The permit is for a new wellbore segment of existing well E-11 B, Permit No. 206-143, API No. 50-029-20475-02. Production should continue to be reported as a function of the original API number stated above. In your application you identify a contingency that must be addressed in advance. If lost circulation or unstable hole is encountered, it may be necessary to partially cement the liner of this wellbore. Should this happen, cementing the upper portion of the liner will abandon the existing perforations in the main E-11 B wellbore. Abandoning these perforations will result in an important change: the planned E-11 BL 1 multilateral will instead become a redrill named E-11 C. To ensure clear record keeping and statistical reporting, a new permit to drill and a new API number wili be required for E-11 C, and this permit for E-11 BL 1 will be cancelled. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to 'vvi~ii~iaLi% ~jic j~ciiiii~ 3i1 ~~t3~ ZvCfll`, li W~S e2'Z'0I1e0USly 2SSUeC1.

S. Endacott BPAlaska CTD Engineer Date: Apri126, 2007 Re: E-11B L1 and L1-O1 CC: Well File Sondra Stewman/Terrie Hubble bp E-11 was originally drilled in 1994 and completed in Zone 2 of the E-K Graben. After the well had reached marginal GOR the well was recompleted into the Sag with 70 feet of open hole. In 1997 the well was sidetracked to a Sag target that was northeast of the original well. This was done because the well had high GOR and was on less than 10 percent of the time. E-11 A was drilled in October 1997 and was on fulltime for the next 2 years producing. The well was shut-in January 2000 for high GOR. The well was brought back on in October 2000 and showed signs of the oil rate healing, but the gas rate had not decreased and resulted in the well being above marginal. When the well was screened for a CST it was discovered that the well had collapsed tubing. E-11 A was then secured while it awaited the E-pad Production Optimization Project and a RST. The well was twinned with E-38, a producer into the high pressure (HP) header. In December 2004, the E-pad Production optimization project was completed and now both wells have access to a new high pressure trunk line. Operations now have the option to produce through this high pressure line or through the original6" line. REASON FOR LATERALS: In November 2006, a pilot hole (E-11B) was drilled to evaluate the Ivishak and SAG Pavlov prospect. The logs indicated that the Ivishak is wet and the SAG is hydrocarbon bearing verifying our expected case. Post RST eline perforated 50' of vertical SAG. Due to the limited length of perforations in a vertical hole operations was unable to kick off and test the well. A Static pressure survey was run on 3/12/07 that verified the Pavlov block is in pressure communication with the rest of Prudhoe. It is recommended that we proceed with a mulitlat horizontal CST into the SAG to effectively drain the Pavlov fault block. The laterals are planned on or around June 2007. The laterals, E-11BL1 and BL1-O1, will exit the existing 4 1/2" liner and kick off in Sag River zone and target Sag. The existing perforations will be left open to flow and both laterals will be completed with slotted liner. However there is a contingency cemented liner in the event of lost circulation or wellbore stability issues; in this instance, the lateral names will be changed to E-11C and E-11CL1. The following describes work planned. A schematic diagram of the proposed sidetrack is attached for reference. Pre-Rig Work: 1.
