Item 5: Indicate which elevation is used as reference (where not otherwise shown) for depth measurements given in other spaces on this form and in any attachments. Item 16 and 24: If this well is completed for separate production from more than one interval (multiple completion), so state in item 16, and in item 24 show the producing intervals for only the interval reported in item 27. Submit a separate form for each additional interval to be separately produced, showing the data pertinent to such interval. Item 21' Indicate whether from ground level (GL) or other elevation (DF, KB, etc.). Item 23: Attached supplemental records for this well should show the details of any multiple stage cement- ing and the location of the cementing tool.

Attempted to circulate at 2 bpm, bul could not establish returns. Proceeded to lay an 8 bbl plug of class "G" cement with 20 lb/bbl "perfect seal." Shut down before pumping cement and reduced rate to 0.$ bpm once the cement was at the nozzle in order to establish a near- balanced condition. Slickline tagged cement at 9812' corrected which is 288' above top perf. Pressure tested to 400 psi twice after TD tag. Obtained slow leakoff after each test. considered inconclusive because there are still live GLV's in the well. Rigged down.

Notify an AOGCC representative prior to commenting plug-bacK operations. Run in with coil tubing while circulating seawater to kill well, Lay a cement plug starting from PBTD,(~ approx. 10244'), Squeeze down and leave the. top.of cemenl at least 100 above the top. perforation but below the packer. Thermore, the top of cement should be somewhere between 9900' and 1~65S' MD. See attached completion diagram. With AOGCC representative on location to witness operation, run in with slickline and confirm that top of oemont is at least 100' above the top perforation. . If tho cement la tagged more than 100' below the lubing tail, set a magna-range plug in the tubing tall to prevent future fluid swap-out when laylng a kick-off plug, Run in with a Jet / chemical cutter on E-line and cut the tubing in the first full above the packer PBR based upon the original completion tubing tally, Circulate well over to seawater and freeze 13mteot well with diesel from surface to 2000'MD. B. Bleed any pressure from the tubing, inner annulus and outer annulus to zero. 7. Install a back-pre,ute valve, Remove the well house and flowlines. Level the pad and dig out the cellar. Prepare the pad for arrival of the rig, MIRU with drilling rig..Gel a 9-5/8" bridge plug at +t- 7050' MD, Upon completion of mlMng a 50' section from the 9-5/1~" casing from 8700-8750' MD, a kickoff cement plug. will be laid with the base of the cement plug extending 100' MD below the secbon window to 8850' MD, The bridge plug se!s within 300' MD of the bottom of the milled 8action and the cement kickoff plug extending 100' MD below the base of the milled section will serve as the liner top cement plug. The 9-6/8" oastng is cemented or adjacent to an impermeable formation from the liner top to the milled so.ion.

RIH and mill or swage out restriction in 7" liner at 10027'. RU WL and run a Kinley Caliper Survey thru 7" liner to evaluate liner damage and determine if 5" concentric liner is needed. RIH with 7" retrievable test packer on 3-1/2" drillpipe to 9900'. Set the packer and test the 9-5/8" casing and 7" liner lap to 3000 psi with the outer annulus open. Unseat the packer or open the bypass. RU E-line and RIH thru the drillpipe with a 1-11/16" GR/CCL/Temp tool and perfom a Pump in Temperature Survey (PITS) using cold seawater to obtain 10 deg. of cooling at the perfs to determine if cement channel is present. POH. If cement channel is present, RU Schlumberger and shoot 10' of squeeze perfs using the 12 spf spiral squeeze gun. (Perforation depths will be decided based on PITS Icg). RIH with cement retainer to +20' above squeeze perfs and pickle the drill pipe with 12 bbls 15% HCI and reverse out to transport for disposal. Acid wash 7" liner with 24 bbls 15% HCI to remove scale and overdisplace. Set retainer +20' above squeeze perfs and cement squeeze all existing perforations with approx. 60 sacks Class G. Clean out the 7" liner to top of retainer and test the squeeze to 1500 psi. Clean out to PBTD ~f 10447'. Step 20 thru 25 are contingent upon the Kinley Survey results but are included in the AFE Estimate as the worst case scenario. Run 750' of 5" concentric L-80 liner and cement in place with approx. 100 sacks Class G cement. RIH with 8.5" bit and clean out to the 5" liner top at -9700', reverse circulate.

Pull the SSSV and run a drift to ensure no obstruction exists in the wellbore to a depth of 10000 ft. Do not go deeper than this as there is a bad spot in the casing at 10020 ft. Ensure check valves are holding to prevent placement of acid in annulus. Gas lift valves should not be pulled and dummied off as this will be a Iow pressure job. Rig up service company for a bullhead acid job. Acidize the Sag River/Ivishak with 3000 gals (71 bbls) of 15% HCL containing 5% xylene. Maximum pressure is 2000 psi but expected treating pressure is around 500 psi. Filter all fluids that will enter the formation to 3 microns. Operator may want to use a hydrocarbon base fluid for part of the flush to prevent surface lines from freezing. Fluids to be pumped into the formation are as follows: 20 bbls seawater preflush, 71 bbls acid, and 20 bbls seawater post flush. Acid is to be pumped into the formation in stages as given below to allow for soak time. A 30 minute shutin period should exist between all stages. Objective is to have acid soaking on perforations for 5-6 hours. Periodically pumping will ensure live acid is continually placed across the perfs.

BOX 6612 ANCHORAGE, ALASKA 99502~612 August 8, 1985 ~.~e Well U-11 (31-20-11-13) PBU Gentlemen' In accordance with the Prudhoe Bay Field Rules and Sohio's policy for drilling the first well on a new pad or a pad previously drilled, a 20" Hydril diverter system was used when drilling the surface hole on U-12 (41-13-11-12). ,. We did not experience "an~ surfaCe gas during the drilling of the 17-1/2" hole on Well-U-12 and believe it unnecessary to continue the use of the 20" Hydril diverter system on Pad U. We, therefore, request that Rule 4(b) of Conservation Order No. 145 be waived for U-11. Yours very truly, SOHIO ALASKA PETROLEUM COMPANY R.S.
