MEMORANDUM State of Alaska Alaska Oil and Gas conservation Commission TO: THRU: FROM: Julie Heusser, ~' Commissioner Tom Maunder, P. I. Supervisor DATE: April 16, 2001 Jeff Jones, Petroleum Inspector SUBJECT: Safety Valve Tests Niakuk Field BPX PBU / Niakuk Pad April 16, 2.00!: I traveled to the Niakuk Field to witness Safety Valve System tests on BPX's oil producing wells. Well house inspections were also conducted. The testing went well with Ron White as the BPX representative in charge of testing. 12 wells were tested with two failures witnessed. The pilot on NK-12A tripped below 50% of the separator pressure and was replaced and passed a retest. The $SV on NK-62 failed to hold D.P. and was stroked and passed a retest. I inspected 12 well houses and all were in order with no exceptions noted. The AOGCC test forms are attached for reference. SUMMARY;. I witnessed SVS tests on 12 oil producing wells in BPX's Niakuk _ Field. 12 wells tested, 36 components. 2 failures witnessed, 5.5% failure-rate. 12 well houses inspected, no exceptions noted.

The well was shut in due to high water cut in August of 1999. The well is planned to be sidetracked to a new bottom hole location as a conventional producer targeti.nthg the Kuparuk reservoir. The sidetrack is currently scheduled for Doyon 14 beginning around February 25t , after the completion of Niakuk 12B. The pre-rig work for this sidetrack is planned to begin as soon as the attached Application for Sundry is approved. Pre-Riq Work: * Notify the field AOGCC representative with intent to plug and abandon * 1. RIH with CTU, through tubing, to top of fill in 5 Y2" liner. Perform a cement P&A using 15.8 ppg class 'G' cement with adequate cement volume to fill the 5 ½" liner from top of fill to a minimum of 100' into the tubing tail. Squeeze 5 additional bbls into the perforations, t, ~ ~-$ -- t"'t~\ ,,-,4~,~ ,~,_,.,,~ ¢,. NOTE: The AOGCC has requested on prior sidetracks exiting above the reservoir, that the top of cement be brought up into the tubing tail -100', therefore the minimum top of cement should be 15,616'. Top of cement may extend further up into the tubing as long as it does not interfere with the upcoming tubing cutting operations. 2. Tag and document top of cement and drift tubing for upcoming tubing cut. 3. Liquid pack the tubing and 9-5/8" x 4-1/2" annulus to surface. Test the integrity of the cement plug and casing by simultaneously pressure testing both the tubing and annulus to 3000 psi for 30 minutes. Increase tubing pressure prior to the 9-5/8" annulus to avoid possibility of tubing collapse. 4. Cut the 4 W', 12.6#, tubing at approximately 13,100' MD. Displace the well to kill weight fluid by circulating down the tubing through the tubing cut. Continue to circulate until kill weight fluid returns to surface. Freeze protect top 2200' MD with diesel. 5. Pressure test the casing pack off for 30 minutes. If 9 5/8" casing was set on emergency slips, test the 9 5/8" pack off to 3,800 psi, which is 80% of the casing collapse pressure. If the 9 5/8" casing was landed on a mandrel hanger, test the pack off to 5,000 psi. Test the tubing hanger seals to 5000 psi for 30 minutes. 6. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 1000 psi. Secure well. 7. Remove the well house and flowlines. If necessary, level the pad. Please provide total well preparation cost on the handover form. Ri.q Operations: 1. MIRU Doyon 14. 2. Circulate out freeze protection and displace well to kill weight fluid. Set TWC & test from below. 3. Nipple down tree. Nipple up and test BOPE. 4. Pull and lay down 4-1/2" tubing from E-line cut and above. 5. MU 9 5/8" window milling assembly and RIH to top of tubing stub. POOH. 6. Set CIBP at -13,000' MD. To avoid cutting a casing collar, set the BP 2' - 3' above a collar. 7. RIH with 9~5/8" Baker bottom-trip anchor whipstock assembly. Orient whipstock as necessary and set. Mill window in 9-5/8" casing. Perform FIT test. POOH 8. RIH with 8 ½" drilling assembly to whipstock. Kick-off and drill through Kuparak Sand to Top Kingak dropping angle to -60 degrees inclination. Drill 100' of rat hole in the Kingak. 9. Spot liner running pill. POOH w/DP. Run and cement a 4 1/5", 12.6 # production liner. Displace cement w/viscosified brine perf pill followed by fresh water spacer and mud. Release from liner and circulate out excess cement and displace well to kill weight fluid. POOH. After cement has gained compressive strength, test the casing and liner from the landing collar to surface to 3000 psi for 30 minutes 10. Drill pipe convey perforate Kuparak sands @ 6JSPF. 11. Install 4-1/2", 12.6# L80 new or used tubing completion. 12. Drop ball/rod & set packer and test the tubing to 3500 psi and annulus to 3000 psi for 30 minutes. 13. Nipple down the BOPE. Nipple up and test the tree to 5000 psi. 14. Freeze protect the well to -2200' and secure the well. 15. Rig down and move off. Post-Ri_q Work: 1. Pull the ball and rod / RHC plug from below the new production packer. Install gas lift valves.

The AOGCC BOP Test Report is attached for reference. The drillsite at Niakuk is quite small and is shared with production and construction so the area is quite congested. The rig has installed audible alarms to alert the other groups, as to any emergencies or incidents. The rig and its area was well laid out and quite clean, all access lanes were open.

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 Nodh Slope pager at 659-3607.
