Subject: UNDER EVALUATION: R-186 (PTD #1981190) Sustained IA Pressure due to TxIA Communication AI I, Well R-186 (PTD #1981190) has been found to have sustained casing pressure on the IA. The well broke maximum operating pressure limits on 4/13/09 with TIO pressures of SSV/2020/140 psi. A TIFL was conducted on 4/18/09 that failed due to fluid movement and pressure build up confirming TxIA communication.

We had intended to rewaiver the well for TxIA communication with a passing CMIT-TxIA on 11/29/05 indicating competent production casing. However, recent TIO pressure data and operator bleed records indicate that IAxOA communication still exists. With TxIAxOA communication the well is not a waiver candidate. We plan to cancel the existing waiver and reclassify well R-18B as a Trouble well. Please call me if you have any questions. Rob Mielke Well Integrity Engineer, BP Exploration, (Alaska) Inc.

I understood from our 8/31/05 meeting ("Well Integrity Update") that BP was no longer granting waivers for wells with TxIAxOA communication "due to only one mechanical barrier". I also understood from the meeting gas lifted wells with IAxOA communication would be secured as trouble wells. Please clarify.

This rig had just come out of 3 days of summer maintenance. The rig was ready to test when i arrived and we began immediately. All BOPE equipment was tested with no failures observed. The Gas detectors were calibrated and checked "OK" while I was there. The test time of 4 hours is not normal for this rig and was caused by a leaking pressure sensor line on the chart recorder. The rig was in fair shape as was the area surrounding it. SUMMARY: I witnessed the initial test of the BOPE on Nabors rig #2ES which is redrilling Arco well #DS 18-9 in the Prudhoe Bay Field. There were no failures observed. Test time 4 hours.

He had 'reused' an old form and overlooked the old information listed there. This permit, which was approved 07/10/98, was permitted as a producer, not an injector. How would you like us to proceed? ~, (I thought I would give you a chance to look it over before we talked...) Thanks! (907) 564-4628 Well Control Well control equipment consisting of 5000 psi w.p. pipe rams, blind rams, and annular preventer will be installed and is capable of handling maximum potential surface pressures. Diverter, BOPE and mud fluid system schematics on file with AOGCC. Bottom hole pressure is expected to be 3400psi @ 8750' TYDSS Maximum expected surface pressure at 8750' TVDSS is 2525psi (assuming gas column of 0. lpsi/ft) Hazards The main production target for this well is Zone 4. The main hazard for this well is drilling next to R-17 which has a frac in Zone 4. A total of 4 faults will also be crossed in the polygon which have a maxi- mum of 25'throw. Recent wells drilled in a nearby part of the field have not experienced severe losses, hence although preparations should be made to pump PCM, lost circulation is not expected to be a major problem because of faulting. _Sag River The Sag River can sometimes have very low reservoir pressure in this area. For this well the Sag is prognosed to have a 2500psi or 5.52ppg ElVlW. Lost circulation is expected to be a problem through the Sag, although the pad data sheet indicates that only one well (R-36i) has experienced ma- jor lost circulation in this production interval, most other drilling wells experiencing only minor losses. The area has some faults (which if present may be conductive), and this well does cross four 10-25' faults while in the target polygon, hence losses should be expected. Productive zone LCM will be em- ployed to combat this. On the R-36i well, returns were also not obtained while cementing the casing in place. Losses should be cured before attempting to run casing. Risk of differential sticking is expected based on offset wells, but should be mitigated by the use of Quikdriln drilling fluid which is solids free. Iyishak Differential sticking has occurred frequently in the Ivishak at 9183' TVD. Once the sticking occurs it is very strong and has created difficulty in freeing up the drillstring. On R-35A, the sticking was success- fully alleviated by pumping a 20bbl pill of Liquid Casing, OM Seal, and Barafibre and reducing pump rate to 5bpm (to reduce ECD). Note however that these wells were drilled using LSND mud; since this well will employ solids free Quikdriln, this should mitigate the risk of sticking. High torque has been re- ported on several wells in the production hole, hence some open hole lubrication may be required. The pa,d data sheet incorporates wells from R, F and J pad as the bottom hole location of these wells are all in the same area. Wells from all three pads have experienced problems with bridges, tight hole, differential stibking, and packing off while in the production interval. This has caused numerous incidents of stuck logs, casing, and drillstring. This is a high potential stuck pipe area - be alert while driling this interval and employ frequent reaming if any sign of unstable hole is seen. Disposal All cuttings should be hauled to the ball mill at CC-2A for disposal. Haul all drilling and completion fluids and other Class I1 wastes to CC-2A for injection. Haul all Class I wastes to Pad 3 for disposal. 1 6 ' 998 Oil & Cx commi i0n Well Control Well control equipment consisting of 5000 psi w.p. pipe rams, installed and is capable of handling maximum potential surface system schematics on file with AOGCC.
