Drilling & Wells Coiled Tubing Drilling Team Well C-33 is scheduled for a through tubing sidetrack to be drilled with coiled tubing. The following summarizes the procedure required to prep C-33 for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of this proposed completion is attached. 1. A 2.75" drift will be run to pbtd. 2. The gas lift mandrels will be dummied off and a Mechanical Integrity Test is planned. 3. Service coil will pump approx. 45bbls of cement to P&A the existing perforations. 4. The window will be milled off of a cement ramp with service coil. The KOP will be at approximately 11,250'md (8790'tvdss). 5. A sidetrack of approx. 2500 ft into lower Zone 1 will be drilled with CT. 6. The sidetrack will be completed with a cemented 2 3/8" liner that will overlap the existing 3 W' tubing to -10,830'md (TOL). The estimated Top of cement is planned for 300' above the window to approx. 10,950'md The coil tubing operations are expected to commence December 4. Drilling coil is expected to begin the sidetrack drilling on December 10, 2000. Thomas M.

Because of geology considerations (faulting), the wellbore trajectory needs to be changed for the purpose of maximizing wellbore penetration thru producible sands. A cement plug is to be spotted between 12170' and 11670' md (400' into OH and 100' inside the 7" liner). After dressing off the cement plug, another 6" hole will be drilled to capture reserves within a sand interval within Zone I. This wellbore trajectory change will only result in a TVD change; an azimuth change is not warranted. ..I !,) f,.,'., ?. it Aiask~ Oil & {~as Cons, Cori~rn~ss\O¢ Anchora,qe DOYON 9 13 5/8" 5,000 psi Stack I 1.33 7.75 4.30 5.11 2.00 RKB 1 HYDRIL PIPE RAM BLIND RAM KR TO RF RIG Fl ©¢ 9.58 1 3.86 R 15.88 2.50 t" 3.13 2.33 GROUND LEVEL I MUD CROSS ,1 PIPE RAM 20.41 l' 24.79 MUD CROSS TBG SPOOL ASE FLG . 27.12 28.45 BP/AAI SHARED SERVICE DALLY OPERATIONS PAGE: 1 WELL: 0-33 BOROUGH: NORTH SLOPE UNIT: PRUDHOE BAY FIELD: PRUDHOE BAY LEASE: APl: 50- PERMIT: APPROVAL: ACCEPT: 06/03/93 10:00 SPUD: 06/03/93 03:00 RELEASE: OPERATION: DRLG RIG: DOYON 9 WO/C RIG: 06/04/93 ( 1) DRLG 16" HOLE MW: 8.8 VIS:300 TD: 700'( 700) MOVE TO 0-33, NU DIVERTER & FUNCTION TEST, P/U BHA & ORIENT MWD, SPUD IN DRLG F/110'-170', FISH OUT W/OVERSHOT, DRLG F/170'-700', SPUD IN @ 15:00 6/3/93 06/05/93 ( TD: 1629'( O6/O6/93 ( TD: 2490'( 2) PC~DH.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607. ton BY ORDER OF THE COMMISSION dlf/Enclosures cc: Department of Fish & Game, Habitat Section w/o encl.
