My preferences can't interfere with or dictate changes to work schedules that have been agreed to or are conditional for permits. Permission for continuation of this work or final site clearance (A.O.G.C.C.) until next summer is not a call I can make from my position. I have Cc'd my supervisor, Jim Regg, on this e-mail.

Given our phone conversation two days ago in which you indicated a preference to visit the site after the remediation is completed, I'm assuming that it will be okay for us to not complete the final site clearance visit until next summer after remediation work is completed. Please get back with me to confirm that this acceptable.

Put River 33 -12 -13 to witness a pressure test of surface plug & thru tree surface cement tag (Sundry 312 -036) Pump was R/U on the tree when I arrived on location. Several attempts to PT were made before the successful pressure test was accepted by BPXA (2500 psi test that lost 243 psi in 15 minutes). A 50 -ft strapping tape was lowered thru tree to verify TOC without success. String with weight attached was lowered to 58' to find TOC. BPX will evaluate PT & TOC to determine plan forward. Summary: I witnessed pressure test on surface cement plug that meets BPXA criteria for passing pressure test. TOC was then found @ 58' from top of tree.

Chart the 9 5/8" casing pressure test (2500 psi ) before you begin to lay in the cement plug from the bottom at 9200' md. If it doesn't hold pressure you will have to break up the cement plugs into two parts and get a passing PT after the first plug to 6000' as per the original procedure. Call me if you have any questions. Guy Schwartz Senior Petroleum Engineer AOGCC 793 -1226 (office) �� 444 -3433 (cell) MAY 2 1 From Worthington, Aras 3 [ mailto:Aras.Worthington ©bp.com] Sent: Tuesday, April 24, 2012 11:22 AM To: Schwartz, Guy L (DOA) Subject: Put River 33 -12 -13 P&A Sundry #312 -036 Guy, I'd like to propose a slight change of plans for the P &A on Put River. Just to update where we are on the well: The Workover rig finished cutting and pulling the 10 -3/4" casing and ran new 9 -5/8" casing and cemented that string to surface (13 -3/8" x 9 -5/8" annulus cemented to surface from —2500' MD). As well the workover rig has completed cementing of the curtain string (originally this step was in the post -rig step #5 but we went ahead and did it on -rig). Currently the workover rig is drilling out the cement above the 9 -5/8" CIBP @ 2523' MD and then they will drill out the CIBP, CO to TD and Swap the well to seawater then RDMO. Point forward we have all annuli in the well cemented so all that is left is to cement the 9 -5/8" casing. We propose to do this by laying a solid cement plug from TD to surface (provided the PT of the wellbore will hold a full column of cement. If not, we will have to break the plug up as originally proposed in the Sundry). We will use Class G for depths below 2000' MD and Arcticset I or the permafrost blend of Class G for the depths above 2000' MD. Obviously if we do the job this way there won't be the opportunity for the AOGCC to witness and tag and PT of the plug @ 6000' MD but AOGCC could witness tag and PT of the continuous plug at surface. Please advise if this is an acceptable change of course. Aras Worthington Wells Intervention Engineer BP Alaska Inc.

(It appears though that the 9 5/8" port collar ( diverter?) you are proposing to circulate through will be at 2200' md.)

Reference Steps #3 and #4 in the post -rig procedure. These steps would be performed on -rig with the cement circulated through the diverter installed in the new 9 -5/8" casing @ -2500' MD.

Please let me know if you have any further questions. • Reserve pit waste excavated and pit backfilled. Approximately 5,432 loose cubic yards (LCYs) of Class II, Resource Conservation and Recovery Act, exploration- and - production- exempt drilling waste and petroleum hydrocarbon- impacted material were excavated from the reserve pit and flare pit areas and hauled to the grind and inject facility at Drill Site 4 in the Eastern Operating Area of the Prudhoe Bay Unit for down -hole disposal in a Class 1 injection well. The reserve pit and flare pit were backfilled with gravel, which was then capped with approximately 2,380 LCYs of organic - rich overburden • Gravel pad removed to tundra grade. Approximately 10,400 LCYs of impacted gravel and tundra were excavated from the gravel drill -pad area, as well as tundra areas adjacent to the northern margin of the pad. This material was hauled to the East Dock Landfarm (EDLF) for treatment and eventual re -use. Approximately 16,000 LCYs of clean gravel were excavated from the gravel drill - pad, as well as the west pit and reserve pit containment berms. An estimated 1,800 LCYs of this clean gravel was used on -site as backfill. The remaining gravel was staged at the Dead Arm Pit for eventual reuse. • Sample results document cleanup levels achieved. Confirmation sample results for the reserve pit, flare pit, and impacted areas of the gravel pad document that target cleanup levels were achieved. Backfilled excavations within the reserve pit, flare pit, and gravel drill pad areas, as well as areas adjacent to the gravel drill -pad, are currently ready for re- vegetation. A site - specific rehabilitation plan is being developed separately to address re- vegetation at this site.

The ice road season is quickly coming to an end for this winter. With collapsed casing the options to access the lower part of the wellbore become complex and will likely require a rotary rig. The well may remain suspended with the existing barriers already approved in the earlier sundry (# 310 -346 ) "Suspended Status Renewal ". You are granted a 2 yr extension to the suspended status of the PR33 -12 -13 (until 12/31/13) with the understanding that operations to P & A will resume next winter ice season.

This well was drilled from a gravel pad approximately 1 mile west of T pad. There is currently no gravel road to access this pad and requires an ice road to gain access. A suspended well inspection was completed on 9/22/10 and the results were submitted with a report of Sundry Well Operations (form 10 -404) on 9/25/10. There was no discoloration and no sheens on the pad, pits, or in nearby water. This well was drilled to a depth of 9,237' MD, but was never perforated. The well is mechanically sound based on cemented casing. A bridge plug was set at 2,523' MD to secure the well before the final suspension on 12/20/69. BPXA received a Sundry (311 -091) to P&A this well during the ice road season of 2010/2011. However, collapsed casing was encountered and the proposed plan to complete the P &A will not be possible. There were 3 sections of collapsed casing found above the bridge plug. The top 2 collapsed sections were at 841' - 853' and 1,066' - 1,078' in the 10 -3/4" casing. The last section of collapsed casing was at 2,489' - 2,495' in the 9 -5/8" casing. The status of the 13 -3/8" casing is unclear at this time. 4/19/2011 Request for extension of suspended.us of Put River 33 -12 -13 (PTD 169 -104 Page 2 of 2 BPXA received a renewal of suspension status until 12/31/2011 via Sundry 310 -436. Due to the collapsed casing a new scope of work must be generated to complete this P &A. We request an extension of suspended status for Put River 33 -12 -13 of up to 3 years, until 12/31/14 to complete the Put River 33 -12 -13 P &A. A variance to the provisions of 20 AAC 25.110(c)(2) is requested under 20 AAC 25.112 (i) to allow the well to remain suspended in its current condition. If this is acceptable, BP will withdraw Sundry 311 -091. Attached is a schematic of the current completion for Put River 33- 12 -13. Please contact me with any questions.

To ./ gain access to the bottom of the well, a hole must be drilled through a 9 -5/8" CIBP. A service coiled tubing unit will be used to mill a pilot hole through the CIBP. This well was not perforated and two cement plugs will be placed downhole to abandon this well. The first cement plug will be placed from 9,237' MD (PBTD) to 7,300' MD in the 9 -5/8" casing. The / second cement plug will be placed across the surface shoe from 3,700' MD to surface in both the annulus and casing. In addition to the cement plugs, the diesel will be circulated out of the 20" x 13 -3/8" annulus. A 16" curtain string was run in this annulus to a depth of 2,095' MD. After circulating out the diesel, cement will be circulated to surface in the 20" x 13 -3/8" annulus. Once the cement plugs are placed, the site will be excavated and the wellhead will be cut off a minimum - of 4' below tundra level. A marker plate will be placed on top of the cut -off casing stating the Operators name, well name, PTD, and API number. We expect to start the abandonment on March 31, 2011.

The well is located on single well inactive gravel pad not accessible from the PBU road system, about 1 mile west of PBU T pad. BP Exploration (Alaska), Inc. (BPXA) completed a suspended well inspection of PBU TR PR 33 -12 -13 on 09/22/10. The results of that inspection were submitted with a Report of Sundry Well Operations (form 10 -404) on 9/25/10. PBU TR PR 33 -12 -13 is secured with cemented casing and a bridge plug. The well was not perforated. The well is mechanically sound based on cemented casing. The well will not allow the migration of fluids, will not damage freshwater or producing or potentially producing formations, will not impair the recovery of oil or gas, and is secure, safe, and not a threat to public health. The strata through which the well was drilled is neither abnormally geo- pressured or depleted. The well is planned to be plugged and abandoned in 2011: There are no facilities near this well and the Ivishak in this area has been developed from F, R and T pads. Condition of the Wellhead and Surface Location PBU TR PR 33 -12 -13 is located on an inactive pad with clean gravel. The pit and surrounding area are in good condition with some remaining debris. There is no discoloration and no sheens on the pad, pits, or in nearby water. During the inspection, it was noted that the well sign is damaged. The current well pressure readings are unavailable due to the current configuration of the tree. Request BPXA requests approval for renewal of the existing suspension status for PBU TR PR 33 -12- 13 through 12/31/2011 to allow time for the planned P &A to be completed. A variance to the provisions of 20 AAC 25.110 (c) (2) is also requested under 20 AAC 25.112 (i) to allow the well to be remain suspended in its current condition. All hydrocarbon intervals are isolated and there are no underground sources of fresh water in this area. MLB 12/17/10 • • • ' COMPLETION DIAGRAM WELL No. BP 41- 33 -12 -13 RTKB 48. 38, FT.

Yours Sincerely, Steve Herren Drilling Manager Bill Bredar Patrick Collins Jim Farnsworth Mike Miller Bruce Policky Scott Sigurdson Marian Sloan RECEIVED ' OCT 1 4 1994 Alaska 0il & Gas Cons. Commission Anchor~ Suspended Well~, Request to retain suspension status The following wells are listed as suspended by the AOGCC under 20 AAC 25.110. These wells are requested to remain suspended for the reason(s) as indicated. Site inspections should be conducted as soon as possible. MPA-01; 029-20376-00 79-/¢04 Potential recompletion in the Kuparuk C and/or B sand as a water injector. Decision hinges on 1994/95 development drilling results (E-13)in this area. MPB-02; 029-20662-00 81-/¢/142 This well is scheduled for initial completion in the Schrader Bluff late this year or early next year. MPA-03; 029-20891-00 83-~001 Future utility as a Schrader Bluff producer with producing utility when surface infrastructure is installed on A pad. MPN-01 B; 029-21053-02 84-0013 N-01 B is a usable well in the Schrader Bluff, with producing utility when surface infrastructure is installed on N pad. The well should be retained in a suspended status until that time. MPC-16; 029-21364-00 85-0110 C-16 has recompletion potential in the Kuparuk "C" sand and/or the Schrader Bluff horizons. Although additional evaluation must be performed to quantify reserves and production potential, C-16 is believed to be a viable workover and/or sidetrack candidate. NWM# 1; 029-22231-00 91-0145 Northwest Milne #1 should remain suspended until the Northwest Milne Point development is better defined. The wellbore is strategically located on a gravel island and may possess utility in either production or injection operations. DNR recently certified this well as capable of production. No Point #1; 029-22450-00 94-0027 No Point #1 will be utilized in the upcoming F- Pad development. Expectations are to complete the Kuparuk "A" zone and commence production 4Q95. Niakuk #4, 029-21217-00 84-0200 Niakuk #4 is requested to remain suspended until the viability of the well for monitoring is defined. Niakuk #5, 029-21290-00 85-0O27 Niakuk #5 should remain suspended for observation purposes at this time. Sag Delta #33-12-16, 029-20176-00 75-0058 Area being drained by 1994 Alapah well NK-26 (HAW). Potential use as a monitor well for this new reservoir Would have to truck oil across winter ice road if resume production Produced 186 MBO in 1985 2 month production test. Sag Delta #5, 029-20527-00 80-0129 Area being drained by L5-26 (high gas well), L5-28, and L5-36 from south to west. Well tests indicated fairly tight, but productive rock; perhaps inadequate stimulation? Costs prohibitive for eventual tie-in to L5 (? via Heald Point). Potential for gas cap monitor well Sag Delta 31-11-16, 029-2001 69-0014 1-00 Area being drained by L4-36, 80 Acre offset to NW. Potential for service well (water injection?) Well is capable of production, but most Lisburne in water leg and costs likely prohibitive for tie-in to L4. Sag Delta #2A, 029-20234-01 77-0069 South of Sag Delta #1, in water leg of Alapah oil accumulation in NK-26 well. Remote potential for pressure monitoring of Alapah offtake and the effect on the Alapah aquifer; though, costs would likely be prohibitive. Sag Delta #8, 029-20519-00 80-0121 Z-32A, 029-21924-01 93-011 3 S-10A, 029-20765-01 91-0123 Sag Delta #8 should remain suspended until the development plan for the area is better defined. This well may possess utility for production or as an observation well. Z-32 was shut in due to high water production in 1992. In 1993 it was sidetracked to a new location. The oil column at the new location was less than prognosed and was not considered economic and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. S-10 was sidetracked in 1992. Drilling difficulties were encountered while drilling through a fault in the Kingiak and the well was suspended. There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. The West Sak formation, a non unitized formation in the PBU license area, is reachable from this wellbore. Work in ongoing on a facility sharing agreement. In the case that a satisfactory agreement is reached, this wellbore could be used to access oil in this formation. Y-22A, 029-21558-01 88-0115 Y-22 was sidetracked in 1988. The sidetrack was suspended due to drilling difficulties. There is oil in the region that can be reached as a new sidetrack from this well. A location has not been worked on but we wish to retain this wellbore for a future sidetrack. U-01, 029-22244-00 92-0011 There is oil in the area that can be reached as a new sidetrack from this well. A specific location has not yet been identified, but we wish to retain this wellbore for a future sidetrack. PR 33-12-13, 029-20047-00 69-0104 The well penetrates The West Sak and Ugnu formations in the aquifer. Work in ongoing on a facility sharing agreement with subsequent appraisal of the formations. This well could be used to test the aquifer properties. These wells are listed as suspended, action items are detailed. Ak Island Cf1,289-20018-00 81-0119 Alaska Island #1 was abandoned in 1988. The completion notice has been refiled with AOGCC on 9/15/94. The site is ready for inspection (priority 1 ). Niakuk CflA, 029-20156-01 76-0028 Niakuk #lA was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1 ). Niakuk Cf2A, 029-20180-01 76-0079 Niakuk #2A was abandoned in 1991. A sundry application requesting status change was filed with AOGCC 9/20/94. A completion notice will follow when the sundry application is approved. The site is ready for inspection (priority 1). PBU H-01, 029-20099-00 71-0015 The well was drilled in 1971 and hit a down thrown fault block with only 20ft of oil bearing Ivishak. This was not economic at the time. It was left suspended without tubing. Recent success in fraccing the Sag formation indicated that it might be an economic well. A rig workover was completed in April 1994 and the well was put on production 9/94. It is not necessary to inspect this site. Kemik Unit #1,223-20006-00 70-0060 Kemik Unit Cf1 is scheduled to be abandoned in the near future. Abandonment planning is now in progress. Site inspection will not be necessary at this time most likely should be scheduled for Spring of 1995. P2-59, 029-22096-00 90-0140 Arco Alaska Inc. is the operator of this well, they will be addressing the question of suspension. Sag Delta #3, 029-20233-00 79-0080 Well plugged and abandoned March, 1991. Well completion notice will be refiled with the Commission. Sag Delta #4, 029-20245-00 77-0015 Well plugged and abandoned March, 1991. Well completion notice will be refiled with the Commission. The following wells are not under BP Exploration ownership.

Section ll0(a) of the regulations states theCommission will, in its discretion, approve the suspension of a well if the well is capable of producing hydrocarbons in paying quantities or is reasonably demonstrated to have future value as a service well. SeCtion 105(e) states that "[e]ach well to be abandoned or suspended must be plugged...to prevent the movement of fluid either into or between freshwater and hydrocarbon sources and to ..prevent all other fluid migration within the well bore." In compliance with Section 170(a) of the regulations, "It]he location of an abandoned well onshore or upon a historically stable island must be clearedwithin one year following well abandonment .... " Section 170(b) provides the means for an extension of time if a valid reason exists, and the well bore is properly plugged. ~-- Mr. R. S. Allan -~-~' July 31 1986 · :"..? Page 2 We are,. therefore, requesting you to submit Form 10-403, Application for Sundry Approval, with a program which will bring the status of these wells into compliance with the new regulations and provide a schedule for this summer when our field inspectors can accompany your representatives to the well sites for location clearance inspection.

As the attached pictures show, BP 22-33-11-13 and 41-33-12-13 well locations have miscellaneous debris that will have to be removed before clean-up approval can be granted. In summary, I conducted the clean-up inspection on Sohio's BP 22-33-11-13 and 41-33-12-13 wells.
