To: Blair Wondzell - AOGCC Date: June 3, 1999 William Isaacson Re-Enter Suspended Well DS S-11Al for Sidetrack Operations Form 10-403 Attachment APl #50-029-20728-01 From: Subject: Reference: This memo is written as an attachment to form 10-403 for the re-entry of the suspended well DS S-11Ai (APl #50-029-20728-01). The 6" open hole interval was plugged back and abandoned prior to suspending operations on the well during the November 1998 sidetrack operations. Nabors 9ES is expected to move on S-11Ai in late June and re-enter the well to sidetrack to a different bottom hole location. November 1998 Sidetrack Operations Well S-11Ai was planned as a WAG injection extended horizontal sidetrack targeting Zone 4. The original completion was retrieved and a whipstock window milled, exiting the 7" casing at 9138' / 8607' TVD (at the top of Sag River). Perforations below the kickoff point were P&A'd during pre-rig operations. The 6" production wellbore was drilled from the whipstock window at 9138' to a final TD at 11,050'. The wellbore crossed an unmapped rubble zone where lost circulation was reported as high as 900 bph. The drill string became stuck at 9850' while attempting to control the lost circulation. Subsequent fishing operations failed to retrieve the drill string, which was backed off at 9297'. Plans to plug back the well included setting a balanced cement plug from the top of fish at 9297', extending up into the 7" casing -300' above the whipstock window. An initial attempt to plug back the well failed when the cement apparently fell downhole after being spotted. A second plug of larger volume was then successfully spotted from on top of the fish at 9297'. The cement plug was tagged at 8528' and pressure tested to 3000 psi. This places the TOC in the 9-5/8" casing, approximately 100' above the 7" liner top and 610' above the whipstock window. See attached schematic for details. Planned Sidetrack Operations 1.

To' From: Subject: Blair Wondzell - AOGCC C. Michael Jackson S-11Ai Proposed Suspension Form 10-403 Attachment Date: December 10, 1998 DESCRIPTION OF SCOPE CHANGE Well S-11Ai(API #50-029-20728-01) is planned as a WAG injection extended horizontal sidetrack targeting Zone 4. The original completion was retrieved and a whipstock window was milled exiting the 7" casing at 9138'(8607' TVD) at the top of Sag River. Perforations below the kickoff point have been P&A'd during pre-rig operations. The 6" production wellbore was drilled from a whipstock window at 9138' crossing an unmapped rubble zone where loss circulation was reported as high as 900 bph with a final TD at 11,050'. The drill string became stuck at 9850' while attempting to control loss circulation. Subsequently fishing operations failed to retrieve the drill string which was backed off at 9297'. The current forward operations are to set a balanced cement plug f. rom the top of the fish at 9297'(8726' TVD) to 8838'(8340' TVD) which is 300' above the Sag River kick off point at 9138'. This will cover the top 87' of the Shublik and completely cover the exposed Sag River. The cement plug will be Halliburton's Premium(G) with a volume of 17 bbl / 95 ft3 / 81 sks of 15.8 ppg and a yield of 1.18 cu.ft/sack. Should you have any questions please feel free to give me a call. Sincerely, C.

Michael Jackson S-11Ai Cement Bond Log BP Exploration I ARCO Alaska Inc, Date: November 12, 1998 Mr Wondzell, There has been quite a lot of discussion in Shared Services Drilling on the upcoming S-11Ai injection sidetrack and others such as M-12Ai and S-24Ai, for cement bond logs across the 4.5" production liner to produce compliance with AOGCC regulations. The original wellbore, S-11, has a 1982 cement bond tog showing 182' of bonded cement above the Sag River top. The planned kick off point for S-11Ai is in the Sag River at 9147' md. If we run a CBL in the new 4.5" liner it would only show us cement in the liner lap and cement from the Sag, Shublik and Zone 4 since the well is horizontal. There would be no additional confirmation of isolation of injected fluids to the productive horizons. Please review the figure below and comment on same. C.

Stuck pipe while drilling the Kingak has been reported in offset wells, however, the Kingak will not be penetrated. Lost circulation has been reported in the Sag River, Shublik and Ivishak production intervals. Three to five minor 10'-30' faults will be crossed in the polygon. Only minor losses are expected, however, potential for higher losses is possible and will need to be monitored closely. Shallow gas (Ugnu, W. Sak) will not be penetrated. Put River (gas) will not be penetrated. Kingak will not be penetrated. Disposal Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drilling operations to CC-2A for disposal. S-11Al Summary of Operations Pre-Rig Operations: The objective of the pre-rig work is to ascedain the condition of the 9 5/8" casing presently in the hole; P&A the existing perforations; chemical cut existing tubing in the first joint above production packer; and test the 9 5/8" pack offs. 1.

Stuck pipe while drilling the Kingak has been reported in offset wells, however, the Kingak will not be penetrated. Lost circulation has been reported in the Sag River, Shublik and Ivishak production intervals. Three to five minor 10'-30' faults will be crossed in the polygon. Only minor losses are expected, however, potential for higher losses is possible and will need to be monitored closely. Shallow gas (Ugnu, W. Sak) will not be penetrated. Put River (gas) will not be penetrated. Kingak will not be penetrated. Disposal Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drilling operations to CC-2A for disposal. S-11Al Summary of Operations Pre-Rig Operations: The objective of the pre-rig work is to ascertain the condition of the 9 5/8" casing presently in the hole; P&A the existing perforations; chemical cut existing tubing in the first joint above production packer; and test the 9 5/8" pack offs. 1.
