However, while pressures were being bled after the MIT, fluid returns were seen in the conductor. An MIT-OA was performed to evaluate and fluids were returned to surface from the conductor during the MIT-OA confirming a surface casing leak. The well is reclassified as Not Operable and should remain shut in until repairs are conducted and integrity is restored.

Anticipated Surface Pressure:2420 psi (Based on 0.1 psi/ft. gas gradient) Last SI WHP: 2175 psi (Taken on 01/09/2012) Min ID:1.78” ID – deployment sleeve @ 10,700’ MD Brief Well Summary: x H-04A was CTD sidetracked in 2011. A surface casing leak materialized in 2012. An MITOA to 1200 psi failed with the pressure rapidly dropping to ~300 psi and fluid returns observed in the conductor. x The well currently has one-way IA x OA communication (from the IA to the OA) but the OA pressure does not communicate to the IA. There is also a small one-way tubing leak from the tubing to the IA. x The OA was cemented to surface during well construction in 1971. Objective: Execute an OA downsqueeze with cement and/or Well Lock. Achieve a passing CMIT-TxIA. POP the well Under-Evaluation for up to 60 days to validate that the SC leak is fixed and establish production rates to decide if the tubing leak is economic to repair. Procedure: DHD 1. Displace fluid level in OA with nitrogen. 2. Strap TOC in the OA. Slickline 3. Set Flowsleeve in GLM @ 3018’ MD. DHD 4. Verify that the IA and tubing are fluid-packed. 5. Top off the OA with cement and/or Well Lock per the volume of OA established by strapping TOC. 6. Squeeze the OA to 1200 psi with Microfine cement and/or Well Lock to seal off the SC leak. Fullbore/DHD 7. Circulate a bottoms-up down the production tubing, through the flowsleeve in Sta #2, with returns from the IA to flush any cement or Well Lock that may have squeezed into the IA. 8. FP tubing and IA. DHD 9. Pump Green-Stick packing into the IC void. Fullbore/DHD 10. CMIT-TxIA to 2500 psi. Verify no communication to the OA. 30 minute charted test. - mgr OA Downsqueeze H-04B PTD: 211-085 Slickline 11. Run GLVs 12. Pull WRP @ 9580’ MD. Operations/DHD 13. POP the well Under-Evaluation through hardline to an adjacent well. 14. Keep a cellar-watch for the first 24-hours to verify no fluid from the conductor. 15. Re-squeeze the OA with cement or Well Lock if the SC leak is not fixed. 16. Keep the well online for up to 60 days to verify the SC leak is fixed and test the well. 17. SI well after 60 days and evaluate economics of LDL and repairing tubing leak. Attachments: 1. Wellbore Schematic 2. Sundry Change Form 18. 12 hour cellar check for SC leak during 60 day flow under evaluation period. - mgr OA Downsqueeze H-04B PTD: 211-085 Wellbore Schematic OA Downsqueeze H-04B PTD: 211-085 Changes to Approved Sundry Procedure Date: Subject: Sundry #: Any modifications to an approved sundry will be documented and approved below.

The well is reclassified as Not Operable and should remain shut in until repairs are conducted and integrity is restored.

H-04A is a 2085' horizontal CST in Zone 2B and a RWO in February, 2009 set a CIBP and shot 25' of perfs. Production remained unchanged after the RWO. H-04A is currently shut-in for high GOR. REASON FOR SIDETRACK H-04A is no longer a competitive producer, and there are no remaining wellwork options. The proposed sidetrack will access reserves in a -30 acre target in northeastern H-pad. The well is in good mechanical condition. H-04A passed an MIT-IA to 2,500 psi on 4/17/11, passed the MIT-T to 1,500 psi on 8/28/08, and failed the MIT-OA. The OA is cemented to surface and had a LLR of .83 gpm on 9/15/03. PPPOT-T passed to 5,000 psi on 2/9/11 and failed the PPPOT-IC on 8/28/11 with a suspected primary seal leak. The tubing was callipered on 3/15/11 and showed an average wall penetrations from 20% to 42% in 66 of 231 joints. The proposed plan for well H-04B is to sidetrack out of the H-04A 3-3/16" liner with a Coiled Tubing Drilling rig on or around August 01, 2011. The existing perforations will be isolated whipstock packer pre CTD operations. The sidetrack will exit the 3-3/16" liner in Zone 4 and drill a 3.0" hole in the target zone Z2A/2B sands. Pre-Rig Work: (scheduled to begin July 10, 2011) 1. W MIT-IA to 2500 psi; MIT-OA to 1200 psi. ' 2. S Pull LTP 3. E Dummy Baker 3-3/16" PackerWS drift ✓, PSA 4. E Set Baker 3-3/16" Packer WS at 11,444' 5. W PPPOT-T to 5,000 psi, function LDS 6. F Load & Kill well. Freeze protect to 2,500' TVD. 7. V PT Tree (MV, SV, WV) P�A 8. V Set BPV - 24 hrs prior to rig arrival Rig Work: (scheduled to begin on August 1, 2011) A 1. MIRU and test BOPE to 250 psi low and 3500 psi high. 2. Mill 2.74" window at 11,444' and 10' of rathole. Swap the well to Quick Drill-n. 3. Drill Build: 3.0" OH, 250' (22 deg/100 planned) with resistivity 4. Drill Lateral: 3.0" OH, 3080' (12 deg/100 planned) with resistivity 5. Run 2-3/8" solid liner leaving TOL at 10,700' 6. Pump primary cement leaving TOC at 11,170', 14.7 bbls of 15.8 ppg Class "G" liner cmt planned N 7. Cleanout liner and MCNL/GR/CCL log 8. Test liner lap to 2000 psi. 9. Perforate liner per asset instructions (-800'). 10. Run LTP if failed liner lap test 11. Freeze protect well, RDMO • Post-Rig Work: 1. Re-install wellhouse and FL's. 2. Kick off well with N2 3. Run Generic GLV's as needed Mud Program: • Well kill: 8.6 ppg brine. • Milling/drilling: 8.6 ppg Quik Dril-n mud for milling window and drilling. Disposal: • All drilling and completion fluids and all other Class II wastes will go to Grind & Inject at DS-04. • All Class I wastes will go to Pad 3 for disposal. Hole size: 3.0" 11,444' MD-14,825' MD Casing Program: • 2-3/8" 4.7#, L-80, STL 10,700' MD— 14,833' MD • • A minimum of 14.7 bbls 15.8 ppg Class"G"cement will be used for liner cementing. • TOC planned at 11,170 MD. Well Control: • BOP diagram is attached. • Pipe rams, blind rams and the CT pack off will be pressure tested to 250 psi and to 3500 psi. • The annular preventer will be tested to 250 psi and 3500 psi. Directional • See attached directional plan. Maximum planned hole angle is 90°, inclination at KOP is 38°. • Magnetic and inclination surveys will be taken every 30 ft. No gyro will be run. • Distance to nearest property—21,460 ft. • Distance to nearest well within pool—1,050'to H-14B 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 • H-17 has a ctr-ctr distance of 538.12'and is currently P&A. • H-17A has a ctr-ctr distance of 432.34'and is a shut-in producer. • H-36A has a ctr-ctr distance of 136.74'and is a shut-in producer. Hazards • One mapped fault crossing at 12,000' MD. • The maximum recorded H2S level on H pad was 160 ppm on well E-102 on 5/7/2011. • The most recent H2S reading for H-04A was 14 ppm on 7/25/10 • Lost circulation risk is considered moderate for this well due to the planned fault crossing. Reservoir Pressure • The reservoir pressure on H-04B is expected to be 3,340 psi at 8,800'TVDSS. (7.3 ppq equivalent). • Maximum expected surface pressure with gas (0.10 psi/ft) to surface is 2460 psi.
