To better understand how to economically manage this risk over the long term, we are trialing an H2S inhibitor treatment known as a Sodium Nitrite Squeeze. Over the past year, several high-H2S wells in GPB were monitored. 04-38A was selected for the Nitrite Squeeze trial due to its elevated and consistent H2S levels in addition to its good on-time. Should this inexpensive treatment prove effective at reducing H2S levels in individual producers, GPB will have a potential option for safely producing high H2S wells in the event that they continue to increase or if individual facilities reach emission limits in the future. Continued monitoring of H2S levels following this treatment is critical to evaluating the effectiveness of the Nitrite Squeeze, these details are outlined in the Pumping and Monitoring Requirements tables. Proposed Program: 1. Perform TIFL 2. Pump Nitrite Squeeze (See Pumping Details Table) 3. Monitor Results (See Monitoring Details Table) BP Exploration (Alaska), Inc. P.O.

Planned operations: The proposed 04-38A CTD sidetrack will be an approximately 1500' Zone 2A/2B producer drilled with the Nabors CDR2 rig on or around September ist, 2017. A 3-1/2" whipstock will be set pre -rig with a -line. The rig will move in, kill the well and mill a 2.80" dual string window (3-1/2" x 5-1/2"), -10' long. The well kicks -off in Zone 4 and will be drilled through the conglomerates and target reserves in Zone 2A/2B. The proposed sidetrack is a -1500' horizontal Ivishak producer to be completed with a 2-3/8" 13Cr solid liner, cemented in place and selectively perforated post rig. The liner cement job or liner top packer will isolate all parent perforations.* Post -Rig Work: 1. V: Tree work as necessary. 2. F: PT Liner lap 3. S: Set LGLVs. LTP set post rig 4.

Disposal: • All Class I & II non -hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 must go to GNI. Hole Size: • 3.25" for production hole section from 8625' MD to 10,171' MD. Liner Program: • 2-3/8", 4.7 Ib/ft, H511, 13Cr 8575' MD - 10,171' MD (TD) • A planned 13 bbls of 15.3 ppg cement will be used for liner cementing (TOC = TOL at -8575' MD). • The primary barrier for this operation: a minimum EMW of 8.4 ppg (489 psi over -balance). • A X -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 pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. Directional: • See attached directional plan. Maximum planned hole angle is 1050, inclination at kick off point is 100. . • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 46,970' • Distance to nearest well within pool - 1550' Logging: • MWD directional, Gamma Ray, and Resistivity will be run through the entire open hole section. Perforating: • Perforating planned Post -rig: -550' of perforations. 1.56", 60 deg random phasing, 6 spf, pert guns. Anti -Collision Failures: • None. All offset wells pass BP anti -collision scan criteria. • No wells were minor risked. Hazards: • DS 04 is an H2S pad. Latest H2S reading on the 04-38 was 36 ppm on 11/3/2016. • One fault crossings planned, but Lost circulation risk in 04-38A is considered to be LOW. o Fault is considered to be small and losses are not a significant issue in the area. Reservoir Pressure: • The reservoir pressure on 04-38A is expected to be 3,354 psi at 8,800' TVDSS (7.33 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,474 psi. • Amin EMW of 8.4 ppg for this well will provide 489 psi over -balance to the reservoir.
