This is the second attempt at the target area; Y-35 was junked and abandoned during prep work for a CT sidetrack in March 1999./The following background was provided to the AOGCC in April 1999 as part of the Report of Sundrv Well Operations (stating that the well was plugged and suspended pending evaluation): On March 5, 1999 the service coil unit pumped ~,S/~bls cement to abandon existing perforations. Squeeze pressure was not achieved and an ~'t~mpt was made to wash out cement above the whipstock in preparation for a second cem~t squeeze. This process resulted in getting-cement above the service coil noz~z~;//The enCdCes~lt was c,,emented in c.o,,il with the nozzle at 7995 ft;, Service coil was cut at 6737 leaving/125.~, ft of 1 tubing. The drilling coil unit moved onto Y-35 on March 10, 1999 to fish the stuck service coil. After failing to jar the fish free, 2 7/8" wash pipe with an external cutter was run. This assembly successfully swallowed 662' of the I ~" coil but was unsuccessful in cutting the 1 ~" coil to permit recovery. On 3/16/99 the fishing operation was suspended. The original l~,~.~" service coil fish together with the 2 7/8" wash pipe fishing assembly has been left in the weft. The cement pumped by service coil has effectively sealed the perforations and there is no communication to the reservoir. A 2500-psi combo tubing x IA pressure test on 12/3/02 confirmed that the cement plug is effectively isolating the reservoir. The proposed sidetrack will return the well to production with better position within the reservoir to capture remaining reserves associated with attic oil trapped east of a fault in upper zone 4B. Y-35A is planned as a 5843' sidetrack (1408' in Ivishak reservoir). This target will establish an additional take point on the west side of the A-16A injection pattern, 1750' north of Y-32L1, a successful 2001 lateral producer. Y-35A is planned as a slotted liner completion. The Y-35A sidetrack is currently scheduled for Nabors 2ES beginning around New Years day 2003, after completing the H-02A sidetrack. The pre-rig work for this sidetrack will be priority scheduled immediately after the Application for Sundry is approved. Scope Pre-Riq Work: 1.

Perforation abandonment was to be performed by service coil prior to arrival of the coil drilling unit. In the process of pumping abandonment cement the service coil became stuck inside tubing. The following is a description of the events and the current status of Y-35. A description of the fish is given on the attached wellbore schematic. On March 5, 1999 the service coil unit pumped 26.5 bbls cement to abandon existing perforations. Squeeze pressure was not achieved and an attempt was made to wash out cement above the whipstock in preparation for a second cement squeeze. This process resulted in getting cement above the service coil nozzle. The end result was cemented in coil with the nozzle at 7995 ft. Service coil was cut at 6737' leaving 1258 ft of 1%" coil with a 3" nozzle stuck within the 4.5" tubing. The drilling coil unit moved onto Y-35 on March 10, 1999 to fish the stuck service coil. After failing to jar the fish free, 2 7/8" wash pipe with an external cutter was run. This assembly successfully swallowed 662' of the 1%" coil but was unsuccessful in cutting the 1%" coil to permit recovery. On 3/16/99 the fishing operation was suspended. The original 1%" service coil fish together with the 2 7/8" wash pipe fishing assembly has been left in the well. The cement pumped by service coil has effectively sealed the perforations and there is no communication to the reservoir. BPX is requesting that Y-35 be placed on suspended status pending evaluation of further fishing and well utilization options. The subsequent form required is a 10-407, however, due to problems encountered, this well was not sidetracked and a 10-404 was thought to be more appropriate. Mr. Wondzell was contacted by T. Hubble and he concurred.

The following summarizes the procedure required to prepare Y-35 for sidetracking and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack .completion is attached. 1. A tubing integrity test will be performed. 2. Tubing and liner will be drifted with a 3.625" OD drift. 3. A mechanical whipstock will be set in the 5 1/2" liner at approx. 11,030', or 47 ft above the top perforation. 4. Service coil will be used to downsqueeze approx. 25 bbls cement past the whipstock to abandon existing perfs. A squeeze pressure of 1500 psi will be achieved and witnessed by AOGCC prior to washing out cement above the whipstock. 5. The window will be milled with either service coil or drilling,coil. A flowline will be used for returns if the milling is done with-a service coil. Form 10-401 will be obtained prior to milling.
