Well names currently include a forward slash "/" followed by an obsolete bottom hole location designator. HAK would like to retain the well number as well as the "A, B, C...." sidetrack designations but remove the "/suffix". For example, "DUCK IS UNIT SDI 1-09A/L21" would become "DUCK IS UNIT SDI 1-09A". The attached spreadsheet includes original and new names for all Duck Island wells. While performing the review of Duck Island well names, HAK found a single well, "DUCK IS UNIT SDI 4-20/M35" (PTD# 1861730), that should also be modified to include an "A" label to reflect the fact that the well is a sidetrack from the original "DUCK IS UNIT SDI 4-20/T34" (PTD# 1861500). The original wellbore, abandoned 10/13/1986, was sidetracked to a new bottom hole location completed on 9/9/1987. This well appears to be one of the first sidetracks performed at Endicott. While the bottom hole code was changed, no letter was added to reflect the sidetrack. "DUCK IS UNIT SDI 4-20A" is also included on the attached spreadsheet.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

Doyon 15 has been stacked all summer and this was the second BOPE test since their start up. I found the rig in good condition and the drilling crew well trained. As the attached AOGCC BOPE Test Report indicates the test went smoothly and there were no failures. The 9 5/8" casing was run without problems and 75 bbl's of good cement was received at surface. Circulation was lost after pumping 49 bbl's of the 61 bbl 15.8 PPG tail cement however the cement to surface did not drop indicating a good cement job. A copy of the BPX morning drilling report covering the events of the cement job is attached for reference. Shared Services Drilling has instituted a new leak off procedure a copy of this new procedure is attached for reference.

Corrective measures will be performed if the open hole pressure integrity fails to meet pre-determined standards. The Recommended Practices manual further def'mes this specification in two places: RP- Surf Hole Page 3 and RP-Intermediate Hole Page 4. In RP-Surf Hole section, steps 14 & 15 on page 3 contain the general procedure for conducting a LOT below surface casing. On RP-Intermediate Hole Page 4, the entire page is given to a discussion of performing an FIT or a LOT below intermediate casing. PROCEDURE The LOT procedure is further detailed in the following discussion. NOTE: .This discussion is applicable for development wells only! For explanation of these steps or a discussion about interpretation of the results, refer to the BP Well Control Manual in Sections 4.6 d.8. A pressure recorder chart is required for all pressure tests and must be clearly labeled before being sent to the SSD office for inclusion in the well file. Suitable gauges for the anticipated pressure range which have been recently calibrated should be used, unless previous test results have validated the accuracy of a rig's digital gauges. Also, if a rig pump cannot be run at a steady low rate (0.25 0.5 bpm), use of a cementing pump should be considered. 1. Assess the upper limit of the test. The absolute upper limit for all types of tests will be the overburden gradient at 1 psi/ft. If the test is being conducted on an intermediate string, consider the casing pressure test or blowout preventer pressure limitations. 2. Determine the estimated fracture pressure. If this is unknown, consult with the Drilling Superintendent. A mud logging company can provide data for earl/er wells and the previous wells' records should provide some expectation for the estimated pressure. 3. Test the casing prior to drilling out the float collar. SSD Reco~nmended Practices June 1996 The anticipated volume to pressure up the casing can be estimated from the formula in Section 4.7 of the BP Well Control Manual. Run the mud pump at a constant 0.25--0.5 bpm. One-stroke pressure readings are recommended, but in all cases record pressures in at least five-stroke increments. If the pressures are increasing rapidly enough to make this reading too large, take pressure readings at 30-second intervals. Plot the results for reference during the following LOT. when the required test pressure is reached, suspend pumping and hold the test pressure for thirty minutes. Check that the test is being accurately recorded on a chart. 4. Drill cement, float collar, float shoe and 20'-50' of new hole. 5. Circulate bottoms up to condition the mud to a constant mud weight. 6. Pull into the casing shoe. . Close a blowout preventer. . 8. Run the mud pump at a constant 0.25 or 0.5 bpm. 10. Match the pump rate to the one used during the previous casing pressure test. Monitor the pressure build-up and accurately record the volume of mud pumped. Plot the pressure versus volume of mud pumped. Stop the pump when any deviation from linearity is noticed. Record the f'mal pump pressure and calculate the equivalent mud weight: Note .and record the bleed-off pressure in thirty-second intervals for five minutes. Bleed back mud from the well and compare with the volume pumped. Note the LOT results on the IADC ~heet and note on next morning's report. Send the leak-off test plot and pressure recorder charts to the office to be stored with the rest of the reports in the well ffie. If taking the pressure to full leak-off is not required (as is common in many developmental wells) or is deemed to be detrimental (such as doing a LOT in a brittle formation that would be weakened by going to full leak-off), an Equivalent Mud Weight Test (commonly known as a "jug test") can be conducted, with proper approvals, to just below anticipated leak-off pressure. 1. Determine the required surface pressure. In the case of a surface casing shoe, a 12.5 ppg EMW should be sufficient unless the well plan notes differently. 2. Test the casing prior to drilling out the float collar. Run the mud pump at a constant 0.25 0.5 bpm and record results as discussed in the above procedure for the LOT. SSD Recommended Practices June 1996 3. Drill remaining cement, float collar, float shoe and 10' of new hole. 4. Circulate bottoms up to condition the mud to a constant mud weight. 5. Pull into the casing shoe. 6. Close a blowout preventer. 7. Run the mud pump'at a constant 0.25 - 0.5 bpm.- Match the pump rate to the one used during the previous casing pressure test. 8. Stop the pump when the required test pressure is reached. Close appropriate valves if surface leaks are suspected. 9. Hold and record the pressure for five minutes. Check to ensure that the chart recorder is accurately recording the test. 10. Bleed back mud from the well and compare with the volume pumped. Note the jug test results on the IADC sheet and note on next moming's report. Send the test plot and pressure recorder charts to the office to be stored with the rest of the reports in the well file. If there arise any questions from these procedures, consult with your appropriate Drilling Superintendent. SSD Recommended Practices June 1996 Hazards: · Pressure: Abnormal~ hiah pre_ssures of up to 5000 psi may be encountered in the 3C due to gas injection approximately 1600' downdip of the target loc.~tion at well 3-47/Q-35, Pressure in the 3B is un(~ertain, and range from 2900 to 4500 psi.

Maintain this viscosity until the large gravel has been drilled. When the amount of gravel lessens at the flowline, the viscosity can be slowly relaxed to a final viscosity of 100. High pump rates are important in this size hole to assist in hole cleaning. Past wells have had success in the 600-760 gpm range. Run all solids control equipment to keep the abrasive solids to a minimum. Additions of Condet(drilling detergent) may be needed for bit bailing and/or shaker screen blinding in the lower section of the interval. Prior to tripping out for the casing, the viscosity should be no lower than 100. Thinning the mud with dilution and Desco while circulating the casing should assist the displacement procedure and lessen the cement channeling. Hazards/Concerns: No special hazards anticipated. Intermediate Mud Properties: Subject to change based on actual drilling results.

This diluted fluid will be blended with the fluid in the well to form the base fluid for the LSND system. After drilling out the casing, treat out the cement contamination and establish filtration and rheological properties using PAC products. Maintain the pH in the 9.0 range using caustic soda. Supplement the hole cleaning with regular pumping of high viscosity sweeps consisting of Biozan. 4-34 / O-38 Drilling Program 9/19/96 The density should start out in the8.8- 9 ppg range. At 9200' begin weighting up mud and ensure the weight is 9.6 by 9700 MD. Use all solids control equipment and dilution to hold the weight in the desired range. Begin additions of 2#/bbl each of Baranex and Barotrol at approximately 8000 MD. This will lower the filtration rate from the 7-8 cc range to the 4-6 cc range and help stabilize any shales encountered. Maintain this range for the remainder of this interval. If a PDC bit is to be run, pretreat the system with l#/bbl of Condet prior to tripping for this bit to minimize the potential for bit bailing. Maintenance with the Condet and SAPP are recommended. The tangent section of this hole can be considered straight so the need for lubricants should be minimal. If torque or drag become a problem here, l-2ppb of Torq Trim II and/or EP Mudlube are recommended, depending on the source of the problem. Hazards/Concerns: Treat with shale stabilizers. Use soap and SAPP for bit bailing. Potential for need of lubricants. Use high vis sweeps to assist in hole cleaning. Higher mud weights may be required for hole stabilization and/or gas. Monitor pit volumes and flow closely. Maintain an adequate stock of LCM on location at all times. Horizontal Mud Properties: Subject to Drill in fluid change based on actual hole drilling results.

Utilize N-vis to maintain the Bingham yield point and Iow shear rate yield point in the specified ranges. Daily calculations of Tau O should be performed by the mud engineer to assure agreement with the Iow shear rate YP. Brookfield data will be reported for comparison purposes only. Maintain the APl filtration rate < 6.0 cc with additions of CAT 300 and N-Dril Lo. These maintenance additions should be made at a 4 to 1 ratio,CAT 300 to N-Dril LO. High viscosity sweeps should be mixed using N-Dril Hi, a high molecular weight polymer~ If sliding problems or drag are experienced, treat the system with EP Mudlube at a concentration of 1%.Do not use Lubetex in the Sheardriln system due to incompatibility. Use Baracarb for dry jobs,not KCL as there's a 12,000 ppm hardline maximum on chlorides. Chlorides are needed in this range to facilitate the logging program, 8,000 to 10,000 ppm should be considered the ideal chloride content. A disPlacement procedure is attached which can be modified at the rig to accommodate rig operations and time savings. Hazards/Concerns: Potential for lost circulation dictates adequate supplies of LCM on location. Lubricants for sliding, drag, and torque. Maintain chlorides in 8,000 to 10,000 range. Do not use KCL in dry jobs. Monitor pit volumes and flow closely. Maintain Baracarb inventories sufficient to weight up at least .7ppg. 4-34 / 0-38 Drilling Program 9/19/96 Open hole displacement procedure Prior to beginning the 15 degree build at 9886 MD, reduce the yield point of the LSND system to the 8 to 10 range, and trip to the surface casing shoe to prepare the rig pit system to receive the 2% KCL drill-in fluid from the Baroid mudplant and to build the Iow viscosity and high viscosity spacers. Dump and clean the rig pits and flush all pump and solids control equipment lines with fresh water. Take the KCL fluid into the pits and displace after tripping back to bottom according to the following procedure: 1)Pump a 50 barrel Iow viscosity sweep consisting of a mud from the LSND system which has had the Bingham yield point reduced to 6 lb/100 sq ft through additions of chrome free Desco. 2)Pump a 50 barrel high viscosity spacer consisting of N-Vis mixed to a Bingham yield point of 35 to 45, (approximately 2.5 ppb), and weighted to 9.6 ppg with barite. Proper manipulation of pH to ensure proper polymer dispersion and hydration along with slow mixing of the polymer will prevent the formation of polymer fish eyes. 3) Once the high viscosity spacer is away, begin displacing with the 2% KCL fluid. Pump at the highest practical rate possible and rotate and reciprocate the drill string to provide turbulence in the annulus and to disturb any solids which might be laying on the Iow side of the well bore. 4)Monitor flow line returns for break through of the spacers and the KOL fluid. Discard the Iow viscosity and high viscosity spacers as they will be contaminated with unwanted drill solids and cuttings which might compromise the integrity of the KCL drill-in system. Any of the suggestions in the beginning paragraph can be changed to better utilize rig time. Casing and Cementing' In th'e past the standard casing program has been the slimhole design which utilized 10 3/4" casing for the surface hole and 7 5/8" casing for the Iongstring. Now the next step in the evolution of casing size leads us to a 9 5/8" surface string and a 7" production long string. Going to the smaller casing should benefit the drilling program in a variety of ways and yet maintain the same parameters needed for production. A cost savings should be realized through less casing costs, less bit costs, higher penetration rates, less rig time, reduced cement costs and less disposal costs due to the reduced volume of cuttings. Cementing the surface-casing will involve the use of a stab-in assembly which will give us more probability of getting cement to surface. It is imperative that good returns are evident when the surface hole is at TD. If for any reason there are any losses at surface. TD, those losses must be dealt with and full returns must be established prior to pulling out of the hole with the drill pipe. Under no circumstances should the drill pipe be pulled from the hole if partial losses still exist. See attached cement volume summary. Centralizer Placement: The 9 5/8" casing will require 10 centralizers to be placed on the first 10 joints in the hole. The 7" casing will require 2 straight blade centralizers per joint from 12529' to 9396'. The total number of centralizers for the 7" will be 155. 4-34 / O-38 Drilling Program 9/19/96 Well Control: Well control equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures. Diverter, BOPE and drilling fluid system schematics on file with AOGCC. Directional: I KOP: I Surface nudge, KOP at 3600' MD I IMaximum Hole Angle: I 16'° in surface and 88.9° in Horizontal Close Approach Well:1 4-38 / K-34 is 77 feet at 4517 TVD The above listed wells will be secured during the close approach. Deep well intersections NONE. The directional on this well involves a horizontal section without drilling a pilot hole. The control will be very critical as the well is drilled. The surface hole has one close approach issue on well 4-38/K-34 which will be shut in. Several other wells do not exceed the close approach criteria but are close and will require a constant vigilance by the directional driller to prevent drilling over any hard lines. The surface hole will have a slight nudge to 3° at 300 feet to avoid a close well issue. The hole will then be drilled down to the next kickoff point at 3500' where it is to be built to 16.5° at 2.5°/100'. The azimuth must be 82° during this build. All of the critical hard lines occur in this surface hole and must be watched closely. The surface hole is to be drilled to 4647' and the 9 5/8" casing run and cemented. The 8 1/2" hole will be drilled from the 9 5/8" shoe at 16.8° of angle and at 9930' MD the angle is to be built at 15°/100, up to 65° with an azimuth of 80°. This angle will be held to a depth of 10252' and then built up further at 8°/100' up to 89° with an azimuth of 80°. Note: A pilot hole has not been drilled and the control as to where the tops of formations are will be determined as the production hole is drilled. Therefore, the top of the Itkilyariak is predicted to come in at 9862' TVD (10252' MD) and the hole angle should be _+65°. If at this point it is determined that the Itkilyariak is Iow then the angle should be held at 65° until the harder formation (Itkilyariak) is encountered and bulling angle can resume. After building to 75° the bottom of the Itkilyariak should be seen with a definite increase in penetration rate. If at 75° the bottom of the Itkilyariak has not been encountered then hold the 75° until a noticable penetration rate increase is observed and then continue building to 89° in the Kekiktuk sand at _+9986' TVD. The 89° angle is to be held to a measured depth of _+12743 MD where the angle will be dropped to 65° at 8°/100' and maintain an 80° azimuth. The well will then be drill to 13820'MD TD and 7" casing is to be run. Disposal: Annular Injection: All cuttings will be hauled off location. There will not be any annular injection for this well. 4-34 / O-38 Drilling Program 9/19/96 . . . . . . . . ,, 10. 11. 12. 13. 14. 15. 16. 17. 4-34 / 0-38 Proposed Summary of Operations Drill and set 20" conductor.

Review H2S risks, spill prevention, and well control. While making up the guns make sure that only essential personnel are present on the rig floor. Rig up tank away from rig and plumbed to accept returns from the well. (Dike and berm the tank) While picking up and running the perforating guns and associated tools (firing heads etc.) there should be only essential personnel on the rig floor (driller, perforating crew and packer hand). All other personnel will stay off of rig floor until the perforating equipment is below the rotary table. Perforating guns will be run with hand slips (not air slips). It is imperative that all slip dies be inspected prior to running the guns. (Dies that are dull will tend to let the guns slip and catch causing the charges within to shift and possibly rotate out of the scalloped area of the gun) 4) MU Perforating/underbalanced assembly in the following order: Absolute pressure firing head Perforating guns & blanks, as per production specs. Differential Pressure Firing Head 2-7/8" PAC 6.4# L-80 tubing (from Doyon 14 if the rig doesn't have any) Below Packer Safety Joint Bypass Port Champ III Packer ( To be set in the 7-5/8" casing @ < 60° hole inclination) Hydraulic underbalance valve Jars PR FAS-FIL Valve 3- 1/2" DP to surface (as required to space out above the liner top) Notes: · Schlumberger will provide BHA detail diagram. · Caliper all tool lengths and OD's. · Have the 2-7/8" PAC tubing inspected prior to every job and do not run pup joints in the 2 7/8" segment. · Insure that the packer setting depth will not be in an area that exceeds 60° of inclination or an area of high dog leg severity. · Space out packer by allowing LC to be tagged w/firing head. Pickup and place bottom shot at the requested depth. · In order to set guns on depth with drillpipe measurement, a strap of the cleanout string is essential. · Below Packer safety joint should be set to shear @ 70K#. · Pin PR FAS-FIL valve to shear at hydrostatic pressure required to achieve desired underbalance. Set valve to give a desired underbalance. Shear pressure = Reservoir pressure-underbalance. 5) RIH w/assembly on DP. Note TVD and MD at which PR FAS-FIL valve is set to shear. Stop at this depth, close annular, and pressure annulus to 400 psi. No flow up DP indicates valve has closed. If valve has not closed, release pressure and repeat. Fill drill pipe with fluid to this point. Continue in hole with dry pipe. In the event the PR-FAS-FIL is not actuating properly, POOH and investigate (do not continue RIH). 6) Tag LC w/firing head and position guns on DPM. 4-34 / O-38 Drilling Program 9/19/96 7) 8) 9) 10) 11) 12) 13) 14) Set the Champ III packer with 1/4 turn (at tool) to the right and 20K# down weight. R/U HOWCO flow head. Shoot fluid level inside DP to verify fluid level, shut annular on drill pipe. Ensure that the hard line to the outside tank is ready by having a visual inspection done from the floor manifold all the way through to the tank. Aisc dedicate one person to monitor the tank and the outside lines during the flow period and while reversing out any produced fluids. Pressure test all lines to 3000 psi. Fire the guns by pressuring up on the annulus to +_2500 psi. Monitor guns firing with the fluid level equipment. Once guns have fired bleed annulus pressure to 500 psi. If the differential firing head fails, the absolute firing head will be pinned to fire at +2000 psi applied at surface on the tubing. Prior to firing the absolute firing head, it will have to be determined whether underbalance is necessary, if so, then the string will have to be pressured up with nitrogen to 2000 psi and then bled off during the delay period of 15 minutes before the guns fire. If underbalance isn't a factor then fill tubing, open the packer by-pass, and circulate around to ensure the underbalance valve is open. Once that is established, close the by-pass valve and pressure up tubing to 2000 psi and bleed off to zero during the 15 minute delay period. Note: All guns can be run with the Absolute Firing Head with the exception of the 2 1/2" guns. Flow well and monitor with the fluid level indicator every 5 minutes and by the amount of blow in the bucket. Take any returns to the outside tank. Bleed off the pressure on the annulus. PU 20K to open by pass and reverse out tubing two tubing volumes, flowing produced fluids to the outside tank. Unseat packer, monitor well for flow or losses and allow the packer elements to relax prior to pulling out of the hole. POOH and monitor fill-ups closely, when the first gun is to surface have a short safety meeting reiterating to the crew that the guns could possibly have trapped gas and that extreme caution is needed when breaking connections (especially the blanks between spent guns). LD perforating guns and insure that the hole is kept on continuous fill. Establish that all guns have fired and if they haven't then again only essential personnel will be on the rig floor to dismantle the guns. RD equipment of perforating personnel and lay guns out for removal. Inspect and report all shots fired or misfired. Please perforate the following interval with Schlumberger charges (4.5", 5 SPF, EJ 51B with 60° phasing). Perforated well 500-800 psi underbalanced Peforation intervals will be determined from logs.

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. Blowout 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.
