The sundry has the"Mechanical Integrity Test"check box ticked under the"conditions of approval: Notify Commission so that a representative may witness", but does not have the post initial injection MIT required box checked. I just want to clarify that the well will not require an additional MIT outside of the normal test cycle which was last tested on 10/18/2015 and was witnessed by Jeff Jones. If I'm interpreting the sundry incorrectly, and the well will need an MIT before being placed on MI injection please let me know at your convenience.

(BPXA),operator of the Prudhoe Bay Unit(PBU),on behalf of itself and the PBU Working Interest Owners, requests change of L-215 Well Status under Area Injection Order No. 26A(AIO 26A)to allow for the injection of enriched hydrocarbon gas into injection well L-215 (PTD# 205-127). AIO 26A states that all Orion service wells drilled prior to 5/1/2006 were reviewed and found suitable for EOR via enriched hydrocarbon gas injection. It was confirmed via phone conversation with Dave Roby(AOGCC Sr. Petroleum Engineer)on 1/18/17 that no further Area of Review is necessary as part of the 10-403 for L-215, since one was completed as part of AIO 26A. The attached 10-403 application seeks the reclassification of service well L-215 from PWI to WAG status based on AIO 26A and the verbal confirmation of compliance referenced above.All necessary integrity verifications will be performed per AOGCC and BP internal policy prior to commencing MI gas injection.

Drilling Engineer: John Rose, 564-5271 INSTRUCTIONS GeNeaAL: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. ITEM 1a: Classification of Service Wells: Gas Injection, Water Injection, Water-Alternating-Gas Injection, Salt Water Disposal, Water Supply for Injection, Observation, or Other. Multiple completion is defined as a well producing from more than one pool with production from each pool completely segregated. Each segregated pool is a completion. IreM 4b: TPI (Top of Producing Interval). IreM 8: The Keliy Bushing elevation in feet above mean low low water. Use same as reference for depth measurements given in other spaces on this form and in any attachments. IreM 13: The API number reported to AOGCC must be 14 digits (ex: 50-029-20123-00-00). IreM 20: True vertical thickness. IreM 22: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool.

Well Control Well control equipment consisting of 5,000 psi working pressure pipe rams (2), blind/shear rams, and annular preventer will be installed and are capable of handling the maximum potential surface pressures. Based upon calculations below, BOP equipment will be tested to 4,000 psi. Due to test pressures not exceeding , S,000psi it will not be necessary to have two sets of pipe rams installed at all times.

The Schrader in the Polygon 1A fault block is expected to be normal pressured at 8.6-8.7 ppg EMW. ~ This pressure is estimated based on offset well pressures and material balance. 11. Hydrates and Shallow gas ~ A. Gas Hydrates are expected at L-Pad near the base of the permafrost as gas hydrates have been encountered on may L-Pad wells. Setting casing through the SV1 should keep hydrate exposure from extending past the surface hole. B. Recommended practices and precautions for drilling hydrates should be followed in the surface hole. Occasionally hydrates are encountered below the SVi . III. Lost Circulation/Breathing A. Lost circulation is not expected to be a problem with the L-Pad faults associated with this well. B. We do not expect breathing on this well. i IV. Kick Tolerance/Integrity Testing A. The 9 $/8" casing will be cemented to surface. B. The 7" casing will be cemented with 15.8 Ib/gal tail cement to a minimum of 500' MD above the Ma sand 6889' MD. C. The Kick Tolerance for the 8-3/4" holes are ~50 bbls with 9.3 ppg mud, 11.3 ppg LOT, and an 9.0 ppg i pore pressure. D. Integrity Testing -LOT to a minimum of 11.3 ppg EMW. V. Stuck Pipe A. We do not expect stuck pipe if the hole is kept adequately clean. VI. Hydrogen Sulfide L-Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. No measurable H2S is being produced from the formation at this time. However 10 ppm is measured regularly at L-Pad as a result of the use of Ivishak gas lift gas. All L-Pad gas lift wells will likely have H2S in this concentration. Note that all injection has been with produced water not seawater. H2S levels are expected to remain low until the waterflood matures. Recent H2S data from the pad is as follows: Adjacent producers at Surface: Adjacent producers at TD: L-201 5 ppm L-201 5 ppm L-106 5 ppm Max Recorded on L-Pad: L-107 20 pm VII. Faults A. Two faults will be crossed while drilling this well. No losses or wellbore instability issues are expected to be associated with these faults. Details are listed below for reference: Fault 1 (SV6): 1045' MD 1029' TVD 950' TVDss Throw: 35' W Fault 2 (Ugnu UG4 in P61) 4810' MD 2944' TVD 2865' TVDss Throw: 110' W CONSULT THE L-PAD DATA SHEET AND THE WELL PLAN FOR ADDITIONAL INFORMATION L-2151 Well Plan Page 6 • • L-215i Drill and Complete Procedure Summary ***All pre-rig work should be charged off against the pre-drill AFE # ORD5M3566*** Pre-Rig Work: 1.

Method of analysis: 1. A list of wells to be analyzed is created in Compass by performing a global scan with an initial search radius of two thousand feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. WeAs are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. For problem wells that are plugged and abandoned or that can be shut in, risk-based safety factor may be used, with client notification. 3. All depths are relative to the planned well profile.
