It appears that the deepest you can go without a variance is about 3050' and with the TOL ( 7" liner) . The schematic shows a TOW for 9 5/8"at 3166' and which is different that what you mentioned below ( 3152' md ) .... Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Rose,John G (ASRC) [mailto:John.G.Rose @bp.com] Sent: Wednesday, November 10, 2010 10:16 AM To: Schwartz, Guy L(DOA) Cc: Egbejimba, Uchenna J Subject: 3-20C - 7" Drilling Liner Lap (PTD 210-124) Guy, With the top of our J-20C 9-5/8"window at 3152' MD and as we are trying to leave enough room above the 7" liner top on this well for a future 9-5/8" sidetrack opportunity, the liner 7" lap for this well will be reduced from the normal -150'to some a lesser value not the be less than 100'which will maximize the distance from the top of this liner to the existing 13-3/8" casing shoe at 2978' MD.

Maximum anticipated surface pressure from the Sag with a full column of gas from TD to surface is 2966 psi. We will be utilizing Doyon 141's 5000 psi four preventer stack (3 rams and an annular). The BOPs will be tested to 3500 psi. The sidetrack plan for the J-20C includes the following: 1. Perform full-bore cement job setting a cement plug from the top of the WRP at 10,879' MD back . up the well to 9792' MD and perform CMIT-TxIA tQ2500 psi. 2. Make 4-1/2"tubing cut at 9600' MD. _ 3. MIRU Doyon 141. 4. Pull the 4-1/2" kill-string from the pre-rig cut at 9600' MD. 5. Set and test an EZSV in the 9-5/8" casing at 3191' MD for a whipstock departure of the well from -3174' MD (mid-window in 9-5/8"casing). 6. Drill 8-1/2" hole to TSAG at-10,550' MD.- 7.

NOTE: J-26 has not (H2S alarms from rigs,etc.) had readings>100 ppm since 1998. Faults The planned J-20C RST will not cross any mapped faults. There are two significant faults in the area. Fault#1 is a NW-SE trending, down to the SW fault with -130 ft of offset at TSHU. Fault#1 was cut by the J-09 and J-08A, both with lost circulation (see below).The JX-02, and the Q-04 (-100 ft of offset estimated from logs) also penetrated Fault#1, but neither apparently had losses. Fault#1 cuts upsection at least has high as the THRZ. Fault#2 is an E-W trending fault with 30-50 ft of down to the N offset at TSHU. Fault#3 was cut by the H-20 and probably by the Q-02A, neither of which noted losses. After a high kickoff, the well is planned to stay above and north of the fault plane of Fault#1. The well then curves around to the West, staying parallel to and north of Fault#2. Dips should be nearly flat in the production section except near the BHL. From -13,450 MD to TD, dips may be up to 11/20 to the East. Drilling Waste Disposal • There is no annular injection in this well. • Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. • Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection.

Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three-ram drilling BOP stack.

Prior to picking up or running any equipment or tools in the hole, a PJSM and discussion is required to identify and note any equipment which will be run through the BOPE and is non- shearable. A risk assessment shall be performed for any equipment which is deemed non-shearable. The risk assessment must address the following: 1. Can variable bore rams seal against the equipment? 2. Can an annular preventer seal against the equipment? 3. Is a cross-over readily available to make-up into equipment? 4. Is a single joint or full stand of DP readily available to lower equipment below the BOPE stack? 5. How the equipment can be intentionally dropped down hole. 6. Are weights of equipment known so that hydraulic jacking force of wellbore pressure can be calculated. 7. Accurate and up to date shearing capabilities for the current shear rams installed is available. 8. Has each crew member been versed on individual roles and responsibilities? If there is a well control event happens with non-shearable equipment across the BOPE shear rams, the following procedure should be followed: 1. Based on the risk assessment above, gain control of the well by either: a. Closing the appropriate preventer(pipe ram, VBR, or annular) or b. Placing a sealable piece of equipment across the BOPE and closing the appropriate preventer or c. Dropping equipment and closing the Blind or Blind/Shear rams. 2. If well conditions permit, contact appropriate personnel. If not, proceed with well kill operations. This may include placing shearable equipment (i.e. drillpipe) across the shear rams by stripping in/out of the hole.

ASRC well test J-20C PTD Page 11 8/26/2010 J-20C Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. Intermediate Hole - Given a max cretaceous injection pressure of 9.6 ppg, this wellplan dictates the use of a 9.8 ppg LSND mud from the KOP in the SV sands to the top of the HRZ. From that point to the 8-1/2"TD in the top of the Sag, a 10.4 ppg mud will be used as dictated by the Kingak polar plot. B. Production Hole - The Ivishak in this area is expected to be under-pressured at 6.9 ppg EMW. This interval will be drilled with a reservoir drill-in fluid (FloPro SF) with a fluid density of 8.5-8.8 ppg. II. Lost Circulation/Breathing A. Intermediate Hole - While no major lost circulation is expected in this interval of the well, breathing and/or lost circulation is a possibility due to the shallow KOP on this well which exposes all formations from the SV4 to the TSAG to drilling ECD's associated with the planned 10.4 ppg mud density. B. Production Hole - The planned location is in an area of "Moderate" (i.e. average) risk of lost circulation according to the WURD study. However, the area just to the South is considered "High" risk of lost circulation. The nearest lost significant lost circulation incident to the planned well was -1000 ft North and West in the Q-03A which lost 250 bbls into Zone 2, not associated with a mapped fault. About 3500 ft NW the J-09 and J-09A lost 1200 bbls and 240 bbls respectively into Fault #1. Thus Fault #1 is known to have a significant history of lost circulation. However, it should be noted that the JX-02 and Q-4 also crossed Fault #1, but had no lost circulation problems. Although the J-20C will be near (but not cross) a fault with a known history of lost circulation, it is considered to have low risk of lost circulation. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 58.6 bbls, and for the production section is infinite. The FIT/LOT will prove up adequate formation strength for expected ECD's. B. Integrity Testing Test Point Test Death 110 EMW(lb/gal) 9-%" window 20-ft minimum from the 9-%" window FIT/LOT 11.1 minimum 7" shoe 20-ft minimum from the 7" shoe FIT/LOT 8.9 minimum IV. Hydrogen Sulfide J-Pad is not considered an H2S site.The highest recorded H2S on the pad was 110 ppm on J-26. V. Faults The J-20C wellpath is not expected to intersect any mapped faults. VI. Anti-Collision Issues There are no anti-collision issues as all off-set wells pass Major Risk analysis.

Since the open lateral (J-20B) is in the same pool as the target reservoir for the rig sidetrack there is no issue with crossflow of fluids between zones or pools. Additionally, even though the cement plug is almost 1700' and away from the open pert zone in J-20B the well will be properly contained from migrating to other strata or surface by the cement plug and confining 4.5" casing liner that was fully cemented. The commission has discretion regarding alternate methods of P &A wells and your cement plug above the fish would meet this requirement provided it passes a pressure test. Call me if there needs to be any further clarification or discussion. Regards, Guy Schwartz Senior Petroleum Engineer AOGCC 793-1226 (office) 444-3433 (cell) From: Rose, John G (ASRC) [mailto:John.G.Rose @bp.com] Sent: Friday, August 06, 2010 12:17 PM To: Schwartz, Guy L (DOA) Cc: Egbejimba, Uchenna J Subject: FW: J-20B P&A Guy, As we consider the issues associated with the sidetracking of the J-20B well to a new Ivishak Zone 2 target as the J-20C well, AOGCC approval of our P&A plan for the current J-20B well is a very critical issue which will have a significant impact on our moving forward with a sidetracking plans for this well. Therefore, given the following brief description of the well in its current condition and the proposed P&A, please provide some feedback as whether this plan meets AOGCC requirements: 1. J-20B is currently shut-in/suspended post the 4/09 RWO where"junk"was left in the well above a wireline retrievable plug (10,879' MD). 2. During the 4/09 RWO (which was designed to install a scab liner to resolve a PC/production packer leak), after cementing the scab liner and while trying to clean-out above 4.5"WRP, 3 fishing assemblies were broke off inside the 4-1/2"tubing and a significant effort was made to recover the junk and salvage the J-20B well. However, after the recovery of 2 of the fish, the current well was suspended with a partial boot basket and a 5' mill remaining in the well as un-recovered junk above the WRP. 3. J-20B is now being considered for a rotary sidetrack which will involve sidetracking the well from above the existing 7" scab liner out of the 9-5/8" casing at-3170' MD targeting new Ivishak Zone 2 reserves. 4. The proposed P&A for this well will be to pump cement down the existing 4-1/2" kill string placing a cement plug from the top of the WRP at 10,879' MD back up the well to -9792' MD on both sides of the kill string. Given our un-successful attempts to recover the existing junk in this well, the approval of this P&A plan will allow us to move forward with the our planning efforts for J-20C RST with a clear understanding of our P&A 9/7/2010 Page 2 of 2 requirements. I have attached a document to this e-mail which provides additional details of this well's history and RST plans as well as 2 well schematics detailing the well in its current condition as well as its planned post P&A condition, therefore, please advise as to your agreement/approval of this planned P&A. Thanks -jr Note: This planned P&A is based upon the AOGCC regulations as referenced below: http://www.legis.state.ak.us/basis/folioproxy.asp?url=http:/iwwwjnu01.legis.state.ak.us/cgi- bin/folioisa.dll/aac/query= JUMP:%2720+aac+252E112%27]/doc/{©1}?firsthit (c) Plugging of cased portions of a wellbore must be performed in a manner that ensures that all hydrocarbons and freshwater are confined to their respective indigenous strata and are prevented from migrating into other strata or to the surface. The minimum requirements for plugging cased portions of a wellbore are as follows: (1) perforated intervals must be plugged by one of the following methods: (A) by the displacement method, a cement plug placed from 100 feet below the base to 50 feet above the base of the perforated interval and from 50 feet below the top to 100 feet above the top of the perforated interval; (B) by the displacement method, a cement plug placed from the well's total depth to 100 feet above the top of the perforated interval; (C) by the displacement method, a cement plug placed from the well's plugged-back total depth to 100 feet above the top of the perforated interval, if all hydrocarbon-bearing, abnormally geo-pressured, and freshwater strata below are isolated; however, the commission will approve plugging from the top of fill or the top of junk instead of from the plugged-back total depth, if the commission determines that the objectives of this subsection will be met; John G.Rose BPX-Staff Engineer Office 907/564-5271 Cell 907/748-5223 FAX 907/564-4040 Home 907/243-8813 9/7/2010 Alaska Department of Natural Resources Land Administration System Page 1 of, NAlaska Mapper Land Records/Status Plats Recorder's Search State Cabins Natural Resources r---- Alaska DNR Case Summary File Type: ADL File Number: 28281 Printable Case File Summary See Township,Range, Section and Acreage?
