On 5/14/18 slickline completed a gas lift change out and performed a passing MIT-T to 2431psi and CMIT-TxIA to 2357psi. The passing pressure test confirms that well barriers have successfully been restored. At this time the well is reclassified as Operable.

It currently has badly corroded tubing causing T x lA communication. It has also failed an NFT-IA, so is secured with a tubing tail plug and the well shut in. A workover will be performed changing the 4-1/2" L-80 production tubing to 4-1/2" chrome, using a stacker packer completion. After the workover, a whipstock will be set near TD in the production liner, and a coil tubing sidetrack drilled. The cement job on the sidetrack liner is planned to come up to 12,500' MD in the parent wellbore (Inclination 89.9 deg). Perforations in the parent well above this depth are intended to be preserved. Perforations below this depth are intended to be abandoned by the liner cement job. The plan is to leave 520' of open perforations in the parent wellbore above the cement top depth while abandoning 410' below the cement top. The inclination of the top perforation in the parent well is 59 deg. One factor that should be considered is that predicting the cement top using current coil tubing technology is not exact. The cement job is designed so that the cement top is at a relative "high" in the parent well. However annular spaces in this type of completion are very small and a slight difference in cement volumes significantly affects the height of the cement top. There is a small possibility that some or all of the perForations above 12,500' will be covered by cement. A sketch showing the well geometry is attached to give clarity to the situation. As it is desired to continue production from the parent wellbore perforations, we have as a contingency plan, the ability to reperforate the existing perforations to re-establish communication to them. Extended Reach Discussion The TD requested in the permit to drill is 17,675'. This is considerably past what our models predict is achievable with coil tubing in a conventional sliding mode. Our models predict that it is only possible to reach a depth of 16,475' using our standard CTD techniques. BP's intention on this well is to conduct a test of a new down hole drilling tractor tool to assist weight on bit while drilling and for running liner 1,200' past what our models predict is possible. This is new technology which could offer opportunities for coil tubing to achieve extended reach targets for future sidetrack well candidates. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will~tested to 250 psi and 2500 psi. ~ Directional • See attached directional plan. Max. planned hole angle is 91.6 deg. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property - 4,515 ft. • Distance to nearest well within pool - 7$0 ft. (X-33) Logging • MWD directional, Gamma Ray, Resistivity will be run over all of the open hole section. • A cased hole MCNL/GR/CCL log will be run. Hazards • The maximum recorded H2S level on X Pad is 150 ppm. • The maximum recorded H2S level on X-30 was 10 ppm on 4/11/2005. • Lost circulation risk is average. • Leak at SSSV - monitor IA throughout job. Double valve the IA for MIRU. Rerun dummy valve in upper GLM prior to beginning sidetrack. Reservoir Pressure • The max reservoir pressure was measured at 3400 psi at 8800'ss in June 2005. (7.5 ppg EMW). • Max. surface pressure with gas (0.10 psi/ft) to surface is 2520 psi. °w~°-- Greg Sarber CTD Engineer CC: Well File Sondra Stewman/Terrie Hubble ~ " TREE- CIW 4 WELLh#AD = FMC ACTWiTOR= BAKER KB E1EV = 70 01' BF ELEV = 3900' KOP- 1fiB6' ___. . .... __ . f~x Angle = ____ - - --- - 30 ~ 1241 T patum MD = 11522' Qalum TV ~= 8800' SS 10-3l4" CSG. 45.5N, L-80, 10 = 9 953" 3277' ~ cr,e,-, ~.,~ ; 9c N ~.

Datum Drilling Measured From Elevation of Kelly Bushing Elevation of Derrick Floor Elevation of Ground Level Casing Depth Other Services Line 1 (1) All depths are Measured Depths (MD) unless otherwise noted. 2-n~'-O~ ~ ~ 1p~' . ~ (2) All depths are Bit Depths unless otherwise noted. (3) Al1 True Vertical Depths (TVDSS) are SubSea corrected. (4) All Formation Evaluation data is realtime data. (5) Baker Hughes INTEQ utilized CoilTrak downhole tools and the Advantage surface system to log this well.. (6) Tools ran in the string included Casing Collar Locator, an Electrical Disconnect and Circulating Sub, a Drilling Performance Sub (Inner and Outer pownhole Pressure, Vibration and Downhole Weight on Bit), a Directional and Gamma Sub, and a Hydraulic Orienting Sub with a Near Bit Inclination Sensor. (7) Data presented here is final and has been depth adjusted to a PDC (Primary Depth Control) log from well X-30APB1 dated 24 Sep 2007 above the KOP of 13450 feet MD per poug Dortch with BP Exploration (Alaska), Inc. (8) Tie into RA Taq in X-30A at 12889 feet MD (8973 feet TVDSS). (9) The sidetrack was drilled off a permanent whipstock from X-30 set at 12876 feet MD (8972 feet TVDSS) through a 5 1/2 inch casing. Top of window 12880 ft.MD (8973 ft.TVDSS) Bottom of window 12892 ft.MD (8974 ft.TVDSS) (10) Baker Hughes INTEQ runs 1 and 2 were used to mill up fast plugs and set a permanent whipstock. (11) Baker Hughes INTEQ runs 6 and 7 were used to set and sidetrack off of an aluminum billet. (12) The interval from 13448 feet to 13470 feet MD (8970 feet to 8969 feet TVDSS) was time drilled off of an aluminum billet. (13) The interval from 13558 feet to 13590 feet MD (8973 feet to 8972 feet TVDSS) was not logged due to sensor to bit offset at well TD. (12) The resisitivity interval from 13448 feet to 13470 feet MD (8970 feet to 8970 feet TVDSS) was logqed in run 8, 14 hours after dilling.
