Drilling & Wells Coiled Tubing Drilling Team Attention: Tom Maunder Petroleum Engineer Subject: Well Y-37 CTD Sidetrack Prep Production well Y-37 is to be sidetracked to a new reservoir location using coiled tubing drilling. The following summarizes the procedure required to prep the well for drilling and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed completion is attached. Gas lift v/v's dummied off & inner annulus fluid packed Test wellhead seal integrity to 5,000psi. Mechanical integrity of IA tested with 2,000psi pressure test. Fluid pack & test mechanical Integrity of OA to 1,000psi Tree's master, wing & swab valves to be tested to 4,000psi. Drift to whipstock setting depth with 20' x 3.625" dummy assembly 4W' x 5W' whipstock to be run & set at 10,650'md, (8,787' tvd) P&A open perforations, above & below the whipstock using 10 bbls of cement. Whipstock setting and P&A operations are scheduled to commence 11m Mar & CTD operations are expected to follow on 18th Mar 2002. Y-37a will emerge from a window cut in 5W' liner at 10,650'. The 3sA'' OH sidetrack -2,240' long will be drilled with 23A'' CT through ZA of the Ivishak reservoir. It will be completed with a Bonsai style, (solid 33/16'' x solid/slotted 27A'') liner run from TD back into the 4~A'' tbg. Cement will be squeezed behind pipe from where the solid 2~A'' liner ends back into the 5~" liner. Production will come in through the 27A'' slotted section. Using the following targets for the Bonsai completion: window = 10,650'md, TD = 13,088'md, TOL = 10,400', Float & diverter = 12,300' and TOC = 10,500', then approx. 14bbls of cement will be pumped for hydraulic isolation.

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.
