The results given are estimates based on calculations produced by a computer model including various assumptions on the well, reservoir and treatment. The results depend on input data provided by the Operator and estimates as to unknown data and can be no more accurate than the model, the assumptions and such input data. The information presented is Schlumberger's best estimate of the actual results that may be achieved and should be used for comparison purposes rather than absolute values. The quality of input data, and hence results, may be improved through the use of certain tests and procedures which Schlumberger can assist in selecting. The Operator has superior knowledge of the well, the reservoir, the field and conditions affecting them. If the Operator is aware of any conditions whereby a neighboring well or wells might be affected by the treatment proposed herein it is the Operator's responsibility to notify the owner or owners of the well or wells accordingly.

After monitoring the decline for about 15 minutes, seeing a slow decline,the decision was made to move forward with the designed pump schedule. The designed schedule consisted of a 0.5 PPA scour of 16/30 sand, followed by the main proppant ramp of 16/20 CarboLITE from 1PPA flat followed by a 1-8PPA ramp. In this treatment report the proppant ramp is shown with multiple short steps (0.25PPA increments),as this is the only way to achieve the desired proppant ramp in the current version of FracCAT. After the proppant ramp 4 flat steps followed, being 8, 10 and 11 PPA of 16/20 CarboLITE and then a 12PPA CarboBond Lite. The treatment design called for a total of 149,200 lbs of 16/20 CarboLite and 60,880 lbs of 16/20 CarboBond Lite (curable resin coated CarboLITE). The job treated very well until we reached about 5PPA prop on surface. At this point,friction was causing the surface pressure to gradually increase. Once 8PPA on surface was reached,the decision was made to cut rate by 5 bpm.As soon as rate dropped,the pressure started to climb and spiked to 4,600psi (700psi jump). Expecting a screen out, proppant was cut at the chief and rate dropped to 29 bpm. A few seconds after the call to cut sand was made, pressure stabilized. At this point the supervisor had the chief operator open the gates,to resume the job,at the same time the POD hopper was starting to go empty,this lead the POD gate to open, leading to a 13PPA proppant spike. The POD auto corrected to the setpoint of 9PPA. Once proppant was filling up the hopper again, pump rate was increased as well.While increasing the rate back to 35 bpm,the prop con fluctuated a little while the gates were taking control. Once rate and prop con lined out,the remainder of the job treated very well. While transitioning to LVT from linear gel,the slurry rate input was not switched from the electromagnetic flowmeter on the POD to the pump strokes on the frac pumps.This occurred at about 15:30 on the PRC Main Treatment Plot in Section 4. This period lasted about 40 seconds and the average mechanical pump rate was 18 bpm. This accounts for a total of 12 barrels of fluid. The job was shutdown at 1,934 bbl of total slurry. If the 12 bbl are added to this, it gives a final shutdown of 1,946. Flush was called at 1,772 total bbl and the flush volume was 177bb1. Taking into account flush volume,the shutdown, excluding underflush, should be 1,949 bbl. With a modified shutdown of 1,946 bbl of total slurry,the well had 3 bbl of underflush. This resulted in 213,163 pounds of proppant being placed into formation. The treatment was replayed in FracCAT,with the resulting values shown in this report and plots. . s 0 Schlumberger Client:BP Exploration Alaska Well:S-44 Formation:Kuparuk C District:Prudhoe Bay Section 2: DataFRAC, As Measured Pum • Schedule As Measured Pump Schedule Ste Slurry Slurry Pump Fluid MaxrProp Prop #p Step Name Volume Rate Time Fluid Name Volume Proppant Name Conc Conc Mass (bbl) (bbl/min) (min) (gal) (PPA) (PPA) (Ib) 1 Load hole 58.6 14,3 6.1 WF128 2027 0.0 0.0 0 2 Fluid Check 43.4 21.6 2.0 YF128FIexD 1823 0.0 0.0 0 3 Calibration 75.0 26.5 2.8 YF128FIexD 3150 0.0 0.0 0 4 Scour 100.0 28.9 3.5 YF128FIexD 4111 16/30 Sand 0.6 0.0 2,295 5 Calibration 25,0 34.8 0.7 YF128FIexD 1044 0.0 0.0 0 6 Displacement 185.7 35.9 5.5 WF128 7791 0.0 0.0 0 Stage Pressures & Rates Average Slurry Maximum Slurry Average Treating Maximum Treating Minimum Treating Step# Step Name Rate Rate Pressure Pressure Pressure (bbl/min) (bbl/min) (psi) (psi) (psi) 1 Load hole 14.3 22.2 3373 4509 338 2 Fluid Check 21.6 25.5 3879 4184 3067 3 Calibration 26.5 28.1 3697 4078 3351 4 Scour 28,9 32.6 3428 3822 3044 5 Calibration 34.8 36.1 3992 4066 3822 6 Displacement 35.9 36.3 3559 4037 994 As Measured Totals Slurry Pump Time Clean Fluid Proppant (bbl) (min) (gal) (Ib) 487.7 20.6 19945 2295 Average Treating Pressure: 3581 psi Maximum Treating Pressure: 4509 psi Minimum Treating Pressure: 338 psi Average Injection Rate: 29.2 bbl/min Maximum Injection Rate: 36.3 bbl/min Average Horsepower: 2588.3 hhp Maximum Horsepower: 3578.1 hhp Maximum Prop Concentration: 0.6 PPA • !

My name is Tyson Shriver. I am 18 years of age or older and I have personal knowledge of the facts stated in this affidavit. 2. I am employed as an Engineer by BP Exploration (Alaska) Inc. ("BPXA") and I am familiar with the Application for Sundry Approvals to stimulate the S-44A Well (the "Well") by hydraulic fracturing as defined in 20 AAC 25.283(m). 3. Pursuant to 20 AAC 25.283(1), BPXA prepared a Notice of Operations regarding the Well, a true copy of which is attached to this Affidavit as Attachment 1 ("Notice of Operations"). 4. On November 20, 2015, the Notice of Operations was sent to all owners, landowners, surface owners and operators within a one-half mile radius of the current or proposed wellbore trajectory of the Well. The Notice of Operations included: a. A statement that upon request a complete copy of the Application for Sundry Approvals is available from BPXA; b. BPXA's contact information.

Well S-44A is a recently drilled rotary sidetrack that was completed August 2015. The well is constructed with an open hole sliding sleeve/swell packer completion and targets the Kuparuk C sands. The well was brought online and tested with results showing high water cuts between 89-94%. A fracture stimulation for the toe of the well penetrating the C3 sand was planned prior to drilling to improve productivity in the low perm sand. Subsequent coil work will be done to shut sleeves producing water. The objective of this program is to perform a fracture stimulation to improve well performance. We are requesting a variance to sections 20 AAC 25.283,a,3-4 which require identification of fresh - water aquifers and a plan for basewater sampling. Please direct questions or comments to Tyson Shriver • • Affidavit of Notification (20 AAC 25.283, a, 1): Partners notified 11/20/2015: ConocoPhillips ExxonMobil Chevron Department of Natural Resources Plat Identifying Wells(20 AAC 25.283,a, 2): *See Figure 3 in section "Location of Wells and Faults(20 AAC 25.283, a, 10-11)" Exemption for Freshwater Aquifers(20 AAC 25.283,a, 3-4): Well S-44A is in the West Operating Area of Prudhoe Bay. 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 that 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. 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 require identification of freshwater aquifers and establishing a plan for basewater sampling. • • Detailed Casing and Cement Information (20 AAC 25.283,a,5-6A): Well S-44A was spudded 07/16/2015 The parent bore of well S-44A had a 12-1/4" hole drilled to 3145' MD where 9-5/8",40#, L-80, BTRS casing was run (casing shoe at 3130' MD) and cemented in place with 404 bbls of Cold Set 11112.2 ppg lead and 88 bbls of 15.8 ppg Class G cement. Prior to exiting the 9-5/8" casing for the S-44A sidetrack, a plug was set at 2682' MD and passing pressure tests were performed (250psi for 5 min and 3000 psi for 30 min). A whip stock was then set and a 8-1/2" window was milled from 2661'—2678' MD. Another 19' of formation was drilled to 2697' MD and leak off testing was completed with 9.3 ppg mud to 910 psi surface pressure at 2661'TVD (15.78 ppg LOT). A 8-1/2" intermediate hole was drilled to 10,019' MD where 7", 26#, L-80,Vam Top HC casing was run (casing shoe at 10,016' MD) and cemented in place with 150 bbls of 11.5 ppg lead Litecrete cement and 20 bbls of 15.8 ppg tail Class G cement. Casing was successfully pressure tested to 250 psi for 5 min and 3500 psi for 30 min. Cement and 21' of new formation were drilled out with a 6-1/8"bit to 10,040' MD where a FIT was performed with 10.1 ppg mud (740 psi surface pressure, 6755'TVD, 12.2 ppg EMW). A 6-1/8" production hole was drilled to TD at 12,080' MD. Uncemented 4-1/2", 13.5#, 13CR-80, HYD 521 liner was run to 12,078' MD. The liner consists of six sliding sleeves and six water swell packers. The completion assembly consisting of 4-1/2", 12.6#, 13CR-85 Vam Top tubing was run to 9876' MD with the packer at 9747' MD. *See Mechanical report and cement evaluation Table 4 in section "Location of Wells and Faults (20 AAC 25.283, a, 10-11)"for conformance with 20 AAC 25.283, a, 6B) Pressure Testing(20 AAC 25.283, a,7): Table 1—Tubing and Production Casing Pressure Testing Tubing Pressure Production Casing Differential Pressure Date (psi) Pressure (psi) (psi) TBD 3500 0 *3500 TBD 2000 4000 2500 *The tubing will be pressure tested to 3500 psi which is greater than 110%of max differential pressure (2800 psi) during fracture stimulation per 20 AAC 25.283, c, 2. • • Accurate Pressure Ratings of Tubulars and Schematic(20 AAC 25.283,a,8): Wellbore Schematic 91,1-11K-All FPA: i-44A SA(1 iY NOMS- S-WELL ANGLE s 79"r 10170'""'MAX I ACTUATOR- �r.KC1t C.

The blue line indicates the approximate fracture length and orientation in the toe of S-44A. The above plat shows faults and wells within a 1/2 mile radius of the subject well. There are two faults that are of concern while performing fracturing operations (Fault 1 & 2). Fault 1 is a 28' downthrown SW fault that intersects the S-44A wellbore at"'11,000' MD (6717'TVDss). The upper extent of the fault is estimated to be'x6250'TVDss and lower extent—7200'TVDss (cuts some Colville, HRZ, Kalubik, Kuparuk and some Miluveach). Sufficient standoff from planned fracture initiation and vertical extent of the fault terminating in shale zones reduce the chance of Fault 1 serving as a flow channel for frac fluids into other zones. Fault 2 lies due East of S-44A wellbore trajectory and is parallel to both the primary fracture plane and subject well. Fracture orientation and predicted half-length should avoid containment of frac fluids during pumping operations. An approximate 1000 ft standoff exists between the toe of 5-44A and S-100 wellbore. Sufficient stand- off along with fracture orientation and predicted half-length will keep fracturing fluids from reaching well S-100. All wells within %z mile radius of the subject well and there mechanical designs can be seen in Table 4. • • J Y O O O co 3 3, m .800 .e ••- a o-cito CO E as 111 2 a ! ti 16 0 on �{ O O pp�(p�l N d O l�0 l�D lD ,,-6tD t0. 0 t0 t0 lip .to l�D t'^0 l0 C •— oC = r a) U C i_ v C U LI ,y I� n M M CO N tD a) a�-1 U N 0 000 W N - 1 V 'a U C as p V in to V R u1 tD cto t✓ 'L (O U • 2 tn N a) jno cu U U 4-, U 0 'j = 00 00 c C c 00 b0 •C µ- L v E 2 CU vv v v v v L O 0- m E v -o E E E E E -o E -o E N •V 3 0 Zig u o o > > > c o c p o o m m 0 D 0 0 7, Opo 7,- 2 o O C a) > z > > > > > > > O i i a-I � -0 I O C 0) L co 8 _c CO j V - O , O co Lo V M 00 t^O .�-I — i." 3 VI = .t?), . a) U Lri t to m Ln 1,1 tD CO .N-I U X U '§' 2 ed ad of '0 cd ed a6 oi tri ti X C) o 0 0 _ • i M CO Oil O ti MCU • Ol oCrl tp0' r-IN O O 3 C O •tr p co� W co� co^ t.D t.0 00 n totto CDD too W {n •0 3 d - - a) a J (^ i N O LL .� tD ao o o �Lin u Ui M 00E CS c V 0 8 0 a' (-7: 8 ° A a a Z +.'

Since there are multiple pumps, these set pressures are staggered between 90%and 95%of the maximum allowable treating pressure. 2)A primary pressure transducer in the treating line will trigger a global kickout that will shift all the pumps into neutral. 3) There is a manual kickout that is controlled from the frac van that can shift all pumps into neutral. 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. Based on a regional stress map,the maximum horizontal stress in the Kuparuk sands is determined to ✓ run N/S(5-15°W of N). The heel and lateral of the well are drilled perpendicular to the maximum horizontal stress meaning the induced fracture will also be perpendicular to the wellbore. Frac Dimensions: TVDss,feet Frac Half-Length,ft Top 6675 ^'250 ft 1 Bottom 6850 The above values were calculated using modeling software. Maximum Anticipated Treating Pressure:4500 psi Surface pressure is calculated based on a closure pressure of"'0.6 psi/ft or—4000 psi. Closure pressure plus anticipated net pressure to be built(500 psi) and friction pressure minus hydrostatic results in a surface pressure of 5500 psi at the time of flush. 4000 psi(closure)+500 psi(net)+3900 psi (friction)-2900 psi(hydrostatic)=5500 psi(max surface press) The difference in closure pressures of the confining shale layers determines height of the fracture. Average confining layer stress is anticipated to be^'0.7 psi/ft limiting fracture height to 175 ft TVD. Fracture half-length is determined from confining layer stress as well as leak-off and formation modulus. The modeled frac is anticipated to reach a half-length of—250 ft. rc/ • • S-44A Wellwork Procedure Date: 11/18/2015 From: Tyson Shriver- Intervention Engineer To: Wireline Ops Superintendent David Wages - Intervention Engineer Well Services Ops Superintendent Coil and Well Testing SR WSL Est.

For discussion on questions about cutting fault please see attached slides. One clarification I would like to make is that the perforation interval open to fracturing operations I previously sent is wrong. My apologies and please disregard previous interval. The sleeve we will be fracing through is located at 11,688' MD (6702'TVDss). This sleeve lies between TD of S-44A at 12,078' MD (6692'TVDss) and the first swell packer at 11,395' MD (6708'TVDss). Discussion seen in slides is based on this interval. Again sorry for the confusion and thank you for the feedback. Please let me know if you need anything else.

The thick, blue,straight lines represent potential 500-foot long fractures at the top and bottom of the affected perforated interval (250-foot long frac wings extending from each side of the wellbore) that are oriented approximately in line with the principal stress direction in this area. The long, brown line segments represent Faults 1 and 2. The short, horizontal brown line segment represents 500'of distance on the map. On my map,the distance from the southern edge of a potential 250-foot long fracture wing at the top of the perforated interval to Fault 1 is only on the order of 50'. Admittedly, I've located the faults on my map by proportioning the locations of these faults using BP's structure map(from the application)and the formation intercepts and TD locations of nearby wells. I'm concerned about the proximity of the potential fracture to Fault 1 and the possibility of this fault to allow out-of-zone migration of frac fluids. • Did PBU S-44A loose circulation while drilling in this portion of the borehole? • How do my results compare with the detailed results from your geoscience group? • Please provide a discussion that includes how Fault 1 was identified,the accuracy of the location of the fault within the PBU S-44A wellbore, how the vertical displacement of the fault was determined,and how shallowly and how deeply this fault cuts through the geologic section (provide formation names and MD and TVD for the top and bottom of the fault).

How will the proposed fracturing interval(s) be isolated from the fault that cuts the S-44A wellbore at about 11,000' MD? (As I read BP's application,the production liner is uncemented. What assurance does BP have that the swell-packers provide seals that are adequate to prevent fracturing fluids from migrating along the wellbore to the fault plane?) From past experience on the L3 and L1 Lisburne wells with sliding sleeve/swell packer completions,good indication has been seen that swell packers are successfully isolating zones. Each time a new sleeve was opened to a different zone, a change in bottom hole pressure was seen indicating isolation from adjacent zones. BP has subjected swell packers to fracing differential pressures with success. In S-44A,two swell packers isolate the annulus of the wellbore from the cutting fault improving the likelihood of isolation from the fault. Swell packers are very reliable for zonal and fault isolation. If a sudden loss of treating pressure occurs during stimulation contingent steps will be followed (see below). 2. If the induced fracture wings extend 250'from the wellbore,what is the closest approach (in feet)from the end of the nearest induced fracture to Fault 1? The closest approach of a 250'wing of the fracture will come to Fault 1 is^'400 ft. 3. What is the closest approach (in feet)from the end of the nearest induced fracture to nearby Fault 2? The closest approach of a 250'wing of the fracture will come to Fault 2 is^'750 ft. 4. What is BP's contingency plan if a sudden loss of fracturing treating pressure occurs? During pumping operations, pressures indicate fracturing out of zone, linkage to a fault or any other activity leading to loss of treating pressure, pumping operations will be shut down immediately. Issues will be identified and dealt with accordingly prior to proceeding with operations. 5. Is that contingency plan clearly stated in BP's Plan of Operations and in BP's application? This contingency is stated in the detailed pump procedure but is not outlined in BP's application.

Or am I missing something? Please provide the top of proposed fracturing interval and the base of proposed fracturing interval as measured depths and true vertical subsea depths. Sleeve#1 at the toe of the well is the target for fracture stimulation. The sleeve is set at 11,688' MD and 6702'TVDSS. Apologies for not clearly stating that. Two swell packers straddle the sleeve @ 11178' MD and 11395' MD (6717'TVDSS and 6708' TVDSS respectively). The interval between these two swell packers will be the only open perforations to the fracturing ,. operations. / �$ 4 e A r4 sk-u 2n�. cc /7� 2.,/5- // /Z•i0 •/S- Please explain how BP estimates the measured depth for the top of cement for each casing string 6r liner using volumetrics so that AOGCC can confirm BP's estimates. The 7" intermediate casing was cemented with a total of 170 bbls of cement(150 bbls LiteCrete and 20 bbls Class G). Full returns were seen during the entire job. Assuming 30% washout and an annular volume of 0.0226 bbl/ft,the top of cement is estimated to be 4750' MD and 4175' TVDSS.

Standard Alaska Production Company, by letter of May 16, 1986, requested that the Oil and Gas Conservation Commission 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. 2. Notice of an opportunity for a public hearing on July 21 , 1986, was published in the Anchorage Times on June 13, 1986. 3. Neither a protest nor a request for a public hearing was timely filed. Accordingly, the Commission will, in its discretion, issue an order without a public hearing. 4. A copy of Standard Alaska Production Company's request was forwarded to the U.S. Environmental Protection Agency (EPA) - Region 10, on May 21 , 1986, in conformance with Section 13 of the Memorandum of Agreement, between the Alaska Oil and Gas Conservation Commission and EPA, effective June 19, 1986. • • FINDINGS: 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 that 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 a 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 nonsubstantial program revision not requiring notice in the Federal Register. 5. The Western Operating Area and the contiguous K Pad Area constitute a compact land parcel which can readily be described by governmental subdivisions. CONCLUSION: 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. NOW, THEREFORE, IT IS ORDERED THAT the portions of aquifers on the North Slope described by the 1/4 mile area beyond and lying directly below the following tracts of land are exempted for Class II injection activities only.

Dear Mr. Chatterton: Based on a July 7, 1986, telephone conversation between Lonnie Smith and Harold Scott, I understand there were no comments during the public comment period regarding the proposed exemption. Therefore, we concur with your decision to exempt the aquifers beneath the Western Operating Area of the Prudhoe Bay Unit for Class II injection activities only.

Anchorage, Alaska 99501 RE: Standard Alaska Production Company Aquifer Exemption Request . May 16, 1986 Dear Mr. Chatterton: As you know, the UIC permit application submitted by the Standard Alaska Production Company (formerly Sohio Alaska Petroleum Company) to EPA on June 6, 1984, indicated there were no underground sources of drinking water (USDW's) at the Prudhoe Bay Oil Field (Western Operating Area). However, in their May 16, 1986, aquifer exemption request to AOGCC, it appears there are USDW's in the area. We will be contacting the operator for clarification as to when they became aware of the existence of USDW's. We will keep you informed of our findings and any subsequent actions. In accordance with our Memorandum of Agreement, EPA has conducted a preliminary review of the aquifer exemption request. We believe that the subject aquifers qualify for an exemption. Our final concurrence/ non-concurrence with your decision will be based on the results of your detailed evaluation of the exemption request and any additional information developed through your public comment process. This action is considered to be a minor exemption and a "nonsubstantial program revision" and will not require notice in the Federal Register. Sincerely, 7-4/ Robert S.

Leemhuis, ODE Date: February 11, 2015 Re: S-44A Permit to Drill The planned S-44A well is currently scheduled to be drilled by Parker 273 in May 2015. The rotary sidetrack is a U-shaped Kuparuk producer. S-44 will be abandoned and jet cut pre-rig. The 4.5"tubing will then be pulled with the rig. Another jet cut will be made in the 7" casing and pulled out. An EZSV bridge plug and whipstock will be set in the 9-5/8" casing at -2,747'. The intermediate hole is planned as a liner with the shoe set in the top of the Kuparuk River Formation. The production interval will be completed with a cementless and sliding sleeve liner. --- The maximum anticipated surface pressure from the Kuparuk River with a full column of gas from TD to surface is -2,680 psi (assumes 9.5 ppg as max pore pressure and 0.1 psi/ft gas f gradient). This well will be drilled by Parker 273 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams will be tested to 3,500 psi and the annular will be tested to 3,500 psi. A detailed operations summary is included with the permit application. Below is a brief summary of planned drilling operations. 1. Move in and rig up Parker 273 • 2. Nipple up BOPE and test to 3,500 psi 3. Pull 4.5"tubing from -3,200' MD to surface 4. RIH and jet cut 7" casing at-3,000' MD and pull casing to surface. 5. Set EZSV and whipstock, mill window in 9-5/8" casing. Perform LOT. 6. Drill 8-3/4" intermediate section to TKC4 casing point 7. Run and cement 7" liner(TOC will be at 7" liner top). Pressure test liner to 3,500 psi. 8. Drill 6-1/8" production interval to target Kuparuk C2, C3, C4 sands. Geosteer as required. • 9. Run 4-1/2" production cementless production liner with sliding sleeves. Pressure test to 3,500 psi. 10. Run 4-1/2" production tubing. Set the production packer and pressure test to 3,500 psi. 11.

I3P Exploration (Alaska) Inc. (BP), by letter received May 14, 2015, requested an administrative waiver of the spacing requirements of Rule 1 of Conservation Order No. 457B-Corrected (CO 457B-Corrected) to drill, complete, and produce development oil well Prudhoe Bay Unit No. S-44A (PBU S-44A) at spacing of less than 40 acres within the Aurora Oil Pool. 2. Pursuant to Rule 10 of CO 457B-Corrected, the Alaska Oil and Gas Conservation Commission (AOGCC) may administratively waive the requirements of any rule or administratively amend any rule in CO 457B-Corrected as long as the change does not promote waste or jeopardize correlative rights, and is based on sound engineering and geoscience principles. 3. Owners, landowners, and operators of properties within 1,000 feet of the proposed well are BP, Chevron U.S.A. Inc., ConocoPhillips Alaska, Inc., ExxonMohil Alaska Production, Inc., and the State of Alaska. Pursuant to 20 AAC 25.055, BP sent notice of the application to these parties by certified mail on May 14, 2015. BP provided evidence of certified mailing (i.e., Domestic Return Receipts) on May 19, 2015. 4. No protests to the application, comments, objections or request for hearing were received. 5. Because BP provided sufficient information upon which to make an informed decision, the request can be resolved without a hearing. FINDINGS: 1. BP owns and operates the Aurora Oil Pool within the Prudhoe Bay Field and the PBU S- 44A development oil well, which are located in the North Slope Borough, Alaska. 2. PBU S-44A will be an onshore development oil well with a surface location 4,502' from the east line and 4,242' from the south line of Section 35, T1 2N, R12E, Umiat Meridian (U.M.). The top of'the productive interval is expected to lie 4,345' from the east line and 847' from the south line of Section 27, T12N, R12E, U.M. The bottom-hole is projected to be 4,176' from the east line 2,828' from the south line and of Section 27, T12N, R12E, U.M. • • Conservation Order 4573 Corrected-004 June 2, 2015 Page 2 of 2 3. The surface location of PBU S-44A will be located within State of Alaska lease ADL- 028257. The top of the productive interval and total depth of the well lie within State of Alaska lease ADL-028258. 4. PBU S-44A will be drilled to a structurally advantageous location to access an unswept portion of the Aurora Oil Pool reservoir that cannot be efficiently produced from existing wells. CONCLUSIONS: 1. An administrative waiver of the well spacing provisions of Rule 1 of Conservation Order No. 457B-Corrected is necessary to allow drilling, completion, and production of the PBU S-44A development oil well within the Aurora Oil Pool at a location that will maximize resource recovery. 2. PBU S-44A will recover reserves in the Aurora Oil Pool that are not accessible to other existing wells. NOW THEREFORE IT IS ORDERED: BP's application for an order granting an administrative waiver of the well spacing provisions of Rule 1 of CO 457B-Corrected to allow drilling, completion, and production of BP's PBU S-44A development oil well within the Aurora Oil Pool is hereby approved provided BP complies with the terms of all lease agreements, Alaska law, and all other legal requirem-. • .0,ott.„4Azi DONE at Anchorage, Alaska and dated June 2, 2015. if i Cathy ).

From: Lundgren, Carl E [mailto:Carl.Lundgren(abp.com] Sent: Monday, February 23, 2015 11:11 AM To: Davies, Stephen F (DOA) Subject: PBU S-44A (PTD #215=027) Hi, Steve - I'm following up on our discussion last week regarding the Aurora S-44A development well and the spacing requirements with the Aurora Oil Pool Rules(CO 457B-Corrected). The proposed horizontal well will be drilled in an irregular pattern east of the S100 producer and north of 5101 injector. Based on the center point of the well, the S44A development well will conform to the 40 acre spacing requirements by drainage area definition (see attached figure below). Relative to a vertical well, a horizontal well increases reservoir contact and enhances well productivity by drilling parallel to the formation of interest.The drainage area for the horizontal well has an ellipsoidal shape that extends along the horizontal well. As indicated in the figure,the estimated 40 acres drainage area of the S-44A well is represented by the 5100 polygon (black color) and S44 polygon (red color); both 40 acres drainage areas do not intercept each other and therefore, the wells are expected to have a drainage area greater than 40 acres. Considering the effective mid-perforation for both producer wells as the center of the drainage area, the distance between both wells is 2295 ft. which is greater than a typical 40 acres drainage area limit for two vertical wells (1490 ft.). Please give me a call if you have additional questions. Best Regards, Carl Carl Lundgren 3 • GPB West Satellites Team Leader • BP Alaska Phone:907-564-4334 ..-_. ". i ate.1 • - . qy `.. Hae{ .

From: Lundgren, Carl E [mailto:Carl.Lundgren@ bp.com] Sent: Monday, February 23, 2015 11:11 AM To: Davies, Stephen F (DOA) Subject: PBU S-44A (PTD #215=027) Hi, Steve - I'm following up on our discussion last week regarding the Aurora S-44A development well and the spacing requirements with the Aurora Oil Pool Rules(CO 457B-Corrected). The proposed horizontal well will be drilled in an irregular pattern east of the S100 producer and north of S101 injector. Based on the center point of the well, the S44A development well will conform to the 40 acre spacing requirements by drainage area definition (see attached figure below). Relative to a vertical well, a horizontal well increases reservoir contact and enhances well productivity by drilling parallel to the formation of interest.The drainage area for the horizontal well has an ellipsoidal shape that extends along the horizontal well. As indicated in the figure,the estimated 40 acres drainage area of the S-44A well is represented by the S100 polygon (black color) and S44 polygon (red color); both 40 acres drainage areas do not intercept each other and therefore,the wells are expected to have a drainage area greater than 40 acres. Considering the effective mid-perforation for both producer wells as the center of the drainage area, the distance between both wells is 2295 ft. which is greater than a typical 40 acres drainage area limit for two vertical wells(1490 ft.). Please give me a call if you have additional questions. Best Regards, Carl Carl Lundgren 3 GPB West Satellites Team Leader II • BP Alaska Phone:907-564-4334 _. ::.0.
