History and current status: G-16 was originally completed in 1981. A 1988 RWO installed a straddle to isolate the original gas cap perforations. Loss of tubing and production casing integrity necessitated another RWO in 2003 in which a 7" scab liner was run and the tubing was replaced. The well was first sidetracked with CTD in 2009. G-16A was eventually shut-in for high GOR. The well has exhausted wellwork options and has no remaining value and is ready for sidetrack. Proposed plan: G-16B will exit from well G-16A by the Nordic 2 Coiled Tubing Drilling rig on or around March 1, 2015. The G-16B sidetrack will perform a dual-string exit through the existing 3-1/2" tubing and 7" liner. Kick-off will occur in the Sag River formation and target Zone 1B reserves. The proposed sidetrack is a —2,850' horizontal Ivishak Zone 1B producer which will access a —35 acre reserves target southwest of G- Pad. The lateral will be completed with a 2-3/8" L-80 liner which will be cemented and perforated. This Sundry covers plugging the existing G-16A perforations via the G-16B liner cement lob or liner top packer set post-rig (alternate plug placement per 20 AAC 25.112(i)). The following describes work planned and is submitted as an attachment to Form 10-403. A schematic diagram of the proposed sidetrack is attached for reference.

Those wells that are not re-drilled immediately are identified every 6 months and assigned a current status of"Suspended." Step Task Responsible 1 The initial reviewer will check to ensure that the "Plug for Redrill" box in the Patricia or Steve / upper left corner of Form 10-403 is checked. If the "Abandon" or "Suspend" boxes are also checked, cross out that erroneous entry and initial it on both copies of the Form 10-403 (AOGCC's and operator's copies). 2 If the "Abandon" box is checked in Box 15 (Well Status after proposed Patricia or Steve work) the initial reviewer will cross out that erroneous entry and initial it on J both copies of the Form 10-403 (AOGCC's and operator's copies). Instead, then check the "Suspended" box and initial that change. Guy or Victoria The drilling engineers will serve as quality control for steps 1 and 2. (QC) 3 When the Stat Tech receives a Form 10-403 with a check in the "Plug for Jenni Redrill" box, she will enter the Typ_Work code "IPBRD" into the History tab for the well in RBDMS. This code automatically generates a comment in the well history that states "Intent: Plug for Redrill." 4 When the Stat Tech receives any Form 10-407, she will check the History tab Jenni in RBDMS for the "Intent: Plug for Redrill" code (IPBRD). If present and there is no evidence that a subsequent re-drill has been COMPLETED, the Stat Tech will assign a status of SUSPENDED to the well bore in RBDMS no matter what status is listed on the 10-407. The Stat Tech will also change the status on the 10-407 form to SUSPENDED, and date and initial this change. If the Stat Tech does not see the "Intent: Plug for Redrill" comment or code, she will enter the status listed on the Form 10-407 into RBDMS. 5 When the Form 10-407 for the redrill is received, the Stat Tech will change Jenni the original well's status from SUSPENDED to ABANDONED. 6 The first week of every January and July, the Stat Tech and one of the Jenni Geologists will check the "Well by Type Work Outstanding" user query in Patricia or Steve RBDMS to ensure that all of the Plug for Redrill wells have been handled properly. At this same time, they will also review the list of suspended wells for accuracy. • ~ Image Project Well History File Cover Page XHVZE This page identifies those items that were not scanned during the initial production scanning phase.

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, Gerald Murphy, at 659 -5102.

Well History Well G-16 was completed in October 1981, and perforated into the gas cap as part of a gas equity study. Two unsuccessful sodium silicate squeezes were performed in an attempt to seal off the gas cap perforations. The well had a RWO in November 1987 and was completed with a straddle to isolate the gas cap perforations. The well struggled to produce after the workover despite two mud acid jobs. Add perfs had to be shot in early 1991 to make the well a steady producer. In 1993, perforations were added in a 26P lens. The lens perforation was successful and the well made additional oil with only a slightly higher GOR. At some point in the early 1990s the straddle that was isolating the gas cap equity perforations began leaking. The leak was confirmed with a log in April 2006. The leak was at a collar so a patch was place over it and GOR dropped from 20,000 to 5,000 scf/bbl. Soon after the patch was run, the high GOR resurfaced and it was determined that the 9-5/8" packer that made up the top of the straddle was leaking. In May 1996, tubing punch holes were shot near the bottom of the straddle and circulation was established up the IA through the leaky packer. Cement was circulated into the straddle while taking returns up the IA and the gas was shutoff. A loss of tubing integrity was noted in 2002. A RWO package was issued for a simple tubing swap to replace corroded 4-1/2" L-80 tubing with 4-1/2" 13Cr tubing. During the pre-rig prep work, the well failed CMIT-TxIA with an immeasurable liquid leak rate, this was the first indication that the production casing might have lost integrity. The rig moved onto the well in September 2003, pulled tubing and then confirmed the casing leak with a retrievable packer and pressure testing. A 7" liner was run to cover the casing leak and then the 4-1/2" 13Cr tubing was run to complete the workover. After the workover, considerable effort went into fishing a plug from the 2-7/8" tubing tailpipe. In the end, tubing punches were shot above the fish so the well could be produced. The geometry of the packer bore, millout extension, tailpipe and fish prevented a chemical cut or jet cut from being performed to drop the tailpipe into the rat hole. In February 2008, G-16 was selected to field trial the Schlumberger Abrasi-Jet tool to cutoff the tailpipe and restore access to the 7" liner. The Abrasi-Jet tool suffered a mechanical failure downhole so an under-reamer contingency was exercised and it successfully cutoff the tailpipe. This has restored access to the 7" and set the well up for a tiny tools sidetrack. The well is currently a low on time cycle well. It produces at a higher than marginal GOR, and has little remaining reserves in it's existing drainage pattern. Reason for PTD Request -Your approval is requested to drill a coil sidetrack lateral from the G-16 parent well. This lateral will relocate the drainage pattern to Zone 1 B Ivishak. There is also a significant oil pad in Zn 2A overlying ZN1 B in this area. i zone has fair to good permeability and ~Id provide good recharge to the well from above. 6. 7. 8. "T1~~ s 9. 10.
