| Drilling Activity for Saturday, August 22, 2009 |
| Well: APS Cholla Pilot CO2 Well |
Rig: Bearcat Rig 2 |
| Activity: Drilling in the Supai Formation |
| The well was circulated to clean the hole and the workstring was retrieved to the casing shoe. Operations were suspended to allow the crews to obtain H2S Safety Training. The crew resumed retrieval of the workstring but operations were suspended to cut drill line (damaged section of line observed). The bit was retrieved from the wellbore and replaced. The drilling assembly was lowered into the wellbore to bottom (no fill on bottom) and drilling resumed. Drilling continued from 2,721 ft to 2,855 ft at an average rate of penetration of 11.6 ft/hr. |
