The well was first sidetracked with CTD in 2007 as a Zone 1B producer. After multiple add-perf stages, the well was shut-in for annular communication with a production casing leak. The low remaining value of the well did not justify a cement squeeze to put the well back on production. A few small remaining lenses can be produced from the parent at a later date. The casing leak has already been scheduled for remediation in preparation for the new sidetrack. Proposed plan: G-27B will exit from well G-27A by the Nordic 1 Coiled Tubing Drilling rig on or around June 15, 2015. The G-27B sidetrack will perform a single-string window exit through the existing 3-3/16" liner. Kick-off will occur in lvishak Zone 2A and target Zone 2A and 1B reserves. The proposed sidetrack is a -2,330' horizontal Ivishak Zone 2A/1 B producer which will access a -45 acre reserves target south of G-Pad. The first-800' of the lateral is expected to be in Z2A above HOT. A fault will be crossed that is expected to force the remaining -1600' of lateral into Z1 B above HOT. The lateral will be completed with a 2-3/8" L-80 liner which will be cemented and perforated. This Sundry covers plugging the existing G-27A perforations via the G-27B liner cement lob or liner top packer set post-rig (alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. ze ci,,J ec f well fe1 Ov1 -vi� ce .ctc 4 rec 041tel, �,� ? iri• 1 �t c moss` rec.et/7- g r�es3/1` Cine 4 /14 r w � ,/eP /1�I0�7`1S, f�'‘e, ��r to O cll� mcF, 4'/3 wi`�t.^ ,1 /ec/`,•(l 1kL%' alt/w 4'- /n �� lPCov�y o� , l�ietl �vr � , Pre-Rig Work(scheduled to begin May 15, 2015) 1.

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 check the "Suspended" box and initial that change. V 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.

History: G-27A was coil sidetracked in May 2007 as a horizontal"toe out"of its parent well in SW G-pad. The well was sidetracked to provide a horizontal completion at the base of the reservoir to improve Z1B off take while staying as close to the HOT as possible.The sidetrack targeted the Zone 1B in the parent well fault block in addition to Zone 1B in an up thrown fault block.The initial perforation strategy called for perforating 830 feet of Zone 1B in the newly tapped fault block.Initial well tests showed the well to be making 3000+bopd at solution GOR.Early on, as oil rates quickly declined, gas began to cone into the well quickly before leveling out at rates near 30 mmscf/d.For the next year G-27A remained online, at which point it was shut in for high Page 1 of 8 a GOR in August 2008.Attempts to cycle the well showed it to have poor recharge and it was subsequently left shut in. In June 2009, in order to restore G-27A to fulltime production, coil isolated all existing perforations with a CIBP and added Zone 1B perfs in the original G-27 fault block.The new perforation intervals were selected with the following considerations: do not perforate sands in communication with the fault, maintain maximum TVD standoff to the GOC, and stay out of sands affected by MHO/HOT.In all, over 120' of Zone 1B perfs were added to the heel of the well just above the MHO/HOT. Unfortunately, G-27A was unable to flow post-perf and numerous attempts to flow the well with PBGL failed.A geologic post-appraisal suggested that the addperfs may have actually been in the MHO/HOT and thus the reason for the well not flowing. To try and re-establish flow, a perforation program in November 2009 targeted new Zone 1B intervals that were closer to the fault in addition to an interval of Z1B in the build section of G- 27A, which had only minimal offset from the parent. When the logging tools were retrieved from the lubricator, prior to shooting any new perforations, it was noted that they were covered with a heavy tar. Coil perforated over 90' of new Zone lB interval,but once again, G-27A did not flow when it was POP'd with PBGL. A HOT-to-POP,which pumped 175 bbls of crude immediately following the job, also failed to get G-27A kicked off. As a third attempt to get G-27A to flow,another 90' of perfs were shot in May 2010. Cleaner intervals were selected for perforation in a final attempt to get the well to flow. The perforation intervals were also selected by choosing areas closer the main fault and choosing areas a few feet shallower(TVD)than the perforations shot previously. Attempts to POP G-27A through backflowing and dirty PBGL failed once again. In September 2010, in a final attempt to get the well to flow, SL went and set a deeper GL design. After bringing the well online with PBGL, G- 27A finally began to flow. Initial rates showed the coming online at 1200+bopd at 6K GOR. G- 27A stayed online fulltime 3 months before hitting marginal GOR's.Most recently,the well has shown declining ability to cycle on and it looks to be shut in fulltime if no remedial wellwork is performed soon. In February 2011, G-27A was called in for high IA pressure and subsequently failed a TIFL on monitor and declared inoperable. As part of the diagnostic work, a caliper showed the tubing to be in good to fair condition with a max wall penetration of 30%. After dummying off of GLV's, an MIT-IA passed to 2500 psi in March 2011. The well has since been reclassified as operable. In March 11, 2013, a Pprof was run and perforations were added at 10,550'-10,580' MD, 10,590- 10,620' MD, and 10,633'-10,663' MD. In April 2013, a preparation for a tree changeout was being executed. A PPPOT-T passed to 5,000 psi. Slickline ran in the hole and set a PX plug @ 8,316' MD. A CMIT-TxIA was executed and failed the pressure test to 2,500 psi. The PX plug was pulled and set at 8,184' MD. Another CMIT-TxIA was executed and failed. On April 7th, 2013,a MIT-T passed to 3,000 psi. Failed an MIT-IA to 2500 psi and LLR was 3.4 GPM. An LDL was run on May 1st, 2013 and a leak was found at 3,290' MD. For questions or comments please call Lea Duong at 564-4840 (w)or 720-951-7238 (c). Page 2 of 8 MMIM • G-27A Procedure SLICKLINE 1.

Rig up pump to the tubing and pump 20 bbls of diesel down the Tubing taking returns up the IA. This will create an under balance and allow the sealant pill to be sucked into the IA. Close wing valve. 11. Mix 6 bbls of 8.83 Flo-Seal I in Seal-Tite Mixing tank. Attach tank to the 9 5/8" annulus and open wing valve and bleeding back the diesel in the tubing, suck the Sealant pill into the annulus. 6 bbls will provide 138' of coverage in the 9 5/8" x 5 1/2" annulus. 12. Displace the Flo-Seal Pill down the IA with 135 bbls of diesel while taking returns up the tubing. This will put the base of the sealant pill 1 bbls above the leak site. Consider choking tubing back to 1,000 psi as soon as sealant is in the IA. Displace to leak depth. 13. Shut in the tubing and pressure up the IA to 1,000 psi with Diesel. Keep 1,000 psi on the tubing until a seal is achieved. Once a Seal is achieved at 1,000 psi hold the pressure for 4 hours. 14. When there is no leak on the IA for 4 hours at 1,000 psi stage the pressure up on the IA to 2,500psi in 500psi increments per the Seal —Tite rep on location. Page 4 of 8 • • 15. Once a seal on the IA has been established at 2,500 psi let the Sealant cure on the IA for 72 hours. 16. After the 72 hour cure time turn the well back over to the Wells Group.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

(5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer Downhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log provided by Schlumberger GR CNL dated 20 May 2007 per Mike Teague with BP Exploration (Alaska), Inc. (8) The sidetrack was drilled from G-27 through a milled window in a 5 1/2 inch liner. Top of window 10703 ft.MD (8975.6 ft.TVDSS) Bottom of window 10708 ft.MD (8975.9 ft.TVD5S) (9) Tied to G-27 at 10400 feet to 10500 feet MD (8954 to 8961 feet TVDSS). (10) The interval from 12660 feet to 12700 feet MD (8977.6 feet to 8982.2 feet TVDSS) was not logged due to sensor to bit offset at well TD.
