Well 14-44 was drilled and completed late in 1995. The well was a significant step out into the southern periphery at DS 14. The well was completed with a long (2200') slotted liner and placed on production. The well initially produced 7700 BOPD at a 22% WC with a GOR of approximately 1000. After a period of one year production had fallen to 400 BOPD and water cuts had reached 90%. A review of the drilling records and coherency data for the area, reveal that lost circulation (11,000 bbl) associated with the fault network contacted by this well bore help explain the producing results. Initially, the faults loaded the well bore with Iow water cut oil and enabled production at rates not usually seen from Zone 4 completions. Before long however, the faults became conduits to water and water cuts rose to 90 percent. Completion of the well bore with a slotted liner left very few options for remedial work. In September of 1996, a MARCIT gel water shutoff job was attempted. Over 6,000bbls of gel were pumped into the well bore in an attempt to reduce/eliminate water production sourced from the nearby fault(s). The job was marginally successful and the well continued to produce very high water cut oil. Gross fluid rate was reduced by approximately 1500 BFPD without any corresponding loss to oil production. In February of 2002, a tubing caliper survey was run in the well bore to access the condition of the tubing for a possible through tubing sidetrack. The survey found increasingly corroded tubing down to approximately 5300'. A hole was noted on the survey in an area of partially collapsed tubing. The minimum ID on the collapse was small enough that it would have forced any future sidetrack to be drilled with tiny tools. The decision was made at this point to pursue a sidetrack location using a rotary rig. The well has produced 1.08 MMBO to date. The last well test, on the 17th of July, was 136 BOPD at 95% water cut with a GOR 244 scf/stb. The 14-44A sidetrack is currently scheduled for Nabors rig 2ES, beginning around October 01, 2002, after the completion of the A-22 RWO. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. .Scope Pre-Riq Work: * Notify the field AOGCC representative with intent to plug and abandon * . Rig up slick line, drift and tag 4 ½" tubing X 4 ½" slotted liner to top of fish at -12,511' MD. NOTE: there is a minimum I.D. at 5,151' MD of -3.5", according to the WSR dated 07/01/00. Confirm the pass through I.D. of the restriction in preparation for the upcoming tubing cut. Rig up coiled tubing and perform a cement P&A of the production interval/slotted liner within Zone 4. NOTE: there exists a fish at 12,511' MD, within the slotted liner. The fish, 3 production packer slip segments, is currently -13 feet beyond the 7 5/8" shoe. With the fish preventing clear passage to TD of the horizontal interval, it will be necessary to bullhead the cement around the obstruction, through the slots, until sufficient volume has been pumped to fill the production hole to approximately 200' MD beyond the horizontal landing point. This will place cement to a depth of approximately 13,100' MD. 14-44 Application for Sundry An additional volume of cement will be pumped to fill the 4 ½" tubi, pg to a depth of 12,000' MD. Estimated cement volume required to complete this P&A is 40 bbls. 3. Rig up slick line. Drift and tag top of cement to confirm the 4 W' tubing is clear to the planned tubing cut depth of 11,950' MD. Document TOC. 4. Fluid-pack the 4 ½" tubing and 7 5/8" x 4 W' annulus to surface. Note: a tubing caliper was run 2/22/02. It indicates some areas of significant corrosion (85% penetration) and one hole at 5,307' MD. Pressure-test the integrity of the cement plug and 7 5/8" casing to 3000 psi for 30 minutes. 5. Rig up E-line and chemical / jet cut the 4 W' tubing at _+ 11,950' in the middle of a joint. NOTE: the reduced I.D. at 5,151' MD will require the 3 3/8" cutting head, for clear passage to the proposed cutting depth. 6. Displace the well to clean seawater by circulating down the tubing through the tubing cut. Continue to circulate until clean seawater returns to surface. Freeze protect top 2,200' MD with diesel. 7. Test the 7 5/8" pack-off and tubing hanger seals. 8. Bleed casing and annulus pressures to zero. 9. Remove the well house. If necessary, level the pad. Please provide total well preparation cost on the handover form. Ri.q Operations: 1. MI/RU Nabors 2ES 2. Circulate out freeze protection and displace well to seawater. Set TWC. 3. Nipple down tree.

Well 14-44 was drilled and completed late in 1995. The well was a significant step out into the southern periphery at DS 14. The well was completed with a long (2200') slotted liner and placed on production. The well initially produced 7700 BOPD at a 22% WC with a GOR of approximately 1000. After a period of one year production had fallen to 400 BOPD and water cuts had reached 90%. A review of the drilling records and coherency data for the area, reveal that lost circulation (11,000 bbl) associated with the fault network contacted by this well bore help explain the producing results. Initially, the faults loaded the well bore with Iow water cut oil and enabled production at rates not usually seen from Zone 4 completions. Before long however, the faults became conduits to water and water cuts rose to 90 percent. Completion of the well bore with a slotted liner left very few options for remedial work. In September of 1996, a MARCIT gel water shutoff job was attempted. Over 6,000bbls of gel were pumped into the well bore in an attempt to reduce/eliminate water production sourced from the nearby fault(s). The job was marginally successful and the well continued to produce very high water cut oil. Gross fluid rate was reduced by approximately 1500 BFPD without any corresponding loss to oil production. In February of 2002, a tubing caliper survey was run in the well bore to access the condition of the tubing for a possib!e through tubing sidetrack. The survey found increasingly corroded tubing down ~ to approximately 5300. A hole was noted on the survey in an area of partially collapsed tubing. The minimum ID on the collapse was small enough that it would have forced any future sidetrack to be drilled with tiny tools. The decision was made at this point to pursue a sidetrack location using a rotary rig. The well has produced 1.08 MMBO to date. The last well test, on the 17th of July, was 136 BOPD at 95% water cut with a GOR 244 scf/stb. The 14-44A sidetrack is currently scheduled for Nabors rig 2ES, beginning around September 15, 2002, after the completion of the H-02A sidetrack. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Scope Pre-Riq Work: * Notify the field AOGCC representative with intent to plug and abandon *//, 1. Rig up slick line, drift and tag 4 ~" tubing X 4 ~" slotted liner to top of fish at -12,511' MD. NOTE: there is a minimum I.D. at 5,151' MD of -3.5", according to the WSR dated 07/01/00. Confirm the pass through I.D. of the restriction in preparation for the upcoming tubing cut. 2. Rig up coiled tubing and perform a cement P&A of the production interval/slotted liner within Zone 4. NOTE: there exists a fish at 12,511' MD, within the slotted liner. The fish, 3 production packer slip segments, is currently -13 feet beyond the 7 5/8" shoe. With the fish preventing clear passage to TD of the horizontal interval, it will be necessary to bullhead the cement around the obstruction, through the slots, until sufficient volume has been~p~ped~L,_ ~j~E£~t° ('~i;"~-'fill thet.~ /,'pr°ducti°n" .... hole to , 14-44 APplicatio~'i'i ! ':i four!: Sund~, approximately 200' MD beyond the horizontal landing point. This will place cement to a depth of approximately 13,100' MD. An additional volume of cement will be pumped to fill the 4 ½" tubing to a depth of 12,000' MD. Estimated cement volume required to complete this P&A is 40 bbls. '''~ 3. Rig up slick line. Drift and tag top of cement to confirm the 4 ¼" tubing is clear to the planned tubing cut depth of 10,750' MD. Document TOC. 4. Fluid-pack the 4 W' tubing and 7 5/8" x 4 %" annulus to surface. Note: a tubing caliper was run 2/22/02. It indicates some areas of significant corrosion (85% penetration) and one hole at 5,307' MD. Pressure-test the integrity of the cement plug and 7 5/8" casing to 3000 psi for 30 minutes. 5. Rig up E-line and chemical / jet cut the 4 ½" tubing at _+ 10,750' in the middle of a joint. NOTE: the reduced I.D. at 5,151' MD will require the 3 318" cutting head, for clear passage to the proposed cutting depth. 6. Displace the well to clean seawater by circulating down the tubing through the tubing cut. Continue to circulate until clean seawater returns to surface. Freeze protect top 2,200' MD with diesel. 7. Test the 7 5/8" pack-off and tubing hanger seals. 8. Bleed casing and annulus pressures to zero. 9. Remove the well house. If necessary, level the pad.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular Disposal Records from July 25, 1995 through present time. We compared your list with our records and are able to provide you with the following data: · Individual Annular DiSposal Logs from the SSD database which coincide with the approved wells on your attached AOGCC Annular Log. The SSD records are provided to you in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · Endicott wells 1-03/P-16, 1-65/N-25, 1-59/0-24 · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 &#2, K-05, K-02, H-07, K-25, K-37, E-17, F-21, K-30, K-34, K-21i, F-66, K-06, K-54, K-33, F-49i, K-18 · PBU Wells E-38, 18-34, 15-42, S-29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated from these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarify this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a SUndry " Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wells.

As discussed this morning we propose setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid 'wastes. There are no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter.

Fluid Handling: All drilling and completion fluids can be annular injected. Request to have well DS 14-44 for annular pumping. Request to AOGCC for Annular Pumping Approval for DS 14-44: 1. Approval is requested for Annular Pumping into the DS 14-44 10-3/4" x 7-5/8" casing annulus. 2. As referenced in Area Injection Order #4, there are no drinking water aquifers in the Prudhoe Bay Field Eastern Operating Area (including the Lisburne Oil Pool), as the average level of Total Dissolved Solids (TDS) at the ambient water within the proposed project area is above 10,000 ppm. There are no domestic or industrial use water wells located within one mile of the project area. 3. The 10-3/4" casing shoe will be set at 3305' MD (3230' TVD) which is below the Permafrost and in shale formations in the Sagavanirtok above the Ugnu Formation. 4. The burst rating (80%) for the 10-3/4" 45.5# NT-80 casing is 4170 psig while the collapse rating (80%) of the 7-5/8" 29.7# L-80 casing is 3830 psig. The break down pressure of the ~Jgnu formation is 13.5 ppg equivalent mud weight. The Maximum Allowable Surface Pressure while annular pumping is calculated according to the following equation and is 2465 psi for a 10.0 ppg fluid in this well (Assumes worst case in which 7-5/8" casing is filled with gas). MASP = 3830 psig - ((fluid density ppg - 1.9) X 0.052 X 10-3/4" Casing Shoe TVD) 5. A determination has been made that the pumping operation will not endanger the integrity of the well being drilled by the submission of data to AOGCC on 7/24/95 which demonstrates the confining layers, porosity, and permeability of the injection zone. The cement design for this well ensures that annular pumping into hydrocarbon zones will not occur. ¸6.
