As there is no need for a USIT log on the existing 9-5/8" production casing, there will be no E-line USIT/CCL/GR logging as indicated in Step#5 of the "Planned Rig Work" on pages 1 & 10. 2. As we are now using a new version of Kick Tolerance software,the planned FIT prior to drilling ahead from the 9-5/8" window will now be 11.0 ppg (the previous target value was 10.7 ppg assuming a 9.5 ppg max pp/now assuming a 10.0 ppg max pp) and the planned FIT prior to drilling ahead from the 7" shoe will be 9.1 ppg(the previous target value was 8.8 ppg) see pages 7 & 12. Per the PTD (212-104), it is clear that we will work on a 7 day BOP test cycle throughout this well or notified otherwise and that a rig inspection by your Slope Inspectors is required prior to beginning work on this well. If you have any questions or concerns, please advise.

The maximum anticipated surface pressure from the Put River sands with a full column of gas from TD to surface is -3235 psi (assume 9.5 ppg as max PP at the Put River sands). This well will be drilled by Parker 273 using their 5000 psi four preventer BOP stack (3 rams and an annular). The BOP's will be tested to 3500 psi. The sidetrack plan for the 02-12D includes the following: 1. As pre-rig work; a. place a -500' cement plug on both sides of the tubing from -9638' MD (est. TOC at 9138' MD). b. make a tubing cut at 8800' MD. 2. With the drilling rig on the well; a. pull the 4-1/2" tubing from 8800' MD. b. Clean-out the well to the top of the tubing stub at 8800' MD. c. Set an EZSV at -8496' MD and test. d. Run 9-5/8" whipstock and set on the EZSV at-8496' MD. e. Change-out tubing spool and 9-5/8" pack-off. Proposed Pre-rig prep work: 1. MIT-T to 3000 psi. MIT-IA to 3500 psi. MIT-OA to 2000 psi. 2. Perform a tubing punch just above the existing production packer at 9599' MD (tubing punch at -9540' MD) to allow fluid circulation to the IA at that depth and circulate the well to clean seawater on both sides of the tubing. 3.

At surface, the 02-12 well is —60' north of the 02-35 well and —120' south of the 02-13 well. Close Approach Shut-in Wells: • Three off-set wells fail Major Risk analysis for their close approach proximities within the pay zone, however, all 3 wells pass Minor Risking at 1:200. Two of these wells (02-3A & 02-21A) are P&A'ed CTS's which are now buried under new CTS's and the other well (02-03B) is an active producer which will be SI and fluid packed for the drill-by. • The 02-12C leg of this sidetrack is currently Minor Risk at 1:1 which permits the close proximity drill-by in the pay zone of this well. Note: This well is in part, a replacement well for the02-12C "failed" CTS. • Note also, that the 3 Put River wells (the 02-27A and 02-23A producers plus the 01-08A injector) will be 4, SI while drilling intermediate section of this well.

Prior to picking up or running any equipment or tools in the hole, a PJSM and discussion is required to identify and note any equipment which will be run through the BOPE and is non- shearable. A risk assessment shall be performed for any equipment which is deemed non-shearable. The risk assessment must address the following: 1. Can variable bore rams seal against the equipment? 2. Can an annular preventer seal against the equipment? 3. Is a cross-over readily available to make-up into equipment? 4. Is a single joint or full stand of DP readily available to lower equipment below the BOPE stack? 5. How the equipment can be intentionally dropped down hole. 6. Are weights of equipment known so that hydraulic jacking force of wellbore pressure can be calculated. 7. Accurate and up to date shearing capabilities for the current shear rams installed is available. 8. Has each crew member been versed on individual roles and responsibilities? If there is a well control event happens with non-shearable equipment across the BOPE shear rams, the following procedure should be followed: 1. Based on the risk assessment above, gain control of the well by either: a. Closing the appropriate preventer(pipe ram, VBR, or annular) or b. Placing a sealable piece of equipment across the BOPE and closing the appropriate preventer or c. Dropping equipment and closing the Blind or Blind/Shear rams. 2. If well conditions permit, contact appropriate personnel. If not,proceed with well kill operations. This may include placing shearable equipment(i.e. drillpipe)across the shear rams by stripping in/out of the hole. 02-12D PTD Page 9 7/24/2012 02-12D RST General Operational Summary Proposed Pre-rig prep work: 1.

Intermediate Hole - The planned 10.4 ppg mud weight for this interval of the well, there will be sufficient hydrostatic head to provide the following: 1. sufficient mud weight for potential cretaceous injection pressures (9.8 ppg max). -- 2. sufficient mud weight for Put River and Sag River pore pressure (9.5 ppg max). • 3. sufficient mud weight for HRZ and Kingak shale stability. B. Production Hole - The Ivishak in this area is expected to be under-pressured at 7.1 ppg EMW. This interval will be drilled with a 8.5 -8.8 ppg reservoir drill-in fluid. . II. Lost Circulation/Breathing A. Intermediate Hole - While no major lost circulation is expected in this interval of the well, breathing and/or lost circulation is a possibility on wells with KOP's from un-cemented casing. B. Production Hole - The lost circulation risk for this interval of the well has been characterized as"low". III. Kick Tolerance/Integrity Testing A. With the planned mud weights, the kick tolerance for the intermediate section is infinite for both intervals of this well. B. Integrity Testing Test Point Test Depth Test type EMW (lb/gal) 9-%" window 20'-50' from the 9-%" window FIT 10.7 minimum 7" shoe 20'-50' from the 7" shoe FIT 8.8 minimum IV. Hydrogen Sulfide While there are no wells on DS 02 with >100 ppm H2S, operations should adhere to the guidelines in - the ADW"Hydrogen Sulfide" SOP. V. Faults - no mapped faults. VI. Anti-Collision Issues A. There are 2 P&A'ed CTS's (02-3A & 02-21A) and 1 active producing well (02-3B) which fail Major Risk analysis and have been Minor Risked at 1:200 to drill this well. B. The 02-12C leg of this well has been Minor Risk at a 1:1 to drill this well. Minor Risking this leg of the well at 1:1, basically means we are willing to "hit" this well as we drill this replacement well. C. 3 Put River wells (the 02-27A and 02-23A producers plus the 01-08A injector) will be SI while drilling the intermediate section of this well.
