| 12:00 AM | 5:30 PM | Drilled 7 7/8" hole. Rig was 5,600' 6:30 AM, soaping, carrying 1 1/2" stream of water, and drilling 36 minutes per kelly. Bit has 82 hours on it. Gas check at 5,298', showed 20/10ths H20 through 1" (189 mcf/day). Rig was 5,854' at 4:30 PM. Instructed rig to drill one more kelly, clean hole and begin tripping out. Scheduled logging truck for 2 AM. Reached TD of 5,890' at 5:30 PM. |

| 12:00 AM | 12:00 PM | Drilled 7 7/8" hole. Rig was 4,708' at 6:45 AM, soaping, carrying 1 1/2" stream of water, and drilling 30 minutes per kelly. Gas check at 4,339', showed 1/10ths H20 through 1" (15 mcf/day). Bit seems okay (drilling smoothly) but bit trip may still be necessary. Rig was 4,860 at 11:20 AM, soaping, drilling 30 minutes per kelly. Gas check at 4,799 (which should be through the Benson) showed 60/10ths H2O through 1" (82 mcf/day). Rig was 5,105' at 6:00 PM, soaping, drilling 35 minutes per kelly. |

| 12:00 AM | 12:00 AM | Drilled 7 7/8" hole. Rig was 3820' at 7:00 AM, soaping, carrying 1 1/2" stream of water, and drilling 40 minutes per kelly. Gas check at 3,661', no show. Unlikely that gas checks will reveal much, considering the volume of water being carried. Rig was 4,064' at 3:30 PM, soaping, drilling 40 minutes per kelly. Bit has 55 1/2 hours. Expected to trip for bit at 60 hours (8:00 PM), or sooner, if bit craters.Bit seemed okay. Did not trip, continued to drill. |

Temperature was below 10 degrees, and rig was having problems with weight indicator freezing, which slowed drilling down. Gas check at 2,919' showed 1/10" water through 1" (11 mcf/day). Rig was 3,230' at 12:20 PM, soaping, drilling 35 minutes per kelly. Rig was 3,452' at 6:15 PM, soaping, drilling 40 minutes per kelly.
