MASP: 2419 psi Estimated Start Date: May 13,2008 Pre-Riq Work: 1. Bleed casing and annulus pressures to zero. Cycle all LDS, repair or replace as needed. 2. Open OTIS FMX TRSSSV. 3. Set. a cement retainer at -8390 and squeeze -24 bbls of cement into perfs and fill tubing from 9395' up to 8390'. 4. Un-sting and lay 100ft of cement (-1 bbl) on top of retainer. 5. Drift for 3-1/2"Jet cut. 6. Jet cut tubing middle of first joint above top of cement ~ 8280'. 7. Circulate well with 9.8 ppg brine and freeze protect well with diesel thru the cut. 8. Close OTIS FMX TRSSSV. 9. Set a BPV and test to 1,000 psi from tubing annulus (or maximum allowable up to 1,000 psi). 10. Secure the well. 11. Remove well house. Level the pad as necessary. Riq Operations: 1. MI/RU Nabors rig 7ES. Pull BPV. 2. Set and test TWC to 1,000 psi. 3. Nipple down tree. Nipple up and test BOPE to 3,500 psi. Pull TWC. 4. Open OTIS FMX TRSSSV. 5. Pull 3'/z" tubing from pre-rig jet cut C~ 8280'MD. 6. Run USIT Log in 7 5/" casing up to surface. 7.

Circulate well clean, short trip to window. POOH. 18. Run and cement a 7", 26.0#, L-80 intermediate drilling liner. 19. Test the 7" casing to 3,500psi for 30 minutes. Record the test. 20. M/U 6 1/8" Dir/GR/Res assembly. RIH to the landing collar. 21. Drill out the 7" liner float equipment and cement to the shoe. 22. Displace the well to 8.4 ppg Flo-Pro drilling fluid. 23. Drill out the 7" shoe plus drill ~20' new formation; pull up into the shoe and conduct an FIT. Drill ahead to horizontal landing point. 24. POOH for bit / BHA change. Need to add Den/Neu to MWD, mad pass up from landing to 7" shoe. Drill horizontal section to planned TD, short trip as necessary. 25. Circulate, short trip, spot liner running pill, POOH. 26. Run and cement a 4'/z", 12.6#, L-80, IBT-M production liner. POOH L/D all drill pipe. 27. RIH with 2 7/8" pert guns and perforate ±1000'. 28. R/U and run 4'h", 12.6#, 13 Cr-80, VamTop completion tubing. Land the tubing RILDS. 29. Reverse circulate seawater and corrosion inhibitor. Drop the ball and rod, set the packer. 30. Individually test the tubing and annulus to 3,500psi for 30 minutes. Record each test. 31. Set a TWC and test to 1000 psi. 32. Nipple down the BOPE. Nipple up the tree and test to 5,000psi. 33.

Specific prep work, (Phase 1) and drilling, (Phase 2) operations are detailed below. pf> Phase 1: Isolate & integrity test inner annulus, (IA). Drift tubing and tag PBTD in liner, abandon current perforations and set cement plug for kickoff. Mill window if service coil is available. Planned for September 26, 2001 . Drift well and tag as deep as possible with slickline. . Liquid pack and integrity test the IA. . P&A the existing perforations at 9,212' -9,228' MD with cement. f\ ~ . Spot a cement plug from PBTD to approximately 100 feet above the kickoff point, which will be at '~a"d approximately 8,982' MD (8,598' TVDss). . Mill window with service coil if available. Phase 2: Drill and Complete CTD sidetrack: Planned for October 2, 2001 2" coil will be used to drill a -700 foot, 3" open hole sidetrack, (as per attached plan) and run a solid, cemented & perforated 2-3/8" liner completion. Mud Program: . Phase 1: Seawater . Phase 2: Seawater and Flo-Pro (8.5 - 8.6 ppg) Disposal: . No annular injection on this well. . All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. . All Class I wastes will go to Pad 3 for disposal. Casing Program: . 2-3/8", L-80, solid liner will be run from 8,418'MD (TOL, 8,144' TVDss) to TD at approximately 9,650'MD. Liner will be cemented to top of liner with approximately 14 bbls (annular volume plus 25% excess in OH) of 15.8ppg class G cement. Well Control: . BOP diagram is attached. . Pipe rams, blind rams and the CT pack off will be pressure tested to 300 psi and to 3,500 psi. . The annular preventer will be tested to 400 psi and 2,200 psi. Directional . See attached directional plan. . Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. Logging . An MWD Gamma Ray log will be run over the open hole section. . A memory CNL will be run inside the liner. Hazards . H2S not measured in this well, Not and H2S drillsite. . The well path will not cross any mapped faults. However, the well path is in the proximity of mapped faults, which creates a high risk of lost circulation along the proposed well path. Reservoir Pressure Reservoir pressure is estimated to be 3,300 psi at 8,800ss. Maximum surface pressure with gas (0.12 psi/ft) to surface is 2,235 psi.
