The complete 403 approved packages are attached to this e-mail for reference. Our rationale is as follows: 1. The MITOA typically will not pass conventional pressure test criteria (30 minute test with 10% pressure loss) due to the extremely small volume we are trying to test in a fully cemented OA. The 30 minute test criteria was designed for a large volume (un-cemented,fluid packed tubing or casing and associated annuli). 2. Due to point#1, BP does not consider a passing"MITOA"to be the appropriate measure of success or failure of the repair. 3. BP proposes that the indicator for job success will be bringing the well online under evaluation and monitoring the conductor for any leak,weep, etc. as well as monitoring any thermal pressure buildup in the small void space in the OA daily. 4. In the future, BP will submit Sundries for these types of repair without an MITOA included for the above reasons. • If you agree, could you please respondtthis e-mail with "approved" or"agreed"?

After the casing cut and pull, cementing the OA to surface the well was put on production and the parent surface casing leak was rediscovered. > 11/27/15: RWO Complete > 12/09/15; MIT-T Passed to 2988 psi, MIT-IA Passed to 2947 psi > 12/10/15: Set LGLV in sta# 6, OGLV in sta# 5 > 12/13/15: Pulled TTP from 9624' MD > 03/28/16: Found leak point in SC @ 26" below OA casing valve Objectives Perform an OA microfine cement repair squeeze to remediate the rigworkover casing cut and pull cement work and return the well to operable status. Procedural steps Specail projects/DHD 1. Strap TOC and hot water/surfactant wash the OA, until clean returns are observed. Remove water/surfactant. 2. Strap top of cement in the conductor by surface casing annulus and fill, bottoms up, the void with microfine cement until clean returns are observed at surface. Pressure up with microfine cement until clean microfine cement returns are taken in the conductor or up to 2500 psi, bump pressure three times. Cap with 500 psi of nitrogen. 3. Wait on cement to cure. 4.

In Sept'96, CTD drilled out the toe of the slotted liner and crosscut the Zone 4 section. The drill out was completed with 2-7/8" slotted liner. S-40A started having problems in 2002 when the Pad Operator noticed diesel coming up the conductor pipe. The failing MIT-T and IA tracking indicates communication from the tubing to the IA. This will be resolved with the new tubing completion. The failing MIT-OA to N2 confirmed the SC leak and will be resolved by cementing the 7-5/8" production casing to surface. Scope of Work: The primary objective of this RWO is to restore well integrity and return the well to / operable status. Pre Rig_Prep Work: W 1 Check the tubing hanger lock down screws for free movement. PPPOT-T&IC. F 2 CMIT-TxIA to 3000 psi.

The tubing leaks were logged with a leak detect log on 3/3/15 and found at 7780' and 8439' MD.The production casing is good as the well passes a CMIT-TxIA to 3000 psi. So the pressure is on the OA and we will repair that by cutting and pulling the 9-5/8" casing and cementing new casing in place to surface. .

The permit to re-drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting re-drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling a new hole. Notice may be given by contacting the Commission's petroleum field inspector on the North Slope pager at 659-3607. David .

Johnston Submit in triplicate BPX S-40 Sidetrack 7/1/96 Summary of Operations: Well S-40 Kv/Kh is not allowing good waterflood or vertical sweep to occur with the horizontal well configuration. The extension drops the well down throughout Zone 4 and provides offtake for conformance. Drill Directional Hole: Planned for July 15-20, 1996. - Directional drilling coil tubing equipment will be rigged up and utilized to ddll the directional hole as per attached plan to planned TD of 11,669' MD (8,766' TVD ss). Mud Program: - FIo-Pro (8.8- 8.9 ppg) Casing Program - 2 7/8", 6.16#, L-80, FL-4S Slotted liner will be run from TD to approx. 11,340' MD. Well Control: - See attachments. - Drilling operations will utilize the fully lubricated system shown in the attached diagram. - The production liner will be run using the 4-ram and annular preventer system shown in the attached diagram. - Pipe rams, blind rams and the CT pack-off will be pressure tested to 400 psi and to 4000 psi. - The annular preventer will be tested to 400 psi and 2000 psi. Directional - See attachments. Existing shoe to be drilled out: 11,366' MD (871 9' TVD ss) - TD: 11,669' MD (8766' TVD ss) Magnetic and inclination surveys will be taken every 25 ft. No gyro will be run. Logging - A Gamma Ray Icg will be run over all of the open hole section while drilling.
