BHA RECONFIGURATION REDUCES COSTS IN AUSTIN CHALK

Redesigning the bottom-hole assembly (BHA) has reduced horizontal drilling costs in the Austin Chalk. More than 30 runs have been made with a new design in which an adjustable stabilizer is placed ahead of a straight, positive-displacement motor (PDM) instead of behind. Cost reductions have occurred through reductions in tool failures, slide lubricants, and the number of wells needed to drain the reservoir. In environments where mud weights have been greater than 14 ppg, savings have exceeded $200,000/well.
