Basically, we are changing the order of the cmt plug pumping & milling of the casing patch. We just felt it was better to P &A the open perforated interval before we start messing with the casing patch. I also reduced the 9 -5/8" casing test pressure from 1500 psi to 1000 psi, to try and avoid making an issue out of the problem at 157' in the 9 -5/8 ". We are going to set a tie -back on this well as we did on M- 29A. 1000 psi will be provide enough shut -in integrity while drilling the section. Let me know if this is acceptable to you. If you will approve verbally, I will submit the official 10 -403 "Change to Approved Procedure ".

When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). 2. On the Form 10 -403 if "Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve D. will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10 -403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10 -407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re -drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10 -407. Steve will also change the status on the 10 -407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10 -407 into RBDMS. 5. When the Form 10 -407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accuracy.

When a Form 10 -403 is submitted requesting approval to plug a well for redrill, the initial reviewer (Art or Steve D.) will check to make sure that the "Plug for Redrill" box in the upper left corner of the 403 i/ form is checked. If the "Abandon" box is checked, we will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). 2. On the Form 10 -403 if "Abandon" is checked in Box 15 (Well Status after proposed work), Art or Steve / D. will cross that erroneous entry out and initial it on both copies of the Form 10 -403 (AOGCC's and operator's copies). Instead, we will check the "Suspended" box. Guy and Winton will serve as quality control for steps 1 and 2. 3. When Steve McMains receives the Form 10 -403 with a check in the "Plug for Redrill" box, he will enter the existing code "IBPRD" into RBDMS. This code automatically generates a comment under the History tab stating "Intent: Plug for Redrill." 4. When Steve McMains receives any Form 10 -407, he will check the History tab in RBDMS for this comment. If he sees the "Intent: Plug for Redrill" code, and cannot find any evidence that a subsequent re -drill has been COMPLETED, he will assign a status of SUSPENDED to the well bore in RBDMS, no matter what status is listed on the 10 -407. Steve will also change the status on the 10 -407 form to SUSPENDED, and will date and initial his change. If Steve does not see the "Intent: Plug for Redrill" comment or code, he will enter the status listed on the Form 10 -407 into RBDMS. 5. When the Form 10 -407 for the redrill is received, Steve M. will change the original well's status from suspended to abandoned. 6. The first week of every January and July, Steve M. and Steve D. will check the "Well by Type Work Outstanding" user query in RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, Steve M. and Steve D. will also review the list of suspended wells for accuracy.

Wells M-25, M-29 and M-31 were tested. Mr. Grimaldi arrived on Steelhead Platform and found the wells shut in and depressurized as requested. Over the course of 3-1/2 hour witnessed period, test performance of TBU Well M-25, PTD 187-086, TBU Well M-29, PTD 191-027 and TBU Well M-31, PTD 193-190 demonstrated only minor amounts of gas. When shut in, only slight pressure increases were noted which could be quickly bled off. Therefore, these wells need not be equipped with a commission approved fail-safe automatic surface-controlled subsurface safety valve ("SSSV") system. However, these wells must be equipped with fail-safe automatic surface safety valve ("SSV") systems capable of preventing uncontrolled flow and maintained in proper working condition. If for any reason any of the wells become capable of unassisted flow of hydrocarbons, the SSSV must be returned to service. A copy of this letter should be maintained in the respective well files on board Steelhead.

NON-CONFIDENTIAL CC; Dwight'Johnson/Gary Ross (Unocal) Atta...chment: None No-Flow UNOCAL TBU M~25,29,31 4-11-01 LG STATE OF ALASKA ALASKA OIL AND OAS CONSEI~VATION COMMISSION. FIELD OPERATION PROCEDURE Procedure: "No-flow" test to demonstrate that a' well is not capable of unassisted flow. · Purpose : Removal of downhole safety valve. Authori.ty: Regulation EO AAC E5.265(a) Effective: May 1, l~e Approved : Blair E. Wondzell, Pet Ins Supervisor. File No. : F-OP-SVAO. PURPOSE: Regulation 20 AAC 25.265 AUTOMATIC SHUT-IN EQUIPMENT (a) requires that a completed well with a offshore surface location which is capable of unassisted flow of hydrocarbons must be equipped with a commission aporoved...2) fail-safe automatic surface controlled subsurface safety valve (SSSV) system, .... (b) The commission will, in its discretion also require ...SSSV's on wells in other areas. The purpose of the "no-flow" test is to demonstrate that a welI ~i~ not capable of unassisted flow of hydrocarbons so that the SSSV can be removed. (Note, once removed, the SSSV must be reinstalled if the well again becomes capable of unassisted, flow of hydrocarbons). · PROCEDURE: Prior to the petroleum insDector's arrival, the artificial lift system must be shut off and the well bled down as appropriate - this could take several hours if its on gas lift. The'initial bleed down will be to the separator, then to an atmosphere tank or vessel. After the system has been bled down, the commission requires a three 43) hour witnessed period of "no-flow"; maximum permissible hourly flow rate (based on API ~P 1qB) is ~00 SCF or &.3 gallons. There are various ways "no-flow" can be demonstrated~ two methods are as follows: 1. Shut-in the tubing and monitor the tubing pressure build-up on a recently (3 mo. max.) calibrated chart recorder of not over 250 psia. full scale capacity. At intervals of I to 3 hours, open the flow line~ if the pressure is discharged in up to about five minutes~ the well is not capable of unassisted flow. ~. Keep the tubing open for flow into an atmospheric pressure vessel~ preferably open top, that is small enough so that small volumes can be detected. If total gas and fluid produced is less then API standards for "leakage rate*' as listed above, the well has demonstrated "no-flOw". "NO-FLOW DETERMINATION": The official notification of the results of a "no-flow" test will be by ietter from the P.I.Supervisor or a commissioner, a~ter which the SSSV may be removed from the well.

Sunday, June 12t 1994: I traveled to Marathon's Steelhead platform to witness the weekly BOP test on their rig which is presently redrilling M-31. The rig was not ready when I arrived. I made a cursory tour of the platform and randomly checked the SVS systems, I found all to be operational and in good condition. The test once started went very well with all components functioning properly and holding its pressure test. The test lasted 4 hours due to Richard Kennedys (Pool Toolpusher) diligence and in depth testing procedure. I found the overall condition of the platform and rig to be in outstanding shape. Summary: I witnessed the weekly BOP test Marathon's Steelhead platform. Test time four hours. No failures. Attachment: AU7JFLBD.XLS cc: Mark Sinclair (Marathon drlg supt.)

TBU P.T.D. 93-190 Sunday May 23, 1994: I traveled to Marathon Oil Co.'s Steelhead Platform to witness a BOP test on the Steelhead Rig. The AOGCC BOP Test Report is attached for reference. The Steelhead Rig has been out of use for the past 2 years. Although the rig has not been used for some time everything seemed to be in very good shape With a few minor exceptions. The swivel packing on the top drive unit leaked, I manual choke line valve failed and waS replaced and the IBOP on the top drive was out of adjustment these items were repaired and testing was completed. The accumulator time tests were somewhat longer than they should be, but were not out of compliance. Lance Lamons Marathon's Rig Rep. assured me that the accumulator would be repaired so a better time test could be achieved. Summary: I witnessed the BOP Test on Marathon's Steelhead Rig with I failure, 27 valves tested, 6 hours.

The rig was not ready when I arrived, I made a cursory inspection of the equipment and stood by until the following morning. The function test went fairly well with two minor problems, these being the hydraulic lines for the vent line valves were reversed which caused the South line to open when the North line was selected and vice-versa. This problem was identified and Corrected quickly. Also the accumulator was Iow on hydraulic fluid which was attributed to the rig just starting up and filling the lines and 30" · Annular preventer. All in alii found the rig to be well prepared and in good shape for drilling surface hole.

Attached is a list of outstanding Permits to Drill issued to your engineering group (permits for Which no form 10-407 has been received by this office). Please review this list to determine if any of the wells were drilled in 1993. If so, please note the well name, total measured depth, and class (development, service or exploratory), if any wells were drilling as of 12/31/93, estimate the depth at 12:00 midnight. We would appreciate your reply by the end of January if possible. Thank you for your cooperation with this project. If I may be of any assistance, please call me at 279-1433.

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. 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 at 279-1433. David W. Chairman BY ORDER OF THE COMMISSION dlf/Enclosures cc: Department of Fish & Game, Habitat Section w/o encl.
