Thanks, David Minge Drilling Engineer West End Rotary Office:(907)564-4061 Cell :(907)250-2917 David.Minge@bp.com 2 • f From: Minge, David Sent: Thursday, July 09, 2015 7:03 AM To: 'jim.regg@alaska.gov' Cc: Allen, Kenneth W; Schneider, Kenneth J; AK, D&C Rotary Operation Superintendent; AK, D&C Rig 272 Well Site Leader Subject: Request for Variance: Drill Production Hole without FIT Jim, Parker 272 is currently on well L1-23,a Lisburne producer(PTD Number: 215-060).This weekend, 7" intermediate liner was set and successfully cemented with no losses, plug bump on bbls,and lift pressure within 20%of modelled. Cement was circulated off liner top. While drilling ahead in the Lisburne production hole, 18 ft into rathole,total returns were lost.Static loss rate was measured at 75—110 bph. For this reason,we were unable to perform an FIT. It is unlikely that loss rate will decrease to the point that an FIT will be possible. We are confident that we have a competent 7" shoe because of drilling ECDs prior to experiencing losses.With a 8.55 ppg drilling fluid,at 300 GPM,clean hole ECD is modelled at 9.097 ppg.There were no losses while drilling the first 18 ft of rathole. Required FIT for infinite kick tolerance is 8.9 ppg. Thus,we have subjected the shoe to pressures exceeding what is required for an infinite kick tolerance.We are requesting a variance to drill to TD of the production section without performing an FIT.

This grassroots well is a producer targeting the Lisburne formation. The planned well is a four string design using a 13-3/8" surface casing, 9-5/8" first intermediate casing, 7" second intermediate liner, and 4-1/2" production liner. The surface casing will be set in the SV4 shale. The first intermediate casing will be set at the top of the Sag River. The second intermediate liner will be set at the top Lisburne, and the production liner will be set will be set at the top Lisburne with the toe of the well extending into the Kavik. The production interval will be completed with a cementless liner, and the well will be acid stimulated post rig. The maximum anticipated surface pressure from the Lisburne with a full column of gas from TD to surface is 2,719 psi (assumes 7.8 ppg EMW most likely pore pressure and a 0.1 psi/ft gas gradient). The well will be drilled by Parker 272 using their 5,000 psi four preventer BOP stack (3 rams and an annular). The BOP rams will be tested to 4,000 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 Parker 272 and function test diverter. 2. Drill 16" surface hole to -5,324 ft MD. 3. Run 13-3/8"surface casing and cement to surface. 4. Nipple up BOPE and test rams_to 4,000 psi, annular to 3,500 psi. 5. Pressure test surface casing to 3,500 psi. Drill out the shoe and perform LOT. 6. Drill 12-1/4" intermediate hole to top of the Sag River at-12,060 ft MD. 7. Run 9-5/8" casing and cement to 500 ft MD below surface casing shoe (TOC at -5,824 ft MD). Pressure test casing to 4,000 psi. 8. Drill out of intermediate shoe and perform FIT. 9. Drill 8-1/2" hole to top of the Lisburne at-12,741 ft MD. 10. Run 7" casing and cement to TOL (TOC at-11,910 ft MD). 11. Pressure test casing to 4,000 psi. Drill out of intermediate shoe and perform FIT. 12. Drill 6-1/8" horizontal production hole through Lisburne to TD at-15,368 ft MD. 13. Run a 4-1/2" solid cementless swell packer liner. 14. Pressure test liner top packer to 4,000 psi. 15. Run 4-1/2" chrome completion tubing. Sting into liner tieback sleeve and set production packer. 16. Pressure test the tubing and the inner annulus to 4,000 psi each. 17. Rig down and move off the well.

L1-23 PTD Page 12 3/19/2015 L1-23 Variance Request 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 5 bbls has occurred. • The well will be monitored for flow when the pumps are off at each connection. • The planned 8.7-9.4 ppg fluid will provide over balance to formation fluid. • L1-23 Drilling Critical Issts POST THIS NOTICE IN THE DOGHOUSE I. Well Control / Reservoir Pressures: A. Intermediate Hole 1: The UG4 is expected to be a 9.3 ppg EMW. The CM1, CM2 and CM3 are expected to be a 10.2 ppg EMW. Formation pressures will be controlled with a 9.6 — 9.8 ppg mud to drill to within 200' MD of the CM3. At this point, there will be a weight up to 10.4— 11.0 ppg to drill the , rest of the interval to TD. B. Intermediate Hole 2: The Ivishak is expected to be at a 7.8 ppg EMW. Reservoir pressures will be, controlled with a 10.2— 10.7 ppg mud needed to drill the Kavik. C. Production Hole: The Lisburne is expected to be at a 7.8 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: There are no expected fault crossings in the first intermediate hole. However, breathing has been known to occur in the Colville on other Drill Sites in Prudhoe Bay as a result of high ECD's. B. Intermediate Hole 2: There are no expected fault crossings in the second intermediate hole. However, the lvishak will be drilled with a high mud weight/pore pressure differential which increases the likelihood of lost circulation. C. Production Hole: There are 5 expected fault crossings in the production hole. Past wells have experienced severe lost circulation and well bore breathing in the Lisburne. III.
