Item la. 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. Item 4b. TPI(Top of Producing Interval). Item 8: The Kelly Bushing and Ground Level elevation in feet above mean sea level. Use same as reference for depth measurements given in other spaces on this form and in any attachments. Item 13: The API number reported to AOGCC must be 14 digits(ex: 50-029-20123-00-00). Item 20: Report true vertical thickness of permafrost in Box 20 Provide MD and ND for the top and base of permafrost in Box 28. Item 23: Attached supplemental records for this well should show the details of any multiple stage cementing and the location of the cementing tool Item 24: If this well is completed for separate production from more than one interval(multiple completion),so state in item 1,and in item 23 show the producing intervals for only the interval reported in item 26. (Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval). Item 27: Method of Operation' Flowing,Gas Lift,Rod Pump, Hydraulic Pump,Submersible,Water Injection,Gas Injection,Shut-In,or Other(explain).

In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

Well Name: H-19C Well Type: Producer Current Status: Oil Producer Shut-In Request: P&A-Well Prep f/Rotary Sidetrack CMIT-TxIA Failed to 2500 psi (3/4/14) MIT-OA passed to 2000 psi (3/4/14) Well History: H-19 was originally drilled in 1983 as a Z2 producer. The well was completed with 7" x 5- 1/2" tubing and a 7" liner. The well had a RWO in 1987 to remove the 7" x 5-1/2" tubing and straddle pack assembly and replace it with a 5-1/2" tubing string w/5 gas lift mandrels. H-19 produced until it was SI for high GOR. Due to the bottom hole location being close to a series of faults, the likelihood of a successful gas shut off was low. So, H-19 was plugged back and prepared for sidetracking to the H-19A Z2 location in August 1997. Severe lost circulation during the CTD resulted in suspension of H-19A, and the well was plugged back to 100' above the whipstock @ 10,805' MD. The well was then coil sidetracked to the H-19B location in July 1998 and completed with a 2-7/8" liner. H-19B initial production rates came in -2500 bopd, but quickly fell to -1000 bopd. Gas production remained constant until a step change in 2004 when gas rate increased to over 40MMscf/d. The well was shut-in from 2006-2007 for high GOR. The well was then POP'd and cycled for over a year. Reason for P&A/RST: An organoseal job to s/o gas was performed, and during the post-squeezecrete milling job on 1/13, CT inadvertently sidetracked the liner at 11,017' MD. Due to the hole in the liner, the well has no value to base management, so it has remained SI. The well was secured with a WRP on 03/04/2013 in preparation for pre-rig integrity screening, and the WRP was left downhole as it will likely be utilized during the P&A.

Lost Circulation A. There are many instances of instability and losses thru the Kingak for wells at H-pad. Monitor drilling parameter to identify instability ensure ECDs are minimized with good hole cleaning practices and ECD management to reduce the likelihood of inducing fractures. B. Almost all Sag River wells have experienced lost circulation in the Production Hole section, and many H-Pad offset wells have had high rates of losses. Ill. Faults • Fault 1 is intersected in the Kingak formation at —8,053' MD with —10-20' of through. There is a low risk of lost circulation however there is an increased chance of wellbore instability to the wellbores orientation to the fault. Watch for signs of instability prior to crossing the fault. • Fault 3 is intersected in the Ivishak at —10,005' MD. It has a medium risk of lost circulation and a large throw of 50-70'. The Drill Ahead LCM pill should be prepaired prior to crossing. • Fault 4 is intersected in the Shublik at 10,750' MD and also has a medium risk of lost circulation. Its throw is 35-45' however if it is substantially less the DLS in the revert may need to be increased in order to not exit the Sag River. • Fault 5 is to be intersected in the Sag River at 11,578' and has a surprisingly low chance of lost circulation. It's throw is estimated to be 5-15' which could possibly fault into Shublik. IV.

Doyon 25 Close Approach Analysis We have examined the potential intersections of the subject well with all other potentially conflicting wells, according to the BPA Directional Survey handbook (BPA-D-004) dated 09/99. 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 hundred feet with an increment of one hundred feet for every one thousand feet of measured depth in the subject well. 2. Wells are analyzed using the Compass Anti-collision module (BP Company setup) with major risk safety factors applied. 3. All depths are relative to the planned well profile. Survey Program: Please see BP survey program on the anti-collision summary Survey Interval Intermediate hole: 1 per stand - 93 ft"# - Production hole: 1 per stand - 93 ft* * (except where planned or as-drilled doglegs are 5°/100' DLS or more; then survey every -30 ft across the interval, or per client request) # if a gyro is run, interval should be reduced if MWD surveys are clear of magnetic interference sooner than expected # Close Approach Analysis results: Under method (2), note: H-11 and H-22A fail the major risk. There are BP TCRW's in place to cover the exemption. There is potential to see magnetic interference from the planned KOP of 3300'md to±3800'md. A gyro single shot is planned to be run until good MWD can be attained. All data documenting these procedures is available for inspection at the Drilling & Measurements Drilling Engineering Center(DEC). Close Approach Drilling Aids to be provided: A drilling map and traveling cylinder plot will be provided.

If you will notice in the AC report, the wells H-11 and H-22A are labeled as"Pass—Minor 1/200".These wells were first classified as failing major risk. We then take steps to eliminate any HSE risk associated with colliding with these wells. In the case of H-11, it is an inoperable well that has been packed with killweight fluid and a deep set plug placed above the possible collision point. H-22A has a plug set in the production liner above the possible collision point and will be shut in at surface.
