A RWO package was put together to fix the leak but at the last minute the RWO was cancelled due to economics. Unfortunately all the rig prep-work had already been completed so the tubing was already cut. Current Status The well is currently classified as "Non Operable" by BP due to the IA x OA communication and the cut tubing. Objective The objective of this job is to restore well barriers and bring the well back to operable status. New technology/methodology has brought about a non-rig option of performing an OA down- squeeze to fix the IAxOA leak. The tubing cut will be repaired by performing a packer squeeze - which will cement the tubing in place. Procedural steps Slickline 1. Pull IBP 2. Pull Hold-Open-Sleeve (set currently across SSSV) 3. Run Custom big-bore Hold-Open-Sleeve Fullbore 4. Establish injectivity rate and pressure with diesel or crude oil down the OA and into formation. Max OA pressure 2500 psi. 5. Pump -290 bbls of 15.8 ppg Class G cement down the OA to fully cement the OA from surface to the Surface Casing Shoe. Pump the following schedule at maximum rate below 2500 psi treating pressure: ➢ 10-bbls of 60/40 or 10 bbls neat MEOH ➢ 80 bbls hot (180 deg) freshwater + surfactant; 2 gal/bbl F103 and 2 gal/bbl UO67 ➢ 10 bbls of 13.5 ppg MUDPUSH II Spacer ➢ 20 bbls of neat cement ➢ 50 bbls of cement with 15-ppb aggregate • ➢ 220 bbls of neat cement • Volumes: top bot volume MD MD Size ID bbls/ft.

Well was found to have an IAxOA leak that became unmanageable by bleeds. A RWO package was put together to fix the leak but at the last minute the RWO was cancelled due to economics. Unfortunately all the rig prep-work had already been completed so the tubing was already cut. New technology/methodology has brought about the option of performing an OA down-squeeze to fix the well but the cut tubing would also need to be repaired. To fix the tubing a packer squeeze will be performed to cement the tubing in place. An OA down-squeeze will then be performed to repair the IAxOA leak. Current Status The well is currently classified as "Non Operable" by BP due to the IA x OA communication and the cut tubing. Objective The objective of this job is to cement the cut tubing via packer squeeze. After achieving a passing MITIA, the OA would be fully cemented via downsqueeze from surface to make this well operable. Cement will be pumped down the OA from surface in two stages (if needed). The objective is to have cement in the OA from the surface casing shoe to surface. Any voidage in the OA left after the cement jobs will be filled/squeezed with well lock, squeezecrete, or similar, if needed. Procedural steps Fullbore 1. Establish injectivity rate and pressure with diesel down the OA and into formation. Slickline 1. Drift through tubing cut. 2. Pull IBP or release it and push it through tubing tail and drop it off at PBTD (rathole). E-Line c v 1. Set CBP just above production packer. Coiled Tubing 1. Perform packer squeeze with cement, bringing cement in the IA 100'-200' above tubing cut. Fullbore ) 1. MITIA to 2500 psi. ( i`y� (-)/ l<! c){ `'` Coiled Tubing M ) TT bCi )' C kv1J'/1 a'16 e43P 1. Mill any remaining cemenTfrom tubing and mill out CBP. Cementers / 1. RU to the OA. 2. Pump enough cement to fill OA to surface displacing OA fluid into formation. SI and allow cement level to reach equilibrium. 3. WOC to build strength. 4. Pump a second cement job to refill OA to surface (if needed). DHD 1. Bring well online under evaluation and monitor OA for re-pressurization. 2. Make well operable if OA does not re-pressurize or is managable by bleeds. Special Projects (pending, if OA re-pressurization is not managable by bleeds while online) 1. Strap the TOC in the OA. 2. Fill and squeeze the remaining void in the OA with well lock, squeezecrete, or similar product. DHD 1. Bring well online under evaluation and montior OA for re-pressurization. 2. Make well operable if OA does not re-pressurize or is managable by bleeds. 2 TREE-= CliN 0 .., 3 AANNOTES:'4-1/2"CHROME TBO'' WELLHEAD= RC 09-4o I ACTUATOR; BAKER C CEB.EIEV= 52' I i BF.a.ei; 7 tO3P= 1600' — - , - 2197" 1-f 4-1/2"AV A TRSV SSSV,D.3.8r 20"OONDUCTOR, - --113 li Ilex Angle= 64°fli 10800 -----1 219T -3.85"h-OU)OFEN SLV vs I ANCHOR, 131 5#, Datum IC= 14781* 0.2.8- (02/09/15) 'Datum 1VD. 8800.s's- 13 19 124' 13-3/8-CSG,68*,L-90/K-55.ID=12.4W - 4378 7-4 _II GAS LET MAJUS ST Poo ner: DEV-TYPE VLV LATCH PORT' DATE 1 3140 2981 41 )4 •TE •DONE TG 1 16 C6/28/92 Minimum ID -2.80" @ 2137' i 2 6801 49651 61 1 TE DONE TG 1 16 C6/2W92 1 3.85" HOLD OPEN SLEEVE 1 : 3 9156 6088' 61 TE DLIV TG 0 C2/25/91 4 10343 6706 63 TE UM TG 0 17131/91 5 11312 7147 62 TE ECHE TG 16 C6I28/92 1 , 6 11943 7447 62 TE DI& TO 1 0 C2/25'91 7 12566 77421 61 IE DIM TG 0 C2/26/91 8 13196 80371 63 TF DLW 16 0 C2/25/91 - 1-TBGPI-NCH(02/72717141:1358 -1436Z 1-----... i 9 13786 83281 59 i TE DAM TO 0 C2/25/91 II ,... 1 1 10 14335 J381-81 5/ 1 TE SO 10 24 ;C6/28/92 4-1/2-TBG Oft(02113/15) -1 143817 . —11'1 14408* 1-12-1fr BKR BP402/11/154 C-D",-r' II 14444' –14-1/2-131cR LOC SEAL ASSY.ID=3.875" 144W_j 0-648"X 4-1i:-e-sKRS9-3A PERM PKR1)=1 .7.71 , 14480' Hr BKR MI..LC471 EX 113.610N15 600l, ----------, 14466' '-17"X 4-ltr X0.0.3.94" I roe oF r E.r.s4-rtisAuc - 145111' I--- I 14618* :---19 we-x s 14"BKH I t-iiK SLV,10 8 I ar 1 14825. 1-73:Yr X f-OP3N rfy FLO 1 L IP'hIGR,ID- 9 1131 1 14631' –19-518-X r TI33ACK SLY.ID=7_50" .., 14638" –9-5/8"X r BRN HY FLO I LTRFICiR,KO=6 187" I 4-1/2"THG,12.84,13CR,_0152 epf, 13 x 3.998" – 14672' - 1 14560" –4-1,2"011S XN MP,ID=3.725" I I 9-5/8"CSG,474,L-80 13TC,ID.,--8 681" – 14871' ,, 14572' 4-Ix SKR FOX SHEARCLIT SLJES,0=4 OW FERFORATiON aJLOAARY REF LOG:CET ON 03/1491 ' 14677 H4-1/2"WLEG,D 3 9513- A1L2E AT TOP PEW 61 rf! 141387' 14562' Hama-rr LOGGED 04/04.3 Li 11 f.ble:,Refer k Prod Lic6o1 n DB for histrical perf arta I svE" SPF NTERVAL Opn/Sqz SHOT SOZ 3-3/3" 4 14988-15000 0 04)06/91 3 3/8" 4 15012- 15043 0 04/015/91 I 3-3/3- 4 15077-15086 0 040591 3-3/3" 4 15096-15105 0 04105/91 )46 I I 14965' -FISH- 1-1/7-OGLV-MISSING FROM pocxEr ___ _____ , _ __ ______ 3-3/9" 4 15111-15128 0 04,05191 I pEs=o -I 16181' ; 114104.1 0.00414 7'LNR 294/,L-80 BTO 0371 bpf.D=0.184' - 16227' .11111.11 4411,01•611. .014.441 41.4411.... =D ---1 1526(Y I ........._.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations.

Grimaldi]/)~~~/r~ Petroleum Inspector TELEPHONE NO: RIG/BOPE Inspection SUBJECT: AAI DS 9-48 Prudhoe Oil Pool Permit No. 91-04 TJh~arsdav__2/2!/91: I performed a RIG BOPE inspection on Nabor~s rig #28E drilling well DS#9-48 for Arco in Prudhoe Bay. The rig and location were in satisfactory shape with the following exceptions: On the accumulator, there was evidence of leakage of hydraulic fluid from the pipe connection. I isolated the accumulator banks from the system and lost 50 psi within five minutes, The toolpusher, Laverne Linder~ will clean the system and determine where the leaks are coming from. The fire protection on the control lines leading to the BOP stack (a previous failure) are approximately 50% repaired and the rest of the armour is on order~ I found no kill sheet in the doghouse but one was placed on the wall before I left. All else on the rig appeared good~ In summary: Upon the next inspection, the preceding failures should be rectified. No other problems were observed.

The annulus will be left with a non-freezing fluid during any extended period. The annulus will be sealed with 300 sx of cement followed by Arctic Pack. b. Minimum distances of wells within 200 ft. of the proposed well are: o DS 9-14: 58.39' @ 600' MD / 600'TVD o DS 9-15: 60.00' @ 0' MD / 0' TVD o DS 9-13 : 178.94' @ 500'MD / 500' TVD o DS 9-16 : 178.49' @ 900'MD / 899' TVD c. The drilling fluid program and surface system will conform to the regulations set forth in 20AAC25.033. d. Maximum surface pressure is based on BHP and a full column of gas to TD (0.10 psi/fi). e. Based on previous logs on DS 9, no potential productive zones are anticipated above 3500' TVD. f. No potential hazardous levels of H2S are anticipated in this well.
