Each of these wells was found to have a void in the conductor by surface casing annulus. The voids were filled with cement to the top of the conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serves as notification that the treatments took place. In the fall of 2002, CD 1-23 was reported to have a "wobbly" tree. The top of cement was measured at 15- feet below the top of the conductor. Plans were made to stabilize the wellhead by top-filling cement later in the winter when the ice road to Alpine had been installed. Since that is considerable effort and expense for pumping a small load of cement, a survey was made of each conductor to see if voids were present. A list of 34 wells was put together that would need additional cement. The top-fill operation was started on April 15th and was completed on April 16th, 2003. Dowell- Schlumberger batch-mixed Arctic Set I cement to 15.7 ppg in a blender. The cement was pumped via high-pressure hose into the conductor. The cement was brought to the top of conductor on each well. The blender/pump and hose worked down the line, filling the identified wells until the list was completed. The attached spreadsheet presents the well name, top of cement depth prior to filling, and the number of sacks used on each conductor. Please call MJ Loveland or Nina Woods at 907-659-7224, or me at 659~7043 if you have any questions.

Due to suspected wellhead damage three out of four tubing hanger seals have failed pressure test. It is proposed that the Doyon 19 drilling rig moves back over the well and recovers the tubing hanger to just above the wellhead to affect repairs. i Prior to this operation, the formation will be isolated by setting and pressure testing a through tubing inflatable bridge plug in the casing below the completion. This will provide the primary barrier against formation fluid influx. The packer tailpipe will also be plugged and the tubing pressure tested.

After double barrier isolation of the formation it is intended that the Doyon 19 drilling rig moves back over CD1-23 and recovers the tubing hanger to just above wellhead elevation to allow for replacement of seals on the hanger, or if the hanger is damaged, replacement of the hanger itself. The proposed operations are as follows: Pre-rip Preparation: Ri.q 1. Perform coiled tubing run to clean out suspected ice plug at +/-1350' in the tubing. 2. Recover the packer setting tailpipe ball and rod and perform a gauge survey with slickline. 3. Run a cement evaluation log with electric line (to show isolation above the top of the Alpine). 4. Set a through tubing inflatable bridge plug with electric line. Pressure test same to 1000 psi (Barrier #1). 5. Set a plug in the packer tailpipe with slickline. Pressure test same to 1500 psi (Barrier #2). 6. Set BPV in preparation for the rig. summary ORIG INAL . , 4. 5. 6. , 8. 9. 10. 11. 12. 13. 14. 15. 16. Center up the rig over the wellhead. Check the well status, remove BPV - with lubricator. Confirm annulus is static. Set the 2-way check in the hanger. N/D wellhead adapter. M/U landing joint to the tubing hanger. Release hanger lock down screws. Pick up the hanger approximately 4' (stretch tubing). Pull hanger plus pup above wellhead. Install false bowl on the wellhead. Set slips on the first joint of tubing below the hanger pup joint. Back out the landing joint. Replace the current hanger seals with elastomeric seals. M/U the landing joint. Remove the slips and false bowl. Run hanger back in, land and set lock screws. Pressure test the hanger seals to 5000 psi. Back out the landing joint. N/U the wellhead adapter.

TllN, R5E, UM Dear Mr. Chester: Enclosed is thc approvcd application for permit to drill the above referenced 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..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. and any CQLs must be submitted to the Commission on form 10-403 prior to the start of disposal operations. Please note that any disposal of fluids generated from this drilling operation which are pumped down the surface/production casing annulus of a well approved for annular disposal on Drill Site CD1 must comply with the requirements and limitations of 20 AAC 25.080. Approval of this permit to drill does not authorize disposal of drilling waste in a volume greater than 35.000 barrels through the annular space of a single well or to use that well for disposal purposes for a period longer than one vear. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25 035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given bv contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Note: Install diverter and function test. Move on Doyon 19. Drill 12 1/4 inch hole to the surface casing point as per the directional plan. Run and cement 9 5/8 surface casing. N/D diverter. Install casing head. Install and test BOPE to 3500 psi. Pressure test casing to 2500 psi. Drill out 20' of new hole. Perform leak off test. Stop at a 16 ppg EMW FIT if no leak off. Drill 8 1/2 hole to the intermediate casing point in the Alpine Reservoir. Note LWD will be run over the lower part of this section. Run and cement 7 inch casing as per program. Top of cement 500 feet above Alpine reservoir as per Rule 20 AC 25.030. Carry out a leak off test down the 9-5/8" x 7" casing annulus to confirm the fracture pressure referenced to the casing shoe. Freeze protect casing annulus and casing. BOPE test to 3500 psi. Run drilling assembly. Pressure test casing to 3500 psi. Drill out and perform formation integrity test to 12.5 ppg EMW. Drill 6 1/8" horizontal section to well TD. Contingency- set ECP scab liner or slotted liner if required (due to unconsolidated formation or wellbore having moved out of the Alpine reservoir sand). Displace well to brine and pull out of hole. Run 4 Y2, 12.6 #, L-80 tubing with production packer. Land hanger. Circulate in inhibited brine and diesel freeze protection. Drop ball and set packer. Test tubing and tubing-casing annulus separately to 3500 psi / 30 mins. Install BPV. Nipple down BOP. Install tubing head adapter assembly. Remove BPV. Install test plug. Pressure test adapter assembly to 5000 psi. Remove test plug. Set BPV and secure well. Move rig off. This well (and all other injectors) will be logged through tubing with a CBL/GR/CCL to determine cement isolation above the top of the Alpine. This will be done after the rig moves off location. Well Proximity Risks: Directional drilling / collision avoidance information as required by 20 ACC 25.050 (b) is provided in following attachments. CD1-24 will be the closest well to CD1-23 (9.1' at 348' MD). Accounting for survey tool inaccuracies, the ellipse separation between these wells will be 7.3' at 348' MD. Drillinq Area Risks: There are no high-risk events (e.g. over-pressures zones) anticipated. Lost circulation: Faulting within the Alpine reservoir section is considered to be the most likely cause of lost circulation. However, there are no faults progosed within 500 ft of the proposed target polygon. Good drilling practices will be followed to ensure that mechanically induced losses are kept to a minimum. Additional care and attention will be given to the higher potential of inducing a kick when drilling horizontally as opposed to vertically. Good drilling practices will be stressed to minimize the potential of taking swabbed kicks. Annular Pumping Operations: Incidental fluids developed from drilling operations on well CD1-23 will be injected into the annulus of a permitted well. The CD1-23 surface/intermediate casing annulus will be filled with diesel after setting intermediate casing. The only significant hydrocarbon zone is the Alpine reservoir and there will be 500' of cement fill above the top of the Alpine as per regulations. We request that CD1-23 be permitted for annular pumping of fluids occurring as a result of drilling operations, per regulation 20 AAC 25.080. As stated above, 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 at the base of the Schrader Bluff Formation (C-30). These 450-500' thick shales are part of the Colville Group and are known to provide vertical barriers to fluid flow in other areas. 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) * (2400') + 1,500 psi = 2,998 psi Pore Pressure = 1,086 psi Therefore Differential = 2998 - 1086 = 1912 psi. The internal casing pressure is conservative, since frictional losses while pumping have not been taken into consideration. The surface and intermediate casing strings exposed to the annular pumping operations have sufficient strength by using the 85% collapse and burst ratings listed in the following table: Wt Connection 85% of 85% of OD (ppf) Grade Range Type Collapse Collapse Burst Burst 9-5/8" 36 J-55 3 BTC 2,020 psi 1,717 psi 3,520 psi 2~992 psi 7" 26 L-80 3 BTC-Mod 5,410 psi 4~599 psi 7,240 psi 6,154 psi CD1-23 DRILLING FLUID PROGRAM SPUD to Intermediate hole to 7" Production Hole 9-5/8"surface casing casing point- 8 Y2" Section - 6 1/8" point- 12 ¼" (including coring of pilot hole) Density 8.8 - 9.6 ppg 9.4 - 10.0 ppg 9.2 ppg PV 10 - 25 12 -18 YP 20 - 60 15 - 25 35 - 45 Funnel Viscosity 100 - 200 Initial Gels 4 - 8 18 - 22 10 minute gels <18 23 - 27 APl Filtrate NC - 10 cc/30 min 4- 12 cc/30 min (drilling) HPHT Fluid Loss at 160 <10 cc/30 min PH 8.5 - 9.0 9.0 - 10.0 9.0 - 9.5 KCL 6 % Surface Hole: A standard high viscosity fresh water / gel spud mud is recommended for the surface interval. Keep flowline viscosity at _+ 200 sec/qt while drilling and running casing. Reduce viscosity prior to cementing. Maintain mud weight < 9.6 ppg by use of solids control system and dilution where necessary. Intermediate Hole Section: Fresh water gel / polymer mud system. Ensure good hole cleaning by pumping regular sweeps and maximizing fluid annular velocity. There is potential for lost circulation, particularly after the Alpine is penetrated. Maintain mud weight at or below 10 ppg and be prepared to add loss circulation material. Good filter cake quality, hole cleaning and maintenance of Iow drill solids (by diluting as required) will all be important in maintaining wellbore stability. Treat mud with fluid loss additives prior to coring. Production Hole Section: The horizontal production interval will be drilled with a M-I FIo-Pro drill-in fluid. The base fluid will consist of 6% KCI, with _+ 30PPB calcium carbonate bridging material to minimize formation damage. FIo-Vis Polymer and FIo-Trol starch will be used for viscosity and fluid loss control respectively.
