Dear Mr. Rixse, Enclosed please find a copy of a spreadsheet with a list of Prudhoe Bay wells that were topped-off with cement, corrosion inhibitor in the surface casing by conductor annulus through the end of 4Q 2022. Cement top-offs are executed as needed to mitigate the void space left at surface by minor cement fallback during the primary surface casing by conductor cement job. The remaining void space between the top of the cement and the top of the conductor is filled with a heavier than water corrosion inhibitor to reduce the risk of external surface casing corrosion. The attached spreadsheets include the well names, API and PTD numbers, treatment dates and volumes. 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 have any additional questions, please contact me at 564-4891 or oliver.sternicki@hilcorp.com.

Upper IBOP failed,cycled valve and test passed.Digital drill pipe pressure gauge at choke manifold was not reading correctly due to bad Battery, Electircian will change out battery. Secondary numatic operated pump does not activate until the system pressure drops below 1900psi, Parker maintenance will adjust operating pressures to meet API standard 52-6.3.5.9 prior to cutting casing to open formation. Function all components from LER,rig managers office and koomey unit. Test jt size used 4", start to test BOP @ 11:00 TO 22:00 total 11.0 HRS." Inspector Observations This Rig is starting out with good procedures for verification of accumulator integrity.They are timing the closure of stack components and using remote panel in Rig Managers office for closing and timing the closure. The only problem I witnessed was that their air pumps weren't coming on at all.After they performed their timed closure I requested they turn off the electric pump and bleed pressure to where the air pumps would actually come on. Air pumps were coming on at 1900 psi and stopping at 2500 psi. API RP 53 was read by Night WSL and Night Rig Manager. The WSL was using primary and secondary pump designation and I did not see that designation in API RP 53. I had a copy of API 53 standard November and I wanted to review that. 53 Standard states that Primary pump system shall automatically start before system pressure has decreased to 90% of the system RWP and automatically stop between 97%to 100%of RWP. The secondary pump system shall automatically start before system has decreased to 85%and automatically stop between 95%and 100%of the system RWP. I told them in this case to just make API RP happen or if it you felt better with Standard just do that but you would damn sure adjust the pumps. API RP 53, Section 12.4.1 (2Cfut s Z PLA-LA p sits tt-( - prr ,y ) "A pump system consists of one or more pumps. Each pump system (primary and s ondary)should have independent power sources, such as electric or air. Each pump system should have sufficient quantity and sizes of pumps to satisfactorily perform the following: With accumulators isolated from service, the pump system should be capable of closing the annular BOP(excluding the diverter)on the minimum size drill pipe being used, open the hydraulically operated choke valve(s), and provide the operating pressure level recommended by the annular BOP manufacturer to effect a seal on the annulus within two minutes." API RP 53, Section 12.4.5 "Electrical and/or air(pneumatic)supply for powering pumps should be available at all times such that the pumps will automatically start when the system pressure has decreased to approximately 90 percent of the system working pressure and automatically stop within plus zero or minus 100 psi of the BOP control system working pressure." 20 AAC 25.035(e)(4) (c fttt"es (�u iso st4gEe„` µ; 4,64 n "A BOPE assembly must include (A)a hydraulic actuating system with (i) ... (ii)an accumulator pump system consisting of two or more pumps with independent primary and secondary power sources and an accumulator backup system having sufficient capacity to close all BOPs and to hold them closed" PTD 2i2 —o 5 Ferguson, Victoria L (DOA) From: Ferguson, Victoria L(DOA) Sent: Friday, February 01, 2013 9:37 AM To: 'Takahiro.Kosaka@bp.com' Subject: 02-15B (PTD 212-075) Perforation Takahiro, PBU 02-15B is located in Sections 35 and 36 of T11N, R14E, UM.

Prior to picking up or running any equipment or tools in the hole, a PJSM and discussion is required to identify and note any equipment which will be run through the BOPE and is non- shearable. A risk assessment shall be performed for any equipment which is deemed non-shearable. The risk assessment must address the following: 1. Can variable bore rams seal against the equipment? 2. Can an annular preventer seal against the equipment? 3. Is a cross-over readily available to make-up into equipment? 4. Is a single joint or full stand of DP readily available to lower equipment below the BOPE stack? 5. How the equipment can be intentionally dropped down hole. 6. Are weights of equipment known so that hydraulic jacking force of wellbore pressure can be calculated. 7. Accurate and up to date shearing capabilities for the current shear rams installed is available. 8. Has each crew member been versed on individual roles and responsibilities? If there is a well control event happens with non-shearable equipment across the BOPE shear rams,the following procedure should be followed: 1. Based on the risk assessment above, gain control of the well by either: a. Closing the appropriate preventer(pipe ram, VBR, or annular)or b. Placing a sealable piece of equipment across the BOPE and closing the appropriate preventer or c. Dropping equipment and closing the Blind or Blind/Shear rams. 2. If well conditions permit, contact appropriate personnel. If not, proceed with well kill operations. This may include placing shearable equipment(i.e. drillpipe) across the shear rams by stripping in/out of the hole. 02-15B PTD Page 9 5/24/2012 02-15B RST General Operational Summary Proposed Pre-rig prep work: 1.

Intermediate Hole - Given a max cretaceous injection pressure of 9.8 ppg, this wellplan dictates the use of a 10.0 ppg LSND mud from the KOP in the West Sak sands to the top of the CM2. With the pore pressure for the CM2 & CM1 to be estimated at 10.2 ppg, the mud weight will be increased to 10.4 ppg to drill those members of the Colville and on to the 8-1/2" TD into the TSAG. (NOTE: The max pore pressure for the Put River sands and the Sag River sands are 9.5 ppg and 7.8 ppg respectively.) B. Production Hole - The Ivishak in this area is expected to be under-pressured at 7.2 ppg EMW. This interval will be drilled with a 8.5 - 8.8 ppg reservoir drill-in fluid. II. Lost Circulation/Breathing A. Intermediate Hole - While no major lost circulation is expected in this interval of the well, breathing and/or lost circulation is a possibility due to the moderately shallow KOP on this well which exposes all formations from the KOP to the TSAG to drilling ECD's associated with the planned 10.4 ppg mud density. B. Production Hole - The lost circulation risk for this interval of the well has been characterized as "low". III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is 42 bbls, and for the production section is infinite. B. Integrity Testing Test Point Test Depth Test type EMW(lb/gal) 9-%"window 20'-50' from the 9-%"window FIT 10.8 minimum 7" shoe 20'-50' from the 7" shoe FIT 8.8 minimum IV. Hydrogen Sulfide While there are no wells on DS 02 with >100 ppm H2S, operations should adhere to the guidelines in the ADW"Hydrogen Sulfide" SOP. V. Faults - no mapped faults. VI. Anti-Collision Issues A. After the gyro work in the 8-1/2" hole, all wells will pass Major Risk analysis. B. 3 Put River wells (the 02-27A and 02-23A producers plus the 01-08A injector)will be SI while drilling the intermediate section of this well.

According to the our PP/FG work done for DS-02, the most likely PP from the top of the Sag to TD (which includes the Shublik) is 7 2 ppg and therefore, drilling this section of the well with our standard 8 5- 8.9 ppg drill-in reservoir fluid will provide a sufficient over-balanced condition for safe drilling operations. The maximum PP of 9 9 ppg for the Shublik as indicated in our request for the PTD, is a calculated value for this"shale"which has no flow potential and therefore, should not be considered a drilling hazard. 2. The casing design work for this well is covered under our Base of Design document for our USH Ivishak wells (see attached).

When you drill into the Shublik after setting 7" are there any concerns or is formation so tight that it doesn't raise concerns with mud weight? 2) Do you have Burst , Tension , and collapse calculations for casing.

C Guy, As it relates to our conversation this morning as to the final condition of the existing 20"and 13-3/8" casing stubs after removing the old wellhead, please note the following plan as it is currently detailed in the"draft"wellplan: 1. To remove the old wellhead, set back the BOP and make internal WACHS cut on the 13-3/8" casing below the hanger and remove the 13-3/8" casing hanger and wellhead from above that cut. With the wellhead removed, make an external cut on the 20" below the lower most casing head and remove same (will/may require some excavation / plug the 13-3/8" casing looking up with absorbent wrapped in wire to prevent debris from falling down-hole). With the 20" removed from above the cut, cut-off the excess 13-3/8" casing above the 20" stub leaving both casing stubs at basically the same level and fill any 20"x 13-3/8" void with cement. If you have any questions and/or concerns, please advise. -jr John G Rose BP Staff Engineer Anchorage,AK rosel l@bp corn 907/564-5271 Office 907/748-5223 Cell 907/243-8813 Home 6/11/2012 Page 1 of 2 Schwartz, Guy L (DOA) From: Schwartz, Guy L (DOA) Sent: Thursday, June 07, 2012 1:58 PM To: 'Rose, John G (ASRC)' Cc: Regg, James B (DOA) Subject: DS 02-15B (PTD 212-075)and Parker 273 John, Can you supply a better diagram of the new BOP for Parker 273?We don't have a separate BOP file here at the Commission for this rig yet. If you can supply the detailed drawings for the diverter/BOP/choke manifold etc. we can file it. We do have several emailed documents but they are quite old and may not be up to date to reflect any changes to the rig since then. Will this be the first well for the rig? Your drilling schedule indicates in will be number 2 for the rig afer DS 02- 12.... if so the BOP testing cycle may be at 7 days till the rig has several BOP tests under belt and is running smoothly. Below is a generalized requirement for new rigs working in Alaska. ... this of course applies to Parker 272 also. AOGCC requires details about rig and will need to do a thorough rig inspection prior to it being put in service for BP. I'll give you the benefit of learnings from AOGCC"s review and inspection of other recent rigs new-to-Alaska over the past 5 years: - Design and fire rating for BOPE control lines; - Protection of critical well control systems from freezing (e.g., BOPE hydraulic control lines); - Pressure rating for equipment; - Exposed degasser and piping that would be susceptible to freezing; high potential for plugs to form; - Insufficient#of accumulator pumps; regulations require 2 or more pumps with independent primary and secondary power sources; - Gas detection, mud handling, rig watch (pit volume totalizer) equipment; often not rigged up when AOGCC does initial rig inspection; typically run into problems with personnel on rig not familiar with equipment;gas detection system must incorporate separate and distinct audible and visual alarms are required for combustible gas and H2S; there is a non-regulatory standard for visual alarms that has evolved in Alaska (combustible/methane—red light; H2S—yellow light); - Nitrogen backup for accumulator; - Firewall to shield accumulator and primary BOPE controls; - Choke and kill lines assembled with improper connections(hammer unions are not allowed); - Diverter system, including annular preventer, vent line configuration/orientation, knife valve, vent line size and distance from closest ignition source. Other items: - Certifications for all BOPE (rams, annular,valves, high pressure piping, controls) and copies of test charts done during certification inspection/testing by qualified 3rd party; - Documentation from most recent major inspection of BOP stack and related components per API RP 53, Section 17.10.3; 6/7/2012 Page 2 of 2 - Well control certifications for Toolpusher, driller and others who participate in drilling and workover operations; - Pressure testing procedure for BOPE; procedure for using Nitrogen backup; - If modifications to the high pressure piping system, provide information confirming welding has been done by qualified welders/pipefitters and include report documenting non-destructive testing; opportunity must be provided to AOGCC to witness pressure testing (commissioning of modified high pressure piping) - If the BOPE stack is incorporating a set of blind-shear rams, include actual shear testing data and photos of cut pipe; reference API RP 53, Sections 12.3.2, 17.5.6(blind-shear rams not required for surface stacks, but several operators have transitioned to including blind-shear ram in their BOP stack) Feel free to contact me if you have questions.
