History and current status: 02-07A was drilled in 8/98, as a 2000' horizontal well completed with 1627' perfs in Z2A. In 2/01, a CIBP was set to shut in all but 397' of perfs closest to the heel. In 2/03 the CIBP was milled. In 7/03 a CIBP was set to shut in the entire lateral and perfs were added in Z2BI. Oil rate was added at a lower GOR. In 2009 the well was shut in with annular communication. In 2/11 it returned to service with a RWO, but gas rate was high. A down hole screen was run for solids control in 10/11 which knocked out some fluid rate, causing a jump in GOR. In 5/13 the screen was pulled to mill the CIBP and straddle Z2BI. In 6/13 Z2BI was straddled and the screen was rerun. In 8/13 the screen was pulled to test Z2A alone. It was still at an uncompetitive GOR. The well is currently a swing well, often shut in ,/ for high GOR. Proposed plan: 02-07B will exit from well 02-07A by the Nordic 1 Coiled Tubing Drilling rig on or around June 1, 2014. The 02-07B sidetrack will exit through the existing 4-1/2" liner and kick off in Zone 1, and target Zone 1B Reserves. The proposed sidetrack is a -2,010' horizontal Ivishak Zone 1B producer, which will access a -35 acre target south of DS-02. The lateral will be completed with a 3-1/2" X 3-1/4" X 2-7/8" L-80 liner which will be Fully cemented and perforated. This Sundry covers plugging the existing 02-07A perforations via the 02-07B liner cement job or a liner top packer set post rig with slick line if Liner lap test fails. (alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference. !k welt c !t ro/bc<r q/- f 1)C07,7, GD/Q /7 S'40 ye.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Gerald Murphy, at 659 -5102. Sincerely, Mehreen Vazir BPXA, Well Integrity Coordinator • • BP Exploration (Alaska) Inc.

DS 2-07A Permit to Drill 2 Maximum anticipated BHP: Maximum surface pressure: Planned completion fluid: 4218 psi @ 8195' TVDss(9.9 ppg EMW) 3432 psi @ 8800' TVDss(7.5 ppg EMW) 3398 psi @ 8195' TVDss - Put River 2520 psi @ 8800' TVDss - Zone 2B 8.5 ppg Seawater / diesel freeze protection Drilling Hazards/Continqencies DRILLING CLOSE APPROACH: · There are down hole close approach wells. H2S: · Drill Site 2 is not considered to be an H2S Drill Site. All H2S levels at DS 2 are less than 10 ppm. Crew H2S drills will be performed routinely along with the other require drills. INTERMEDIATE SECTION: · The well will sidetrack in the K shales; most of the Kingak is truncated by the LCU. The previous well DS 2-36 did not have any hole problems attributed to this section. · The Put River sand is hydrocarbon bearing with original reservoir pressure and possible high pressure shale stringers exist above the Put River. The estimate pore pressure in the Put River is 4218 psi or an EMW of 9.9 ppg. Drilling will be with sufficient mud weight to adequately suppress the pore pressure between casing points. · The kick tolerance for the 9-5/8" window would be an infinite influx assuming an influx at the TSag 7" casing point. This is a worst case scenario based on a 9.9 ppg pore pressure and a minimum fracture gradient of 12.0 ppg with a 10.0 ppg mud weight. PRODUCTION SECTION: · Loss circulation can be a problem on Drill Site 2. If losses do occur the lost circulation decision tree for non-productive zones will be followed until entering -- the target polygon and the productive zone decision tree thereafter. · The kick tolerance for the 7" shoe would be an infinite influx assuming an influx at the 12,581' TD. This is a worst case scenario based on a 8.6 ppg pore pressure and a minimum fracture gradient of 10.4 ppg with a 8.6 ppg mud weight. DS 2-07A Permit to Drill 3 Disposal No annular injection in this well. Cuttings Handling: Cuttings should be hauled to the ball mill at CC-2A. Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. In addition, haul all cuttings from drilling operations to CC-2A for disposal, except any metal cuttings which will be sent to the North Slope Borough. SUMMARY SIDETRACK PROCEDURES Pre-Riq Work · Unable to test the 9-5/8" x 4-1/2" / 3-1/2" until after the P&A due to a suspected tubing leak above the 9-5/8" production packer at 8188'. 1. Pull the 4 1/2" SSSV. Valve is set at 2213' MD. 2. Perforate the tubing at 9450' with 8' of shots at 4 spf each and 9727'(between the bottom blast joint at 9721' and the top of the packer at 9733'). Exact shot placement is extremely critical due to shooting the 12' between the blast joint and packer. * It may be more beneficial to cut the tubing at 9727' than perforate after the P&A of the bottom perforations. 3. The objective of the cement plug and abandon is to P&A the bottom perforations, allowing adequate time for the cement to set then P&A the straddled perforations by circulating through the tubing perforations at 9715' and 9450'. Rig up a CTU and P & A the bottom perforations. Stage 1: Pump 13 barrels of cement to fill the 7" liner from the bottom packer at 9733' to PBTD at 9934' plus squeeze away 5 barrels to the perforations. Stage 2: After waiting 4 hours circulate through the tubing perforationS; at 9727' pumping 17 - barrels of cement to fill the 7"x 3-1/2" annulus and 3-1/2" tubing plus squeeze away 5 barrels to the perforations. 4. Rig up slickline and drift the tubing to 2.625" documenting the top of cement. · Top of cement must be at a minimum of 9546' for AOGCC compliance, plan to leave TOC @ 9400' unless a squeeze is not possible then leave TOC @ 8200' at the highest. 5. Pressure test the cement plug and casing to 3000 psi for 30 min. · If the pressure test fails notify the Nabors 22E Drilling Engineer at 564-5486. 6. Cut the 4 1/2" L-80 tubing with a chemical cutter in the middle of the full joint of tubing below the bottom GLM(bottom GLM @ 8008'; estimated cut depth @ 8028'). 7. If not done previously, circulate the well with 8.5 seawater ensuring there is no trapped gas and the well is dead. 8. Freeze protect top 2200' MD with diesel. 9. Bleed tubing and annuli pressures to zero. DS 2-07A Permit to Drill 4 10. Test the 9-5/8" mandrel packoff to 5000 psi for 30 minutes. 11. Set BPV in the tubing hanger and test from below to 1000 psi. Secure well. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. Riq Operations 1. MIRU Nabors 22E. · Notify the North Slope AOGCC representative 24 hours prior to testing BOPE. 2. Circulate out freeze protection. Set TWC. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull 7" x 4-1/2" x 3-1/2" tubing. 5. Set cement retainer at ___7465' and test to 3000 psi for 30 minutes. 6. RIH with 7" Baker whipstock assembly and set whipstock on cement retainer. Displace well with drilling fluid while milling the window. 7. Kick-off drilling the 8-1/2" intermediate section to TSag @ _+9943 md. 8. Run and fully cement a 7", 26# intermediate liner with a minimum of 150' liner lap in the 9-5/8". 9. Test the 7" and the 9-5/8" casing from the 7" landing collar to surface to 3000 psi for 30 minutes. Drill the 6" production section building to horizontal targeting the Zone 1 (Romeo) sands to an estimated depth of 10,832'. Run DPC logs from horizontal to 7" shoe. Drill the 6" production section horizontally with GR/Dir/4 Phase Res. To an estimate TD at 12,581' Run and fully cement a 4-1/2", 12.6# production liner with a minimum of 150' liner lap in the 7". Test the 4-1/2", 7" and 9-5/8" casing from the 4-1/2" landing collar to surface to 3000 psi for 30 minutes. The 4-1/2" production liner will be perforated with DPC 2.75" guns on a 200 psi under balance. Perforating details to be determined after reviewing logs. Run 4-1/2" completion tying into the 4-1/2" liner. Test the tubing to 3500 psi and annulus to 3000 psi for 30 minutes. Nipple down the BOPE. Nipple up and test the tree to 5000. psi. Freeze protect the well to -2200' and secure the well. Rig down and move off. Estimated Start Date: June 23, 1997 C.
