Dear Mr. Lau, 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 06/09/2025. 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.

On August 14th 2018, a plug was set at 9995'MD to shut off injection to the lowest 2 perf intervals and instead force the injection into the uppermost 3 perf intervals. Forcing injection in this manner improves the injectivity of the rock by cooling it down. After sufficient injection to these 3 perf intervals, the plug was pulled and another plug was set at 9941'MD on September 22"d 2018. This forced the injection into the uppermost 2 perf intervals. This plug was pulled on November 11th 2018, and another plug was set at 9905'MD to force the injection into the uppermost pert interval. On December 30th, this plug was pulled out, restoring all 5 perf intervals open to injection and an IPROF was conducted to gather data on the injector conformance.

I discussed the possibility of getting that data from the rig team and Parker Drilling, but TOTCO system on Parker 272 is not currently equipped with the flow-line gas reading. The measurement is only taken real-time from the gas sensor and is not recorded in the rig data. We are currently working with TOTCO to install the flow-line gas reading and record the data in the TOTCO system but is not currently in place I was under the impression that Parker 272 had the same setup as Doyon 25 which has the capability to record those readings and monitor through TOTCO. Please let me know if there is anything else I can provide.

Please see the reference information below. N-Pad History N-Pad is located in the north-central portion of the Prudhoe Bay Field BP has done extensive Pore Pressure/Fracture Gradient studies throughout Prudhoe Bay. A study on N-Pad has been conducted (updated October 24, 2012.) Here is some N-pad history and key findings from this study: • Influx Events: "There have been no documented influx events at N-Pad." • Breathing: "There have been no documented breathing events at N-pad." • Mud Logs/ Connection Gas / Gas Cut Mud: Mud logging was not a common practice during the development of Prudhoe and most of the mud logs we have are paper copies from the late 1970's/ early 1980's. The mud log from N-01 is from 1970 and does not contain connection gas data. Background gas is the only well documented data from the N-01 mud log. N-01 is the only instance of gas cut mud on N-pad, drilled in 1970, and shows gas cut mud at 4320' TVDss and 6381' TVDss. These are in the Ugnu and Colville, respectively, and lie below the planned surface interval for N- 28i. • Shallow Gas:There have been no documented shallow gas events on N-pad • Shallow water flows:There have been no documented shallow water flows on N-pad • Disposal: Disposal near N-pad is below the surface casing interval. The GC-2E disposal well injects into the UG3 and is 4200' away from the N-28i target well path at the injection horizon depth. Injection into GC-2E was relatively constant and modest from 2011 to 2013. In the past 6 months, disposal has been minimal. GC-2C has not been active since 2007. ML pressure for UG3 was set at 9.3ppg and the max PP from the pad PPFG validation report is 9.5ppg. • The most two recent wells drilled on N-Pad: o N-29i was drilled in September this year(2014) with no shallow hazards encountered, gas or hydrate related. o N-30 was drilled in October this year(2014) with no shallow hazards, gas, or hydrate related issues. o N-27i was drilled in September 2007 with no shallow hazards encountered, gas or hydrate related. A review of wells that have been drilled within 500'of the proposed surface casing shoe depths has been performed: 5 • • • N-28i 500' Radius at Surface Casing Point 0 • I r I I I e , I L N-24 was a grassroots producer drilled by Nabors 28E in June of 1992.The drilled a 13"surface hole to 3210' MD (3001' TVD) with no issues. Had to work through a bridge at 2100' MD but able to work through. 10-3/4" casing was run to TD. Surface casing was cemented with 356 bbls of 12.1 ppg arctic-set lead cement and 71 bbls of 15.8 ppg class G bbls of cement and did not achieve cement to surface.A top job was performed and 20 bbls of arctic set cement was pumped to achieve cement to surface. No signs of shallow hydrocarbons,free gas, hydrates or shallow water aquifers. 6 , . . • • Alaska Region _ .. by PPFG Prediction Status 4irltuns ta. 2012 .,, 4 N-Pad \''''.--,,-7— , , _ _ i ki(l..)

I discussed the possibility of getting that data from the rig team and Parker Drilling, but TOTCO system on Parker 272 is not currently equipped with the flow-line gas reading. The measurement is only taken real-time from the gas sensor and is not recorded in the rig data. We are currently working with TOTCO to install the flow-line gas reading and record the data in the TOTCO system but is not currently in place I was under the impression that Parker 272 had the same setup as Doyon 25 which has the capability to record those readings and monitor through TOTCO.

Please see the reference information below. N-Pad History N-Pad is located in the north-central portion of the Prudhoe Bay Field BP has done extensive Pore Pressure/Fracture Gradient studies throughout Prudhoe Bay. A study on N-Pad has been conducted (updated October 24, 2012.) Here is some N-pad history and key findings from this study: • Influx Events: "There have been no documented influx events at N-Pad." • Breathing: "There have been no documented breathing events at N-pad." • Mud Logs/ Connection Gas / Gas Cut Mud: Mud logging was not a common practice during the development of Prudhoe and most of the mud logs we have are paper copies from the late 1970's/ early 1980's. The mud log from N-01 is from 1970 and does not contain connection gas data. Background gas is the only well documented data from the N-01 mud log. N-01 is the only instance of gas cut mud on N-pad, drilled in 1970, and shows gas cut mud at 4320' TVDss and 6381' TVDss. These are in the Ugnu and Colville, respectively, and lie below the planned surface interval for N- 28i. • Shallow Gas:There have been no documented shallow gas events on N-pad • Shallow water flows:There have been no documented shallow water flows on N-pad • Disposal: Disposal near N-pad is below the surface casing interval. The GC-2E disposal well injects into the UG3 and is 4200' away from the N-28i target well path at the injection horizon depth. Injection into GC-2E was relatively constant and modest from 2011 to 2013. In the past 6 months, disposal has been minimal. GC-2C has not been active since 2007. ML pressure for UG3 was set at 9.3ppg and the max PP from the pad PPFG validation report is 9.5ppg. • The most two recent wells drilled on N-Pad: 3 o N-29i was•ed in September this year(2014) with no shallow hazards encountered, gas or hydrate related. o N-30 was drilled in October this year(2014) with no shallow hazards, gas, or hydrate related issues. o N-27i was drilled in September 2007 with no shallow hazards encountered, gas or hydrate related. A review of wells that have been drilled within 500'of the proposed surface casing shoe depths has been performed: N-28i 500' Radius at Surface Casing Point I 500 0 N-24 was a grassroots producer drilled by Nabors 28E in June of 1992.The drilled a 13" surface hole to 3210' MD (3001' TVD)with no issues. Had to work through a bridge at 2100' MD but able to work through. 10-3/4" casing was run to TD. Surface casing was cemented with 356 bbls of 12.1 ppg arctic-set lead cement and 71 bbls of 15.8 ppg class G bbls of cement and did not achieve cement to surface.A top job was performed and 20 bbls of arctic set cement was pumped to achieve cement to surface.No signs of shallow hydrocarbons,free gas,hydrates or shallow water aquifers. 4 , • • [ _ ..._____ --_ iiv_ --_ . i------: 0 bp Alaska Rion Prediction Status fatJune 14, 2012 — N-Pad ....... ..._ _ t ... r a . -, i .

N-28i well is currently scheduled to be drilled by Parker„272 beginning 10/30/14. The maximum anticipated surface pressure from the permeable reservoir sands is 'psi (assuming the predicted max PP of 7.25 ppg at TD). Parker 272 is equipped with 5000 psi rated four preventer BOP stack (3 rams and an annular). The rams will be tested to 4000 psi and annular to 3500 psi.An Area of Review has also been included for this proposed injector and is included in the permit. The plan for N-28i includes the following: 1. The pre-rig well work will include installation of the conductor,welding of the landing ring, install of the lined cellar box,and prepping of the location for the rig to move over the well. 2. MIRU Parker 272 and function test the diverter. 3. MU 12-1/4"bent housing motor drilling assembly. Drill to the deepest shale in the SV3 sands at-3218' MD. 4. Run 9-5/8"surface casing and cement to surface. - 5. NU BOP and test. 6. Drill 8-1/2" hole to TSGR at 9733' MD. 7. Run and cement 7"casing to at least 1500'above casing shoe. 8. Drill 6-1/8" production hole to a planned final TD at the top of the Kavik shale at-10450' MD. 9. Run and cement a 4-1/2" production liner. 10. Run a 4-1/2"completion tubing string,sting into liner tieback sleeve and set production packer. 11. RDMO well.

Annulus Integrity Comments mile of any point along the planned well path within the reservoir section After a tubing swap RWO in May-2004,the new tubing passed an MIT-T to 3500 psi, N-21A 650 and also passed an MIT-IA on the rig to 3500 psi proving the integrity of the 9-5/8" production casing down to the production packer. The annulus pressure plots look well behaved,as well. A RWO in July-2008 swapped the tubing and replaced the top 2000'of 9-5/8" production casing. On the rig the well passed a 3500 psi MIT-IA confirming the N-12 830 integrity of the new and old 9-5/8"production casing down to the production packer. The annulus pressure plots do show allow IAxOA communication,but it is small enough to be manageable by bleeds. This slight communication is very improved since the 2008 RWO. N-22 680 The N-22A bore was a CTD sidetrack that kicked off in the reservoir section,so no change in annulus between N-22 and N-22A. See N-22A for more detail. The annulus below—7400'MD was abandoned in 2007 when the well was rig sidetracked to N-22B. The N-22A CTD liner and tubing tail were abandoned via a cement plug pre-rig,and passed a subsequent MIT to 2000 psi. A pre-rig CMIT-TxIA passed to 3500 psi proving the 9-5/8"competency down to the old production packer at 9712'MD. On the rig in 2007 the tubing was pulled and the 9-5/8"casing N-22A 680 down to 1800'was replaced,and an EZSV was set at 7240'MD. The well was sidetracked,and after new tubing was installed,an MIT-IA to 4000 psi passed on the rig,confirming the integrity of the newly modified annulus. This old new 9-5/8" passed an MIT proving its competency above 7240'MD. An additional MIT-IA to 3000 psi passed in 2008 as well,and two OA repressurization tests since then have showed no/minimal buildup rate. The following information is provided as it relates to the relevant cement jobs on the wells within 1/4 mile of this injection well. 2 l N-21- N-21 was drilled in 1985. The 9-5/8" Intermediate casing string was cemented with 360 bbls of 13.2 ppg lead cement followed by 35.6 bbls of Class "G" tail cement with no losses. !"1 L k 5,»:2 Assuming 30% excess, that places TOC at 5,011' MD. N-21 7" liner was later P&A'd with for the N-21A sidetrack. 115 bbls of "G" (3000 ft) balanced plug was placed in the liner. N-21A was a single string high-angle sidetrack that was drilled in 1998. The 4.5" liner was fully cemented. The plug did not bump on strokes. 15 bbls of cement were circulated off the top of the liner. The initial pressure test on the 4.5" failed and a 3.5" cleanout run with a motor BHA was run to cleanout cement stringers and the motor backed off and left on bottom. A CIPB was set above the motor and the 4.5" liner passed a pressure test to 3500 psi. TOC at 10,412' MD. N-12 - N-12 was drilled in 1981 as a 3 string grassroots producer. This 13-3/8" surface hole was cemented with 712 bbls of 14.9 ppg "Permafrost" Cement and did not achieve cement to surface. A top job was performed w/ 1-1/4" pipe with an additional 35 bbls and achieved cement to surface. The 9-5/8" Intermediate casing was a 2-stage job run and cemented with N-28i PTD Page 3 8/14/2014 0 • 288.5 bbls of 16 ppg class "G". The plug did not bump. The second stage was pumped through a DV packer and 25 bbls of additional cement was pumped. Tested to 3000 psi. A USIT run in 2008 showed TOC at 2650' MD. The 7" Production liner was run and cemented with 20 bbls of 16 ppg / class "G" cement. With no losses during the cement job and the plug bumped on strokes and cement was circulated off the top of the liner. Tested to 3000 psi. A RWO was performed in 2008 to repair a casing leak in the 9-5/8" casing. The 9-5/8" casing was cut and pulled to surface from 2080' MD. A new 9-5/8" casing string was tied back and cemented to surface with 145 Bbls of 15.8 class "G". N-22 - N-22 was drilled as a 3-string producer in 1985. It is currently has OA x IA communication. The 13-3/8" Surface casing was run and cemented at 2700' MD with 579 bbls of 12.2 ppg permafrost "E" cement and achieved cement returns to surface. The 9-5/8" Intermediate casing was run to 10,118' MD and cemented with 336 bbls of 13.2 ppg Lead cement followed by 41 bbls of class "G". Assuming 30% excess, TOC is 4,826' MD. The 7" production liner was run and fully cemented with 69.2 bbls of class "G" cement. N-22A - was a CTD sidetrack that was drilled in 1998. The 2-3/8" liner was cemented with 18.4 bbls of 15.8 class "G" cement and circulated excess cement off of TOL. The wellbore was P&A'd for a rotary sidetrack in 2006. Service coil pumped 23 bbls of 15.8 ppg class "G" cement at 1:1 with 100% returns. TOC was tagged at 9512' MD and pressure tested to 3500 psi.

To avoid the risk of plugging the flow line with large rocks and wood encountered while drilling surface hole, it is requested to drill without a flow paddle for the first portion of the surface hole. While the flow paddle is removed from the flow line, PVT alarms will be used and the pit levels accurately monitored for any pit gain. Also,a visual check will be made during connections by looking down the riser to ensure the well is not flowing. After returned debris that could plug the flow line diminishes the flow paddle will be reinstalled. 2. Due to the geometry of the production interval,the production packer must be set outside 200'of the producing interval.This is a variance from the regulation to set the production packer within 200 ft of the producing interval.

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.

N-28i PTD Page 13 8/14/2014 • N-28i Drilling Hazards and Contingencies POST THIS NOTICE IN THE DOGHOUSE I. Well Control A. Surface Hole—the interval is normally pressured. No shallow gas is expected in the interval, and there are no reported incidents of offsets running into overpressured zones or shallow gas. Planned mud weight will range from 8.7-9.0 ppg. B. Intermediate Hole-the planned mud weight will be ranging from 9.4—10.3 ppg depending on depth of drilling. Sufficient mud weight will account for: 1. Potential cretaceous injection pressures(9.3 ppg max). 2. Predicted Colville pressures(9.65 ppg max). • 2. Sag River pore pressure(7.1 ppg max). 3. HRZ and Kingak shale stability(10.1-10.3 ppg). • C. Production Hole -The Sag River and Ivishak formations in this area are expected to be under-pressured at 7.1 ppg EMW. This interval will be drilled with a 8.6 ppg reservoir drill-in fluid. II. Lost Circulation/Breathing A. Surface Hole- N-pad has a history of heavy concentrations of gravel and some wells have required top jobs to get cement to surface. Drilling with properly maintained MMO mud has alleviated many surface hole problems recently. Lost circulation is considered a moderate risk. • B. 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 exposing formations from the 9-5/8" casing shoe to the TSGR to drilling ECD's associated with the planned 10.1-10.3 ppg mud density. An ECD hardline of 11.8 ppg EMW will be set while drilling the intermediate interval. C. Production Hole -There is a history of lost circulation in the production hole at N-pad. Most of these events are associated with crossing faults. There are no planned fault crossings in the production hole, but if lost circulation is encountered,follow the mud program's lost circulation decision tree. III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the frac gradient required for a 25 bbl kick tolerance in the intermediate section is 11.6 ppg, 12.63 ppg for a 50 bbl kick tolerance, and 8.83 ppg for an infinite kick tolerance in the production section.
