| Drilling Activity for Tuesday, August 11, 2009 |
| Well: APS Cholla Pilot CO2 Well |
Rig: WDC Rig 161 |
| Activity: Run and cement 9-5/8"casing |
| WDC personnel cleaned the rig tanks and rigged down the drilling rig. The cement level in the 9-5/8" annulus gradually fell to approximately 100 feet below ground level. The 9-5/8" casing was left in tension for 13 hours after cementing to allow the cement in the wellbore to harden. The 14" and 9-5/8" casings were cut just above ground level. The rig mast was lowered and the rig unit was pulled away from the wellbore. Approximately 80% of WDC’s rig equipment has been demobilized from the drill site. Operations were suspended for the day at 6:30 p.m. |

| Drilling Activity for Wednesday, August 12, 2009 |
| Well: APS Cholla Pilot CO2 Well |
Rig: WDC Rig 161 |
| Activity: Demobilization of rig; Install cellar and wellhead |
| WDC personnel cleaned out solids from its rig tank and loaded out the remainder of the equipment on location. The annular space between the 14" and 9-5/8" casing was grouted to surface. A 6-foot diameter x 5-foot deep cellar was installed around the wellhead and a 13-3/8" x 9-5/8" 3000 psi slip-on wellhead was installed and pressure-tested to 2700 psig for one hour. Operations were suspended for the day at 7:30 p.m. |
