Both an MIT-T& MIT-IA passed to 4000 psi on March 28,2016 confirming two competent barriers in the wellbore. The well was classified as Not Operable due to the unavailability of MI on R Pad. With MI on the pad,the well is now ready to be put on injection and is reclassified as Operable. An initial AOGCC MIT-IA is required once the well is placed on injection and thermally stable. Please mind fluid packed annuli when POI. Plan Forward: 1. Operations: Put on MI Injection 2. Fullbore: AOGCC MIT-IA to 4000 psi Please call with any questions or concerns.

R-44 is planned to be a multi-zone injector providing injection support into both the Sag River and Ivishak formations. R-44 is currently scheduled to be drilled by Parker.273 beginning —3/1/16. The planned well has 3 hole sections with 13-1/2" surface hole to an SV2 casing point with 10-3/4" casing, 9-7/8" intermediate hole to a TSGR• casing point with 7" casing, and 6-1/8" production hole to a Ivishak and Sag River horizontal target with a final 4-1/2" production liner. The maximum anticipated surface pressure from the Sag River with a full column of gas from intermediate TD to surface is-1402 psi (assuming the most likely PP of 5.0 ppg at TD). The maximum anticipated surface pressure from the Ivishak with a full column of gas from the deepest point in the production hole is • 1667 psi (assuming the most likely PP of 5.49 ppg in the Ivishak). Parker 273 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. �_ The plan for R-44 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 273 and function test the diverter. 3. MU 13-1/2" bent housing motor drilling assembly. Drill to a shale in the SV2 sands at—3580' MD. ' 4.

Well AOR info The parent completion on R-32 isolated above TSGR to the upper formations by the original cement job R-32Ai on the 9-5/8" production casing which was run to a depth of 11,674' MD. The 9-5/8" casing was cemented with 700 sx Class G lead cement followed by 400 sx Class G tail cement. No losses were noted during the job,the plug did not bump, but the floats held. Estimated TOC based on gauge hole is 2,818' MD. It was noted that 11 bbls of cement channeled back to surface. 9-5/8"casing was run to TD of 13,640' MD,and cemented with 512 bbls Class G lead followed by 41 bbls F-39 of Class G tail cement. The plug was bumped on this cement job and there was no reference to any fluid loss during displacement. Estimated TOC based on gauge hole is 3,734' MD; The F-43 well was isolated above TSGR to the upper formations by the original cement job on the 9-5/8" F-43 production casing which was run to a depth of 13,829' MD. The 9-5/8" casing was cemented with 499 bbls 13.2 ppg Class G lead cement followed by 51 bbls 15.8 ppg Class G tail cement. No losses were noted during the job.The TOC is expected to be at 3,969 MD assuming gauge hole. The F-30 well was isolated above TSGR to the upper formations by the original cement job on the 9-5/8" production casing which was run to a depth of 11,875' MD. The 9-5/8"casing was cemented with 1971 F-30 cuft 13.2 ppg Class G lead cement followed by 648 cuft 559 sx 15.8 ppg Class G tail cement. No losses were noted during the job,the plug bumped,and float held.The expected TOC is expected to be at 3,735' MD assuming gauge hole. The R-26A well was isolated above TSGR to the upper formations by the original cement job on the 9- R-26A 5/8"production casing which was run to a depth of 9,101' MD. The 9-5/8"casing was cemented with R-26B 281 bbls 13.2 ppg Class G lead cement followed by 41 bbls 15.8 ppg Class G tail cement. No losses were R-26BL1 noted during the job and the plug bumped.The expected TOC is at 3,328' MD assuming gauge hole. R- 26B and R-26BL1 were coil sidetracks out of the 7" liner that had slotted liner completions. The R-36 well was isolated above TSGR to the upper formations by the original cement job on the 7-5/8" production casing which was run to a depth of 9,824' MD. The 9-5/8"casing was cemented with 171 bbls 11 ppg lead cement followed by 57 bbls 15.8 ppg Class G tail cement.The casing packed off when staging the pumps up prior to cementing,and there were no returns to surface while displacing the R-36 cement.After displacing the cement the plugs were bumped and floats held.The Mud weight was reduced from a 9.5 ppg to 8.9 ppg before drilling out the float equipment and performing a FIT to 9.6 ppg EMW.The production hole was drilled to 10,162' MD, and then abandoned with a 29 bbl open hole cement plug due to it having no reserves.The expected TOC1)ehind the 7-5/8"casing is assumed to be at 3,863'MD if the annulus packed off above the TOC and gauge hole. The R-34 well was isolated above TSGR to the upper formations by the original cement job on the 9-5/8" production casing which was run to a depth of 13,781' MD. The 9-5/8" casing was supposed to be cemented with 302 bbls 11 ppg lead cement followed by 74 bbls 15.8 ppg Class G tail cement. No losses R-34 were noted during the job,the plug did not bumped,and float held. Notes in the well file indicate that the lead cement volume pumped was 160 bbls less than planned, and it was believed that the lead cement density was much higher than 11.0 ppg. If it is assumed that the report is correct and only 142 bbls of the lead cement was pumped then the TOC is expected to be at 9,909' MD. The R-35 well was isolated above TSGR to the upper formations by the original cement job on the 7-5/8" production casing which was run to a depth of 12,075' MD. The 7-5/8" casing was cemented with 475 sx R-35 (280)bbls 11 ppg lead cement followed by 57 bbls 15.8 ppg Class G tail cement. No losses were noted R-35A during the job,the plug did not bumped,and float held.The expected TOC is at 3,265' MD assuming gauge hole. R-35A is a recently drilled coil side track that kicked off out of the 7-5/8" production casing and ran a partially cemented 3-1/2 x 3-1/4 x 2-7/8" liner to 14,275' MD. R-44 PTD Page 4 10/28/2015 0 6 The R-10 well was isolated above the TSGR to the upper formations buy the cement job on the original 9-5/8" production casing which was run to a depth of 10,038' MD.The 9-5/8"casing was cemented in R-10 two stages. 1195 sx of 15.8 ppg G cement(244 bbls)was circulated thru the shoe on the first stage bringing cement up to 5,650 MD assuming gauge hole.The second stage was thru a DV collar at 2618' MD where 212 bbls of arctic pack and 140 sx(23 bbls)of AS 1 cement circulated into the 9-5/8"x 13- 3/8"annulus.There is no record of losses during the cement jobs, and all plugs bumped and floats held.

Close Approach Shut-in Wells: R-26B is a inaccessible 3-3/16" x 2-3/8" coil slotted liner that will be drilled by in R-44's production hole section. The well passes a minor risk value of 1:200 and will be SI at surface. Sub-Surface Pressure Management: R-26B -will be shut in 108 days before R-44 drills into the TSGR. This is to ensure the reservoir pressure is >2200 psi making certain the fracture gradient is at least 11.7 ppg EMW. R-32A-will be SI prior to drilling out of the 7" intermediate casing. This is to eliminate the possibility of R- 32A's injection fluid traveling thru a fault network and causing an active influx during production hole drilling. Offset well ownership information: All offset wells identified within 200 ft of the proposed wellbore are operated by BP.

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. After drilling past the larger rocks and wood sections, the flow paddle will be put back in the flow line (<1,000 ft). Procedures/Safeguards with paddle removed: • Fluid levels will be monitored in the pits for both gains and losses while drilling. Alarms will be set to indicate if gain or loss of more than 10 bbls has occurred. • The well will be monitored for flow when the pumps are off at each connection. • The planned 8.6 -9.4 ppg fluid will provide over balance to formation fluid. B. Due to the geometry of the production interval, it is requested to set the production packer —1,174ft MD above the top of the perforations. This is a variance from 20 AAC 25.412.

Surface Hole: No overpressure is expected in the surface hole and hydrates are not expected on R- Pad. B. Intermediate Hole: Normal PP to top UG4A. Cretaceous injection pressure to 9.1 ppg at top UG4A. PP to 9.65 ppg at top CM3. Sag River pore pressure is expected to be 5.0 ppg. C. Production Hole: The pore pressure in the Sag River production interval is anticipated to be under - pressured due to offset well production with limited injection support. Sag River PP is expected to be 5.0 ppg, while Ivishak PP is expected to be 5.49 ppg. The interval will be drilled with a substantial over balance utilizing an 8.5 ppg fluid. II. Lost Circulation/Breathing A. Surface Hole: Lost circulation is considered a low probably and is rare on R-Pad. B. Intermediate Hole: Breathing and/or lost circulation associated with excessive circulating pressures should be considered a possibility on this well. The Sag River has a lower than average pore pressure and fracture gradient in the area of R Pad. Due to the lower frac gradient, there is an increased risk of lost circulation during drilling, casing, and cementing the intermediate hole. C. Production Hole: R-Pad's Sag River has historically had less lost circulation then other parts of the field, but it is critical that losses be reduced to a manageable level before cementing the production liner. If lost circulation becomes a problem, follow the LCM decision tree provided in the drilling program. III.

Kingak Shale - Multiple fault crossings are expected in while drilling the production hole. This increases the probability of drilling out of zone into the highly unstable Kingak Shale leading to wellbore instability leading to stuck pipe. Heightened awareness is required while crossing faluts to identify if the Kingak has been drilled into. B. The planned wellpath may encounter a complex fault network at the fault 4 crossing. It is suspected that this area may be made up of multiple small faults and or grabens increasing the likely hood of instability and losses. VII. Anti-Collision Issues R-26B is a inaccessible 3-3/16" x 2-3/8" coil slotted liner that will be drilled by in R-44's production hole section.
