The P-041_2 sidetrack will be a dual string exit from the existing 5- 1/2" liner. A 4-1/2" x 5-1/2" delta whipstock will be set at—11,517' MD. P-041_2 will kickoff from 5-1/2" liner drilling a horizontal well through Zone 4B: The well will be completed with 3-1/4" x 2-7/8" 13Cr-85 production liner, cemented and perforated post rig. Rig Work (scheduled to begin November 10, 2017) 1. MIRU and test BOPE 250 psi low and 3500 psi high (MASP 2,371 psi). 2. Mill 3.80" window and 10' of rathole. 3.

Hole Size: • 4.25" from 11,520' MD to 13,570' MD Liner Program: • 2-7/8" 6.4# 13Cr-85, STL Solid from 11920' MD to—13,570 MD • 3-1/4" 6.2# 13Cr-85, STL Solid from 11,260' MD to—11,920 MD • 19.4 bbls of 15.3 ppg cement will be used to cement the liner in place. (TOC at 11,720' MD) • The primary barrier for this operation: minimum EMW of 8.4 ppg (provides 636 psi overbalance) . • A cross over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams, and the CT packoff will be pressure tested to 250 psi low and 3500 psi high. • The annular preventer will be tested to 250 psi low and 3500 psi high. Directional: • See attached directional plan. Maximum planned hole angle is 98°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property line: 10,450' • Distance to nearest well within pool: 800' Logging: • MWD directional, gamma ray, and resistivity. Perforating: • Perforating will be completed post rig. Anti -Collision Failures: • P-041_2 passes BP Anti -Collision criteria Hazards: • P-Pad is considered a H2S pad • Most recent H2S level on P-Pad was at P-27 with 21 ppm recorded on 3/16/2017 • Lost circulation potential in P-041_2 is medium. - Reservoir Pressure: • The reservoir pressure on P-041_2 is expected to be 3264 psi at 8930' TVDss. (7.03 ppg EMW) • Maximum expected surface pressure with a full column of gas (0.10 psi/ft) to surface is 2371 psi. • An EMW of 8.4 ppg will provide a 636 psi overbalance to the reservoir. Managed Pressure Drilling: • MPD techniques may be used to improve hole stability. • An automatic choke will maintain a target ECD at the window for the duration of drilling to improve hole stability. • A pressure schedule will be used for tripping In/Out of the hole. The purpose of the pressure schedule for tripping is to maintain the same bottom hole pressure at the window by applying surface pressure via the choke. • At all times, drilling fluid weight will be greater than equivalent pore pressure. MPD is only being - used for hole stability. Jacob Leemhuis CC: Well File CTD Engineer Joe Lastufka Jacob.Leemhuis@bp.com 907-564-4989 TREE = 4-1/16' FLS C1W WELLHEAD= C1W ACTUATOR= BAKER INITIAL KB.
