History of 03-15B: Parent well 03-15B was a Sag producer completed in 2015 that had a sump into the Ivishak zone 4B. When it was drilled, the parent encountered 60' TVD of logged oil (Resistivity >8 Ohms), the well was then completed with sliding sleeves and swell packers. Due to the completion type we are unable to isolate the water from the oil . production and the well is uncompetitive in its current configuration. The best use of the wellbore is a CTD sidetrack to re-access the oil column and provide isolation from the water. Proposed plan for 03-15C: The 03-15C will be a short coil slant well near the parent that will be drilled through the logged oil and will TD in the Victor Package (Z4A/Z3/Z2C). It will TD in the victor package to provide an offtake point in in the area for the current MIST injectors 03-36Ai and 03-07Ai, and access the Victor oil pad that has been mapped and sits under the thick, continuous 42N shale that is in the area. The sidetrack will be drilled with the Nabors CDR2 rig on or around January 15th 2018. A 4-1/2"whipstock will be set pre-rig inside the production liner. The rig will move in, kill the well (if needed) and mill a 3.80"window, -10' long. The well kicks- off in the Shublik and will be drilled down into Zone 2C. The proposed sidetrack is a -550' horizontal Ivishak producer to be completed with a 3-1/4" 13Cr solid liner, cemented in place and selectively perforated (post-rig). This Sundry covers plugging the existing 03-15B production via the whipstock set pre-rig, the liner cement lob or - liner top packer, if the liner lap pressure test fails (alternate plug placement per 20 AAC 25.112(i)). The following describes the work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the current well and proposed sidetrack is attached for reference.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsibl 1 The initial reviewer will check to ensure that the "Plug for Redrill"box Geologist in the upper left corner of Form 10-403 is checked. If the "Abandon" or / "Suspend" boxes are also checked, cross out that erroneous entry and V 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 Geologist 1 work) the initial reviewer will cross out that erroneous entry and initial then / it on both copies of the Form 10-403 (AOGCC's and operator's copies). / Instead, check the "Suspended"box and initial that change. Drilling Engineer 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 Stat Tech for Redrill" box, they 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, they will check the Stat Tech History tab 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, they 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 Stat Tech change 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 Stat Tech Geologists will check the "Well by Type Work Outstanding"user query Geologist in 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. STATE OF ALASKA • ALASKA OIL AND GAS CONSERVATION COM ION REPORT OF SUNDRY WELL OPERATIONS 1.

If the plug was damaged,we would have increased the contamination between the mudpush and cement to possibly 60%+contamination (suggested by modeling) and potentially not showing any set up when we ran the USIT(^'35 hrs after cement in place) We've seen this before in C-29 (PTD#214-049) in 2014,where the log showed low to no seal however we were unable to establish circulation between remedial perfs and unable to squeeze the top perfs due to pressure limitations. 3) We have concluded that HRZ has collapsed and/or cement between and above the perforations as we exceeded the Fracture gradient of both the Sag River and West Sak formations while pressure testing the perforations, indicating either set up cement or HRZ formation collapsing around the 7" casing, providing a seal that exceeds potentially exposed permeable zones(west sak and sag river) To answer your questions from the e-mail today: ➢ There are no plans to frac this well in the future ➢ The FIT was to 9.9 PPG EMW ➢ The shoe track contained contaminated mudpush/cement mixture with a high pH Thank You, Jesse From: Loepp, Victoria T(DOA) [mailto:victoria.loepp@alaska.gov] Sent: Wednesday, April 15, 2015 1:48 PM To: Rosenbaum, Jesse E Cc: Endacott, Mary S; Lastufka, Joseph N Subject: FW: PTD #215-005 03-15B 7" Casing Cement Job Jesse, • • Several questions/comments: 1. Are there plans to frac this well? 2. What was the FIT? 3. What was the cement like in the shoe track? Anytime a cement job does not go as planned and remedial operations are required,the AOGCC needs to be notified at that time and not after the fact.This has been brought to BPs attention in the past.

POOH. • RU e-line and perf 5' interval from 8936' MD—8941' MD • Set 7" cement retainer on e-line at 8850' MD for squeezing upper perfs • Perf upper interval from 8835' MD—8840' MD. RD e-line. • RIH with stinger • Stung into cement retainer and attempted to establish circulation from lower to upper perfs. • Unable to circulate/inject lower perfs. Pressured up to 950 psi (12.5 PPG EMW)with no fluid lost o No injectivity observed. Injection test proves no communication in the annulus from perfs to Sag River • Unstung from retainer and attempted to inject 10.3 ppg LSND into upper perfs o Unable to inject fluid, pressured up to 1500 psi (13.6 ppg EMW)with no fluid lost- proves no communication to West Sak 1 • Swapped well over to 8.6 ppg FLoPro SF production drilling mud and performed a negative test for 30 min on upper perfs(PASS) • POOH and PU 6.125" production drilling BHA Conclusion: We have a barrier in the annulus proven by a communication test between the perfs and a passing negative test. ➢ The evidence shows that a combination of delayed setup time for a contaminated cement and HRZ collapse behind 7" casing have isolated the cretaceous from the Sag River formation. ➢ We are currently drilling ahead in the 6.125" production section. We are not planning on running any additional logs. ➢ Please contact me if you have any questions *wellbore schematic attached Thanks, Jesse Rosenbaum Drilling Engineer i BP Exploration Alaska 0:907-564-51551 C:406.533.8984 jesse.rosenbaum[rD_bp.com 3 • 0 North America -ALASKA- BP Page 1 of 5 Operations Report - Partners (RE-ENTER- ONSH( Operator: BP EXPLORATION Event Type: RE-ENTER-ONSHORE Report: 15 Well/Wellbore No.: 03-15/03 Event Objective: DRILL SIDETRACK B Date: 05/04/2015 Well Type: DEVELOPMENT Site: PB DS 03 Job Number: 1 Contractor: DOYON DRILLING INC.

I am writing to request a change to the PTD (currently under your review)so that we can abstain from performing a Leak Off Test(LOT)at the 9-5/8" kick off point(KOP). In the submitted permit,on line 16 of the operations summary,we stated that a LOT will be performed after the 9-5/8" window is milled. Again,we reviewed BP procedures and AOGCC regulations and policies and did not find any requirement to conduct an LOT unless we drill out of the shoe. Reference- (20 AAC 25.030 (f)) Instead of performing an LOT at the window,the plan is to drill the intermediate interval using the original surface casing shoe Formation Integrity Test of(12.5ppg) 1 Engineering Justification: 1) Using the surface casing shoe FIT in a sidetrack correlates to the grassroots standard/regulation of drilling a well and using the surface(13-3/8") shoe FIT.This is further correlated because there is no cement behind casing from the KOP to the surface casing shoe which would likely result in testing the integrity of over 7900'of formation (9-5/8"TOC to 13-3/8" casing shoe) . Performing an LOT at the KOP would be similar to performing a LOT part way through drilling the intermediate section of a grassroots well which is not the goal of a LOT. 2) The original surface casing FIT for 03-15 of 12.5 ppg is greater than what is needed to drill the intermediate section of the well I appreciate your consideration for this change.

In 1990,the well had Z3 perforations added which increased water cut from 30-80%. Later in 1990, the Sag and Z4 perforations were frac'd. An attempt was made to cement squeeze the high watercut Z3 perfs, but WC did not drop indicating the Sag/Z4 frac penetrated to Z3. In 1993 the well was rotary sidetracked to the 03-15A location to get away from Z3 water production. The well continued to produce with steadily decreasing oil and steadily increasing water until 1997 when it was coil sidetracked to the current 03-15AL1 location. 03-15AL1 is a Sag only slotted liner well. The schematic shows the well to be 03-15AL1; however, it is not actually an L1 as the parent wellbore 03-15A was P&A'd prior to the CTD sidetrack. The original plan was for the well to produce as a Sag only well for — six months and then reaccess the Ivishak. This was to be achieved by a cut and pull of the liner and milling the cement cap; however,this work was never completed. Reason for Sidetrack: The artificial lift spool was blinded in 2005, and the well then produced as a nturally flowing well until 2010 when it would no longer flow on its own. The well was briefly POP'd in August 2011 w/ AL rigged up. Pressures indicated an IA x OA leak. A cut and pull of the 9-5/8" casing will be required to make the well operable again. The well is currently SI and secured with a plug at 12,067'MD due to low productivity. The well has no further value in its current location and has been released for a RST. 03-15B PTD 1 10 Dec 2014 6. • • Planned Well Summary Well Target Sag River Type Well 03-15B T e Producer Objective 103-15A API Number: 50-029-20414-01 Parent Well Status: [ Shut in.
