A surface plug may not be required at this time if the wells are otherwise mechanically sound. However,these wells must be included in the development of a P&A plan for suspended wells with no future utility that must be approved through the Commission by 12/31/16.

I need a bit of clarification on what we need to do to change them over. • 03-05, PTD#176057 o Failed RWO in 1991-Tubing pulled, EZSV with cement cap set in the 9.625" casing. For some reason this well did not have a PT in 1991 when the rig moved off of it. I assume that if we apply for a suspension we will need to get a PT. o No future utility • G-03A, PTD# 197070 o RWO suspended on 10/25/06 when the rig found holes in the production casing between 5262-5291'. A EZSV was set at 5096' and a 4.5" kill string was run to 5015'. o PT passed to 3500 psi on 10/24/06 1 • • o No future utility • Y-08A, PTD# 188056 o This well has a P&A sundry open (314-595), but we are unable to close it out because we have not been able to get a PT on the cement job that was performed in late 2014. TOC was tagged at 8597', but there is a tubing leak at 4390' and a production casing leak at 2700'. o No future utility Please advise on what is required for each of these to get them moving towards SU status.

The corrosion inhibitor is engineered to prevent water from entering the annular space and causing external corrosion that could result in a surface casing leak to atmosphere. The attached spreadsheet represents the well name, API and PTD numbers, top of cement depth prior to filling and volumes of corrosion inhibitor used in each conductor. As per previous agreement with the AOGCC, this letter and spreadsheet serve as notification that the treatments took place and meet the requirements of form 10 -404, Report of Sundry Operations. If you require any additional information, please contact me or my alternate, Jerry Murphy, at 659 -5102. Sincerely, Torin Roschinger BPXA, Well Integrity Coordinator • • .

At 1:00 p.m. RIH with open-ended drill pipe and tagged the plug with 30,000 pounds of drill string weight at 10,897' (ft). This gave a cement plug of 23' above the liner lap. POH and prepare to set second plug on top of first. Thursday, June 16, 1988: At 1:30 p.m. after waiting on cement for 16 hfS,' RIH and~tagged the second liner lap plug with 20,000 pounds of drill string weight at 10,833'. This was 74' above the liner lap, because there was not the required 100' of cement. I contacted Mike Minder and was given his approval to accept this plug and to let the operator continue with their operations. Attached is a copy of the Wellbore schematic for SAPC PBU Y-8A well.

The permit to drill does not indemnify you from the probable need to obtain additional permits required by law from other governmental agencies prior to commencing operations at the well site. To aid us'in scheduling field work, please notify this office 24 hours prior to commencing installation of the blowout prevention equipment so that a representative of the Commission may be present to witness testing of the equipment before the surface casing'shoe is drilled. Where a diverter system is required, please also notify this office 24 hours prior to commencing equipment installation so that the Commission may witness testing before drilling below the shoe of the conductor pipe.

This new bottom-hole location (well) will be called Y-8A. Well Y-8A will be a horizontal drainhole with a proposed bottom-hole location close to the old Y-8 location. From the plan view, the new wellbore (Y-8A) will be displaced approximately 300 feet from the old wellbore (Y-8) and from the section view, the new wellbore will drop below and cross beside the old wellbore (see attached directional map). The closest well other than Y-8 is the PLAGHM State #1 well which is 1600 feet to west of the proposed well Y-8A (see attached circles map). Based on these facts, there will be no close approaches with other wellbores in the area. A maximum allowable distance will be maintained from the old wellbore of Y-8.
