 every CDP location with an automated high resolution velocity analysis program (URCI process developed by ARCO Exploration and Production Technology). This process produces a very accurate and densely sampled velocity field to cover every 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 pore pressures. These were the steps taken to calculate the pressures: 1) The Gamma Ray log from the Alpine #1 well was used to distinguish the sand intervals from the shales. 2) A Normal Compaction Trend Line (NCTL) was determined in the shales from the wireline sonic data for the Alpine #1. This line indicates the predicted sonic value if these shales were normally compacted (no pressure). If the sonic delta T increases past the compaction line, (this change is ~~ T), then there is an indication of an increase in pressure. 3) Using the mud weight data from the Alpine #1 and Bergschrund #1 wells, a Translational Trend model was developed to convert the /1/1 T to equivalent mud weight (PP). This equation is : PP = C2 * /1/1 T 2 + C1 * /1/1 T + Co where C2 = -1.34 e -05; C1 = .0062; Co = .465 4) This NCTL and Translational Trend was used for the seismic line. Alpine #1 Figure #1 is the pore pressure plot from the wireline sonic data. The curves from left to right are: 1) The black curve is the sonic log. The green dots are the shale intervals. 2) The red line is the Normal Compaction Trend Line. 3) The blue curve is the pore pressure. 4) The green curve is the actual drilling mud weights. 5) The red curve is the fracture gradient. 6) The points labeled "pressure" are RFT measured pressures in equivalent mud weight. 7) "LOT" is the leak off test in equivalent mud weight. There are no major pressure intervals in this well. There are some minor ones at 2000' and 3800' where the mud weights may need to be increased to 10 ppg. At 6800', there is an increase in the sonic ðT which is attributed to the kerogen in the shales. This can be seen on the Gamma Ray increase on the logs. Since there was only one leak off test, it was difficult to create a fracture gradient curve. A Gulf of Mexico trend curve was used in this model and appears to be pessimistic. WKE95-30 (Bergschrund #2 Surface Location) Figure #2 ties the wireline data (black curve) from the Alpine #1 (CDP 2712) to the seismic travel time (red curve, ITT). The green line is the NCTL. The data matches well at 2000'. Figure #3 shows the ITT at CDP 2350 is close to the NCTL at 2000'. Figure #4 shows there is no pressure to 7900'. The pressure deeper than 7900' 111ay be due to the kerogen in the shales or lithology changes. Figure #5 is the pore pressure plots over the seismic interval verses depth and Figure #6 is verses time.

Minor drill gas and hole sloughing should be expected at the base of the permafrost. Base of permafrost is expected at ±900' RKB. Production Hole · Mud weight should be 9.8-10.0 Ib/gal prior to drilling the C-30/K5 interval at 2380'. This interval in offset wells contains gas that is thought to be slightly pressured at 9.6 Ib/gal. · Normal drilling precautions should be taken throughout the hole. RECEIVt::U DEC 2 8 1995 Alaska Oil & Gas Cons. Commission Anchorage ,~ Bergschrund #2 : General Drilling Procedure Application for Permit to Drill December, 1995 (All depths are measu red from RKB unless otherwise noted) o Move in rig and rig up over pre-installed 16" conductor and cellar. o Nipple up and function test diverter. Rig up mudloggers. o Make up 12-1/4" bit and bottom-hole assembly and drill vertical surface hole to 1 ,800' RKB. o Run and cement 9-5/8" surface casing. ° Nipple down diverter, make up casing head, nipple up and test BOP to 3000 psi. ° Pressure test 9-5/8" casing to 2500 psi. ° Drill out cement and float equipment with 8-1/2" bit. Drill 1 0' of new hole and perform leak-off test. POOH. ° Make up 8-1/2" bit and directional bottom-hole assembly with MWD/L WD(GR-Res). Kick off and build angle at 3°/1 DO' to 52°. Directionally drill 8-1/2" hole to ±10,913' MD, 7890' TVD. o If log results are favorable, run and cement 7" casing. o Nipple down BOP stack, nipple up tubing head, nipple UP and test BOP stack~ RECEIVt:u Run cased hole logs. o o Pressure test 7" casing to 3,500 psi. DEC 2 8 1995 o Alaska Oil & Gas Cons. Commission Anchorage Run in hole with completion-type test string, space out and land tubing hanger. Freeze protect 9-5/8" X 7" casing annulus. o o Nipple up and pressure test 5,000 psi tree, tool string and manifold. ° Perforate well underbalanced using tubing-conveyed guns. Flow up the tubing and through surface testing facilities. Test liquids will be stored in tanks on the drilling location and pumped back into the reservoir or hauled to Kuparuk and processed through Kuparuk facilities.. Gas will be flared. Testing will involve alternating flow periods and sh ut-in periods. Individual intervals may be tested separately or concurrently. For long-term flow testing, the rig will be moved off location prior to perforating and will be moved to a different, but nearby, drilling location. ° After completion of testing, abandon well per AOGCC regs. o Rig down and release drilling rig. Thoroughly clean and abandon the ice pad and ice road on the way out.

ARCa plans to use Doyon Drilling Rig #141 to drill this well from an ice pad during the winter of 1995-96.·- Attached find the infonnation required by 20 AAC 2S.00S(c) and 20 AAC 25.061. All waste drilling mud and cuttings generated during the drilling of Bergschrund #2 will be hauled to either the Kuparuk River Field or Prudhoe Bay Field for temporary storage and eventual processing for injection down an approved disposal well. -----.--- The TD of this well will be at the base of the Nuiqsut Formation which directly underlies the Kuparuk FOffi1ation. H2S has not been encountered in this region in any stratum shallower than the Lisburne Formation. Therefore, ARCO has not included an H2S contingency plan with this Application and requests an exemption from the illS requirements. However, all drilling mud, cores and produced fluids exiting the well bore will be monitored for detectable levels of H2S. ARCO also _ _ .-;:¿ requests an exception to the shale density requirement in 20 AAC 25.033(e,2,D). "I¡~, 'ì\t,l~ The shale density technique does not work well in Alaska due to the variable . composition of the shales and the chen1ical used in the shale density column is listed as an exceptional health hazard.
