The Nordic rig 1 was executing approved drilling program and permit to drill for 05-35AL2 when wellbore stability problems at the window forced a decision to plug back and start over. 05-35A was completed in September 2008. The A bore came on at marginal rates with minimal WC, and minimal gas. The well stayed around these production values until July-2011 when a slotted liner lateral was added to the 05-35A in an attempt to make it a more economical well to produce. The well had a few flush tests then settled out right back at the prior rates of 05-35A. the L1 lateral was drilled in very low net to gross sand, and the production trends agree with this. Rig Work: (Began on January 26, 2013) 1. MIRU and test BOPE to 250 psi low and 3,500 psi high. 2. Bull head kill the well with 1% 8.4 ppg KCI. 3. Set 4-'/2" TT flow through packer whipstock at -10,800' MD. (Below the new gas contact point). 4. Mill 3.80" window at 10,800' and 10' of rat hole. Swap the well to PowerVis. p4 ,4 5. Drill Build/Lateral: 4.25" OH, lost lateral and is now PB1 This lateral was lost due to well bore stability at the window. • 6. Run and set 45 KB Packer whipstock at 10,485' MD ' � a_ 7. Drill Build/Lateral: 4.25" OH, 2,750' (12 deg/100 planned) with resistivity to a TD of 13,235' • 8. Run 3-1/2" X 3-1/4" X 2-7/8" L-80 Cemented liner leaving TOL at -10,285' MD. 6. Pump primary cement leaving TOC at 10,285' MD, 31 bbls of 15.8 ppg liner cmt planned. . 7. Perform liner cleanout with mill, motor and MCNUGR/CCL log. 8. Test liner lap to 2,400 psi. iv L w P11) 9. Perforate liner per asset instructions (-1,000'). 3 , ( S 10. Freeze protect well to 2500' TVD 11.Set BPV, RDMO. Post-Rig Work: 1. Re-install wellhouse, flow line and pull BPV 2. Set liner top packer if needed with slickline & test to 2,400 psi 3. Set Gas lift valves 4. Test separator. Mud Program: • Well kill: 8.4 p g brine. • Milling/drillin : 8.5pg PowerVis for milling window and drilling (613 psi over-balance). Disposal: • All Class I & II non-hazardous and RCRA-exempt drilling and completion fluids will go to GNI at DS 4 or Pad 3 at DS 6. • Fluids >1% hydrocarbons or flammables must go to Pad 3. • Fluids >15% solids by volume must go to GNI. • Fluids with solids that will not pass through 1/4" screen must go to GNI. • Fluids with PH >11 m go to GNI.

(TOC 10,610' MD) • The primary barrier for this operation: a minimum EMW of 8.4 ppg. • A X-over shall be made up to a safety joint including a TIW valve for all 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. Directional • See attached directional plan. Maximum planned hole angle is 90° . • Inclination at kick off point is 68° • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. . • Distance to nearest property— 32,578'. - • Distance to nearest well within pool — 355' from 05-36A. Logging • MWD directional, Gamma Ray and Resistivity will be run over all of the open hole section. • Cased hole GR/CCL/MCNL logs will be run. Perforating: 9 • SWS 2", 6 spf, pert guns, 1-1/4" CSH work string, & 2-3/8" PH6 • The primary barrier for this operation: a minimum EMW of 8.4 ppg. . • A X-over shall be made up to a safety joint including a TIW valve for all tubulars ran in hole.

Status: Producer • 05-36APB1 212' (ctr—ctr distance) Fails at 11,975' MD. Status: Plugged and abandoned. Hazards • Drill Site 5 is not considered an H2S pad. • Most recent H2S level on 05-35A is 22 ppm recorded on 1/21/2012. • The lost circulation risk in 05-35AL2 is considered to be low with no fault crossing p lanned. Reservoir Pressure • The reservoir pressure on 05-35AL2 is expected to be 3,276 psi at 8,800' TVDSS. (7.16 ppg equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2,396 psi. • An EMW of 4 ppg for this well will provide 567 psi over-balance to the reservoir.
