Rig 337 senior drilling staff drilled 3140 feet on the first well manually in 18 hrs (174 fph). On the second well the Autodril Navigator was used and the same section was drilled with the same bit in 13.75 hrs (240 fph) a 27.3% improvement. That whole well was drilled using one less bit with an est. total saving of $60k.

Increase “Rotating Time” from 50%s to 80%s for all succeeding wells Took off roughly 2 ¼ days with faster drilling and skipping previously necessary bit trips Savings per well of up to $70k; monthly operational savings of upwards to $400k in reduced bit trips, MWD and motor failures previously due to vibration The Auto Driller has been a standard on all JB Hunt rigs since 2007.

Drilling Superintendent Performance analysis done after 6 months shows 10-26% improvement of drilling time and operational efficiency

118, County Reagen, Wolfberry Play, multi well operation infill and extension drilling - Consultant Wylie Norton wyliean@hotmail.com The Navigator was responsible for a 29.5 reduction in Bit hours, 27% reduction in rig days and saved two $25K bits on the three wells.  This equates to a saving of approximately  $190,400 on three wells. In addition the bits on those wells were pulled and were still green and could be re-run giving additional savings.
