This permit supersedes and replaces the permit previously issued for this well dated February 7, 2014. This permit to drill does not exempt you from obtaining additional permits or an approval required by law from other governmental agencies and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the AOGCC reserves the right to withdraw the permit in the event it was erroneously issued. Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the AOGCC specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a AOGCC order, or the terms and conditions of this permit may result in the revocation or suspension of the permit.

Starting December 1987 the well was used as a disposal. The well was later converted into a Sag River producer; however, well F-19 was then placed out of service due to a corroded injection line. Integrity problems developed in 1994 which necessitated a rig workover(RWO)and this timing coincided with a major Sag River recompletion and fracture stimulation campaign so the RWO was performed with the intent of making F-19 a Sag River producer. Despite having the 4th largest frac in the campaign of 14 wells that were recompleted in the Sag River in the mid-1990's, F-19 was not a successful Sag producer. F-19 was sidetracked in 2009 Reason for P&A/RST: The subsequent F-19A well is uncompetitive due to high GOR. The well was considered for coil sidetracking but well integrity, proximity to gas, and the risk of isolating the new well from fault related gas in the parent well makes a RST a better choice. • Reason for Revision to PTD: This well was originally considered for coil sidetrack. A sundry and PTD was submitted for this purpose. However, integrity screening indicated slow IA x OA communication when on gas lift, so CST option was decided against. Additionally, a rotary sidetrack shows a better chance for isolating from the parent location, gave us a better chance of getting a good cement job, set us up better for future GSO, and let us access deeper structure and stay away from potential gas production. An in zone rotary sidetrack option was also considered; however, we need to change the intermediate casing to gas tight threads and the in zone kick off would require pulling the 7"x 5"flexlock liner hanger which was risky and added cost. Also considered completing the well with swell packer/sliding sleeve completion, but decided against this due to the risk of gas in the area.

Well Control / Reservoir Pressures: A. Intermediate Hole: Sag River is expected to be a 5.95 ppg EMW. II. Lost Circulation A. The Sag River has a lower than average pore pressure and fracture gradient in this area. Due to the lower frac gradient there is an increased risk of lost circulation during Drilling, Casing, and Cementing of the intermediate hole. B. Almost all Sag River wells have experienced lost circulation in the Production Hole section. Both faults to be crossed have had medium lost circulation potential Ill. Faults A. Fault 1 will be crossed at -12,617' MD. It is estimated to be 10-15' down thrown to the south. This fault crossing has been characterized as having medium lost circulation potential. B.
