Price Chair, Commissioner cc: Timothy Mayers, US Environmental Protection Agency, Region 10 Jim Regg and AOGCC Inspectors Oliver Stemicki, Hilcorp Well Integrity Engineer RECONSIDERATION AND APPEAL NOTICE As provided in AS 31.05.0S0(a), within 20 days after written notice of the entry of this order or decision, or such further time as the AOGCC grants for good cause shown, a person affected by it may file with the AOGCC an application for reconsideration of the matter determined by it. If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The AOGCC shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10 days is a denial ofreconsideration. If the AOGCC denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision denying reconsideration, UNLESS the denial is by inaction, in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the AOGCC grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the AOGCC, and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision on reconsideration. In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m. on the next day that does not fall on a weekend or state holiday.

Price Chair, Commissioner Alaska Oil and Gas Conservation Commission cc: Timothy Mayers, US Environmental Protection Agency, Region 10 Jim Regg and AOGCC Inspectors Oliver Stemicki, Hilcorp Well Integrity Engineer RECONSIDERATION AND APPEAL NOTICE As provided in AS 31.05.0S0(a), within 20 days after written notice of the entry of this order or decision, or such further time as the AOGCC grants for good cause shown, a person affected by it may file with the AOGCC an application for reconsideration of the matter determined by it. If the notice was mailed, then the period of time shall be 23 days. An application for reconsideration must set out the respect in which the order or decision is believed to be erroneous. The AOGCC shall grant or refuse the application for reconsideration in whole or in part within 10 days after it is filed. Failure to act on it within 10 days is a denial ofreconsideration. If the AOGCC denies reconsideration, upon denial, this order or decision and the denial of reconsideration are FINAL and may be appealed to superior court. The appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision denying reconsideration, UNLESS the denial is by inaction, in which case the appeal MUST be filed within 40 days after the date on which the application for reconsideration was filed. If the AOGCC grants an application for reconsideration, this order or decision does not become final. Rather, the order or decision on reconsideration will be the FINAL order or decision of the AOGCC, and it may be appealed to superior court. That appeal MUST be filed within 33 days after the date on which the AOGCC mails, OR 30 days if the AOGCC otherwise distributes, the order or decision on reconsideration. In computing a period of time above, the date of the event or default after which the designated period begins to run is not included in the period; the last day of the period is included, unless it falls on a weekend or state holiday, in which event the period runs until 5:00 p.m. on the next day that does not fall on a weekend or state holiday.

Intent as I communicated to Ryan Daniel on 1/20/12 was that weekly reporting was interim step while waiting for diagnostics (suspended due to extreme cold temps); TIO pressures should continue to be reported on monthly injection well integrity report for both wells until decision is made regarding need for Administrative Approval. PBU AGI -05 (PTD 1930020) Weekly reporting (see NGI -11) may be discontinued based on stabilization of annuli pressures that began last week of December 2011. This well can also be dropped from the monthly injection well integrity report at this time. PBU WGI -06 (PTD 190030) Existing Admin Approval (AIO 4E.006) should be canceled based on completion of workover. AOGCC will evaluate the need for a new Admin Approval for the shallow setting depth of packer associated with approved repair. PBU W -44 (PTD 1891000) Well may be remove• rom the monthly report based on passing MITIA (4/12 -11), no leak found with LDL (6/26/11), and stabilized annuli pressures exhibited during past 90 days while on injection..

During the monitor period the well has exhibited slow repressurization of the IA. The plan forward will be to leave the well on injection and run a leak detect log. If the leak is located it will be mitigated with a tubing patch. If a leak depth is not determined from the log, an AA will be pursued for future injection.

The Drilling fluid program will consist of an 8.5-9.5 ppg spud mud in the 17- 1/2" hole, a 9.0 - 9.7 ppg water base mud in the 12-1/4" hole and a 9.6 ppg water base mud in the 8-1/2" hole. Directionally drill 17-1/2" hole to 2763' MD (kick off at 1500') and cement 13-3/8" L-80 Buttress casing to surface. Install blowout prevention equipment consisting of 5000 psi W.P. pipe rams, blind rams, and annular preventer. Maximum possible bottomhole pressure is 4390 psi at 8800' TVDss based on original reservoir pressure. Maximum possible surface pressure is 3330 psi based on a gas column to surface from 8600' TVDss and an oil column to 8800' TVDss. Directionally drill 12-1/4" hole to the 9-5/8" casing point 10' below the Sag River Sandstone. Run 9-5/8" 47# L-80 NSCC casing to within 5' of 12-1/4" TD and cement using Class G cement around the 9-5/8" shoe. Directionally drill 8-1/2" hole to TD. Run 5 1/2" liner from TD to 250' inside 9- 5/8" casing shoe and cement using Class G cement. Clean out to 5 1/2" float equipment. Change over to 9.6 ppg. filtered NaCL completion fluid. Test casing and lap to 3000 psi. Perforate well with DP conveyed guns at 8SPF and 1500+ psi under balanced. Run 9-5/8" production packer on 7" tubing. Set packer 50' above top of liner. A subsurface safety valve with dual control lines will be placed 100' below base of permafrost. Install and test Xmas tree. Displace tubing to diesel. Set and test packer. Run CET/CBT/CCL-GR and GYRO after rig release. Fluids incidental to the drilling of a well will be pumped down the 9-5/8" x 13- 3/8" annulus of the well.
