Contact: Hartley, Josephine Maria Email: Josephine.Harfley@bp.com Printed Name: Joe Lastuf Title: Drilling Technologist Signature: Phone: +1 907 564 4091 Date: b 2 I INSTRUCTIONS General: This form is designed for submitting a complete and correct well completion report and log on all types of lands and leases in Alaska. Submit a well schematic diagram with each 10-407 well completion report and 10-404 well sundry report when the downhole well design is changed. All laboratory analytical reports regarding samples or tests from a well must be submitted to the AOGCC, no matter when the analyses are conducted. Item 1 a. 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 1 b. Well Class Service wells: Gas Injection, Water Injection, Water -Alternating -Gas Injection, Salt Water Disp, Water Supply for Injection, Observation or Other. Item 4b. TPI (Top of Producing Interval). Item 9. The Kelly Bushing and Ground Level elevations 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 15. 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 TVD for the top and base of permafrost in Box 29. Item 22. Review the reporting requirements of 20 AAC 25.071 and, pursuant to AS 31.05.030, submit all electronic data and printed logs within 90 days of completion, suspension, or abandonment, whichever occurs first. Item 23. Attached supplemental records 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). Item 28. Provide a listing of intervals cored and the corresponding formations, and a brief description in this box. Submit detailed description and analytical laboratory information required by 20 AAC 25.071. Item 30. Provide a listing of intervals tested and the corresponding formation, and a brief summary in this box. Submit detailed test and analytical laboratory information required by 20 AAC 25.071. Item 31. Pursuant to 20 AAC 25.070, attach to this form: well schematic diagram, summary of daily well operations, directional or inclination survey, and other tests as required including, but not limited to: core analysis, paleontological report, production or well test results.

This sidetrack targets a 70' oil column that has been logged in the current 14-29 well above the current perfs in that well. The 14-29 production section is inaccessible due to multiple fish lost in the wellbore. Three fishing attempts — 2 with coil and 1 rotary were unsuccessful. A rotary sidetrack was decided on to access the stranded attic oil. 14-28B will be an upper Zone 4B horizontal producer with offtake points deeper in the reservoir at the toe and heel section of the sidetrack, along with the ability to replace the 14-29 Zone 4 perfs if needed in the future. The well will have a single large undulation with one invert in the heel and a long flat revert to a turn down at the toe of the well. The planned well is a two string design using 7" intermediate liner, and a 4-1/2" production liner. The kick-off point will be in the SV2 formation. The intermediate liner will be set at the top of the Sag River, and the production interval will be completed with a cemented liner and perforated. The maximum anticipated surface pressure from the TCGL with a full column of gas from TD to surface is 2,452 psi (assumes 7.22 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 273 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams and annular will be tested to 3,500 psi. A detailed operations summary is included with the permit application. If there are any questions concerning information on 14-28B, please do not hesitate to use the contact information below.

Anti -Collision: / All offset wells pass BP Anti -collision Scan Criteria, however, multiple wells have been minor risked to J mitigate HSE risk.

These three wellbores (14-05A, 14-10, and 14-11 B) will have a gyro run pre-ng,in an attempt to clear up the anti -collision major risk failure. If the major risk A/C scan still fails after the gyros have been run, then all three wells will havef a tubng tail plug set and be shut in while drilling the intermediate interval. 14-29 has also been minor risked to mitigate HSE risk and will be shut-in while drilling the production interval Offset well ownership information All offset wells identified within 200 ft of the proposed wellbore are operated by BP. 14-28B PTD 5 1/13/2016 Loepp. Victoria T (DOA) From: Smith, James <James.Smith7@bp.com> Sent: Monday, January 25, 2016 9:15 AM To: Loepp, Victoria T (DOA) Subject: RE: PBU 14-28B(PTD 216-014) Anti -collision Victoria, As it currently stands, these 3 wellbores fail BP's Major Risk criteria and will have to be Minor Risked by setting a tubing tail plug in each and shutting them in. The hope is that by running a gyro in each of these wells it will reduce the uncertainty and these wells will then pass the major risk criteria. Th�jts will allow us to not have to set the plug and shut these wells in.

Production Hole: The Ivishak is expected to be at a 7.22 ppg EMW. Reservoir pressures will be controlled by using 8.5 — 9.0 ppg water based mud. II. Lost Circulation/Breathing A. Intermediate Hole 1: Breathing and/or lost circulation associated with excessive circulating pressures should be considered a possibility on this well. A fault crossing in the CM1 may increase the possibility of these events. B. Production Hole: There is 1 expected fault crossing in the production hole which is considered to have a low potential for lost circulation. Past wells on DS -14 have experienced severe lost circulation. III.

The hope is that by running a gyro in each of these wells it will reduce the uncertainty and these wells will then pass the major risk criteria. This will allow us to not have to set the plug and shut these wells in. Please let me know if you have any further questions.
