To: Tom Maunder Petroleum Engineer Alaska Oil & Gas Conservation Commission From: Greg Sarber CTD Engineer Obp Date: March 12, 2007 Re: X-30A Sundry Approval Sundry approval is requested to abandon perforations on well X-3D. X-30 is currently shut in for T x IA communication. Well X-30 began production in May 1995 as a horizontal producer in Zone 4 periphery. Original production was over 3700 BOPD, but the well decreased to 400 BOPD by late 1997. Because there was no injection support in the area, the pressure fell from 3625 psi in 5/95 to 3362 psi in 8/98. Offset injectors X-33 and X-36 began water injection in mid 1998, and the production decline reduced over the next year. An acid stimulation on 5/14/00 had little effect on production. X-30 had good MI responses to both offset injectors. X-30 was on production full time until a Gas Lift Survey on 12/2/03 identified a tubing leak at 8,455' MD, A caliper log on 3/31/04 showed the tubing in poor condition with 41 joints having 40-85% wall loss and 10 joints with 85%+ wall loss and possibly multiple holes. The majority of the damaged tubing is located between GLM's #3 & 4, but other portions of the tubing are not in good shape. The well passed a No Flow Test (NFT) on 4/16/04, and was allowed to produce on a waiver. An MITOA failed on 4/19/04, so an OA down squeeze was performed on 5/27/04. The follow up MITOA on 5/31/04 passed. Well X-30 failed an NFT-IA on 4/20/05, and it was shut in for flow to surface status. A CMIT TxlA to 3500 psi and an MITOA to 2000 psi passed 12/10/06; confirming production casing and surface casing integrity. The well remains shut in, ./ The well is scheduled for a work over to replace the existing 4-1/2" L-80 production tubing with 4-1/2" chrome tubing. A stacker packer completion will be made. (See attached schematic). Immediately following the work over a coil tubing sidetrack will then be made by performing what is essentially a toe drill out of the existing parent well bore. (A whipstock will be used at TD to avoid milling the float equipment with coil tubing.) The purpose of the sidetrack will be to add reserves from the targeted area in the periphery of the water flood, The intent is to retain access to the current drainage area reserves and access incremental reserves from an extension of the well bore to the southeast to evaluate the down dip limits of the reservoir. A portion of the perforations in the parent well bore will be abandoned by the sidetrack liner cement job. The cement job on the ./sidetrack liner is planned to come up to 12,500' MD in the parent well bore (Inclination 89,9 deg). Perforations in the parent well above this depth are intended to be preserved, Perforations below this depth are intended to be abandoned by the liner cement job, The plan is to leave 520' of open perforations in the parent well bore above the cement top depth while abandoning 410' below the cement top.

You then will perform the sidetrack operation. You can describe in the new well plan that some of the existing perforations will be plugged with the new liner cement. My read is since no perforations from the original well are planned to remain below the sidetrack point, that the well name will become X-30A. If your cement winds up high on the liner job, I don't think that is an issue since you will just re-shoot. Regardless, holes will exist where holes were. Hope this answers your question. Call or message back. Tom Maunder, PE AOGCC ti~ MAR 0 9 2007 Sarber, Greg J wrote, On 3/512007 4:26 PM: Dear Tom, I have a question for you about whether a sundry approval is needed. I am working on well þJ X-30. This is a horizontal production well completed in Ivishak zone 4. It currently has badly corroded tubing causing T x IA communication. It has also failed an NFT-IA, so is secured with a tubing tail plug and the well shut in. We plan to move Nordic 2 onto this well sometime this summer. A workover will be performed changing the 4-1/2" L-80 production tubing to 4-1/2" chrome, using a stacker packer completion. After we do the workover, we plan to set a whipstock near TD in the production liner, and drill a coil tubing sidetrack. The cement job on the sidetrack liner is planned to come up to 12,500' MD (Inclination 89.9 deg). Perforations in the parent well above this depth are intended to be preserved. Perforations below this depth are intended to be abondoned by the liner cement job. The plan is to leave 520' of open perforations in the parent well bore above the cement depth while abondoning 410' below the cement top. The inclination of the top perforation in the well is 59 deg. My question for you is, is a sundry needed to abondon the perforations in the parent well below the cement top, if there remain existing perforations open in the parent well in the same zone (zone 4). This is a horizontal well, so predicting the cement top using current coil tubing technology is not exact. We have designed the job so that the cement top is at a relative "high" in the parent well. However annular spaces are small, and a slight difference in cement volumes drastically effects the height of the cement top. What happens if the cement job does not go off as planned, and we lose all the perforations above 12,500'? A sketch showing the well geometry is attached to this email to help explain the situation. 3/612007 9:31 AM ..

Merv Liddelow, BPX representative in charge of the testing, performed the tests in a safe and proficient manner. Of the 26 wells tested, 3 failures were witnessed. Well X-14A's SSV failed to close and well X-19B's pilot was frozen and the SSV failed to close. Mr. Liddelow indicated to me on 12/10/00 that these items have been corrected and successfully re-tested. The AOGCC test reports are attached for reference. I conducted 26 well house inspections Concurrent with the SVS tests. A slight crude oil leak was noted on a wellhead flange of well X-19B. Mr. Liddelow indicated he would have this item addressed. No other exceptions were noted. SUMMARY: I witnessed SVS tests and conducted well house inspections on BPX's X Pad. 26 wells, 53 components tested, 3 failures. 26 well houses inspected.

The permit to drill does not exempt you from obtaining additional permits required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permitting determinations are made. Blowout prevention equipment (BOPE) must be tested in accordance with 20 AAC 25.035. Sufficient notice (approximately 24 hours) of the BOPE test performed before drilling below the surface casing shoe must be given so that a representative of the Commission may witness the test. Notice may be given by contacting the Commission petroleum field inspector on the North Slope pager at 659-3607.

The well will further appraise the X-Pad/DS-14 ,~lqery area of the Prudhoe Bay Unit targeting Zone 4 in the Sadlerochit. ]'he well is planned as follows: Hole Size 13-1/2" Hole 9-7/8" Hole 6-3/4" Hole Completion: Casing Size 20" Conductor (pre-drilled) 10-3/4" Surface Casing 7-5/8" Intermediate Casing Pilot Hole to identify OWC 4-1/2" Slotted Liner 4-1/2" L-80 Tubing. Casing Point 10' TVD above SV3 Covering all Kingak and set @ top Shublick 150' MD past OOWC HAW to 20' TVD above OWC Drilling Hazards Surface Close Approach Well Shut-ins The adjacent surface well, X-14, is 34' (within 60') of X-30 and should be shut-in during rig moves. The adjacent surface well, X-13, is 75' (greater than 60') and does not need to be shut in during rig moves. This includes bleeding off all pressured lines. X-14 is currently flowing 1,070 bopd and X- 13 is flowing 600 bopd. Please coordinate with the Production Group to minimize this shut-in oil. Drilling Close Approach Well Shut-ins There are no drilling close approach wells if the survey program and tolerance lines are strictly followed. Pore Pressure Expectations CRETACEOUS: The 'recommended minimum mud weight before drilling the Cretaceous injection interval between 4,323' md and 6,716' md is 9.5 ppg. The highest estimated formation pressure in the Cretaceous injection interval is a 9.2 ppg EMW @ 5936' md (5065' tvd rkb). Adding a 100 psi trip margin, the minimum mud weight calculates to be 9.5 ppg EMW. In the intermediate hole section, the Cretaceous interval defines the need for the highest mud weight. Although the Kingak has a lower pore pressure, the mud weight needed for the Cretaceous generally helps hole stability problems with the Kingak. SAG RIVER: No formation pressures were available in the Sag River sand. Out of the last two wells drilled on X pad in 1994 one, X-31, was able to drill the Sag River with 9.0 ppg. In the other well, X-20, the intermediate hole was drilled through the Sag River formation with 10.2 ppg' fluid. X-28 & X-35 wells drilled the production hole with 8.9 ppg. SADLEROCHIT: The formation pressure at 8800' sstvd is 3,560 psi or 7.7 ppg EMW. See the minimum mud weight curve for better details as to pressure expectations/mud weight requirements. Cretaceous Injection Since most injection into the Cretaceous interval is over 2 miles away, little risk of seawater influx is expected while drilling the 9-7/8" hole. The last two wells that were drilled from X pad, X-20 and X- 30, confirmed this due to the 9.5 ppg MW used to drill this interval. Lost Circulation There are several possible situations where circulation could be lost during this well. The most likely case will be while drilling just above the Sag River. There is a fault (20' to 40' throw) expected in the 9-7/8" hole near the bottom of the Kingak at 11,142' md (8770' tvd rkb). With this possible loss zone above the Sag River formation, the rig crew should be alert to losses in the wellbore and be ready to accurately measure loss rates if they occur.

X-20 and X-30, TD'd the intermediate hole section with ~,g fluid and had no losses. On the other hand, X-28 & X-35, which also had mud weights of . ppg, both lost mud while running intermediate casing. X-20 experienced losses in the production interval while using 9.0 ppg fluid. The losses were stopped, and a pilot hole completed successfully. The horizontal section of the hole experienced losses at _+4 bph all throughout this section. Surface Casing Shoe Kick Tolerance Kick tolerance for the casing shoe is calculated as 48 bbls of influx assuming a swabbed gas influx at TD along planned directional path with 9.5 ppg MW, 9.5 ppg reservoir pore pressure, and a 12.5 ppg shoe test.
