I. Supervisor FROM: Bob Noble SUBJECT: Surface Abandonment Petroleum Inspector PBU Y-38 BPXA PTD #195-046 9/1/15: I arrived on location and met with BPX Rep. Dan Scarpella. Dan had told me that they had cut the well off at about 2 feet below pad grade and that looked about right. Note: Well was previously plugged on 11/14/14. The intent of this work was to cut the wellhead off below pad grade but not to the depth required below original tundra level which will be deferred until pad reclamation. I looked at the well and the 20-inch conductor and the 9 5/8-inch surface casing were full of hard cement. The 4-inch work string was 5 feet down. I ask him to top it off with cement. He also told me that the marker plate was in route for Anchorage. So he didn't have it there for me to inspect. I told Dan when he gets the 4-inch work string full of hard cement and the marker plate call for another inspection. Summary: I inspected the surface abandonment of PBU Y-38. Because the well is not cut off at the required depth per regulation it should be carried as a suspended well status.

The RWO operation performed the downhole scope of work in November 2014. Below is a summary of the job execution. MIRU. Killed well with seawater. ND tree. NU and tested BOPE with four preventers configured top down (annular, 7" fixed, blind shears, mud cross and 2-7/8" x 5" VBR's). Tested the VBR's to 3,500 psi and the annular to 3,500-psi. Pulled 4-W L-80 tubing down to cut above collapse. Performed a blind back-off of 4-W tubing. Swaged 7" casing to full ID. Dress tubing stub. RU EL to make a deep RCT cut at -9950'. Failed. RU EL again and perform successful jet cut. Ran overshot and pulled stub to surface. RU EL and ran TOC log to locate cement top and confirm no cement above surface casing shoe. Set 7" cement retainer at -9900'. Pressure tested retainer with Champs packer. Unable to establish injectivity below retainer. Spotted 1000 ft of cement on top. Tagged cement top. Notified AOGCC to witness. Mechanically cut & pulled 7" casing to surface 1 full joint above 9-5/8" surface casing shoe. Set CIBP. Ran 4-W kill string. ND BOPE, NU tree. Pumped cement to surface. Notify AOGCC to witness. RDMO. The wellhead is currently in the process of being removed. Once removed, the blue goo in the conductor will be removed and replaced with cement. The plan for this well is for the status to remain suspended with the wellhead removed about one foot below tundra, with a mechanically fastened marker plate a top the tubing/casing/cement.

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 7. · Chairman ~ J _ BY ORDER OF THE SSION dlf/Enclosures cc: Department of Fish & Game, Habitat Section w/o encl.
