No Annular Injection In This Well: DS 6-10A Class !1 drilling wastes will be disposed at CC-2A grind and inject facility. If Class I wastes are generated, they will be taken to the Pad 3 disposal site. Pre- Rig Discussion The Wells Group will prep the well with non-Sundry operations: pad preparation, well integrity testing, tubing cut operations, fluid kill & .freeze protection. The Sundry P&A of the existing perfs will be performed after MIRU D-16 through an EZSV after milling and retrieving the packer and tailpipe. Drilling Discussion Well 15-15A is a planned horizontal Zone 1 sidetrack. The well will kick off in Zone 2 to avoid the Zone 3 chert for the directional work. KOP is planned for 10,618'MD. Maximum proposed DLS for the build section is 12 deg/100'. To reach the desired BHL, a short azimuthal course correction (185' @ 10 deg/100') will be required about midway through the horizontal interval.

The KOP is 48' below top of Z2 and believed to be below Z3/Z2 chert. Maximum proposed build DLS for the build section is 12.07 deg/100. No known wellhead, hanger, 13-5/8" or 9-5/8" annulus integrity problems are evident. The 9-5/8" x 5-1/2" annulus passed a Casing Mechanical Integrity Test of 3,000 psi on 2/12/98. The tubinq, 5-1/2", 17#, L-80 is plastic coated and should be noted in preparin.q the well for tubin.q cut operations. The tubinq is known to have leaks @ 4413'MD and suspected to have additional leaks. MANY JOINTS OF'TUBING ARE SHOWN TO HAVE -70% REDUCTION IN WALL THICKNESS PER 6/28/98 KINLEY CALIPER. Abandonment will be done by the Rig. The welll is expected to begin P&A Operations followed by a conventional sidetrack. Other Information: The 9-5/8" will be tested and the 4.5" liner will be tied back above t'he top of the existing 7" TOL. The production packer will be set in the 9-5/8" and the 9- 5/8" will be testing for.placement of a possible 7" shallow scab liner if needed. (' ( Drillinq Hazards/Contingencies PRODUCTION SECTION: · DS 15 is NOT an H2S pad.. · Losses during decompletion and production drilling are known to occur on DS 15. Pump LCM as necessary to control losses following the LCM decision tree for productive zones. · The highest formation pressure is estimated at 3379 psi @ 8890 TVDss (7.38 EMW) from offset well data. The overbalance while drilling with 8.8 Quickdril will be 689 psi and 550 with 8.5 seawater. SUMMARY REDRILL PROCEDURE: Pre-Riq Procedure 1. The Wireline group will kill the well with seawater. 2. Establish injection rate and pressure. 3. Drift 'Plastic Coated' tubing to 9800' MD (to XO below BOT packer). 4. Cut plastic-coated tubing at - 9720' MD, or in the middle of the first full jt above SBR seal assembly. 5. Circulate the well to SW if not done in the preparation for the tubing cut. 6. Test 9-5/8" casing packoff and tubing hanger packoff to 5000 psi (3500 if on slips) and cycle LDS. Plastic pack old packoffs if needed as wellhead/hanger/flange to be changed. 7. Freeze protect. 8. Bleed all wellhead pressures to zero. 9. Set BPV and test. Secure well. Remove wellhouse and flowlines & level pad. Summary P&A Riq Procedure 1. Perform Pre-Rig inspection with Pad Operator. Obtain and review handover notes and status of packoff test results. Confirm tubing cut. Ensure all wellhead pressures are zero, 2, MIRU D-16. Pull BPV and circulate well with treated seawater and keep well full. Monitor losses. 3. Install TWCV and test to 1000 psi. 4. ND tree & NU BOP and test. Pull TWCV. Monitor well & keep full. 5. Pull tubing hanger and 5.5" tubing from cut. Tubing is in bad condition per Kinley caliper and should be noted that some sections show 70% reduction in wall thickness. 6. Follow Baker procedure for retrieving the PBR/K Anchor, and milling and fishing packer. Push packer to TOL (7") before POOH. .,, 't. f o~ ~. 7. PU bit & scraper and cleanout to below E~ Whipstock setting depth @ >10,618 K__O~:,,., 8. PU EZSV on drillpipe and run in and set ~b_'c':,e ~bing cut to &',',ow ~qu~az~r;,,3 dc';;;';, -&-tubip~.
