Slickline ran a caliper on 2/19/17 and found heavy wall penetrations at 7,717' which is suspected to be a hole. On 8/31/17 Eline set a tubing patch from 7707'-7737'and DHD performed a passing MIT-IA to 2,681psi on 9/1/17. The passing test confirms two competent barriers in the wellbore. The well is reclassified as Operable. Please mind fluid pack annuli when bringing the well online. Please reply with any questions, Joshua Stephens 2017.

As the attached AOGCC BOPE Test Report shows the test lasted 3 hours and there were no failures. The lower pipe rams were not tested at this time due to the length of the crossovers to the tuging hanger. These rams were tested by toolpusher Bob Mize when the tubing was laid down. The testing went'very well considering this is a new rig with new crews. The rig was clean and all equipment appeared to be properly rigged up. The location was clean and all extra equipment was properly stored. Summary: I witnessed the inital BOPE test on Nabors Rig 7ES drilling BPXs E- 04A well.

If Class I wastes are generated, they will be taken to Pad 3 disposal site. Bottom hole pressure is 3,323 psi at 8,360' TVDss (estimated) Maximum shut-in casing pressure is 2,487 psi (assumes 0.1 psi/ft gas gradient to surface). Drilling Discussion Well Ob|ective This sidetrack targets Zone 2 sands 12' above the HOT. The well is designed to drill approximately 250' of horizontal section at 8,988' TVDss. The well is then drilled into the HOT for approximately 900'. This portion of the well will be used for future sidetracks that require an open junction. The idea behind putting the future open junction access in the HOT is because the pores between the sand grains is so occluded with tar that gas would not be able to communicate with the junction that woukld be left open between the E-04A liner and the future sidetrack well. After drilling 900' in the HOT, the well is inverted out of the HOT into a second fault block, again 13' above the HOT at 8,987' TVDss. This second target is approximately 800' long. Anticipated average initial rate is 2,300 BOPD. Expected incremental recovery is 1.258 MMBO. Drilling Objective The objective is to cut and pull the existing 5 V2" completion tubing @ 8,365 ft, mill window via whipstock in the 9 5/8" casing @ 8,350' MD, directionally drill 8 1/2" hole through the Kingak shale to TD + 9,670' (10' into the Sag River); run, cement and test 7" liner. Directionally drill 6" hole out of the 7" shoe to horizontal at + 10,500' MD. Run DPC logs. Geosteer through Z2 sands ( two targets) to TD at + 12,737'. The well will be completed as a Zone 2 producer with a 4 V2", L-80, 12.6# solid liner x 4 lA" 12.6#, L-80, tbg with (6) GLM's and WOA tailpipe assy. The GLM's will be run with depths determined after log evaluation. Perforation intervals will be determined after final log evaluations. DRILLING HAZARDS AND CONTINGENCIES Always have two levels of tested isolation before NUfND. SURFACE CLOSE APPROACH WELL SHUT-INS One adjacent well will need to be shut in for the rig move. Adjacent well E-35 is spaced 33' South and will need to be shut-in prior to the rig move. Careful coordination with any ongoing pad or facility operations or activities will be initiated prior to commencing the rig move. DRILLING CLOSE APPROA~I-I WELL SHUT-INS No shut-ins identified on Sperry Sun directional well plans due to close approach requirements. PORE PRESSURE: Pore pressure in the Kingak Shale is expected to be 7.7 EMW. The Kingak section will be drilled using 10 ppg mud due to shale mechanical instability. The mud weight will provide sufficient overbalance to reservoir pressure and not too high of an overbalance to create lost circulation while drilling the shale. The pore pressure in the Sag River (7" liner shoe) is expected to be near 7.7 ppg EMW and the Sadlerochit is expected to be near 7.8 ppg EMW. 8.7 - 8.8 ppg mud will be used drilling out of the Sag River and through the Sadlerochit zones and will provide sufficient overbalance to the reservoir pressure.. HOLE PROBLEMS Six mapped faults will be present while drilling this hole which could cause lost circulation and possible additional bit steering. The upthrown and downthrown faults could cause bits to track in the throw trend. Adequate lost circulation material will be on the location to handle any possible loss problem. The Kingak shale will be drilled with 10 ppg mud from 32° to 46° inclination. Casing Shoe Kick Tolerance The smallest kick tolerance for the casing shoes is calculated as infinite of influx assuming a swabbed gas influx at the bottom of the Sag River along the planned directional path. Based on 8.7 ppg MW (TSAG 9,660' MD & 8,653' TVD 8.0 ppg maximum reservoir pore pressure), and min. frac at the window 10.0 ppg . The casing shoe will withstand complete (gas) evacuation to surface based on predicted pressures. Pre-Rig Operations: 1. Pressure test the 9 5/8" packoff. If the 9 5/8" packoff tests, back out and check each LDS (check one at a time). If the packoff does not test, carefully cycle each LDS (one at a time). 2.
