S' nature of Officer =Public ,�pf!���!es: 3-20-2o AlOftr i'L,j Title of Officer Date: April 25, 2019 Subject: Z-20 Fracture Stimulation From: David Wages Engineer, BP Alaska o: 907.564.5669 c: 713.380.9836 To: AOGC Commission Attached is BP's proposal and supporting documents to fracture stimulate the Kuparuk interval of well Z-20. The Ivishak interval has no remaining value and has been shut in since January 2017 due to uncompetitive rates (single -digit IOR when it's online). The Kuparuk penetration of Z-20 is in an ideal location for offtake, so this is an attractive recomplete candidate. This is already a gas -lifted producer, so no surface piping work is required. All Kuparuk vertical wells are frac'ed, so this well will need a . post -rig frac to increase productivity and ensure competitive rates. . We are requesting a variance to sections 20 AAC 25.283, a, 3-4 which requires identification of fresh water aquifers and a plan for basewater sampling. Please direct questions or comments to David Wages Summary of Work This will be a conventional fullbore frac after a recomplete to the Kuparuk interval Affidavit of Notification (20 AAC 25.283, a, 1) Partners notified 3/14/2019: ConocoPhil lips ExxonMobil Chevron Department of Natural Resources Plat Identifying Wells (20 AAC 25.283, a, 2, A -B) •.1�4 27 - Per the plat above, there are no water wells within '/2 mile of the subject well.

Per Aquifer Exemption Order No. 1 dated July 11, 1986 where Standard Alaska Production Company requested the Alaska Oil and Gas Conservation Commission to issue an order exempting those portions of all aquifers lying directly below the Western Operating Area and K Pad Area of the Prudhoe Bay Unit for Class II Injection activities. Findings 1-4 state. 1. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit do not currently serve as a source of drinking water. 2. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit are situated at a depth and location the makes recovery of water for drinking water purposes economically impracticable. 3. Those portions of freshwater aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit are reported to have total dissolved solids content of 7000 mg/I or more. 4. By letter of July 1, 1986, EPA -Region 10 advises that the aquifers occurring beneath the Western Operating and K pad areas of the Prudhoe Bay Unit qualify for exemption. It is considered to be a minor exemption and a non -substantial program revision not requiring notice in the Federal Registrar. 12G Per the above findings, "Those portions of freshwater aquifers lying directly below the Western Operating and K Pad Areas of the Prudhoe Bay Unit qualify as exempt freshwater aquifers under 20 AC 25.440." thus allowing BP exemption from 20 AAC 25.283, a, 3-4 which requires identification of freshwater aquifers and establishing a plan for basewater sampling.

(20 AAC 25.283, a, 11) EiT�tkal ~'�, z�z , BP's technical analysis based on seismic, well, and other subsurface information available indicates that there are five mapped faults that transect the Kuparuk interval and enter the confining zone within the 'fi mile radius of the production and confining zone trajectory for Z-20. Fracture gradients within the confining zone (Kalubik and HRZ) and will not be exceeded during fracture stimulation and would therefore confine injected fluids to the pool. The HRZ and Kalubik in this area are predominantly shale, with some silts with an estimated fracture pressure of —13.5 ppg. No faults were crossed while drilling Z-20. Fault #1-6 intersect the production interval and confining zone within the 'h mile radius. Their displacements, sense of throw and zone in which they terminate upwards in are given below. Faults Throw Upward Fault Termination Zone Fault #1 60' DTW Colville Fault #2 30'DTE HRZ Fault #3 110' DTS Colville Fault #4 75' DTN Colville Fault #5 15' DTE HRZ The drilling inclination through the Kuparuk is —46 degrees from vertical, at an azimuth of —83 degrees. The closest point of entry for the frac is 580 feet away from the nearest fault (fault 1) in the Kuparuk. The primary horizontal stress direction in this area is 30 degrees W of N, and the fault is due east of the well (see plat 2 for fault, frac orientation, and frac half length). The frac will propagate approximately perpendicular to the wellbore and nearly parallel to nearby faults. Summary Hydraulic Fracture Program (20 AAC 25.283, a, 12) (Detailed Program and Pump Schedule included) Maximum Anticipated Treating Pressure: 3500 psi Maximum Allowable Treating Pressure: 4500 psi Anticipated half length: 250' ' Anticipated height growth: 90' Each frac will initiate at their corresponding perforations. The perforations are located at: Frac Stage MD, feet TVD, feet 1 8055'-8105' 6612' -6646 - Estimated TVD Top and Bottom of Frac: 6608'-6670' Estimated MD Top and Bottom of Frac: 8050'-8140' The above frac dimensions were calculated using modeling software. Surface pressure is calculated based on a closure pressure of —0.62 psi/ft or —2700 psi, this combined with the anticipated net pressure to be built, hydrostatics and the friction gives a surface pressure of 2500 psi at the time of flush. The frac height is primarily based on closure pressure differences between the confining shale layers and the unconfined sandstone reservoir. Average confining layer stress is anticipated to be —0.7 psi/ft. Half length is based on confining layer stress as well as leak -off and formation modulus. Given the values, the above half lengths are calculated. Pressure Test Information (20 AAC 25.283, a, 7) Per the frac program, the both the tubing and the IA will be pressure tested. The IA will be tested to 3500 psi and the tubing will be tested to 4000 psi. PRV setting procedures and annulus monitoring: Maximum Allowable Treating Pressure: 4500 psi Stagger Pump Kickouts between: 4050 psi and 4250 psi (90% to 95% of MATP) Global Kickout: 4250 psi (95% of MATP) IA pop-off set pressure: 2600 psi (75% of MIT -IA) Treating line test pressure: 6000 psi Sand Requirement 90,000# 16-20 CarboLite, 50,000# 16-20 CarboBOND Minimum Water Requirement 1500 bbls (pump schedule: 1063 bbls) IA Hold Pressure 2400 psi (IA pop-off @ 2600 psi) Monitor and maintain open to atmosphere There are three overpressure devices that protect the surface equipment and the wellbore from overpressure. Each individual frac pump has an electronic kickout that will kick the pumps into neutral as soon as the set pressure is reached. Since there are multiple pumps, these set pressures are set between 90% and 95% of the maximum allowable treating pressure. There is the primary pressure transducer in the treating line that will trigger a global kickout which will kick all the pumps into neutral. Finally, there is a manual kickout that is controlled from the frac van. All three of these shutdown systems will be individually tested prior to high pressure pumping operations. Additionally, the treating pressure, IA pressure and OA pressure will be monitored in the frac van. Ir Z-20 Rig Up Tim'ra \ memoxl rm \'� \ veIl � t�qR ■ I A..d.

The Kuparuk penetration of Z-20 is in an ideal location for offtake, so this is an attractive recomplete candidate. This is already a gas -lifted producer, so no surface piping work is required. All Kuparuk vertical wells are fraded, so this well will need a post -rig frac to increase productivity and ensure competitive rates.

See Appendix A - CT Screenout FCO Procedure Page 14 of 9 Appendix A - CT Screenout FCO/Millout Procedure i. This is a generic FCO/millout procedure for a post screenout FCO. Specific info such as amount of proppant left in tubing and estimated sand top will not be known until after the event. ii. The objective of this procedure is to get the well cleaned to continue frac operations or to prep the well for POP. in. Recommend reviewing PE Manual section for Coiled Tubing Fill Cleanouts for specifics on reversing rates, speeds and CT loading. Planned Procedure b. MIRU CT c. MU BHA. d. RIH down to estimated sand top and begin cleaning out with slick 1 % KCL. e. Continue down to —8000' CTMD. At this point we are 100' above the uppermost perforations. Ensure CT is clean as it is expected that returns will begin to fall off as the nozzle nears the sleeve. If returns begin to fall off, reducing BHP by lowering rate may keep returns at a manageable level. f. Slowly continue to clean out until returns fall off to —80%. If returns are still good even after the nozzle is past the sleeve (not likely but possible), continue to clean out2e48A i. led. g. Gfiee IBR is elear oF sand, R" 1 and pull IBP. h. FP to 2500'. i. Pump a gel pill at surface out to the tanks to ensure CT is clean if necessary. j. RDMO. Page 15 of 9 Appendix B - Test Separator Additional Flowback Procedure 1. MIRU ASRC. RU equipment to in a manner that allows CT to RU if an additional FCO is necessary. 2. POP the well to ASRC at minimum choke. Flow the initial returns to the flowline as long as the shake -outs meet the returned fluid/solids management guidelines. 3. Limit flow to 500 bpd 4. If solids are < 1 %, increase the production rate to 1000 BLPD. 5. Flow bottoms up and sample for solids production. If solids are still below 1 %, allow well to flow to 1500 BLPD. Flow bottoms up and sample for solids production. If solids are still below 1% continue to increase the flow rate in 500 BPD increments. The objective is to achieve maximum drawdown. Watch returns and do not continue to open choke if solids > 1 %, allow well clean up before choke is opened further. 6. Once at FOC, stabilize the well for 4 hrs. Obtain a 3 hr purge, 8 hr welltest.

History and current status: Z-20 is an EWE Ivishak gas lifted producer that was last worked over in 1991. It is completed with two separate tubing segments jointed at 10,341' MD by a seal assembly just above a 4-1/2" x 9-5/8" packer. The 9-5/8" cement job was 400 bbis class G cement, putting the TOC at 5600' MD (assuming 40% volumetric washout). This is -2465' above the TKUP but -300' below the Schrader. No losses were noted in this interval. The Ivishak interval has no remaining value and has been shut in since January 2017 due to uncompetitive rates. ' Scope of Work: The primary objective of this RWO is to recomplete as a Kuparuk producer. The Ivishak reservoir will be abandoned during pre -pulling unit operations. The MASP for the Ivishak is 2745 psi. \ Pre -Pulling Unit Prep Work: 1. W: PPPOT-T and PPPOT-IC. Function LDS. 5 2. S: Pull GLVs & set DMY GLVs. 3. F: nj Fullbore P&A,N oc�•ooi'PlC Vj)rK �/ 4.

Please note: The lower "reservoir' section of the well will be cemented with 46 bbls of cement pumped via fullbore with a planned TOC of 10350' MD. This step will be preceded by a tubing punch just below the upper packer and another tubing punch just above the lower packer. These punches, along with the perforations through the 4-1/2" and 7" at 11158-11239' will provide uniform coverage and a cement top 800' above the top open perf. Additionally, we will place a 1300' cement plug in the TBG and IA (90 bbls) directly above the packer via the open GLM at 10303' MD with a planned TOC of 9000' MD. Casing will be tested to 3000 psi.

Please note: The lower "reservoir" section of the well will be cemented with 46 bbls of cement pumped via fullbore with a planned TOC of 10350' MD. This step will be preceded by a tubing punch just below the upper packer and another tubing punch just above the lower packer. These What is the BOPE test pressure? On step #5 'Post rig Work': If BPXA is planning to fracture under this sundry AOGCC will need considerably more detail. I presume BPXA will be submitting a separate fracturing sundry. Please confirm.

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 piace and meet the requirements of form 10-404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Anna Dube, at 659-5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator i ~ BP Exploration (Alaska ) Inc.
