It had a RWO and pert squeeze in 02/91. The squeeze was intended to close off a channel down to zone 3 and another channel up to 12,334' (-base of Sag). The squeeze was a complete failure: -46 bbls of cement were pumped, but squeeze / pressure never developed. A post-squeeze IPROF in 10/91 indicated an acceptable profile, so the well was never repertorated. The well had a second failed squeeze attempt with an inflatable cement retainer in 08/99 to shut off a channel down to Z3. The job was problematic: after pumping 6 bbls below the retainer, they couldn't get off of it. They dropped a disconnect ball. More cement was pumped and washed down to 12675'. Four days later, a slickline unit tagged at 12684' and got a sample of schmoo. Hall plot indicates that the injectivity increased for a short time. However, the well currently still has injection into Z3. e e The objective of this procedure is to squeeze off all open perfs, channels and eliminate zone 3 injection. After waiting on cement, reperfs will be shot and injection established in the upper poorer quality interval that has had the least sweep and has gas encroachment. Subsequently additional Zone 4 reperfs will be shot and the well returned to injection. If you have any questions or comments regarding this procedure, please call Jennifer Julian at (W)564-5663, (H)274-0929, (Cell)240-8037 or Bob Gerik at (W)564-4476. cc: w/a: Well File J. Julian J. Sack B. Gerik e e Primary Goal The primary goal is to squeeze all open perforations. Well has a channel down to Zone 3. Primary squeeze target: 12304'-12326', 12656'-12660', 12668'-12682', 12700'- 12714' (Z3). Current injectivity is 12000 BWPD @ 1014 psi = -8 BPM. Contact Jennifer prior to squeeze to discuss volume of aggregate in cement. NOTE: 13-19 had a similar squeeze: 45 bbls LARC with aggregate behind pipe. Pre-SQueeze FB 1. MIT-IA to 2500 psi.

Fluid pack well with -450 bbls 160°F filtered KCI water or seawater (-1.5 x well bore volume) at max rate to displace gas out of wellbore. After -450 bbls of water have been pumped, reduce the rate to -1 bpm in order to maintain BHCT. Well will be on a vacuum with a full column of seawater. Wellbore volume = 304 bbls to 12684' ELM (most recent deep tag) 5. RIH wi ball drop cementing nozzle (no check valves). 6. While pumping down backside (coil tubing by tubing annulus) only, tag PBTD with nozzle. Correct and pull up 10'. Flag pipe and pull uphole above 12250' (top perf). 7. Wash down as deep as possible. (SL tagged at 12684' ELM right after failed retainer squeeze pushing schmoo into perfs). 8.

Surfactant 0.2% - 0.5%* Iron Reducin A ent 20 Fe+3 concentration <300 m *concentration to be determined per emulsion/sludge testing. 9. Run down to as deep as possible and pump flush to ensure all acid is removed from well bore (acid is an accelerator to cement). If tag is deeper after pumping acid, pull up 10' from new PBTD and reflag pipe. Once the wellbore is flushed, pull nozzle above 12250' (top perf) and park. Ensure the acid is not brought to surface due to possibility of H2S formation. 10. Pump diesel down backside as necessary to achieve positive wellhead pressure under static conditions (not while pumping into the formation). Do not proceed with squeeze unless the well has positive WHP. 11. Batch mix 90 pumpable bbls LARC cement to meet the following specifications. Volume to Pump Cement Type Filter Cake Thickening Time Fluid Loss Target Acceptable Range Rheology 90 bbls total Liquid Latex Acid Resistant w/D-176, 3% BWOC w/ aggregate .85" firm cake ± 0.15" in lab 5-7 hours at 160°F SBHT 75 cc/30-minutes at 160°F SBHT 50 - 90 cc/30-minutes at 160°F SBHT YP>5 with no settling or gelation in fluid loss cell. 12. Catch a sample of the cement for QC testing. Line up cementers to the coil. 13. Pressure up IA to 1500 psi. Note: Assuming PBTD = 12684' ELM and 90 bbls of cement pumped, approximately 73 bbls of cement can be sQueezed behind pipe before the cement top in the liner falls within -100' of the top perf at 12304'). Note: Account for methanol, diesel, and cement densities when calculating DP at perfs (SBHP = 3250 psi at 8800' TVD). 22. With coil at of 3500 psi 5 minutes safety, close choke, and slowly walk squeeze pressure up to a target WHP at the perfs in 500 psi increments, holding each increment for Maintain 3500 psi for 1 hour. Note 90 bbl of cement would extend up the tubing to 9643' MD if the perfs take no cement before squeeze pressure develops (assuming PBTD at target of 12684' ELM). Pull up hole at safest maximum significantly higher due to small speed to safety at 9543' tubing capacities (5-1/2" May want to pu is 43'/bbl) 21 20. Position nozzle at cement top just as last barrel of cement reaches nozzle I up 19.0nce 1000 psi pressure bump is observed, open choke to take returns at 1000 psi and begin pulling up, laying in remaining cement at 1: 1 Maintain 1000 psi on the backside while taking returns and laying in cement. 18. Reciprocate just above the top perf at 12304' until wellhead pressure rises 1000 psi. Do not build squeeze pressure while across the perfs to prevent getting "noded" in 7. Pull up cement just above top perf to prevent dilution if perfs are taking 1 16. Do not pull uphole until -4 bbls of cement are out the nozzle. This will place the cement top -100' above nozzle in order to prevent dilution of cement while pulling uphole. After 4 bbls cement are out the nozzle, pull uphole and lay in cement 1 : 1 to cement 15.

Pump the fOllowing down e the coi reducer J313 as e it wi e e Note: If unable to achieve at least 2500 psi DP squeeze pressure at perfs, contact Jennifer and plan to pump leave a cement plug. 23. After one hour at 3500 psi, slowly bleed WHP down over 15 minutes to 500 psi WHP. Minimize surges while bleeding down WHP and during clean out to prevent nodes from getting displaced. 24.

Upon perforating, the well will be flowed to the flow station for clean-up and production. Should additional drawdown be necessary to unload the wells, it may be flowed to a tank for initial clean-up. The perforated intervals will be given in the subsequent report. Ail wireline work will be done through a 5000 psi WP BOP/Lubricator, tested to working pressure. The SSSV will be installed at the conclusion of the perforating and clean-up operation. -~u~sequ,,nt Work Beported AUG 1 ,? 1982 on Fora No./~ '~ 3~ Dated ~~~ g~aska 0il & Gao Cons.

Describe proposed program: ....... ARCO Alaska, Inc. proposed to directionally drill this well to 13,449' MD (9208' TVD) to- produce the Sadlerochit zone. Logs will be run across selected intervals. A 13 5/8" 5000 psi RSRRA BOP stack will be installed and tested to 5000 psi' The BOP equipment will be pressure tested each week and operationally tested each trip. A string of 5 1/2" 17#, L-80 tubing, packer and necessary provisions for subsurface safety equipment will be run. A non-freezing fluid will be left in all uncemented annuli within the permafrost beinterval'subn}i ttedThewhenPaCkerthe willwell beis toSetbeab°Veperforated.the Sadl erochi t.

Check and fill accumulator reservoir to proper level with hydraulic fluid. 2. Assure that accumulator pressure is 3000 psi with 1500 psi downstream of the regulator. 3. Observe time, then close all units simultane- ously and record the time and pressure remaining after all units are closed with charging pump off. 4. Record on IADC report. (The acceptable lower limit is 45 seconds closing time and 1200 psi remaining pressure. 13-5/8" BOP Stack Test 1. Fill BOP stack and manifold with a non-freezing liquid. 2. Check that all hold down screws are fully retracted. Mark running joint with predeter- mined plug seating depth. Run test plug on drill pipe and seat in wellhead. Run in lock down ~ screws. 3. Close 'annular preventer and chokes and bypass valves on manifold. 4. In each of the following tests, first hold a~250 psi low pressure test for a minimum of 3 minutes, then test at the high pressure. 5. Increase presure to 3000 psi and hold for a minimum of 3 minutes. Bleed pressure to zero. 6. Open annular preventer and close top set of pipe rams. Increase pressure to 5000 psi and hold for at least 3 minutes. Bleed pres- sure to zero. 7. Close valves directly upstream of chokes and open chokes. Increase pressure to 5000 psi & hold for at least 3 minutes. Bleed pressure to zero. 8. Open top set of pipe rams then close bottom set of pipe rams.'.Increase pressure to 5000 psi below the bottom set of pipe rams and hold for at least 3 minutes. · 9. Test remaining untested manifold valves (if any) with 5000 psi upstream of valve and zero pressure downstream. 10. Bleed pressure to zero. Open bottom set of pipe rams. 11. Back off running joint and pull out of hole. Close blind rams and test to 5000 psi for at least 3 minutes. 12.. Bleed pressure off all equipment. Open blind rams. Make sure manifold and tines are full of non-freezing liquid and all valves are set in drilling position. 13. Test standpipe valves to 5000 psi. 14. Test Kelly cocks and inside BOP to 5000 psi with Koomey pump. 15. Check operation of Degasser. 16. Record test information on blowout preventer test form. Sign and send to Drill)ng Super- visor. 17.
