A sundry (303 -149) was approved 5/28/03 allowing the well to continue injecting water only and requiring annual LLRTs. From what I see in the record, no communication /leak was ever documented with the LLRTs. There is correspondance in December 2005 to cancel the sundry and return the well to normal (non- restricted) service. A 404 cancelling the sundry was submitted 12/29/05. A successful MIT IA was accomplished 12/14/09. Based on the file information, it appears there is no regulatory restriction to beginning MI injection into the well. Your plan to perform the 4000 psi MIT is appropriate. I presume the well integrity coordinators and operators will be monitoring the well's performance as the MI injection commences. Call or message with any questions. Tom Maunder, PE AOGCC From: Brown, Don L.

We are looking at swapping this well back to MI and found a note /correspondance with your name on it dated back to 2002 about this well not going back to MI as a recommendation due to slow TxIA communication. Historically, this well has had MI back in 1996 and 1998 and the GLM #1 was leaking and the DGLV was changed out in 2005 which may have been the source of the TxIA communication in the early 2000's. Before the well is swapped back to MI, we need to complete the MIT -IA to 4000 psi and set the MCX. Do you see any reason why we couldn't attempt to inject MI back into this injector?

Box 196612 Anchorage, AK 99519-6612 RE: Application for Sundry Approval, Well Y -18 PTD 183-029, Sundry No. 304-278 Dear Mr. WaITen: The Alaska Oil and Gas Conservation Commission hereby denies the subject application by BP Exploration (Alaska) Inc. (""BPXA "), to stimulate well Y -18, dated July 14, 2004. Well Y -18 exhibits T x IA x OA pressure communication which is indicative of leakage across two of the well's tubulars. No action to correct the pressure communication is proposed in your subject application. Western Operating Area underground fluid injection is permitted under Commission Area Injection Order ('~AIO") No.3. Rule 7 of AIO 3 requires that, in case of any pres- sure communication or leakage in an injection \vell, the operator cease injection, notify the Commission, and obtain approval for corrective action. Under AIO 3 Rule 9, BPXA may request administrative relief from this ruling. Such a request to continue operating well Y -18 must demonstrate to the Commission's satisfac- tion that sound engineering practices are maintained. Very truly yours, (]JIM Dan Seamount.

EST. Cost: $ 110 M 500 lOR Attached is a procedure for "Propellant Fracturing Stimulation" of GOWFI injector Y-18i. Pre-work includes a CT FCD and slickline drift to. .§nable wireline access to the targeted interval. The FCD is preceded by a bullhead SBG to save coil time and reduce the risk of plugging the current injectivity. The objective of the stimulation will be to minimize future plugging, so the PFS treatment should proceed even if post FCD injectivity is high. 1 2 3 4 F C S E Bullhead SBG Fill clean out TO tag with TEL.

Per operators' notes, IA has alreadv exceeded maximum pressure when ~ returninç¡ to injection on 11/21/03. I ' Y -18i has had difficulty injecting at the roughly 10 MBO required to control GDR in the H-pad offset producers. A 2002 Fill Cleanout/Mud acid stimulation established PWI injectivity of 8 - 10 MBO for - 1 month before the well partially plugged off. Poor injectivity is thought to be the result of high near wellbore tortuosity, so Y -18i could be a good candidate for PFS stimulation. (The sidetrack option has encountered some opposition.) The fill cleanout incorporates SBG to maintain access to existing injectivity at a reasonable cost. Mud acid is not recommended, as it will complicate evaluation of the PFS treatment and significantly increase cost.

'1 " oJ~ Objective: Clean tubing for caliper survey. Try to improve injectivity. Background: . Cold water breakdown with 1600 bbls seawater in 1994 appears to have provided a sustained injectivity improvement. . Slow T x IA communication, rapid IA x DA communication. Well injecting on waiver /' with 2500 psi max pressure on IAlDA. . IA increased about 300 psi/hour during MIT-T on 5/8/03. . Safety/Integrity note: Suspect T x IA communication is one-way. IAlDA remains above tubing pressure when WHP drops, and LLRT-T is greater than LLRT-IA. WATCH FOR THERMAL EXPANSION while pumping hot SSG, after completion of cold water breakdown, and when returning to PWI. SBG / Cold Water Breakdown: 1. Prepare 260 bbls SSG dispersant per the following standard procedure: / a. Ensure all personnel are familiar with SSG safety procedures, and have required PPE. b. Ensure SSG concentrate is circulated for 15 minutes in the 30,000 gal tank before loading onto the vac truck. c. Load 44 bbls (1856 gallons) SSG concentrate onto the vac truck. d. Load 216 bbls 160 F water from the Hot Water Plant onto the vac truck. e. Mix with vac truck blending paddle~ while in transit to location. 2. SI well. MIRU hot oil pump truck. Due to flowline corrosion, please rig up to the tree cap. Monitor S-riser during job to ensure that flowline is not pressured above 2000 psi. Rig up bleed trailer and PE triplex to IA. 3. Pump 260 bbls SSG into the well at 3 - 4 bpm, 2000 psi max. Freeze protect surface lines as required. Note: SBG is hotter than PW. Watch for annulus thermal /' expansion. Bleed IAlOA so they are no higher than injection pressure. (Objective is to keep differential less than that experienced during normal ops.) 4. Allow to soak for three hours. 5. Displace with 195 bbls of 160 F water, 2000 psi max. (Shmoo will disperse more easily in warm water.) Monitor and bleed annuli as in step 3. 6. Allow to soak for an additional three hours. , ( ( 7. Pump cool ( - 90 F) seawater breakdown as follows. Maximum pump pressure , should be 3000 psi, but may need to be reduced to 2500 psi if T x IA communication '\ is rapid. Maximum IA/OA pressure is 2500 psi. Minimum IA pressure should be 1500 psi to minimize differential across the tubing of unknown condition. Record rates and pressures when staging rates and every 100 bbls. a. Pump 560 bbls seawater at 2.5 bpm. b. Pump 560 bbls seawater at 5 bpm. c. Pump 560 bbls seawater at 8 bpm* (Or max rate of 5 bpm or better if 8 bpm would require additional equipment). 8. LWSI until caliper can be run. Freeze protect well and flowline as required. Bleed IA/OA to approximately SIWHP to allow for potential pressure increase as the wellbore warms back. (Formation will remain cool since that's where the water leaked off.) 9. IA/OA may pressure up due to thermal effects. (Suspect one-way leak from T to IA.) Ensure manpower is available to monitor IA/OA when SI after breakdown and when returning to PWI. $ ( ( .' .

When the water injction into Y -18 was stopped on January 8, 2003 the tubing pressure went on a vacuum. We had originally planned to set a TTP once injection had ceased, but since there is no pressure on the tubing we would like to change our plan and not set the TTP. Our plan forward is to set a BPV and continue with the wellhead diagnostics (i.e. re- energizing the wellhead seals, etc.) in order to repair the IA x OA communication. As always, please let me know if you have any questions or disagree with our diagnostics plan. We will keep you informed of our progress and seek approval prior to returning the well to injection.

We bled the OA on 12/26/02, and the pressure has increased approximately 150 psi /day. Due to the OA valve configuration on the wellhead, we have not yet been able to perform a MIT -OA or establish a LLR to confirm the communication path. However, based on the repressurization rate, it appears that we now have IAxOA communication, likely through the wellhead. Our current plan is to set a TTP and secure the well; we will then troubleshoot the IC pack -offs and perform a MIT -OA. Should we re- establish tubing and /or production casing integrity, we will contact you before beginning any type of injection. If you have any additional questions, please call John Cubbon or Joe Anders at 659 -5102. Thanks.

According to the history of Y-18, it is indicated that communication while on MI was suspected at the end of October. The well passed a normal MIT shortly thereafter, however it has now failed the normal MITIA with a leak rate less than 1 gpm. This is similar to P-03A which I sent a note on a little bit ago. It appears that the available information does indicate a tubing leak to fluid. You are requesting permission to do further diagnostics which based on your time frame should be completed by the end of the year. Please plan to get back to us at that time. If the communication still exists at that time, plan to submit the necessary paperwork in the first week of the new year. Please call with any questions.

Your diagnostics plan sounds appropriate. Restricting the well to water is also appropriate. It will be interesting to see if there is any communication to water. I have a few questions.

In order to test the wells integrity, we performed a MITIA on 11/04/02 to 2500 psi, which successfully passed. After several more days of monitoring it was noticed that the T x IA pressures continued to track. On 11/13/02 we bled the IA from 2000 psi to 200 psi and monitored the build-up rate.

Our proposed plan of action is as follows:l. Continue injection and restrict the well to water only injection (No MI) while diagnostics are being performed.2. Perform a PPPOT-T on the tubing hanger to determine if it is the source of communication.3. Re-MITIA to 3000 psi to see if a LLR can be established.4. Based on diagnostic testing, make a recommendation to repair for continued WAG injection or seek approval from the AOGCC for continued water only injection with an approved monitoring program.
