On 5/5/18 Slickline completed resetting the screen orifice gas lift valve and the well passed as subsequent TIFL on 5/6/2018. The passing TIFL confirms that the primary well barrier has successfully been restored. At this time the well is reclassified as Operable.

The permit to redrill does nOt exempt you from obtaining additional permits required by law from other governmental agencies, and does not'authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOpE) must be tested in accOrdance with 20 AAC 25 035. Sufficient notice (approximately 24 hours), must be given to allow a representative of the Commission to witness a test of BOPE installed prior to drilling new hole. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. Sincerely, J. M.

This sidetrack will be conducted in two phases. Phase 1: P&A existing perforations, mill window off cement plug: Planned for Nov. 25-26, 2000. · A Mechanical Integrity Test will be performed. · A 2.8" drift and jewelry log will be run. · Service coil will be used to cement the existing perforations and pressure test. · Service coil will be used to mill the window. Phase 2: Drill and Complete sidetrack: Planned for Dec 2, 2000. Drilling coil will be used to drill and complete the directional hole as per attached plan. Mud Program: · Phase l& 2: Seawater · Phase 3: FIo-Pro (8.5 - 8.7 ppg) Disposal: · No annular injection on this well. · All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. · All Class I wastes will go to Pad 3 for disposal. Casing Program: · 2 3/8", 4.6#, L-80, FL4S liner will be run from TD to approx. 9,480' MD (8555'tvdss, TOL) and cemented with approx. 10 bbls. To bring the top of cement to approx. 9,480'md (TOC). The liner will be pressure tested to 2200 psi and perforated with coiled tubing conveyed guns. Well Control: · BOP diagram is attached. · Pipe rams, blind rams and the CT pack off will be pressure tested to 400 psi and to 3500 psi. · The annular preventer will be tested to 400 psi and 2000 psi. Directional · See attached directional plan · Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging · A Gamma Ray log will be run over all of the open hole section. · A Memory CNL will be run in cased hole. Hazards ~/~, · No faults or lost circulation are expected. Res. pressure is normal. DS 15 is not an H2S Pad - last test 10/19/00 at 400ppm. Reservoir Pressure Res. pressure is approx. 3400psi @ 8800ss. Max. surface pressure with gas (0.1 psi/ft) to surface is 2520 psi. 4-41A Potential Drilling Hazards Post on Rig 1. Please perform pre-job Hazard ID and Safety meetings prior to every change in work scope during the operation. Also, if things don't look right shut-down the operation and discuss the situation before making the next operational move. SAFETY FIRST. 2. H2S is expected on this well. Last test 10/19/00 at 400ppm. 3. BHP is expected to be 3400psi (7.43ppg) @ 8800ss. 4. Maximum anticipated well head pressure w/full column of gas 2520psi. 5. Lost circulation risk is Iow with no anticipated faults in polygon. 6. The well is planned not to penetrate the Kavik, but there is a chance of accidentally penetrating the Kavik due to regional depth uncertainty. The Kavik could cause some drilling difficulties.
