(BPXA)'s explanation provided April 16, 2018 regarding the defeated well safety valve system on Prudhoe Bay Unit(PBU) W-02B. The Alaska Oil and Gas Conservation Commission agrees that recent actions initiated and ongoing by BPXA in response to a similar event appear adequate to prevent recurrence of defeated well safety valve systems. Agreed dates for quarterly meetings beginning in June 2018 provide the opportunity to monitor BPXA's progress implementing the corrective actions. The AOGCC does not intend to pursue any further enforcement action regarding the Prudhoe Bay Unit W-02B defeated safety valve system. Sincerely, Hollis S.

(BPXA) for a low-pressure pilot that was found defeated at the time of performance testing. Well W-02 was shut-in on August 13, 2016. The last AOGCC surface safety valve (SVS) test was conducted on August 8, 2016. Well W-02 was put on production on March 24, 2018 and an AOGCC SVS test was scheduled for March 25, 2018. During the AOGCC SVS test a valve to the low-pressure pilot was found to be closed. Interviews with Technicians that placed the well on production indicated that a function test of the SVS was performed when the well was put on production to assure that the SVS system would function. However, after completing the function test or during the AOGCC SVS test the valve was put in the closed position. Due to this event and the recent B-35 event, BPXA has initiated aP Y h sical validation of the SVS systems on all operating wells in the GPB Unit on March 26th. That validation effort was completed on March 29th with no additional issues identified. BPXA also initiated an investigation into the W-02 incident. That investigation has determined that the cause of the W-02 valve closure was a human error. This type of human error is similar to those identified in the B-35 investigation that was recently completed. BP respectfully proposes that this issue be addressed by the actions that have been initiated to close out the B-35 investigation. This event with the W-02 pilot has identified a modification that may be incorporated into the put on production (POP) procedure. We are considering adding two steps in the procedure. The first step BPXA Response to NO• • AOGCC Docket Number: OTH-18-024 April XX, 2018 Page 2 being documenting the pilot trip pressure during the function test and the second step being documenting the pressure to the pilot when the pilot is returned to service after the function test. These actions should ensure that the SVS is functional and that the pilot is sensing the well line pressure. If you have any questions, please contact me at (907) 564-5921 Sincerely, 42,44, f '1 Glen W.

(BPXA) at the Prudhoe Bay Unit W-pad. The low-pressure pilot on Prudhoe Bay Unit W-02B was found defeated at the time of performance testing. A copy of the inspection report is attached. The facts reported by the AOGCC Inspector indicate a failure to maintain an operable safety valve system, which would be a violation of State regulations. Within 14 days of receipt of this letter, you are requested to provide the AOGCC with an explanation of how this event happened and what has or will be done in the future to prevent its recurrence at BPXA-operated fields. Inspection revealed Prudhoe Bay Unit W-02B was producing prior to the performance test but the low-pressure pilot was rendered inoperable; the pilot was placed back in service during the inspection. You are reminded that 20 AAC 25.265 requires a completed well to be equipped with a functional safety valve system. Paragraph (m) establishes tagging procedures for a well safety valve system component that is inoperable, removed or blocked. There was no tag observed on Prudhoe Bay Unit W-02B that would indicate an inoperable low-pressure pilot.

Supervisor FROM: Matt Herrera SUBJECT: SVS Test Defeated Pilot Petroleum Inspector PBU W-026 BPXA PTD 2121590 Attachment to AOGCC Inspection Report#sysMFH180325164126 3125118: During miscellaneous SVS testing on PBU W-Pad, BPXA added producer PBU W-02B to the wells to be tested. Operations testing personnel installed their calibrated digital gauge on the low pressure pilot (LPP) tie in connection to obtain the flowing tubing pressure (FTP) and trip pressure. A 125 psi LPP was installed on this well with a 150 psi set pressure. The FTP was 240 psi. After getting the inner annulus, outer annulus and FTP pressures, a pressure differential was achieved. I witnessed the pressure bleed to test the LPP trip. When the bleed off pressure reached a fail status of less than 75 psi I had the pad operator continue to bleed the LPP to see the eventual trip pressure. The LPP was bled to 0 psi without tripping the SSV for closure. Upon further investigation it was determined the root needle valve from the S-riser manifold to the LPP switch was closed. LPP was defeated and well would not have shut in on a low-pressure event. The well components were reset and retested good. BPXA will try and make the determination as to how and when the pilot was defeated. Attachments: none 2018-0325_SVS_defeated_pilot_PBU_W-02_m h.docx Page 1 of 1 • • • .,,, , .
