Based on the IPROF a WRP will be set to isolate the 42P perfs • and focus injection on the 45P if necessary. Well History B -13B is an injector that was D &C in summer 2010. The well was initially completed in the 42P sand with perforations from 10302 - 10318' md. The well was swapped to MI injection in February 2011 and has injected 3.67 Bscf of MI to date. The MI slug was meant to mobilize • various oil lenses logged in B -13B to the offset producers B -01 and B -25. Page 1 of 7 B 13B • • B -01 and B -25 are completed in upper Z4 with perforations in the 46P, 45P and 44P. Since these wells are completed higher in section than B -13B, there is little value to water injection in the current 42P perforations. B -13B has a poor primary liner cement job which is documented on the SCMT logged 7/2/2010 and clarified by a Borax log run 7/18/2010. There is poor cement in the well from 10174-10190' and and 10254' and to TD. A channel is shown on the Borax log from 10226- 10340'md. Eline shot perfs in the 45P on 8/07/2012 after a round of MI was injected into the bottom perforation in the 42P in hope to mobilize some stranded oil lens when migrating up. Based on the IPROF if the majority of the water is entering the 42P perforations, then a WSO • plug will be set to improve the conformance and maintain water injection above the 44N shale.

The report details the running of the tubing and the successful testing of the tubing and IA on 6/20. I don't find any mention of "dropping the ball and rod" and actually setting the packer. I assume that was done some time prior to 1830. Can you help me with this? Thanks in advance.

All of the zone 4 Ivishak is open to injection through the limited perf interval that we have shot. The Ivishak zone 3 and the Sag river formations are isolated by competent cement. Since zone 3 is isolated, we decided not to remediate the cement job and have put the well on injection into zone 4. We were all stumped as to why the cement was incompetent. We also agreed that the job was pumped to plan and should have been perfect. At this time we will not remediate the cement unless we break down the cement above zone 3 and start seeing injection slumping int he formation.

There are some comments in the post rig work summary regarding channeling /communication as determined by WFL above and below the perforations. Sort of surprising since the cementing operation appears to have gone well and the pipe was reciprocated. Are remedial operations planned? Thanks in advance.

The well, B -13B, was sidetracked out of an existing injector and penetrates the Sag and Ivishak zone 4 and zone 3. The USIT cement bond log on the 7" liner was logged on 6/18/10 and showed good cement quality from 9213' MD to just above the shoe at 9996' MD. A SCMT was logged on the 4 -1/2" production liner on 7/2/10 and showed good cement below the liner hanger at 9890' and to above the sag river at 10060' MD. We added a single set of perforations in the 42P interval at 10302'- 10318' MD. We are planning to put this well on injection at 1000 bwpd to let it warm up for an AOGCC witnessed integrity test. Please let me know if you would like to see the logs or if you have any issues with the plan to move forward with injection. I have attached a wellbore schematic for your information. «B- 13B.pdf» Thank You, Laurie Laurie Rose Derrick 8/16/2010 t MECHANICAL INTEGRITY REPORT FuD DA.T.E . .(� - a t oPER & FIELD RIG RELEASE: •1 1s1 WELL NUMBER W E L L DATA T D : 1�`t'Zv3�D S \off TVD.; ?ETD: \oN 'ACc 50 l TVD Casing: ''t Shoe : 1 7 Q)051 TVD ; DV: �1 i TVD 'Liner : �(� Shoe: kpy1/4t .rJ cstc3 \, T VD ; TOP : Cat ¶S(3 TvD Tubing: \ Packer Ole E' A TVD; Set at Hole Size Sk( and ‘,j ; Perfs t0 ."3 to . 03•c ' • • LS CHANT CI-1 INTEGRI'T'Y - ?ART # 1 Annulus Press Iest: IP a93) = 15 mirda4(Q6 ; 30 mina 6v Comments: ( v l v.; 1v,. ca MECRANIC?.L INTEGRITY - PART ?2, Cement Vol MS r Amt.

It also appears to be a good idea in respect to having another full annulus as a barrier to the old 9 5/8" production casing. I certainly don't see any downside to a 7" longstring. I will make the updates in our well file. Plan change regarding 7" longstring for B -13B is approved. Guy Schwartz Senior Petroleum Engineer AOGCC 793 -1226 (office) 444 -3433 (cell) From: Medvedeva, Maria [mailto:Maria.Medvedeva ©BP.com] Sent: Thursday, May 20, 2010 11:57 PM To: Schwartz, Guy L (DOA) Cc: Tirpack, Robert B; Egbejimba, Uchenna J Subject: B -13B changes to drilling permit «B -13B Proposed.pdf» apologize for contacting you this late, but I would like to discuss /approve a change to the permit to drill on well B- 13Bi, permit #210 -039. To refresh your memory, B -13Bi well is scheduled to be drilled by Doyon Rig 14. They are moving on location now, scheduled to arrive on B pad 05/21 early morning. The sidetrack plan for this injector includes the following: pre -rig operations completed (pumped cement across the perforations and cut the 5 -1/2" tubing at approximately 318 MD). Inc whipstock exit from tr,e 5 - 5/8" casing is estumateo at 2870' MD and will be milled using an 8 - 1/2" stiff mill assembly during rig operations. The 8 - 1/2" hole will be drilled to the top of the Sag River where a_7" casing will be run and cemented with a 1,000' tail of 15 8 ppg class G cement. The production hole will be drilled with a 6 -1/8" BHA. The well will then run through the Ivishak Zone 4 formation to TD at 10,476' MD. At this time we would run a USIT log across the 7' shoe to verify cement quality. inc liner wiii be a 4 - 1/2" u80 liner and the tubing will be 4-1/2" L80 TCII, tied into the top of the production liner. The solid 4 -1/2" production liner will be run and cemented in place. Post -rig operations will include perforating -100' of liner. An SCMT log will be run across the reservoir section during the perforating operations. The change to current operations is to run the 7" to surface making it a longstring, compared to previous plan to run it as a liner witn a liner top packer and hanger. This change of scope is beneficial for the 7" casing cement job betty r quality and less risk of contamination. Please review and consider this change, for questions contact myself or Rob Tirpack /John Egbejimba from the BP office. 5/21/2010 B - changes to drilling per.

The sidetrack plan for the B -13B includes the following: during pre -rig operations laying cement across the perforations and cutting the 5 -1/2" tubing at approximately 3170' MD. The whipstock exit from the 9 -5/8" casing is estimated at 2870' MD and will be milled using an 8 -1/2" milling assembly during rig operations. The 8 -1/2" hole will be drilled to the top of the Sag River where a 7" drilling liner will be run and cemented with a 1,000' tail of 15.8 ppg class G cement. The production hole will be drilled with a 6-1/8" BHA. The well will then run through the Ivishak Zone 4 formation to TD at 10,470' MD. The liner will be a 4 -1/2" L80 IBT -M liner and the tubing will be 4 -1/2" L80 TCII, tied into the top of the production liner. The solid 4 -1/2" production liner will be run and cemented in place. Post -rig operations will include perforating -100' of liner. An SCMT log will be run across the reservoir section during the perforating operations.

(H2S alarms from rigs, etc.) Faults There are no fault crossings anticipated in the current well plan. However, there has been numerous lost circulation events in the parent well bores and in other wells in the area, most of which can be linked to fault crossings and proximity. This well plan has been designed to mitigate these risks and to be as far from the major faults in the area as possible. There are four larger faults in the area as listed below (A -D).

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. Disposal • 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. Haul all Class I waste to Pad 3 for disposal. B -13B Permit to Drill Application Page 6 • Drillinn Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. Maximum reservoir pressures anticipated based on offset well pressures. 4000 si accordance with the RP for Prudhoe injection well casing tests. Interval PSI (EMW) MD (ft) TVDss (ft) Ivishak Z4 3380 (7.2) 10470 9042 B. Be aware of possible UGNU overpressure. Over - pressure from the produced water injection in the UGNU sands is expected. Most probable area is about 4600'ss. Broaching also occurred on the B -pad from the injection fluid. C. Be prepared for lost returns on B -Pad, have LCM pills premixed and ready. B -pad is a high lost circulation region, highly faulted area. Severe lost returns on 7 of 8 CTU sidetracks, between years of 1997 - 2001. On the most recent sidetracks: B -05B, B -30A (CTU), B -23A, B -33A and B -29A experienced serious lost returns. B -12A drilled to TD without incident but had other troubles logging. D. Tight hole, swabbing, and bridges, requiring normal working and /or washing and reaming occurred on most wells throughout B Pad. Most of these incidents were handled in routine operations II. Lost Circulation /Breathing A. There are no fault crossings anticipated in the current well plan. However, there has been numerous lost circulation events in the parent well bores and in other wells in the area, most of which can be linked to fault crossings and proximity. a. This well plan has been designed to mitigate these risks and to be as far from the major faults in the area as possible. There are four larger faults in the area (A -D). Fault A is just south of the target polygon, Fault B is to the west, Fault C to the north and Fault D to the Northeast. b. B -13 (1978) experienced +/- 3200 bbls loss at 10,537' (8755' tvd) and 300 bbls loss at 11,001' (9091'tvd) in the production hole interval in the Ivishak zone. i. Severe loss ( >$150,000) and a Moderate loss ($15,000- 150,000) c. B -13Ai (1999 CTU) experienced 3938 bbls at 11,875' & other depths in Ivishak zone 4. The wellbore was treated with Form -A -Set and cement. i. Severe loss >$150,000 B. 7 of 8 1999 to 2001 CTU sidetracks had lost returns, up to 7700 bbls of B -29A, +/ -8000 bbls after milling out the window in production hole on B -23A, 7980 bbls after drilling out the shoe on B -33A. Also, B -05A (2001) had serious lost returns and experienced breathing. a. Lessons Learned: Minimize mud weight (drill w/ viscosified seawater if necessary (8.4 ppg)), have LCM pills premixed and ready. III. Kick Tolerance /Integrity Testing A. With the planned 9.3 ppg mud weight, the kick tolerance for the intermediate section is 46.3 bbls. With the planned 8.7 ppg mud weight, the kick tolerance for the production section is infinite. The FIT /LOT will prove up adequate formation strength for expected ECD's. B.

The B -33 has been plugged and abandoned and the current active wellbore is B -33A. B -33A is a Sag /4B zone producer. B -13B will target Ivishak Z4. B -24 is a LTSI with a plug in the tail pipe. Do you need the exact distances from bottom hole location to bottom hole location of B -13B to the near by wells? We would test the casing and the liner to 3,500 psi for 30 minutes after setting the liner top packer and POOH (after step 31). You didn't miss anything - this will be the new step #32 (I had missed this myself). Next we would RU and run the 4 -1/2" completion tubing (step #33). Thanks for the patience!

I don't think any of these would be in -zone with -in the quarter mile circle though except for B -24.

Closest well to the BHL of B -13B is a long term shut in producer B -24, 640'. A tubing tail plug has been set in B -24. I am attaching a locator map that the geologist sent to me. Please let me know what further information /material you may need.

Maria Medveddeva:a BP.com From: Schwartz, Guy L (DOA) [ mailto:guy.schwartz @alaska.gov] Sent: Thursday, April 08, 2010 10:39 AM To: Medvedeva, Maria Subject: B -13B Sidetrack (PTD 210 -039) Maria, I am reviewing the PTD for this well. The BHL doesn't have a AOR included in the packet. A % mile plot is needed to see what other wells are in the area that may be affected by the new BHL. Also, you list test pressures for the BOP and casing at 3500 psi. I thought BP policy was 4000 psi for injection or WAG wells.
