Due to the fact the 9-5/8" casing is uncemented at the planned kick off point, there is potential to induce wellbore breathing in the CM formation when conducting the LOT. We would like to change the planned LOT to an FIT. To obtain a 25 bbl kick tolerance, assuming 10.3 ppg mudweight at the intermediate TD interval we need to achieve at least a 12.1 ppg EMW. We will target a FIT value of 12.6 ppg EMW, which will provide us a 25 bbl kick tolerance if we had 10.8 ppg EMW at TD. Although it is highly unlikely that it will be necessary to increase the mudweight above the planned 10.3 ppg, we wanted to apply a safety factor to ensure we are covered if that scenario were to occur. Please let us know is this change is acceptable and if you have any questions or concerns. Thanks, Brad Brad Gorham BP Exploration (Alaska), Inc.

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 AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or an AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

This rotary sidetrack is a horizontal producer targeting the Zone 1 Ivishak Sands. The planned well is a two string, ultra- slimhole design using a 9-5/8" surface casing, 7" intermediate casing, and 4-1/2" production liner. The intermediate casing will be set at the top of the Ivishak, and the production interval will be completed with a cemented and perforated liner. The maximum anticipated surface pressure from the Ivishak with a full column of gas from TD to surface is 2,457 psi (assumes 7.64 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 3,500 psi. A detailed operations summary is included with the permit application. If there are any questions concerning information on 11-23B, please do not hesitate to use the contact information below.

Intermediate Hole: The UG4 is expected to be a 9.5 ppg EMW. The CMI, CM2 and CM3 are expected to be 9.7 — 10.0 ppg EMW. Formation pressures will be controlled with a 9.8 — 10.3 ppg mud to drill to within 200' MD of the CM1. At this point, there will be a weight up to 10.3 — 11.0 ppg to drill the rest of the interval to TD. B. Production Hole: The Ivishak is expected to be at a 7.6 ppg EMW. Reservoir pressures will be controlled by using 8.5 — 9.0 ppg water based mud. II. Lost Circulation/Breathing A. Intermediate Hole: There are no expected fault crossings in the first intermediate hole. However, breathing has been known to occur in the Colville on other Drill Sites in Prudhoe Bay as a result of high ECD's. B. Production Hole: There are no planned fault crossing in the production interval so the lost circulation risk is low. III. Fault Locations There are no planned fault crossings. IV.

The logging program on page 4 states that the production hole will be logged with Dir/GR/RES/NEU, but the planned drilling program on page 9 says the BHA will have MWD/GR/RES/DEN/NEU.
