Johnston 0 by CTD Engineer Date: April 5, 2012 Re: C-01 B Permit to Drill request Approval is requested for a permit to drill a CTD sidetrack from well C-01A. C-01A was a rotary sidetrack drilled in Feb 2003 and completed as a Zone 2A with 589' of perfs. The well came on strong and produced fulltime until late 2004 when it was shut-in for IAxOA communication. In Oct 2006 a RWO was completed, and the well produced fulltime until mid 2008 when it began cycling for high GOR. In July 2009, a CIBP was set to isolate production from the lateral, and 10' of Z2A & 10' of a Z2B lens were shot. Unfortunately, production did not change significantly and C-01A continued to cycle. On 1/12/2010 a WRP was set at 9,000' to isolate Z2A and only allow the Z2B lens to flow. The well flowed for -3 months • before cycling for high GOR. The WRP was pulled in Sept 2011 in hopes that Z2A had recharged during the -1.5 yr shut-in period. When POP'ed, the well tested above marginal GOR. C-01A is currently cycling with degrading production and ontime. Reason for Sidetrack The proposed plan for C-01 B is to drill a through tubing sidetrack with the Nordic 1 Coiled Tubing Drilling rig on or around June 1, 2012. The existing perforations of C-01A will be isolated by the liner cement job of C-01 B. The sidetrack, C-01 B, will exit the existing 4-1/2" • liner and kick off in Zone 2 and land above the 14N shale and HOT. 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. CTD Sidetrack Summary: Pre-Rig Work: (scheduled to begin May 1, 2012) 1. S Dummy GLV's (Done 1/9/2010) 2. F MIT-00A to 600 psi (Failed 4/1/2012) 3. F MIT-OA to 1,200 psi (Failed 4/1/2012) 4.

Generic GLV's Mud Program: • Well kill: 8.4 ppg brine. . • Milling/drilling: 8.6 ppg Geo Vis for milling window and drilling (provides a 686 psi overbalance to expected formation pressure). Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject. • • All Class I wastes will go to Pad 3 for disposal. • Hole size: 4.25" • Liner Program: • 3-1/4", 6.6#, L-80, TC-II Solid Liner (8,700' MD — 9,350' MD) • 2-7/8", 6.5#, L-80, STL Solid Liner (9,350' MD — 11,275' MD) • • A minimum of 23 bbls of 15.8 ppg cement will be used for liner cementing. (TOC 8,700' MD) • A cross over to a safety joint with a floor safety valve will be made up and ready for all l/ tubulars ran in hole. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3,500 psi. • The annular preventer will be tested to 250 psi and 3,500 psi. • A cross over to a safety joint with a floor safety valve will be made up and ready for all tubulars ran in hole. Directional • See attached directional plan. Maximum planned hole angle is 91°. • • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • • Distance to nearest property—24,500' • Distance to nearest well within pool —550' . Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • • Cased hole GR/CCUMCNL logs will be run. • Anti-Collision Failures • None Hazards • The maximum recorded H2S level on C-Pad was 38 ppm on well C-33A on 4/06/2011.• Reservoir Pressure • The reservoir pressure on C-01 B is expected to be 3,249 psi at 8,800' TVDSS. (7.1 ppg equivalent). • • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,369 psi. • • An EMW of 8.4 ppg for this well will provide 595 psi of overbalance to expected formation . pressure.
