C -42 was drilled in April 1993 as a horizontal producer (bonzai completion) targeting Zone 1 A & 1B. A RWO in Oct 1995 replaced the tubing to address TxIA communication, and the liner lap was squeezed in 1996 to eliminate communication between the Sag River and the IA. Otherwise, the well produced fulltime until late 1997 when it began cycling. The well continued to cycle for the next 5 years with —50% on time until it developed TxIA communication. A tubing leak was identified at 7182' MD and was patched with an Eclipse patch from 7169 -7204' in Nov 2002. The well was brought back online but continued to cycle until it developed TxIA communication again in May 2006. The leaking Eclipse patch was pulled and replaced with a 35' Baker KB patch in Aug 2007. The well was brought back online but cycled poorly with declining oil rates. The well is currently shut -in for high GOR. REASON FOR SIDETRACK C -42 is no longer a competitive producer, and there are no remaining wellwork options. The proposed sidetrack will access an undrained target in the northern portion of C -pad. The proposed plan for C -42A is to drill a through tubing sidetrack with the SLB/Nordic 1 Coiled Tubing Drilling rig on or around May 1, 2011. The existing 4 -1/2" slotted liner will be plugged with cement down squeeze past whipstock and primary cement job. The sidetrack, C -42A, will exit the existing 7" liner and kick off in Ivishak Zone 2A and land in Zone 1 A. The following describes work - planned and is submitted as an attachment to Form 10 -403. A schematic diagram of the proposed sidetrack is attached for reference. Co cu . 6 o l2 1t401 res0.

I. Supervisor O~lo%-C) I~ THRU: March 23, 2001 FROM: Jeff Jones, SUBJECT: Petroleum Inspector Safety Valve Tests PBF/PBU C Pad March 23, 2001: I traveled to Prudhoe Bay Field to witness Safety Valve System tests on BPX's C Pad. Well house inspections were also conducted. Merv Liddelow was the BPX representative in charge of testing, and performed the tests in a professional manner. Twenty-one wells on C-Pad were tested with five failures witnessed. The SSV on well C-04A tripped below 50% of the separator psi, the SSV on well C-07A failed to hold D/P, the pilot on well C-19B was frozen, the pilot on well C-20B failed to trip and the SSV failed to hold DiP. Mr. Liddeiow indicated to me that all failures were repaired within 24 hours. I inspected 21 well houses and noted leaking wing valves on wells C-03A, C-13A and C-19B. A hydraulic fluid leak on the SSV control line of well C-05 and a slight crude oil leak from the SSV on well C-25A were also noted. Mr. Liddelow indicated he would have these items corrected. The AOGCC test forms are attached for reference. SUMMARY: I witnessed the SVS tests on twenty-one oil producing wells on C Pad in the Prudhoe Bay Field. 21 wells tested 42 components, $ failures witnessed, and 11.9% failure rate. 21 well houses inspected.

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. ..... S i~c_ere lY ,~-~..
