Report Of Sundry Well Operations (10-404) June 7, 2018 To Whom it May Concern: Attached please find the Report Of Sundry Well Operations for Repair Well (Packer Squeeze) covered under Approved Sundry#318-019 for Well PBU 15-30B, PTD #210-037. The packer squeeze was completed on 3/7/18 but the MITIA still failed on two attempts nearly a month apart. The LLR appeared to be 0.5 - 1.1 gpm @ 2700 psi. The IA re- pressurization has been fixed but the well is still Not Operable due to failing MITIA with apparent TxIA. On 5/15/18 an acoustic LDL was performed with some "potential anomalies" noted at the TOC in the IA and at the GLM. However, the LLR into the IA during the logging went from -0.5 gpm/2700 psi to -0.05gpm/2700 psi. As well, the pressure loss into the IA was as low as -90 psi/45 minutes at the end of pumping. On 5/26/18 ab MIT-IA failed 4 attempts. Further diagnosis will be pursued to identify a new plan of action to fix 15-30B. Sincerely, BP Exploration (Alaska) Inc. P.O.

Application for Sundry Approval (10-403) September 19, 2017 To Whom it May Concern: Attached please find the Sundry Application for Packer Repair with BiSN Seal Treatment for Well 15-30B, PTD # 210-037. Sincerely, BP Exploration (Alaska) Inc. P.O. Box 196612 Anchorage, AK 99519-6612 Attachment: Form 10-403 15-30B Packer Repair with BiSN Metal to Metal Seal Intervention Engineer Ryan Thompson (907) 564-4535 Production Engineer Paulina Meixueiro (907) 564-5971 Well: 15-30B History 15-30B is a natural flow producer originally completed in 2010. The well had an LTP replacement on 12/3/16 that cut so much gas that the well was not able to lift on its own. Given that there is no gas lift lines at Drillsite 15, the well was temporarily put on production by hooking a nearby well into the IA. The well flowed for three months and gas rates did not increase. A portable test separator was brought in and tested the well without temporary gas lift and the well died. On 7/21/17 10' of perforations were added for in situ gas lift. Well was put on production and tested with a portable test separator on 8/11/17. The IA pressure increased to at 2200 psi immediately after bringing the well online, which make us believe there is a cement channel connecting the recent perforations with the IA. A plug was set above the new perforation and pressure tested, proving that the tubing is in good condition. The failing CMIT-TXIA liquid leak rate is 0.2 bpm at 2750 psi. A cement bond log shows that the perforations were —300 below top of cement, however the new perforations could have caused the cement let loose in the IA. A traditional cement packer repair would require to set a composite plug that would be difficult to push down given the small diameter below the packer area. Objective This well has been selected for the BiSN technology as one of three candidates to prove up this technology in BP Alaska's operations. Inclination at the packer is 52 degrees and estimated temperature is 173°F. This repair would be less expensive than the traditional cement squeeze. After the packer repair is done, a straddle system with orifice sub will be installed over the Sag perfs to control the gas entry to improve the GOR of the well and bring it back to the 200+ bopd ]OR level. Procedural Steps Slickline 1. Pull WRP, drift for heater and packer; pull dummy gas lift Sta #5 and replace it with a circulating valve with screen. Eline & Fullbore 2. Pumpers rig up to IA and pump BiSN bead slurry 3. Eline run CBL to confirm the beads at the desired interval, run BiSN Heater, melting beads in place 4. After 3 hours perform a MIT -IA to 3000 psi 5. Set WRP below Sag perfs 6. Confirm injectivity to Sag perfs 7. Pull WRP, drift to deviation, set straddle with orifice over the Sag perfs to control the amount of gas from this interval Slickline 8. Pull WRP, run live gas lift valves Operations & DHD 9. Pop well 10. DHD to TIFL and long-term monitor to verify tubing integrity 1>V4 • CAM a-wo wo, nra, L-50, u= 5651- I-( 10608' ',r SAFETY NOTES- WELL ANGLE > 70• @ 11334'. CMT WHLHEAD FAC A(;iiM TOR .

Well was put on production and tested with a portable test separator on 8/11/17. The IA pressure increased to 2200 psi immediately after bringing the well online, which indicates a channel from the Sag perfs into the IA. An MITT passed to 2500 psi in September of 2017. The MITIA failed however, with a liquid leak rate of 0.2 bpm at 2750 psi. This well has been selected for the BiSn technology packer squeeze and a Sundry application for that work has already been submitted, however this project has been delayed by various technical difficulties. A conventional cement packer squeeze is proposed as a reliable alternative to the BiSn plug. - Current Status The well is currently classified as "Not Operable" by BP and is shut-in due to the leak. Y Objective The objective of this job is to perform a packer squeeze and seal off the leak. Procedural steps Slickline 1. Pull WRP. Eline 2. Set CBP @ -10,200' MD. Coiled Tubing 3. Pump packer squeeze with -30 bbls Class G cement. Mill out Cement/CBP after cement reaches -500 psi compressive strength. TOC in IA after packer squeeze expected to be -9600' MD. • Cement Type/weight: Class G 15.8 ppg batch mixed.

The coil depth was 3500'. The well was shut in using the choke and the 7" annular. A well head pressure of 1300 psi was observed. A pit gain was observed. The BP CTD town engineers were called, and the situation discussed. The well has remained shut in while the plan forward is finalized. The expected plan is to return the end of coil to just above the CTD window at 10,700'. Well bore fluids will be bled to to an external flow back with de- mister to maintain a constant well head pressure while running in the hole. Once at the target depth, the well will be circulated with geovis drilling mud as per standard kill procedure until the wellhead pressure returns to zero. Additional circulation will be performed to ensure the influx has been removed. As the wellbore influx is indicated to be gas, no additional weighting of fluid is anticipated. If this procedure does not result in the required drop in wellhead pressure, the well will be killed using a bullhead technique with drilling fluid. If you require any additional information, please contact me. Gary T.

The well 15 -30 was originally drilled and completed in September, 1992. CTD first rigged up to drill the 15 -30A sidetrack in June 2002, but did not complete it due to problems during the primary cement job. CTD returned to 15 -30 in January 2003 and • sidetracked the well placing 1120' of Zone 1A/1B perforations inside the horizontal 2 -3/8" liner. The well stayed fulltime until spring 2007 when it attained LP MGOR and began to cycle. A neutron log from September 2007 showed the GOC to be right at the TZ1 B (8662' TVDss). The well began experiencing erratic production after the CTU MCNL logging. A November 2007 SL drift with sample bailer came back empty. The rates recovered in early 2008 and 15 -30A continued cycling with decent on time until early 2009 when the GOR crept up. All attempts to swap it to the HP system have been unsuccessful and there are currently no good wellwork options left to pursue. The present low on time of 20% is only expected to decrease due to 15 -30A's lack of ability to flow in the HP system. Utility of well 15 -30 will be restored by sidetracking away to maximize standoff from POGC. As part of the CST screening process, the well passed an MITIA to 3000 psi and failed the MITOA to 2000 psi on 8/29/09. The parent well had a liner lap leak / IA squeeze in April 1998 that left -1400' of a cement sheath / collar between 9600' - 11032' MD. A PDS caliper that was logged on 01/08/2010 showed the sheath to be absent. A Cement Log run on March 23, 2010 showed top of cement behind in 3'h" tubing x 7" liner at 10,265' MD. The caliper showed the rest of the 4.5" x 3.5" tubing to be in good to poor condition with respect to mechanical damage. The sidetrack, 15 -30B, is scheduled to be drilled by Nordic 2 starting on June 1 2010. This horizontal lateral will target Ivishak Zone 1A/1B. The perforations in the parent well will be abandoned with a 3 monobore packer whipstock placed inside the 3Y2' 13Cr -80 tubing at 10,980' MD. The "B" sidetrack lateral will exit the parent well at -10,980' MD in the Ivishak Zone 2 and drill a -3,120' lateral to a TD of 14,100' MD. The sidetrack will be completed with a solid, cemented and perforated 2 -3/8" L -80 production liner. The following describes work planned.

Mud Program: • Well kill: 8.6 ppg seawater / brine. • Milling /drilling: 8.6 ppg Geo -VIS or biozan for milling, new 8.6 ppg Geo -VIS for drilling. Disposal: • All Class II drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS 4. • All Class I wastes will go to Pad 3 for disposal. Hole sizes: 3.0" bi- center hole: 10,980' MD - 14,100' MD Casing Program: • 2 -3/8 ", L -80 4.70# STL 10,710' MD - 14,100' M D • A minimum of 13.0 bbl 15.8 ppg cement will be used for liner cementing. (Assuming 3.0" bit size and TD at 14,100', with 20% excess in the open hole interval) • TOC planned at 10,710' MD (top of 2 3/8" liner). • If liner lap fails, a liner top packer will be run. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 2500 psi. Directional • See attached directional plan. Maximum planned hole angle is 95 deg at 12,119' MD. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 26,100 ft • Distance to nearest well within pool -190 ft (well 15 -07B) Anti - Collision • 15 -07 598' (ctr - ctr distance) Status: Plugged and Abandoned • 15 -07A 630' (ctr - ctr distance) Status: Plugged and Abandoned • 15 -07B 190' (ctr - ctr distance) Status: Plugged and Abandoned • 15 -07C 866' (ctr - ctr distance) Status: Oil Producer Shut -In • 15 -16A 176' (ctr - ctr distance) Status: Plugged and Abandoned • • • Logging • MWD directional, Gamma Ray and Resistivity Togs will be run over all of the open hole section. • A cased hole GR /CCL/CNL log will be run. Hazards • DS 15 is not an H drill site. H levels are typically less than 20 ppm. • The maximum recorded H level on Drill Site 15 was 40 ppm on well 15 -20 (07/01/2006). • The maximum recorded H level on 15 -30 was 26 ppm (03/23/2008). • The lost circulation risk for 15 -30B is considered low to medium. Overall risk of significant losses during drilling is considered to be low for this well. We are drilling into a fault intersection zone which might indicate a medium risk but we have no mapped fault crossings and no significant losses ( >100 bbls) into Zone 1 have occurred in the area previously which is why we have gone with a rating of low risk for loss circulation. Reservoir Pressure • The reservoir pressure is estimated to be 3,278psi at 8,420 TVDss (7.5 ppg equivalent). • Max. expected surface pressure with gas (0.10 psi /ft) to surface is 2,436 psi Eli Vazquez CTD Engineer CC: Well File Sondra Stewman/Terrie Hubble TREE = FMC WELLHEAD= McEVOY ACTUATOR = OTIS 70 UH 2202 410 1 5-3 oA S OTES: ORIGINAL 15 -30A P &A, CHEM CUT & PULLED LNR @ 11610'.

DIRECTIONAL Other Services Line 1 Remarks (1) All depths are Measured Depths (MD) unless otherwise noted. (2) All depths are Bit Depths unless otherwise noted. (3) All True vertical Depths ( TVDSS) are subsea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to 109 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 Primary Depth Control (PDC) log provided by schlumberger GR CSG above the Kick off Point off 10839 feet MD dated 01 Nov 1992 per Jennifer Flight with BP Exploration (Alaska), Inc. The MWD data is not the PDCL for well 15 - 30B. (8) The sidetrack was drilled from 15 - 30 through a milled window in a 3 1/2 and 7" inch liners. Top of window 10840 ft.MD (8391.9 ft.TvDSS) Bottom of window 10848 ft.MD (8396.4 ft.TvDSS) (9) Tied to 15 -30 at 10801 feet MD (8370.6 feet TVDSS). (10) The interval from 14079 ft to 14110 ft MD (8670.5 ft. to 8671.4 ft. TVDSS) was not logged due to sensor to bit offset at well TD.
