MIT-IA Passed to 3000 psi (12/18/11) MIT-OA Pass to 1200 psi (2/14/15) PPPOT-T Passed to 5000 psi (2/16/15) PPPOT-IC Passed to 3500 psi (2/16/15) Well History: S-42 was originally drilled and completed in 1996 as a Zone 4 Ivishak producer. Production logs were run in 8/96 and again in 8/98. Both logs confirmed that almost all production was coming from a fault zone at 9930' md, even though almost 700' were perorated. There were several remediation jobs performed with no apparent production gain. The well is currently shut-in and has seen minimal on-time since 2005 due to subpar rates (99% WC) and has no remaining value or wellwork options. Scope of Work: The pre-rig P&A work for the S-42 well includes pump 2 cement plugs in the well (one to P&A the existing perforations as per the AOGCC requirements and one to provide the DPZ isolation as per our internal practice requirements) and a tubing cut. The rig-work for this well includes a cut and pull of the existing 7" casing at the current 9-5/8" casing shoe prior to a whipstock departure from the 9-5/8" surface casing just above the shoe prior to beginning the S-42A RST.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the Patricia or Steve upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" / boxes are also checked, cross out that erroneous entry and initial it on both ,/ copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Patricia or Steve work) the initial reviewer will cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, then V/ check the "Suspended" box and initial that change. Guy or Victoria The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug for Jenni Redrill" box, she will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, she will check the History tab Jenni in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, she will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will change Jenni the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Jenni Geologists will check the "Well by Type Work Outstanding" user query in Patricia or Steve RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy.

This well has since been shut in. I've attached a copy of a scanned email taken from the state's well electronic files sent May 18th reclassifying S -42 as a problem well. There have been no sustained casing pressure events for this well in the last four years since the May 18th 2007 reclassification. I have also attached a four year TIO plot. As per the attached re- classification email, this well was found to have sustained casing pressure on 05/01/07 and subsequently failed a TIFL on 05/10/07. The valves in this well were dummied but, when an MIT -IA failed on 05/24/07 the well was secured with a TTP. An LDL found a gas lift valve to be leaking on 08/02/07 but no subsequent wellwork commenced until recently. On 12/19/11, after changing out a gas lift valve, a passing MIT -IA was obtained. Jerry's email references the passing MIT -IA just obtained. Please let me know if you have any further questions. Thank you, Whitney King (Alt.

Commission Anchorage On October 28, 1998 you requested an update from Shared Service Drilling regarding Annular Disposal Records from July 25, 1995 through present time. We compared yOur list with our records and are able to provide yOu with the following data: · Individual Annular DiSposal Logs from the SSD database Which coincide with the approved wells on your attached AOGCC Annular Log. The SSD records are proVided to you' in the same order as listed on your log. · There were some wells on your list which were not injected into. These wells are identified as follows: · . Endicott wells 1-03/P-16, 1,65~-25~ 1-59/0-24 · EXploration well Pete's Wicked #1 · Milne Point wells E-22, E-23, F-O1, L-16, J-19, L-25, F-30, L-21, K-38, NMP #1 & #2, K-05, K-02, 1-1-07, K-25, K-37, E-17, F-21, K-30, K-34, K,21i, F-66, K-06, K-54, K-33~ F-49i, K-18 · PBU Wells E-38, 18-34, 15,42, S,29A, 15-46, B-36, 15-43, 11-38 · The reason many of these annuli were not used is because the waste materials generated froTM these wells were injected into other approved annuli. Hopefully the injection logs submitted with this letter will clarifY this. In addition, please note that our records show: · The wells listed above in italics were permitted but not used for annular disposal. · The wells listed above in BOLD were not permitted for annular disposal. Wells drilled after June 6, 1996 were required by SSD procedure to be permitted with a SUndry " Approval (10-403) form. Our records show that no Sundry Approval for Annular Disposal was filed for these wellsl Wells drilled between July 25, 1995 and june 6, 1996 were automatically approved for annular disposal with the Permit to Drill. · We also provide .you with a cumulative report from our database of records from July 25, 1995 through the present. From those records, we show the following wells not listed on your report were used for annular disposal: ,, ,Annular Disposal Letter .'. 12/14/98 Endicott wells i-23/O-15, 1-61/Q-20, 2-40/S-22 · · Exploration well Sourdough #3 - · Milne Point wells F-06, H-05, H-06, J, 13, L-24 - ~-~ · PBUwells-18-30, 18-31, 14-~,~-43, E-34, E-36, G-~A,~dS-33-~'~°~ · Individual logs ~e provided to ~ou for these ~ogs as we~l. · Finally, our records show that the B-24 outer annulus was left open (see attached correspondence) Thank you for the opportunity to provide clarity to these records.

A h ared e ioes rilling TO: Blair Wondzell FROM' Chris West DATE: October 27, 1995 SUBJECT: MPB-24 Well Suspension APl # 50-029-22642 Blair; Please find attached a copy of the Form 10-403 to temporarily suspend this well as per AOGCC 20- AAC 25.110. As discussed 'this morning we propose Setting three plugs in this well as detailed in the attached form. This will allow us to retain the wellbore for potential future sidetrack or service well use. We would like to keep the well's 9-5/8" x 7" annulus available for the injection of liquid 'wastes. There are no other well annulii on this pad for injection. The annulus for MPB-24 was approved for injection as part of the permit dated 25 January 1996. The annulus will be freeze protected before moving the rig. Thank you for your help in this matter. Please call. me if I maY be of any assistance.

In one case, there were Tioga heaters set up -in the close vicinity of the end of the divert0r lin,: and in thc oflmr instance tl~ towline cr~w wea-e working near the end of the diverter line. The ins'pemtor informed me that in both cases, the constn, ction crew had no idea of what the ali.verier line was for and no m~derstanding (ff the potential dangers aamciated with working near it. · The divcrter line is ther~ to divert gas away frmn the rig in the event that tim rig emcounte~ slndlow gas while drilling surface hole. As such, it is not acceptable to have any personnel working within 50' eft the end of the diverter line. It is totally unacceptable to have pottmtial ignition sources within 10ft of tht; end of the diverter line i.e Tioga heaters. · It is the responsibility of both the Drilling Representative and the Construction Foreman to meet daily or as required to discuss ongoing operations mid mutually identify any hazards a.~soeiatrat with same. · All rigs need to ensure that no oumide operations take place in the vicinity of ~my potential sources of hydrocarbon diseharg~ and that all sources m~ clearly i~nfified to other groups working on the pad in the vicinity of the rig or associated equipment. · It is the responsibility of construction crews and others working in the vicinity of rigs to api~ise themselves by talking to the Drilling mpresentatiw of any potential hazards in their work area and to revtew their operations aco~xrdingly. * The Drilling depamnent will take steps m provick; clear identification (ff any potential hav~rds that exist around the rig for OtherS working on the wellpad. I recommend that h~ the ca,,~e of the diverter line, an exclusion zone b~ set up with barriers around thc end of any gas diverter linc to prevent any operations or ignition ~utt:es within 10ft of the and of the lines. In addition, the line should be identified as a source of sudden gas or hydrocarbon All rigs shotfld hnmedia~ly rake action to ensure that no similar situatiolta exist on their l(x:afions smd that the potential haz;tnl.,; of simultaneous opexafions am closely scrutinized.

MEMORANDUM State of Alaska Alaska Oil and Gas Conservation Commission TO: THRU: David John,~,~ Chairma~ Blair Wondzell, P. I. Supervisor.~ FROM: Doug Amos, ~,~ ~n,,,,[_ SUBJECT: Petroleum Inspector o~ DATE: FILE NO: April 5, 1996 eirhdedd.doc Diverter System Nabors 28E BPX PBU S-42 Prudhoe Oil Pool PTD No. 96-0054 Friday, April 5, 1996: I traveled to BPX PBU S-42 well to inspect the Diverter System on Nabors Rig No. 28E. Due to work schedule conflicts I was unable to attend the initial Diverter function test on 4/4/96. When i arrived on location i found the rig and diverter system in good condition. Nabors has installed a new diverter system consisting of a MSP 21 1/4" 2000~ Annular Preventer with a single straight 16" Vent Line and 16" F/O Knife Valve. This system is a marked improvement over the 10 314" bifurcated system, in that it offers no restriction and few points for possible component erosion during divert operations. As the attached AOGCC Diverter System Inspection Form indicates the vent line is short (40' +/,-), this arrangement was unavoidable due to the location of the Flowlines directly behind the rig. I found a number of serious non compliance items during my inspection. There were no warning signs posted at or near the terminus of the 16" vent line, there were Norcon construction personnel working in front and in close proximity to the end of the vent line. In addition there were two open flame type space heaters within 20' +/- of the vent line terminus. I immediately brought these items to the attention of Nabors representative, Mike Downey and BPX representative, Charlie Dixion. Mike Downey assured me that signs would be made up and posted and Charlie Dixon contacted the Norcon construction supervisor and instructed him to suspend the flowline installation operations. I traveled back to the rig to verified that the non compliance item had indeed been corrected. While there I talked to the Norcon construction supervisor and was alarmed to find out the he had no idea that the rig could vent gas from the wellbore, through the vent line without notice. I instructed him to be sure and coordinate his construction operations with the rig supervisor in the future. Saturday, April 6, 1996: While conducting a diverter inspection at BPX MPU J- Pad and finding no warning signs on Nabors Rig 27E diverter system, ! decided to discuss this problem with BPX Shared Services Drilling Superintendent, Dick Maschell. Sunday, April 7, 1996: i met with Dick and told him about my observation. I informed him that in the future this situation would result in the shutting down of drilling operations, until the non compliance items are rectified. Dick seemed surprised and assured me that he would immediately inform the drilling supervisor's on all rigs, via E-Mail, of these serious problems. Emphasizing the need for direct communication between the construction supervisors and drilling supervisors any time there are similar simultaneous operation occurring with a Diverter System deployed. A copy of this E-Mail message is attached for reference. SUMMARY: I inspected the Diverter System on Nabors Rig 28E at BPX PBU S- 42 well. Non compliance items discovered were corrected and arrangements made to ensure future compliance.

Drilling Hazards MAR 0 1 1996 Oil & i? .... Cons. ,., Potential hydrocarbon-bearing zones expected above the Sag River include the Kuparuk, West Sak and Ugnu. A minimum of 9.8 ppg mud weight is planned for this interval. Gas cut mud has been experienced on previous S-Pad wells in this interval. Cement top is planned for 500' above the Ugnu. · Losses have been encountered drilling the Sag River, Shublik and Sadlerochit formations on other S-Pad wells. Be prepared for losses near any faults and formation interfaces between the Sag River, Shublik and Sadlerochit. · Shale sloughing, overpressure, stuck pipe and hole cleaning problems have been reported on several S-Pad wells. Mud weight, shale inhibition products, good hole cleaning and tripping practices should help minimize these problems. · Pore pressure may be as high as 9.9 ppg EMW in the Sadlerochit interval. · Faulting is prognosed for both lateral intervals and possibly in the Kingak shale interval. Lost circulation materials should be readily available. Disposal . Approval is requested for Annular Pumping on well S-42 and any other wells previously permitted on the pad (S-41 shall be primary contingency) for disposal activities by AGOCC. . The Base of the Permafrost for all wells located in the Prudhoe Bay Unit is 1,900' TVD. Aquifers in the Prudhoe Bay Unit have been exempted from Class II injection activities by the AOGCC by Aquifer Exemption Order #1 as referenced in Area Injection Order #3. . The receiving zone to which the fluids will migrate is identified as the Tertiary/Cretaceous sands formation just below _+3,071' TVD. The confining layer are the shales above the SV3 formation defined at +2,790' TVD. Additional data which demonstrates the confining layers, porosity, and permeability of the injection zone was submitted to the AOGCC on 7-24-95. . There are 39 wells on Pad/Drillsite S. There may be additional unidentified wells within a quarter mile distance from the subject well. There are no domestic or industrial water use wells located within one mile of the project area. . The drilling wastes to be disposed of during this operations can be defined as drilling mud, cement contaminated drilling mud, and drill cuttings; rig wash fluid (inclusive of rig boiler blow down, and mud and cement rinse water of associated rig equipment, completion fluids (seawater and brine), formation fluids, reserve pit fluids, and drill rig domestic waste water. (Note: if you plan to dispose of fluids OTHER than those outlined above you must list them on the request) The maximum volume to be disposed of in the annulus is 35,000 bbls. Fluid densities will range from 8.3 to 13.0 ppg. Any deviation from this program must be detailed separately. . The 9-5/8" surface casing shoe will be set at 3,071' MD (3,071' TVD) and cemented with 1,274 sacks of cement. This depth is below the base of the permafrost (1,900' TVD) and into the SV3 formation which has a long established history of annular pumping at S-Pad. The break down pressure of the SV-3 formation is estimated at 13.5 ppg equivalent mud weight. . The burst rating (80%) for the 9-5/8" surface casing is 5,496 psi. The collapse rating (80%) for the 7" intermediate/production casing is 5,616 psi. , The Maximum Allowable Surface Pressure while annular pumping is the lesser of 2,000 psi or the calculated pressure according to the following equation: MASP (psi) - (Max Breakdown ppg-8.3 ppg) X 0.052 X Surf Csg Shoe TVD MASP (psi) = 830 psi . The maximum pressure imposed at the surface casing shoe is calculated according to the following equation' Max Press @ Surf Csg Shoe (psi) = .052 x Max Breakdown ppg x Surf Csg Shoe TVD = 2,155 psi This pressure is less than the 80% burst and collapse casing pressures calculated in #7. 10.
