Hole M51-2015-1
This was the original hole began in spring 2015. The plan for this hole is to rotary down to a depth approximating where drilling ceased in the fall and continue coring the Pierre Sahle through the lower part of the section folllowed by coring of the Niobrara Fm. and tagging the Carlile Shale.
The Enid M51 rig was used to rotary down to 475 ft and the hole was electric and sonic logged. The sonic log data looks good but the SP-Resistivity may have issues due probably to inadequate grounding.
The Enid was moved off and the Mobile coring rig was moved on during the week of April 13. A problem in one of the rig pumps caused a delay as of April 15 so waiting on parts. See operations for more detailed reports.
