Wyman Cc: Hobbs, Greg S (ANC); Tirpack, Robert B; NSU, ADW Drlg Rig 9es; Engel, Hany R Subject: RE: P&A the ADN4 nuclear source on 14-23A Paul, In response to your questions below, please note the following: 1. At this time, our planned top of fish will be at 11,803' MD based upon our planned back-off at between the 2 joints of HWDP above the drilling jars in our current BHA (see 2 attachments), therefore, the length of the BHA left in the ground will be 220' with the radioactive source being located in the ADN tool ~98' from the top of the "fish". 2. If it is determined that the BHA cannot be recovered, the P&A above the "fish" will include a minimum of 200' of 17.0 ppg class G cement. 3. The following outline details our path-forward attempt to recover the BHA (which includes the ADN tool). 5!4/2009 Page 3 of 3 a. RIH with E-line and set string shot at 11,803' MD (between the 2 joints of HWDP as indicated above) and back-off the "fish". (NOTE: Will make multiple attempts as required to back-off/sever drillstring at this 11,803' MD depth to allow us to get a fishing assembly into the hole to "try" to jar/recover the "fish".) b. Spot 50 bbls of 8.6 ppg SFT spotting fluid on top of the "fish". c. POH with drillstring from the back-off at 11,803'. d. RIH with fishing assembly to include fishing jars and screw into "fish". e. Jar on "fish" until the "fish" is recovered or until it is decided that the "fish" is not recoverable and that a P&A is required. f.

Safety concerns and spacing limitations with the wellhead height and tubing spool preclude us from installing a spacer spool in the three-ram drilling BOP stack. Disposal No annular injection in this well. Cuttings Handling: Cuttings generated from drilling operations will be hauled to grind and inject at DS-04. Any metal cuttings will be sent to the North Slope Borough. Fluid Handling: Haul all drilling and completion fluids and other Class II wastes to DS-04 for injection.

The well has TxIA communication through the control line (SSSV nip at 2151' MD). 2. There is a "suspected" production packer leak at 9445' MD. 3. The IBP at 9470' MD leaks. Proposed Pre-R,ia Work: Load the tubing with seawater and fish/recover the IBP in the 4-1/2" tubing at 9470' MD. Set DSSSV in SSSV nipple at 2151' MD to eliminate TxIA communication. Perform an injectivity test which will dictate the P&A plan to be used on this well. a. IF there is adequate injectivity into the perforations (>2-3 bpm at <1500-2000 psi), the Option "A" P&A will be performed which involves a cement down-squeeze below a retainer placed in the 5- 1/2" tubing at -9380' MD. b. IF there is NOT sufficient injectivity to the perforations (<2 bpm at >2000 psi), the Option "B" P&A will be performed which involves making tubing punches in the 4-1/2" & 5-1/2" above the production packer at 9445' MD and then spotting a balanced cement plug from above a CIBP set in the 4-1/2" tubing at 9490' MD as the 1St cement plug to be placed in the welt during the planned pre-rig work followed by placing a 2"d cement plug above a CIBP in the 9-5/8" casing at -9380' MD after the rig has moved on the well and pulled the 5-1/2" completion. 4. Pull DSSSV from SSSV nipple at 2151' MD. Option "A" P&A a. Make tubing punch at -9440' MD in the middle of the 10' 4-1/2" located just above the 9-5/8"x4- 1/2" production packer at 9445' MD. b. Make tubing punch at --9354' in the 2nd full joint of 5-1/2" tubing above the production packer at 9445' MD. c. Circulate the well to seawater through the tubing punches at -9400' & 9354' MD. d. Set retainer in the 5-1/2" tubing just above the tubing punched holes at -9334' MD. (Note: The distance between the retainer and the top of the perforations 708'.) e. Squeeze ~34 bbls of 15.8 ppg G cement below the retainer at 9334' MD (a volume of cement equal to the cased hole volume from the base of the retainer at 9334' MD to 10,162' MD (100' below the bottom of the lowest perforation at 10,062'))'. f. Un-sting from the retainer and re-circulate the tubing side to clean seawater. g. After cement has reached a minimum compressive strength of 500 psi, CMIT-TxIA to 2160 psi (.25 psi/ft to TVD of 9-5/8" casing shoe at 8625' TVD). h. Assuming a good CMIT in Step "g", jet cut tubing at 7000' MD and circulate the well to clean seawater. Option "B" P&A a. Set 4-1/2" CIBP in well at 9490' MD in the 4-1 /2" tubing just above the 3-1 /2" liner top located at 9495' MD. b. Make tubing punch at 9440' MD in the middle of the 10' 4-1/2" located just above the 9-5/8" x 4- 1/2" production packer at 9445' MD. c. Make tubing punch at -9354' in the 2nd full joint of 5-1/2" tubing above the production packer at 9445' MD. d. Circulate the well to seawater through the tubing punches as detailed above. e. Set a -8.2 bbl balanced cement plug above the CIBP in the 4-1/2" tubing at -9490' MD which is a volume of cement equal to the tubing x 9-5/8" casing annular volume from 9445' MD up to the tubing punch in the 5-1/2" tubing at 9354' MD and the tubing volume from the top of the CIBP at --9490' MD to 200' up the tubing string to -9290' MD). f. Pull out of the balanced cement plug to above -9290' MD and re-circulate the tubing side to clean seawater. g. After cement has reached a minimum compressive strength of 500 psi, CMIT-TxIA to 2160 psi (.25 psi/ft to TVD of 9-5/8" casing shoe at 8625' TVD). h. Assuming a good CMIT in Step "g", jet cut the 5-1/2" tubing at -9172' MD in the middle of the Stn joint of the 5-1 /2" tubing (est TOC at 9290' MD) and circulate the well to clean seawater. (NOTE: The remainder of the P&A will have to be done after the rig moves onto the well and successfully pulls the existing 5-1/2"completion from the tubing cut at 9172' MD.) DS14-23A Sidetrack Page 7 i. With the rig on the well, pull the 5-1/2" tubing from the cut at -9172' MD. j. PU drillpipe and make a 9-5/8" clean-out run to the top of the tubing stub at 9172' MD. k. RIH and set C/BP at 9142' MD (~30' above the top of the tubing stub.. 1. Set 200' balanced cement plug (~15 bbls) on top of the C/BP (estimated TOC at -8942' MD). m. After cement has reached a minimum compressive strength of 500 psi, CM/T-TxIA to 2160 psi (.25 psi/ft to TVD of 9-5/8" casing shoe at 8625' TVD). 5. Perform a PPPOT -T to 5000 psi & PPOT-IC to 3500 psi. 6. Cycle all LDS, repair or replace as needed. 7. Freeze protect IA and T with seawater and 2200' TVD of diesel. 8.

Well Control A. With the KOP for the 8-1/2" hole in the Colville "below" all Cretaceous injection activity, pore pressures for the intermediate hole should be "normal" (8.5 ppg) to less than normal as the interval is TD'ed into the Sag River formation (the Sag in this fault block is expected to be under- pressured at 7.4 ppg EMW). II. Lost Circulation/Breathing A. For the 8-1/2" intermediate hole, the lost circulation/breathing potential should be minimized due to the relatively deep KOP in the Colville and given the fact the well has been design to minimize the hole angle into the top of the Sag (42 deg) to keep the mud weight relatively low (10.6 ppg). However, as there may be no cement behind the 9-5/8" casing at the KOP and given the potential for a "weak" zone within the Colville below the KOP, lost circulation/breathing problems must be considered a possibility. There is also a fault crossing in the lower Kingak which should be drilled with caution as it may relate to lost circulation and/or wellbore instability issues. B. As for the production interval of the well, lost circulation in the Sag River formation is usually fault related. And as this well will drill across 3 faults within the Sag River, the lost circulation potential while drilling this interval of the well has been rated "moderate". Please refer to the MI mud program for details as they relate to dealing with lost circulation problems while drilling this interval of the well. III.

Stuck Pipe A. For the 8-1/2" intermediate interval of the well, insufficient/poor hole cleaning support resulting in stuck pipe will be of primary concern. B. For the 6-1/8" production interval of the well, both differential sticking and sticking as associated with insufficient/poor hole cleaning should be of primary concern. VI.
