Fluid flow has seemed to stop or become so slow it is not recording increased volumes any longer, all returns seem to be fresh water. The casing pressure (gas lift pressure) is running 400 psi higher than the Gas Lift Engineer has seen in the past(suspected a sticky gas lift valve), so we are going to "Rocking" the well this afternoon, during the shut-in and pressure buildup we will again place a manwatch on the well. It is expected that this shut-in will only be for 4-6 hours, the well will then be brought on again. After it stabilizes I plan to return to three hour manned visits. regards, Bruce Kevin Yeager / Bruce W.

The tubing tail is above the 7" liner top, In 19~4 it was discovered that the setting ports at the bott~)m of the BeT 3Id packer leaked @ 8849' md. The liner is in communication with the tubing above the tailpipe profile, In 1/97 a sidetrack completion was performed. A 7"x 9 5/8" tieback string with a Baker packer was run. The tubing was also changed out to 4 I/~o L-80 with BTC - mod threads. On August 10, 1999 c~ude oil/water mixture was discovered to be slightly weeping out of/and around the conduclor pipe. The casing hangers and tubing hangem were tested and found to have gcmd integrity, The well was tmmedtamly shut in and all pressures were bleed off the annulus's. A pump open plug was set to further isolate the tubing from possible problems reaching surface, The inlermedlate and ouler annulus were tlul~l packed and pressure tested on August 12. The intermediate annulus was tested to 1170 psi and held pressure resulting in a pass pressure test, The Outer annulus test indicated communication With the conductor pipe at .3 Opm @ 100 psi pump pressure. The following day the outer annulus had hot dieSel pumped down it to establish an injectivity rate. While pumping down 1he outer annulus, oily/water appeared to surface in the cellar, This was noticeable after approximately I bbl being pumped. Established an injectivity rate of 1,37 Opm ~ 800 psi. A cement down squeeze job was performed on the outer annulua with 24 0bls of Aslite cement, This is a quick setting up ~m~ent. The foil~vlng day a pressure test was performed on the cement squeeze and the pressure test failed, Established an injeotivity mis of. 3 Opm @ 300 psi, Armther outer annulus cement clown squeeze was performed using 5.5 bbls of 15.7 13pg class G cement. During this operation we could see some small bubbles coming up between the outer annulus anti the conductor pipe, A N2 pressure test Ihs following day concluded that the squeeze was holding pressure at 800 psi to nitrogen. · . J · The well was subsequently put back on production at 15:00 hfs and the following morning, the pad operator noticed at 02:00 during his reads that oil had discharged into and on to the sides of the welthouse. The discharge was not in progress at the time of his readir~gs and had happened sometime between whe~ the well was put on productian and his readings. The well was immediately shut in and the pre.ute were bled off once again. The field AOGCC inspector, Mr. Chuck $cheve was notified of the spill/status of the well, and th~ environmental group was instrucled to clean up the spill that morning. After the inside of the wellhouse was cleaned up the well had the live gas lift valves pulled and dummy valves rein, also a plug was run in the tallplpe to insure additional integrity while diagnoslic worl< was performed, The flowline and tubing were freeze protected with me~hanol at this time. On Sept, 19, additional leak hunt diagnostic work was performed and witnessed by the AOGCC Inspector. This consisted of pressure testing the outer annulus again only this time wilh liquid pressure. The pressure test of the outer annulus failed at 800 psi and a slight amount of fluid entered the cellar via the conduotor pipe route again. Samples were collected anti taken to the lab. We again pressure tested the intermediate annulus and during this test noticed dear water/oil coming Into the cellar. We left 1540 psi on the intermediate annulus overnight lo monitor. The following day the intermediate annulus still had 1410 Indlcateding that we had good integrity on this annulus, We then, with the concurrence et the ^OGCC inspector put the lift gas back on while I<eepin9 the wing valve closed to monitor pressures on the inner annulus and tubing conducting a 24 hour manwatch of this operation. Slight seepage was observed until 13:30 on that day but subsequent the tollowing additional 24 hours of this no visible signs of seepage wa~ noticed. The inner annulus gas lift pressure was at 2000 psi and the shut in wellhead pressure was 1940 psi, The next step was for slicktine to pull the bottom gas lift dummy valve so we could pressure test both 1he inner annulus and tubing for leaks. The pressure lest on the tubing and inner annulus was conducted to 2500 psi. During the teat no discharge of fluids in the (;oiler was observed. Tubing/inner annulus pressure test lost a total of 90 psi. No pressure inomase on the outer annulus was observed, The test was witnessed my Mr. John Spalding with 1he AOGCC, SENT g¥:l~ EXPLORATI6N PE ;10- ~.--MM ; 20:l;J ; Current Status: The well remains shut In and freeze Protected. There is a plug in the tailpipe, The botlom gas lift station is OlOen, There has been no discharge of any fluid. The casing and tubing hangers have been testetl and are good. We have integrity on the intermediate annulus proven and witnessed by a fluid pressure test. We have integrity on the tubing and inner annulus proven and witnessed by a fluid pressure test. The outer annulus has failed the fluid pressure test. The following pregrarn outlines the outer annulus leak repair to fix this well once and for ail. Procedure; ! 10. 11. 12. 1, Ensure safe out of the tubing and iriner annulus by being fluid packed. 2, Bleed down intermediate and outer annulus of all pressures. 3.

A ripple of clear fluid is visable. It seems this is caused by vibration fi.om the well producing. The volume in the catch basin seems to be completely stable. Well vitals are stable. Neither the outter annulus or middle annulus have built any pressure. Both annulus have low pressure test gauges installed. The catch basin has a fix measuring md installed. Proposed Plan forward: Continue production of the well, return the well to normal status. Have the field operators return it to their normal monitoring. No action will happen until AOGCC concurs it is prudent. Status Report E-Mail to AOGCC on 10/24/99 and 10/26/99, with verbal phone call to B. Wondzell on 10/26/99. Verbal phone call to Tom Maunder AOGCC on status 11/3/99. Plan on having verbal phone discussion with John Spaulding 11/7/99. (JS is in transit this morning) : . N-20 Broach Subject: N-20 Broach Date: Mon, 20 Sep 1999 20:51:26 -0800 From: Chuck Schev¢ <chuck_schcve~admin.state.ak.us> Organization: State of Alaska, Dept o£ Admin, AOGCC To: Blair Wondzell <blair_wondzell~admin. state.ak.us> ~nternal grp Hi Blair Here is what we know so far. At 2AM 9-18 the drill site operator found that well N-20 had broached in the cellar and spayed the walls of the well house with crude oil (BP estimated 10 gal) it was probably more but not a large volume. Ken Smith with BP notified me of the event at aproximatley noon on the 18th. I went to location where clean up operations were under way. The well had been winged in and gas lift supply shut down, no futher fluid movment evident. A plug was set in the tubing tail and operations suspended until the next day. 9-19 I returned to location with Kevin Yeager. A pump truck was rigged up to the outer annulus (13 3/8 X 9 5/8) and an attempt to pressure test failed (broke down at 800psi and circulated up the conductor to the cellar at 40 psi)returns appeared to be mostly water. This annulus is believed to have a hole at 30' and two attempts to cement had been completed in recent weeks, the second was completed 8-28-99 and held a 1000 psi pressure test. The pump truck was then rigged up to the intermediate annulus (9 5/8 X 7) and pressured up to 1540 psi. A small amount of fluid (water) surfaced in the cellar while pressuring up. I agreed to holding this pressure test over night. After 18 hours the pressure on the intermediate annulus=1400 psi. 9-20 intermediate annulus bled to 400 psi. With the plug still set in the tail pipe and the wing valve still closed gas lift pressure ,1850 psi, was applied to the inner annulus (7'' X 4 1/2 ) . A small volume of thick crude oil surfaced in the cellar while pressuring this annulus then flow stopped. A sample of this oil taken to lab no results as yet. No futher leaks evident. 1 of 1 9/21/99 7:36 AM PERMIT DATA AOGCC Individual Well Geological Materials Inventory T DATA PLUS Page: 1 Date: 01/21/99 RUN RECVD 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 96-184 CHEM CTTR ~/10100-10200 DGR/RES-TVD ~/~8529- 8974 DSR/RES-~ J~/93 72 - 12584 CNTD ~F~9001 - 10121 7641 ~HL~ C~D V956 ~'-6,8,9.11-14 SPERRY GR/RES PERF ~I~i825-12000 PEX- CN/LDT L~ 50 - 12559 PEX- CN ~-9350 - 12559 PEX-AIT ~9350 - 12559 PEX-MCFL ~-9350-12559 BHP ~'~350-12559 PEX- SST~ ~9350 - 12580 7769 ~CHL~ PEX-AIT/BHC o- ov Are dry ditch samples required? yes n~__o~ And received?

ORIGINAL MEMORANDIJM TO: THRU: State of Alaska Alaska Oil and Gas Conservation Commission DATE: December 10, 1996 Blair Wondzell, P. I. Supervisor -- ~--'i---'~ ~ '~ ~ · FROM: Bobby Foster,?.~2-~ SUBJECT: Petroleum Inspector FILE NO: AINILJDD.doc BOPE Test- Nabors 18E BPX - PBU - N-20A PTD # 96-0184 Tuesday, December 10., 1996: i traveled this date to Nabors rig 18E to witness the upcoming BOPE test on BPX's PBU well N-20A. I arrived at the location at 11:30 AM and the test began at 12:30 PM. Prior to the test I spoke with Mike Whitely, BPX rep., and he informed that he wanted to test using a 5' joint of drill pipe rather than a joint of 5.5" tubing which was the size tubing in the well. ! told Mike that ! would accept a test of the choke manifold and associated equipment, then they would have to remove the 5" drill pipe test joint and test the upper rams and the annular preventer. Mike had a concern about collapsing the 5" tubing by pressuring to 5,000 psig with no pressure on the tubing. ! told Mike that since the collapse pressure of the 5' tubing was about 6,100 +- psig ! didn't think that the would have any problem but since the well was plugged i would accept a 3,500 psig test of the top rams and annular preventer until the tubing had been pulled but another test would be required when the 3.5" rams were installed to began the sidetrack operation. The crew began by testing the upper pipe rams and the last 2 valves in the choke manifold. A valve stem packing leaked on a valve upstream of the chokes. The valve was repaired and the test began again. Then a connection leaked on the stack and it was decided to isolate the choke manifold and test the choke manifold. The isolation valve leaked and was repaired. As the crew pressured up again the bonnet gasket began to leak on the same valve. This was repaired and as pressure was brought up the stem packing began to leak on the valve which had been repaired earlier, it was then decided to isolate the choke manifold, pull the test joint and test the blind / shear rams. The rams leaked and a new element was installed on the block and re-assembled. The ram leaked again and the tooipusher told me that he didn't have any more but he had a set of regular blind rams he would install. It was then discovered that the cross over subs for the tubing hanger to the 5.5" tubing were not the right thread.

RIH with coiled tubing to 10,130 MD - 100' MD below the bottom perforation (bottom perforation at 10,030' MD). Lay a cement plug from 10,130' to 9,676' MD. This will leave cement about 300' above the top perforation (top perforation at 9,976' MD). NOTE: Top of cement must be to at least 9,876' MD to comply with State regulations of cement being 100' MD above perforations. 3. With an AOGCC representative on location to witness the operation, R/U slickline and tag the top of the cement to verify cement top is at least at 9,676' MD. 4. RIH and cut the 5-1/2" L-80 tubing with a chemical cutter in the middle of a full joint of tubing above the production packer at approximately 8,790' MD. 5. Displace the tubing and wellbore to 8.5 ppg seawater. 6. Freeze protect top 2,200' MD with diesel. 7. Bleed tubing and annuli pressures to zero. 8. Set BPV in the tubing hanger and test from below to 1,000 psi. Secure well. 9. Remove the well house and flowlines. If necessary, level the pad and dig out the cellar. Please provide total well preparation cost on the handover form. RicJ Operations 1. MIRU drilling rig. 2. Pull BPV. Circulate out freeze protection from inner and outer annuli and recover for future use. Test 9-5/8" mandrel packoff to 5000 psi. 3. Install a TWC and test from below to 1000 psi. N/D the production tree. 4. N/U BOP. Test BOP to 250/5000 psi against TWC. Test annular preventer to 250/2500 psi. Remove 'I'VVC. Send adapter flange and tree to DSM for inspection and repair. 5. Pull and lay down the 5-1/2" tubing. (Tubing should be jet cut at 8790' MD. Check the location and exact depth of the cut on production handover form) Inspect for NORM. Label tubing as it is laid down with well name and joint number. Install thread protectors on pipe which upon visual inspection appears to be re-usable. If tubing is salvageable, send tubing to Tuboscpoe for inspection. N-20A Permit Information RECEIVED NOV lgg Aia~k~ 0il & ~ Oon.~. ~0mmi~i~n Page 4 . . . , 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. RIH with overshot assembly. Engage 20' seal assembly and anchor latch at ~8821' MD. Rotate latch out of BOT production packer. RIH with PRT assembly. Mill up BOT packer at ~ 8845' MD. CBU - beware of any trapped gas below the packer. POOH with packer and tailpipe assembly - BOT packer has a millout extension, therefore, we should be able to mill and fish the packer with the PRT. Replace 9-5/8" mandrel packoff. ND BOPE. Remove tubing head. Install new 2-Step casing spool and tubing head. NU BOPE. Test wellhead and BOPE to 5000 psi. RIH with 7" tieback polish mill and 9-5/8" casing scraper - tieback sleeve is 7.50" ID and 6' long. Polish tieback sleeve at -9058' MD. Circulate well clean.

Pump freeze protect fluid, seawater, spacer and cement to cement liner in place. Drop wiper plug without latch and bump plug. Slack off liner tieback seal stem assembly into liner tieback sleeve and weight set packer in tieback assembly. RIH with bridge plug. Set bridge plug at approximately 9389' MD. This will place the bridge plug 3' below a 7" casing collar at 9386'. The whipstock will begin to mill out the casing 30' above the bridge plug. Shut in well and test casing to 3500 psi for 30 minutes to ensure casing integrity. P/U and RIH slowly with a Baker Anchor/Whipstock assembly with MWD. MWD will be used to align the whipstock to 30° left of highside. The bottom trip anchor will be set by slacking off on the bridge plug. Continue RIH 40' above bridge plug. At this time start pumps and pulse MWD to check whipstock face orientation. Using MWD, align whipstock face to 45° left of high side making sure all excess torque is worked out of string. When proper orientation is achieved slack off with pumps watching for undesired whipstock rotation until bridge plug is tagged. At this point slack off 10 klbs to shear run-in pins on anchor. After pins are sheared pick up 10 klbs over to assure anchor is set. Slack of _+45 klbs to shear whipstock from mill. Once sheared from the whipstock, displace well with Sheardril-n drilling fluid. Begin cutting window using only enough WOB and RPM to cut window as smoothly as possible. Continue milling casing and try to make at least 22' of formation, approximately 38' total of milling and drilling from the top of the whipstock. This will allow the full-sized watermelon mill to pass through the window all the way down to the bottom of the window effectively reaming the sidetracked interval.
