Crandall Alaska Oil & Gas Conservation Commission 3001 Porcupirze Drive Anchorage, AK 99501 Subject: ARCO/BP/UTP Till # 1 well ,o4 Dear Bob: This letter is to explain the lack of a wireline resistivity log in the ARCO/BP/UTP Till # 1 well. The resistivity .log, in this case a DLL, failed in the interval between surface casing (2036' md) and TD (6975' md). Because of the high quality and accuracy of Sperry-Sun's 'Phase 4' MWD resistivity device, which had already been acquired, no additional attempt was made to acquire wireline resistivity data after the tool failure. AAI has sent you a tape in LDWG format which contains the MWD resistivity curves merged with all other log data, as well as sepias blueline plots of the MWD log. Sincerely, Douglas S.

TABLE OF CONTENTS Section 1 2 3 SIDEWALL CORE ANALYSIS, SERVICE DESCRIPTION SIDEWALL CORE ANALYSIS, TABULAR RESULTS TRANSMITTALS SECTION 1 SERVICE DESCRIPTION Sidewall Core Processing in Anchorage Sample Preparation Core Laboratories was not represented at the wellsite. Seventeen rotary sidewall cores were picked up at ARCO by Core Lab personnel March 15, 1993. Upon arrival at Core Laboratories' Anchorage facility, the sidewalls were removed from their jars, cleaned of drilling mud a cut into right cylinders. The samples were immediately loaded into Dean-Stark apparatuses. Sidewall Analysis Techniques Dean-Stark Fluid Saturation Measurements Water was extracted from the samples by Dean-Stark technique using toluene. Samples were left in the Dean Stark for 24 hours. Recovered waters were measured, and the samples were placed in a Dean Stark with chloroform for hydrocarbon extraction for a minimum of 48 hours. Extracted samples were dried in a convection oven at 240 degrees F. for a minimum of 24 hours, and cooled in a desiccator to room temperature before porosity and permeability were measured. Saturations by Dean-Stark methods were calculated using Equations I and 2. So = [((W1 - W2 - H20)/Do)/Vp] x 100 (1) Sw = [H20/Vp] x 100 (2) Where: So = Oil Saturations, Percent Sw -- Water Saturation, Percent W1 -- Natural Weight W2 = Extracted and Dried Weight H20 = Extracted Water, Density Assumed 1.0 gm/cc Do = Density of Oil Vp = Pore Volume Grain Density Grain volume determinations were measured on all samples according to Boyle's Law utilizing the Extended Range Helium Porosimeter. The equipment was calibrated to yield a grain density variation of less than .005 gm/cc. Grain densities were calculated using Equation 3. Where: Dg : Mg/Vg Dg : Grain Density Vg : Grain Volume Mg : Grain Mass (3) Atmospheric Porosity The horizontal plug samples were measured for bulk volume by mercury or displacement at ambient conditions. Porosity was calculated using Equation 4. P : [(Vb-Vg)/Vb)] x 100 (4) Where: P : Porosity, Percent Vb : Bulk Volume Vg : Grain Volume Atmospheric Permeability to Air Horizontal permeabilities were measured in a Hassler type core holder at a confining pressure of 400 psig after the plugs were cleaned in a sonic cleaner and redried. Permeability calculations were performed as defined by Darcy's Equation for compressible fluids, Equation 5. Where: Pa x v x 1000 Qa x L x L K: x (5) (P1 - P2)(P1 +P2) Vb K: Permeabi l ity v : Gas Viscosity P1 - P2 : Differential Pressure P1 +P2 2 = Mean Pressure Pa : Atmospheric Pressure Qa = F1 ow Rate L = Length Vb = Bulk Volume Sample Disposition The sidewall samples are currently at Core Laboratories, and will be transported to ARCO's Bayvi. ew Facility at our earliest convenience. ,- ] I ] i I !

Wednesday March 3, 1993: I traveled this date from AAI's JIU Jones Island to Till No. 1 well to witness the BOPE test on Parker Rig No. 141. On the initial pressure test the Uniclamp connection on the stack choke lined failed, requiring that the connection be cut from the line, and a replacement installed. This operation delayed the BOPE test for 12 hours. Thursday March 4, 1993: The testing commenced this date at 7:00 a.m. and was concluded at 11:00 a.m.. As the attached AOGCC BOPE Test Report indicates, with the exception of a leaking APl ring, on the casing spool upper flange, and a control line fitting on the Upper Pipe Rams, there were no other failures. All personnel were very professional and knowledgeable about the equipment and test procedure. IN SUMMARY, I witnessed the BOPE Test at Parker Rig No. 141, test time was 5 hours, there were 3 Failures, and 22 valves tested, at AArs Till No. 1 exploratory well.

The BOP test went very well with all BOPE components functioning properly, and holding their respective pressure tests. During testing of the choke manifold, I found three threaded connections on the manifold along with what appeared to be Iow pressure threaded ball valves on the line running from the manifold to the shaker. I feel this setup does not comply with our guidelines of no threaded connections allowed on the choke system or its related components. Also, the placement of the ball valves was such that they should have been included in the choke manifold test, but the pressure rating was unknown and the decision had been made during the test to P&A the well. I felt a test of these valves was too dangerous because of unknown rating of valve and piping. Parker is to refabricate the system before the next well. Jimmy Pyron (ARCO rep) and Jim Kothe (Parker toolpusher) assured me if Rig #141 was picked up for another well, this would be accomplished before spudding. Summary: Although the BOP test went well, I found non-compliances in Parker 141's choke system. Test time 1.75 hrs, 1 failure. attachment STATE OF ALASKA OIL AND GAS CONSERVATION COMMISSION BOPE Test Report OPERATION: Drlg:.

Please consider this letter an addendum to our Application for Permit to Drill this well. While the best way of evaluating the potential for gas shallower than 2000' is via a high-resolution shallow seismic survey as specified in 20 AAC 25.061, this method does not yield meaningful results in intervals containing permafrost. Historically, offshore arctic well locations have been investigated with high-resolution shallow seismic surveys since there usually is no permafrost present. Onshore arctic wells have had to rely on other investigative methods. Since the Till location is expected to contain permafrost down to approximately 1200', other methods, discussed below, were used to search for evidences of shallow gas. Even though accumulations of shallow gas in or vertically near permafrost intervals cannot be detected directly, the presence of a significant accumulation may nevertheless create a "washout" below it in the deep seismic data obtained for evaluating the prospect geologically. The seismic data through the Till location was examined for such washouts, with no evidence of any found. Also, the drilling records of all of the surrounding offset wells were closely examined for evidence of any gas having been encountered shallower than 2000'. All wells within ten miles of the proposed Till location were examined, none of which evidenced any shallow gas. A list of the ten wells investigated is attached. Finally, the lack of evidence of shallow gas notwithstanding, a recent policy change within ARCO dictates a minimum mud weight of 10.0 ppg be used for drilling below permafrost to the surface casing point. This should help alleviate most unanticipated conditions, including minor amounts of gas, in the shallow part of the hole. If you have questions or require additional information, please give me a call at 263- 4511 in our AnchorAge office.

Johnston, Chairman Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Re: Application for Permit to Drill ARCO/BP/UTP Till gl Dear Commissioner Johnston, ARCO Alaska, Inc. hereby applies for a Permit to Drill an onshore exploratory well, the ARCO/BPFUTP Till gl, on State lands near the mouth of the Colville River. ARCO will act as operator for itself, BP Exploration (Alaska), Inc. and Union Texas Petroleum Alaska Corporation in evaluating acreage previously leased by ARCO Alaska, Inc., as successor in interest to Sinclair Oil & Gas Company and BP Exploration (Alaska), Inc., as successor in interest to BP Exploration Company (Alaska), Inc. Due to this well's proximity to a quarter-section line, a request for spacing exception has been sent to the Commission under separate cover. The proposed well location is approximately 4-1/4 miles south of the planned ARCO Kuukpik #3 and 5-1/2 miles southeast of the ARCO Fiord gl drilled in early 1992. The wellsite will be accessed via ice road originating at KRU 3H Pad. ARCO plans to use Rowan Drilling Company's Rig 33 to drill this well from an ice pad during the winter of 1992-93. Attached f'md the information required by 20 AAC 25.005(c) and 20 AAC 25.061. All waste drilling mud and cuttings generated during the drilling of Till # 1 will be hauled to the Kuparuk River Field for temporary storage and eventual processing by ball mill which will grind the cuttings prior to their being injected down an approved disposal well. The TD of this well will be at the base of the Nuiqsut Formation which directly underlies the Kupamk Formation. 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. However, all drilling mud, cores and produced fluids exiting the wellbore will be monitored for detectable levels of H2S.

Wayne McBride Area Drilling Engineer RECEIVED JAN 1 2 ~993 ^laska Oil & Gas Oons. r~ommissior, Anchorage SUPPORT DOCUMENTS FOR REQUEST FOR EXCEPTION TO 20 AAC2S.035(b)(1) (Bifurcation of Diverter Line) RECEIVED JAN 1 2 t993 AJaska Oil & Gas Cons. Commission Anchorage ARCO Alaska, Inc. hereby applies for an exception to the provisions of 20 AAC 25.035(b)(1), concerning bifurcation of the diverter line. 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, ARCO Alaska, Inc. has determined that a combination of one 16" line with no 90° tums 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 SW to NE. With perpendicular placement of the diverter line, there is minimum exposure of gas blowing back onto an ignition source (see attached weather data). 4) A gas dispersion model named "Focus" has been used to simulate flow out of a 16" single line at varying rates and wind speeds aimed towards the rig. Included with this request are outputs from this simulation. 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.

Test liquids are to be stored in tanks on the drilling location and pumped back into the reservoir after testing or taken to KRU for processing and shipping to the pipeline. Gas is to be flared. Testing will involve alternating flow periods and shut-in periods. Individual intervals may be tested separately by re-setting the coiled tubing and packer at the appropriate depths. Stimulation by acidizing and/or fracturing may be necessary. After completion of testing, use coiled tubing unit to abandon well per AOGCC regs. Re- spool the tubing on the coiled tubing unit and rig down. Move in and rig up workover rig. Using drill pipe as the work string, cut off and recover all casing at 15' BML. Rig down and release workover rig. Thoroughly clean and abandon the ice pad and ice road on the way out. RECEIVED JAN Alaska Oil & Gas Cor!s. Anchorage PRESSURE ANALYSIS TILL #1 (Per 20 AAC 25.005(c)(7), as required in 20 AAC 25.033(e)) RECEIVED PRESSURE ANALYSIS Till gl A geopressure analysis for the Till #1 well was performed using site specific seismic data and offset well information from the Amerada Hess #1 well in the vicinity of the proposed well location. The analysis was performed using ARCO's "GAS" (Geopressure Analysis System) software. Figure 1 shows the existing well data used to determine the regional compaction trend. The coefficients for this compaction trend are listed in the appendix. The offset well sonic data is then converted to mud weight equivalents using another equation called the 'pressure translation gradient'. This is compared to the existing mud weight data from the offset well. The coefficients of the pressure translation gradient are reworked until a close match is obtained between the mud weight actually used and the calculated mud weights from the sonic values. This step is called the well calibration phase and the results are shown in Figure 2. The actual coefficients used are detailed in the appendix. The seismic data is incorporated in the form of detailed velocity analyses around the proposed well site. The velocity analyses are converted to interval transit time (ITl') both in time (Figure 3) and in depth (Figure 4), and then converted to mud weight equivalents using the same coefficients derived from the offset well data. Figures 5 and 6 detail this mud weight equivalent data both in time and in depth. For this well the seismic line used was WKE92-05 and the well location is at SP 2320 CDP 4640. The proposed well is a planned straight hole so no deviation information was used. Seismic velocities were calculated across CDPs 4610 to 4670. The geopressure analysis shows some sign of an abnormal geopressure at approximately 3500'. This area is laterally consistent over very few seismic traces and may be a seismic phenomenon unrelated to geopressure. However, it does indicate that a mud weight of 9.0 ppg should be appropriate down to about 3000'. The mud weight should then be increased to 10.5 - 11.0 ppg by 3500'. The apparent pressure then decreases back to a 9.8 ppg equivalent mud weight until approximately 6100' at which point it increases gradually to 11.0 ppg at TD. The single trace plot is from the actual well location, however, it is at the very edge of the highest pressure zone (refer to Figure 6). This is the reason for the range given at 3500' above. Again, this zone is not very laterally consistent and may or may not be encountered in the well. Also attached is a summary plot which shows anticipated pore pressure, mud weight and fracture gradient curves. The fracture gradient is derived from leak-off tests conducted last year in the ARCO Fiord # 1 and ARCO Kalubik #1 wells as well as pressure integrity tests conducted in wells drilled by other operators in the Colville Delta area.

Mix an adequate surface volume (500 bbls) with Aquagel/X-Tend II to a funnel viscosity of 80 to 100 sec/qt with a yield point of 25 to 40 lbs/100 sq ft. Add caustic soda to adjust the pH to the 9 to 10 range for maximum bentonite yield. ~ Maintain the 80 to 100 sec/qt viscosity to the base of the permafrost (1400'- 1600' ) then reduce the viscosity as allowed based on actual hole cleaning requirements. A funnel viscosity of 50 to 60 sec/qt may be suitable by the 12 1/4" TD. It should be noted that actual viscosity requirements may vary based on the amount of surface gravel present. ~The initial mud weight of 9.0 ppg will be required for the base spud mud. At approximately 1100' TVD or base of the permafrost the mud weight should be at 9.6 ppg. The mud weight will be maintained at a minimum of 9.6 ppg through to TD of the surface interval. This is presently the current mud weight requirement for all the Kuparuk wells. PAC (polyanionic cellulose) treatments can be initiated toward the 12 1/4" TD for improved well bore stabilization by reducing the API fluid loss (8 to 10 cc's) 4.) Circulate and short trip the hole prior to running the 9 5/8" casing. It is suggested to make a lite treatment of Desco-CF to reduce the gel strengths prior to running the casing and cementing. 5.) Caution should be exercised on the short trips. All tight hole should be reamed. Pit volumes should be monitored and all solids control equipment should be turned off. The hole fill should be monitored on each trip to insure exact fluid displacement. 6.) Maximum utilization of solids control equipment is recommended throughout the surface hole drilling operations. Maintain the sand content at less than 1% by volume and solids as low as possible at all times. RECEIVE!) II. Production Hole: 8 1/2" Hole to Core Point Sua~ested Mud Properties: Density - 8.6 to 9.3 ppg Plastic Vis - 5 to 15 cP Yield Point - 6 to 12 lb/100 sq ft Viscosity - 36 to 42 sec/qt 10 Sec Gel - 2 to 4 cP 10 Min Gel - 4 to 8 cP API Filtrate - 8 to 10 cc pH - 9.0 to 9.5 Solids - < ? % 1.) Thoroughly clean the mixing pits and build 500 - 550 bbls of new fresh water mud as formulated below to drill ahead in the 8 1/2" hole below the 9 5/8" surface casing: Aquagel - 6 to 8 ppb X-Tend II - .04 ppb Therma-Thin - .25 ppb Caustic soda - .10 ppb The new mud will be mixed with the 9 5/8" casing volume of previous spud mud. The important properties for the initial 8 1/2" hole would include a pH in the 9.0 to 9.5 range, yield point in the 6 to 12 lbs/lO0 sq ft range and the API fluid loss in the 8 ~o 10 cc range. The initial funnel viscosity should be in the 36 to 42 sec/qt range or as dictated by actual well bore conditions. 2.) Treat the cement contamination with Bicarb and excessive rheology with Therma Thin/Desco CF. 3.) The viscosity of the mud in the 8 1/2" hole can be sustained with additions of Aquagel/Extend II. These treatments should be based on actual hole cleaning requirements. Maintain the viscosity in the range of 36 to 42 sec/qt, with yield point values of 8 to 12 lbs/lO0 sq ft range. 4.) Treatments with PAC/Drispac polymers should be used throughout this section of the hole to control the API fluid loss in the 8 to 10 cc range or as required based on actual well bore conditions. Low viscosity or high viscosity PAC/Drispac products (PAC-L/PAC-R ~ Drispac SL/Drispac R) are available for which ever application is appropriate. RECEIVED 5.) Control excessive theological conditions with additions of Therma-Thin on an as needed basis. Therma-Thin is an effective polymer deflocculant designed to provide effective theological stabilization. Additions of Desco-CF may be required to control excessive gel strengths and should be used moderately on an ns needed basis. 6.) It is recommended to make additions of prehydrated Aquagel to improve filter cake quality and aid in the control of the API fluid loss. The commercial bentonite content should be maint~ned in the 2 to 6 ppb range. Additional Aquagel additions may be considered as hole conditions dictate. 7.) Maintain the pH in the 9.0 to 9.5 range with additions of Caustic Soda. Note: Caustic Soda should be used in the Aquagel prehydration process to increase the pH in the range of 9.0 . 8.) Utilize all solids control equipment for maximum solids removal. Focus on achieving the finest screen arrangement possible on the shale shakers and use the secondary solids control equipment to maintain the solids as low as possible through this section of hole.

That is, If the KCL level (C1) is low in the system make calculated additions for the system using an increased % KCL in the 100 bbl batch mix. Maintain 1 ppb sodium bromide (NaBr) in all fluid mixes. a.) Build the batch mud as follows: lst- Prehydrate the Aquagel in fresh water. Do not build the gel slurry in a pit that contains KCL or add any caustic soda for prehydration. Wash out the pit if KCL has been mixed in it. 2nd-Make additions of PAC/Drispa¢ polymer. 3rd-Add the KCL. 4th-Add Baracarb and Baroid. Make additions of .2 ppg Aldicide G to all base drilling fluids.

GRI REFERS TO GAMMA RAY FROM DUAL INDUCTION TOOL STRING GRM REFERS TO GAMMA RAY FROM MAC TOOL STRING. GRZ IS THE DEPTH REFERENCE FOR THIS WELL. SINCE THE MAC TOOL WAS RUN IN COMBINATION WITH DIL ON RUN 1 THE DATA FROM SURFACE TO 1970 ON GRM IS IDENTICAL TO THAT OF GRI. ALL SPLICE DEPTHS WERE CHOSEN TO MAXIMIZE OPEN HOLE COVERAGE WHILE TRYING TO PROVIDE A SMOOTH SPLICE. OVERLAP BETWEEN RUNS WAS SUCH THAT COMPLETE OPEN HOLE COVERAGE WAS NOT POSSIBLE. THE FOLLOWING CURVES & DEPTHS REFER TO MEASUREMENTS DONE IN CASING: GRZ from 2000' - 2011'. GRM from 1970' - 2011'. MAC from 1996' - 2011'. ANY DATA ABOVE THE RUN 1 CASING POINT OF 144'. DRHO, PEF, CALl, MTEM, TENS, & TEND (from ZDL TOOL) WERE SHIFTED WITH RHOB. FUCT & NUCT WERE SHIFTED WITH NPHI. TEND & TENS (from DIL TOOL) WERE SHIFTED WITH LL8. SP WAS SHIFTED WITH ILD. CN WN FN COUN STAT C13 & C24 C~RVES ARE TAKEN FROM THE RUN 2 DIPLOG CAL- IPERS. THESE CURVES HAVE BEEN ACCELEROMETER CORRECT- ED. C13 WAS DEPTH MATCHED TO THE SHIFTED DENSITY CALIPER.
