Holt, CTD Engineer Date: September 29, 2005 Re: Prep Prudhoe E-21A for CTD sidetrack Sundry approval is requested to prepare E-21A for a sidetrack. E-21A was a horizontal sidetrack. This well has add-perfs that resulted in gas and subsequently shut off. Acid treatments were attempted; the benefits were short-lived, thus sin -21A to become a cycle well. The well cycled with its twin, E-19A, until 10/04 when the wells wer de-twO n~ed, each well flowing separately. E-21A's cycle behaviour was poor with minimal on- time. The we /" mained a cycle well to date. The sidetrack, E-21B, is scheduled to be drilled by Nordic 1 during the last week of October. The plan calls for running a cmp above the existing perforations prior to setting a whipstock for an exit into Zone 2. E-12B will target Zone lA production. The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. Pre-IDe: Work 1. Set DGL V Done 12/09/03 2. Confirm pressure integrity. Done 09/20/05 3. Dummy whipstock drift . 4. Set cmp ~ 10,450' MD. Well bore de~on at 58 deg. / 5. Set WFD LSXN 'hipstock with TOWS at 10,400', low side exit. 6. Bleed gas lift and production flowlines down to zero and blind flange 7. Remove wellhouse, level pad. The pre CTI?. w~rk is slated to begin approximately Oct. 10.2005. \ \;vV.. I 0 - A 0 .~ ~ f kì\l C\.. t . IDe: Work 1. MIRU Nordic 1 and test BOPE. 2. Mill 3.725' XN nipple to 3.8" 3.

Box 196612 Anchorage, Alaska 99519-6612 (907) 561-5111 Re: Defeated Surface Safety Valves at Wells M-23, E-16 and E-21 Well A-01 Pilot Not Correctly Reset Z ANNEX AUG 2 V, 200 Dear Mr. Norman: This letter is in response to the Commission's June 30, 2004 letter regarding the surface safety valves observed on Wells M-23, E-16 and E-21 during June field inspections. You requested an explanation for why the surface safety valves (SSVs) on these three wells were defeated and our action plan to prevent reoccurrence. BPXA assembled a team of 13 operators and maintenance technicians to review events, possible causes, and develop preventative action plans. Preventative actions include: • Strict enforcement of accountability regarding adherence to SVS practices and administration of disciplinary action in each of these events. • Change -out of valve type to improve visual identification of valve position. • Stringent controls to ensure that SSV systems are correctly set and either secured in the proper position or clearly marked when they are closed. A summary of the team's investigation and findings into the specific events, and an action plan follows: Blocked SSV at Well M-23 One of the needle valves on the main hydraulic line between the hydraulic panel and the actuator of the SSV was found closed during miscellaneous State Testing on June 12, 2004. This prevented the hydraulic oil pressure from being bled -off when the pilot was tripped, thereby preventing the SSV from closing. The hydraulic valve was tie -wrapped in the closed position. Chairman John Norman July 29, 2004 Page 2 Explanation: M-23 was shut in as part of an M -Pad shut down on May 9, 2004, to perform various maintenance activities. While the hydraulic needle valve in question would not typically be closed when the well is shut in, we suspect that it was closed during this time. Activities that could have required the closure of the needle valve include well servicing, valve maintenance, and corrosion monitoring work or use of the well to blow down header pressure. The exact reason for, or date of, closure of the hydraulic needle valve is not known. It is apparent that the needle valve was inadvertently tie -wrapped in the closed position. There are a number of different styles of needle valves used in this service. The length of the stem varies significantly; so an operator cannot tell by looking whether valve is open or closed. Black cable ties are often used to secure the valve in an open position, so if a valve has a black cable tie, an operator can tell by looking that the valve is in the in the proper (open) position. In this case, the valve was erroneously tie -wrapped in the closed, instead of open, position. This indicated (incorrectly) to the operator that the valve was open, and the operator likely did not believe that further verification was needed. Blocked SSVs at Wells E-16 & E-21 During miscellaneous State testing on June 18, 2004, the hydraulic supply block valves on two control panels were found in the closed position, preventing the surface safety valve from closing when the pilot was tripped. Explanation: The valves in question are located on the control panel and are not used by operators on a routine basis. As in the case of the M-23 well, there are a number of other groups that may have used these hydraulic valves to isolate the SVS during their work. While the cause of the inadvertent valve closures remains uncertain, it is apparent that the valves were not verified to be in the proper open position by the operator as is required by the operator during daily rounds. The defeated valves, however, were not tie wrapped nor had they been flagged to indicate they were in the closed position. As in the scenario with Well M-23, the design of the valve is such that visual observation of the valve does not allow for clear indication of the valve position. A-1 Well On July 16, 2004, while testing well A-01, it was discovered that the pilot was not properly reset which resulted in an additional defeated surface safety valve. As discussed with AOGCC staff on July 26th, we are including the explanation and preventative actions for this event as part of our overall action plan. Chairman John Norman July 29, 2004 Page 3 Explanation: The reset switch on A-01 had a "toggle" feature that required the operator to pull the switch and "toggle" the switch open until the nitrogen supply pressure reset the pilot. Once the pilot had been reset, the operator was required to close the toggle switch. The reset switch was inadvertently left in the "toggle -on" position defeating the SVS. A -Pad had been shut down during the GC -3 turnaround, July 9 — 13, 2004. Several operators assisted in bringing A- Pad back onto production, some of which were not familiar with the unique requirements of this toggle switch. With the number of operators involved and the primary operator's attention divided among a number of priority items requiring verification, the reset switch was overlooked. Preventative Actions: These incidents indicate a need for reinforcement and improvement in 3 areas: 1) accountability for SVS practices, 2) improving the ease of identification of hydraulic and control valve position, and 3) the control of operations of the valves to prevent the improper movement of the valves by someone other than the responsible operator. This will be accomplished through the following actions: 1. Accountability will be reinforced through disciplinary action. Documented verbal warnings to the 3 responsible pad operators have been administered and BPXA's expectations regarding the need and importance of proper SVS procedures were reinforced. 2. Identification of valve position will be improved through change -out of hydraulic needle valves to quarter -turn valves. The two needle valves on the main hydraulic lines of M Pad wells will be evaluated for replacement with a single quarter -turn plug valve. This change will reduce the number of valves that could potentially be left in the incorrect position and provides an easily conclusive visual indication of the correct valve position. A Management of Change (MOC) evaluation will be conducted to ensure that one valve is an acceptable modification to the system. 3. Pending completion of the MOC, this modification will be implemented at M Pad and a schedule established for implementation at remaining well pads in the western operating area where similar SVS configurations exist. 4. Availability of a locking device that can be applied to the quarter -turn valves will be evaluated to ensure operators can retain control of the valves. A Chairman John Norman July 29, 2004 Page 4 5. Control and identification of valve position will be improved on control panel valves (similar to those on E-16 and E-21) either through application of tie -wraps or use of flagging. 6. All pilot configurations similar to A-1 have been inspected and all toggle pilots (two were identified) have been replaced with the more common reset switches. Finally, your letter stated that that the failure rates for the (June) tests of M and E -pads resulted in a component failure rate in excess of 10% and that increased testing frequency would be required. As discussed with AOGCC staff, the tests on these pads in June were comprised of a small number of wells (4 at E -pad, 7 at M -pad) that had been shut in during the prior months "routine" scheduled tests. When the results of these "miscellaneous" tests are combined with the routine tests (15 wells at E -Pad in April, and 13 wells at M -Pad in May) a more representative measurement of overall performance is obtained. The resulting combined failure rate at E -Pad is less than 10%, while it is greater than 10% at M -pad. Following discussion with AOGCC staff on this issue, we recommend that the E -pad well testing program remain on the existing 180 day test frequency while the M -pad test frequency is increased to 90 days until acceptable performance is achieved If you have any additional questions, please do not hesitate to contact me at 564-5671 or Bruce Williams at 564-4632.

MORKOWSKI, GOVEPIVOR 333 W. 7r' AVENUE, SUITE 100 Ar CHORAGE, ALASKA 99541-3539 PHONE (807) 279-1433 FAX (967) 276.7542 On June 12 and 18, 2004, Alaska Oil and Gas Conservation Commission ("Commission") inspectors, accompanied by a BPXA representative, performed safety valve system ("SVS") inspections at Prudhoe Bay M- and E -pads, respectively. Commission inspectors noted that the surface safety valve ("SSV") on `]yells M-23, E-16 and E-21 had been blocked at the control panel some time prior to the inspections, preventing each well's SSV from operating. Copies of the inspection reports are attached. You are reminded that Conservation Order No. 363 (Prudhoe Oil Pool), Rule 5 modifies the requirements of 20 AAC 25.265 ("Automatic Shut-in Equipment") as follows: (a) Each well shall be equipped with a Commission approved fail-safe automatic surface safety valve system (SYS) capable of preventing uncontrolled flow by shutting of) flow at the wellhead and shutting down any artificial lift system where an over pressure of equipment may occur. (b) The safety valve system (SYS) shall not be deactivated except during repairs, while engaged in active well work, or if the pad is manned. ff the SYS cannot be returned to service within 24 hours, the well must be shut in at the wellhead and at the manifold building. 1. Wells with a deactivated SYS shall be identified by a sign on the wellhead stating that the SUS has been deactivated and the date it was deactivated. 2. A list of wells with the SYS deactivated, the dates and reasons for deactivating, and the estimated re -activation dates must be maintained current and available for Commission inspection on request. t&ANNEt JvI_ I' 200: Ms. Maureen Johnson June 30, 2001 Page 2 of 2 Conservation Order No. 363 replaced the requirements of earlier Conservation Order No. 341 (Prudhoe Oil Pool) pool rules by providing for the elimination of subsurface safety valves ("SSSV") in certain wells. The elimination of the SSSV in Prudhoe Bay wells increases the reliance on the surface safety equipment. The facts reported by our inspectors appear to indicate a failure to maintain an operable SVS in each well, which is a violation of Commission regulations. Within 30 days of receipt of this letter, you are requested to provide the Commission with an explanation of how these events happened and what will be done in the future to prevent its occurrence in BPXA-operated fields. We note that this is the fourth such letter sent to BPXA since July 2003 regarding defeated safety valve systems at BPXA-operated fields. Also noted during the inspections of M- and E -pads were SVS component failure rates of 21 and 25 percent, respectively. Commission policy, as outlined in a letter dated November 14, 1995, states that the testing frequency will be increased when a failure rate exceeds 10 percent. Effective the date of inspections, and until an acceptable level of performance is achieved, the safety valve systems associated with wells located on PBU M- and E -pads must be tested every 90 days. When testing is scheduled, you must notify the Commission field inspector at 907-659- 2714 to provide an opportunity to witness the SVS test. The Commission reserves the right to pursue enforcement action in connection with these apparent violations as provided by 20 AAC 25.535. Should you have any questions regarding this correspondence, please contact Mr. James Regg at ( 907) 793-1236.

I arrived to find the rig ready to test. All BOPE equipment was tested and passed with the exception of the isolation valve for the choke panel sensor, which leaked and had to have the valve changed. The rig and its surrounding area were well kept and provided good access. Tim Krupa (Doyon Toolpusher) uses a sure and methodical test procedure that provides for a good test of the rigs BOP equipment. SUMMARY: ! witnessed the initial test of the BOPE on Doyon rig #9 drilling BPX well #E-21A in the WOA of the Prudhoe Bay field. There was one failure observed. Test time 4 hours.
