The well is planned to be sidetracked to a new bottom hole location as a conventional horizontal producer. Any wells with surface locations within 30' (Well head/Rig separation) of the subject will need to be shut in for rig move activities. · Notify the field AOGCC representative with intent to plug and abandon. Pre-Riq Work: E-31 Objective: Plugback horizontal, slotted liner in preparation for rig side-track. Top of Cement Bottom of Cement: 4 1/2" liner ID Capacity: Cement Column Cement Volume: Cement into perfs: 1. See wellbore schematic attached. 2. Load and Kill IA and tubing. Perform injectivity test to verify ability to pump into the well. 3. Plug & abandon 4 ½", slotted liner w/15.8 ppg Class G cement from 100' above top perforation( 12597') to bottom perf(13393'). Place 5 bbls minimum behind pipe into perf's. Estimated cement volume is: 12597 ft. 13393 ft. 3.96 in. 0.015 bbl/ft 796 ft. 12 bbls 5 bbls 4. Overdisplace to perfs with Seawater and diesel for freeze protection 5. Minimum TOC is 100' above top perforation. Max TOC is at the sidetrack depth of 8400'. 6. MIRU S/L. Drift/Tag TOC test, and document top of cement per AOGCC requirements. 7. Test the IA (casing annulus) to 3500 psi against the packer. Hold 1000 psi on the tubing to prevent from collapsing the tubing. 8. MIRU E/L unit. RIH with jet cutter and sever tubing below anticipated side-track depth. A CIBP & whipstock will be set after the drilling rig removes the tubing. Jet cutter is acceptable as this tubing will not be fished. Note the depths of the GLM's in the 5 Y2" tbg string. Circulate clean seawater around IA and tubing. 9. Test the casing mandrel pack-off to 5000 psi and service lock down studs by backing out and re-torquing one at a time. Test the tubing hanger pack-off to 5000 psi and service each LDS. 10. Check with the 7ES Rig Supervisor regarding rig timing and determine if freeze protection to diesel will be required. Bleed tubing and annuli pressures to zero. Set a BPV in the tubing hanger and test from below to 3500 psi. Secure well with 0 psi on tubing and annulus. 11. Remove the well house and flow lines. Level the pad and dig out the cellar. Please provide total well preparation cost on the hand over form.

I. Supervisor DATE: December 8, 1993 FII,E NO: eirhlhad.doc FROM: Doug Amos', 'Dou~ ~ SUBJECT: Petroleum Inspector Diverter Test- Nabors 28E BPX, PBU R-35 Prudhoe Oil Pool PTD No. 93-161 Wednesday, December 8, 1993: I traveled to BPX's PBU R-35 to witnessed the function test of Nabors 28E Diverter System.. The Diverter Systems Inspection Report is attached for reference. The function test began at 1:00 p.m. and went well. I found the rig to be in good condition. All components functioned properly. However, the Manually Operated Knife Valve on the right side vent line outside the rig substructure does constitute a potential danger and basically defeats the fail safe design intended by AOGCC Diverter Regulations 20 ACC 25.035(b)(1). As stated on the attached Diverter Systems Inspection Report only the starboard 10 3/4" hydraulically operated Knife Valve opens simultaneously when the Annular Preventer is closed. Should the need arise to divert to the port vent line, that 10 3/4" hydraulically operated Knife Valve can be opened with the Kill Line HCR Valve control signal. To stop the flow through the starboard vent line, rig personnel must manually close the Knife Valve outside the rig substructure. To further complicate the system, if the manually operated Knife Valve is in the closed position when the diverter is actuated, the entire diverter system is defeated. Jerry Herring and ! have discussed this problem area with both Nabors and BPX supervisors in the past (Jerry's Report 9/28/93 eirkixac.doc) and to date no corrections have been instituted. I brought this item to the attention of Nabors Toolpusher Lavern Linder and BPX representative Dave Bumgardner during this inspection. Dave contacted his supervisor, John Wilboughby and Lavern contacted his supervisor, Richard Larkin. ! was assured that a correction would be made, to the valve configuration, before drilling the next well with this rig. I would suggest that the inspection staff stay aware of this problem, and conduct additional Diverter Systems Inspections to ensure the problem is corrected in a timely manner. Summary: Witnessed the diverter test on BPX PBU R-35 at Nabors 28E.

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. David W.
