Request: Sundry approval is requested for plans to restore tubing integrity. History and current status: Well S-41 was drilled as a multi lateral completion in 1997 with L-80 liner and tubing. The original tubing is still in the well. The well has a history of failing TIFLs. The well has had two tubing leaks since the well was originally completed. The first tubing leak was at station 1, and was squeezed in 2009. The well was operable from that point until 2014, when it failed another MIT -IA. The second leak was identified at station 2 and was patched. In 2017 The well was found to have IA pressure over normal operating limits, due to failed SO check valves. Slickline performed a caliper which indicated multiple areas of corrosion, with most severe penetration at 4645' MD. A plug was set at 8867' MD, and a CMIT-TxIA was performed in December of 2017 to 2395 psi. An attempt was made to set a dummy valve in station 3, with no success. A second plug was set above station 3, and the tubing was tested to 2417 psi. The source of TxIA is believed to be in stations 3 and 2. Proposed plan: 11 The CDR2 rig will swap the tubing to restore tubing integrity. MASP = 2520 psi. CDR2 BOPE will be configured as follows (BOP schematic attached for reference): • One Annular preventer • One Blind Ram -type preventer • Mud cross with outlets for choke and kill lines • One VBR preventer. Testing will be in accordance with State and BP policy of a 7 day BOP test. Testing will be 3500 psi high and 250 psi low for all components. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of both the current and proposed wellbore is attached for reference. Scope of Work: The primary objective of this RWO is to replace tubing to restore tubing integrity. Pre -Ria Prep Work: 1. V: PPPOT-T, PPPOT-IC. Cycle LDS. 2. F: CMIT- TAA to 3000 psi, OA Integrity test. 3. E: Cut Tubing at -8800' MD 4. F: CMIT-TxIA to 1000 psi. Circulate out well. 5. V: Install BPV. Install dry hole tree 6. O: Bleed WHP(s) to zero. Remove the well house and flow line. Install wellhead valves as needed. Install dry hole tree. Level the pad as needed. Proposed RWO Procedure: 1. MIRU. ND tree. NU and test BOPE to 3500 psi 2. Pull 4-1/2" tubing from pre -rig cut at -8800' 3. Run new 4-1/2" 13 -CR Stacker Packer Completion. 4. Freeze protect well. Set TWC. ND BOPE. NU and test tree. RDMO. Post ria Work: 1.

The source of TxIA is believed to be in stations 3 and 2. Proposed plan: The All American Oilfield 111 pulling unit will swap the tubing to restore tubing integrity. MASP = 2520 psi. AAO 111 BOPE will be configured as follows (BOP schematic attached for reference): • One Annular preventer • One Blind Ram -type preventer • Mud cross with outlets for choke and kill lines • One Ram -type preventer dressed with Ram or VBR depending on what pipe is being ran/pulled. Testing will be in accordance with State and BP policy of a 7 day BOP test. Testing will be 3500 psi high and 250 psi low for all components. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of both the current and proposed wellbore is attached for reference. Scope of Work: The primary objective of this RWO is to replace tubing to restore tubing integrity. Pre -Rig Prep Work: 1. V: PPPOT-T, PPPOT-IC. Cycle LDS. 2. F: CMIT- TxIA, OA Integrity test. > 3. E: Cut Tubing at -8800' MD p \ 4. F: CMIT-TxIA. Circulate out well. 5. V: Install BPV. Tree Work u 6. O: Bleed WHP(s) to zero. Remove the well house and flow line. Install wellhead valves as needed.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10-404, Report of Sundry Operations.

The permit to drill does not exempt you from obtaining- additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. The permit is for a new segment from existing well S43, Permit No. 97-52, API No. 50-029- 22754. Production should continue to be reported as a function of the original well identifier. Blowout prevention equipment (BOPS) 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.

S-43 / S-431-1 Permit Info Page 4 Drilling Hazards • Hydrocarbon -bearing zone in the Ugnu formation. • Losses have been encountered drilling the Kingak, Sag River/Shublik and Sadlerochit formations on S Pad. Be prepared for losses near any faults and formation interfaces between the Kingak, Sag River/Shublik and Sadlerochit. • A minimum of 10.0 ppg mud weight will be used to drill the Cretaceous injection interval. This will allow a 100 psi trip margin over the expected 9.4 ppg EMW @ 5000' TVDss. Disposal Cuttings Handling: 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 cutting from drilling operations to CC - 2A for disposal, except the metal cuttings which will be sent to the North Slope Borough.
