Jones" <jeffjones@admin.state.akus> Organization: AOGCC To: Winton GAubert <winton_aubert@admin.state.akus>, Tom Maunder <tom - maunder@admin.state.akus> Hello Winton and Tom, I just wanted to make you aware of a situation regarding the ongoing sidetrack being performed on well W-15A (PTD 202-151). I was out there this morning for a BOP test and while talking to the Nordic 2 personnel, I was told that they apparently drilled into the 4.5"x7" packer while drilling out the first whipstock they set (11,845 MD+/-). A second whipstock was set (11,786 MD+/-) and they are continuing the operation from there. I questioned them as to whether or not they planned to cement the subsequent liner and was told it hadn't been determined yet and would depend on water content in the formation. In reading the well plan it listed 3 completion options: cemented liner, uncemented slotted liner or Bonzai completion. The plan also mentioned a previously known 4.5 x 7 IA communication (I can't find this well on the list of Prudhoe wells with communication from BP and Jim doesn't have anything on it either). This well has 5 dummied GLM's that may be suspect. Since the rig is on the well, is this a good time to find the leak / repair it? Should the liner they run be cemented? I appreciate your thoughts, Jeff J TONY KNOWLES, GOVERNOR AItASIiA. OIL AND GAS CONSERVAnONCO~SSION 333 W.

The permit to redrill does not exempt you from obtaining additional permits or approvals 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 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 Commission 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 a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

Attachments Date 7A?IO~ Submit In Triplicate -) ) / BP W-15a CTD Sidetrack Summary of Operations: / A CTD through tubing sidetrack is planned for W-15. The coilßidetrack, W-15a, will exit the 41/2" tailpipe x 7" liner in the Ivishak Zone 4 formation and target Zone 48. I' W-15 was completed in 1990 with an experimental uncemented liner that utilized external packers for zone isolation and sliding sleeves for selective production. Perforations were later added throughout the Zone 4 section to insure full formation access but production remains low. The sidetrack, W-15a, will target the most productive intervals, the 46-44P sands, to improve productivity and provide offtake in conformance / with the MI being injected in W-03ai. The sidetrack will be completed with an uncemented, pre-drilled liner. One small E/W trending fault will be crossed in W-15a but the fault orientation and regional history indicate a very low risk of lost circulation. GR/Resistivity logs will be run while drilling to measure water saturations. I Phase 1: Prep work. Planned for between August 5 to August 15, 2002. 1. Dummy all GLM's and perform an MIT-IA. 2. Set a cast iron bridge plug at approx.11 ,860' (8870ss) to isolate the uncemented liner. 3. Set a flow through whipstock in the 4 Y2" tai~e at approx. 11,810 (8853ss). /' 4. Service coil will pump a minimum of 20 bbls 15.8 ppg cement to stabilize the 4 Y2" tailpipe for window milling. Phase 2: Mill window, Drill and Complete sidetrack: Planned for August 25,2002. Drilling coil will be used to mill the window through 4 Y2" and 7" , and through existing perforations, then drill and complete the directional hole as per attached plan. Maximum hole angle will be 98 degrees. Mud Program: /" . Phase 1&2: Seawater and 8.6 ppg Flo-Pro . Phase 3: Mill and drill with Flo-Pro (8.6 - 8.7 ppg) Disposal: /' . All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. / . All Class I wastes will go to Pad 3 for disposal. Casing Program: The production liner will be a 3 3/16" TC II x 2 7/8" ST-L solid and pre-drilled liner from TD to approx. 11,750' MD (8827ss). The X-O between 3 3/16" x 27/8" will be at 11 ,870jMD (8873'ss). Well Control: . BOP diagram is attached. I . Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. . The annular preventer will be tested to 400 psi and 2500 psi. Directional . See attached directional plan. Max. planned hole angle is 98 deg. . Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging . An MWD Gamma Ray/Resistivity will be run over all of the open hole section. Hazards . W Pad has no production with H2S in excess of 10 ppm. The closest BHL wells, W-01 and W-04, have H2S measured at 10 ppm. ) ) . Lost circulation risk is considered to be minimal based on fault orientation and regional history. Reservoir Pressure Res. press. is estimated to be 3550 psi at 8900'ss (7.7 ppg emw). Max. surface pressure with gas (0.12 psi/ft) to surface is 2482 psi. / ) TRæ= W8..LI-EAD = ACTUATOR = KB.
