As the attached ARCO wellbore schematic shows a cement plug was placed from 10,775' to 9,390' to cover the perforations at 10,630' to 10,686'. The ETOC was 9,590', CTUM, but the cement was tagged at 9,390', WLM. Some of this error can be accounted for due to the difference in the CTUM and the WLM. The tubing was pressured to 1,550 psig and lost to 1,490 psig in 30 minutes. Summary:. I witnessed the pressure test and tagging of the cement plug set in ARCO's PBU well DS 2-30 to P & A the existing perforations in preparation to side track this well.

Placement of ap- proximately 36.1 bbl cement will include a _+ 5 bbl squeeze into perforations, leaving _+ 31.1 bbl inside 3-1/2" tubing, _+ 1122' above the top perforation.

Notify AOGCC prior to commencing P&A operations. . RU and establish injection using seawater. Bullhead seawater down tubing to kill well. Mix and pump the following: 5 bbl fresh water/gel spacer, 36.1 bbl (202.7 ft3) Class G cement, 5 bbl fresh water/gel spacer, 61 bbl seawater, 30 bbl diesel. Con- tinue pumping (with diesel) until_ 5 bbls cement is down-squeezed into perfora- tions from 10,630'- 10,686' MD leaving _ 31.1 bbls (___ 1122') cement above top perforation. Proposed TOC is _ 9508' MD (top of production packer). NOTE: Diesel displacement is to freeze protect well (to _+ 2,000' MD) until tubing is cut and wireline dummy run can be made. Diesel displacement may be elimi- nated if tubing cut is done quickly and the well circulated to diesel prior to releasing the well to drilling. DS 02-30 P&A Summary Page 2 If injection cannot be established, a coiled tubing unit must complete the P&A. Cir- culate 31.1 bbl (174.6 ft3) above top perforation (10,630' MD), PU coil, clear tools and POOH. 3. RU slickline unit and make dummy run to TOC. If required by onsite AOGCC repre- sentative, pressure test cement plug to 1,500 psi. Tag and record TOC. · Have AOGCC representative on location during testing and tagging operations. · Carefully monitor final cement displacement to avoid leaving excess cement in tubing. · Be prepared to RU CTU and drill if cement is encountered higher than 100' be- low bottom of 7-5/8" milled section @ 8540' MD (max TOC 8640' MD). 4. RU electric line unit with tubing cutter. RIH and cut 3-1/2" tubing at _+ 8700' MD. 5. RU and reverse circulate seawater through the tubing cut until returns are clear. Freeze protect well with diesel to 2,000'. 6. Test 7-5/8" pack off to 5,000 psi and service lock down studs. Notify Rig Repre- sentative immediately of any pressure test or wellhead condition problems. 7. Release all pressure from the tubing, inner and outer annuli. , Install a BPV and test same to 1,000 psi against the cement plug. Remove the well house and flowlines. Prepare for the arrival of the rig. Level pad and dig out cellar if necessary. Drilling ~ Procedure 1. MIRU Nabors 2ES. 2. Pull 4-1/2" x 3-1/2" tubing. Mill section in 7-5/8" casing from _+ 8490' - 8540' MD. Set sidetrack kick-off plug from _+ 8290' - 8640' MD (SSD recommended practices). . Kick off (_+ 8500' MD) and directionally drill a 6-3/4" hole to 10,709' MD (90° incli- nation). Run and cement 5-1/2", L-80 liner in Zone 1 at _ 90°. Directionally drill a 4-3/4" lateral hole to _ 11,760' MD. . Completion operations entail 3-1/2", L-80 solid, cemented liner and 3-1/2" x 4-1/2" L-80 tubing. Three GLMs will be run with a permanent packer set inside the 5-1/2" liner top. Prepared by: Operations Drilling Engineer GeoQuest 500 w.

Excess non-hazardous fluids developed from well operations and as necessary to control fluid level in reserve pit will be pumped down the 10 3/4" x 7 5/8" annulus. The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sxs of cement followed by Arctic Pack. b. Wells within 200' of the proposed well are: DS2-16 DS2-17 DS2-18 DS2-28 180' at surface 60' at surface 19' at 997'tvd/1000 md 120' at 500'tvd/md c. The drilling fluid program and fluid surface system will conform to the regulations set forth in 20AAC25.033. d. The maximum surface pressure is based upon the BHP and a full column of gas to TD (0.10 psi/ft). e. Based upon previous logs obtained from DS2 wells, no productive zones are anticipated above 4000'tvd. f. No hazardous levels of H2S are anticipated in this well. 0 1~ 2~ 3~ 4~ 5~ 6000 7~0 0 - RI('B EI.I~'VATION 6R'~,,. 20" Casing TVD=-II~ TMI~IIg DEP--0 DS2.,30C ~. ,~0 o~.~ ~' ~' I" -- I~0' ~.o SILL: I~.o r ..o THL: BHL: H 1~1~ 14E 26 470' ~ 1860' FEL · 1" c~g ~D=3568 T 4~0~ D~=1576 ~ 4~ ~5187 D~227t .
