As South Texas operators have successfully transitioned to drilling VCL’s in high-temp applications, one of the main challenges has been motor performance across the entire run. With temp swings anywhere from 150 – 200 degrees F, selecting the right fit that will give you the power to efficiently drill the upper section but also maintain sufficient rubber integrity required to finish strong can be a challenge.
Legacy’s 6/7 12.1 motor fitted with DynaDrill’s new XE DynaMic fit provides a solution that proved to be a step change in one area of Webb County. The very first well for a new client set a field record for all Austin Chalk wells drilled within a 5-mile radius and continued what has been a great string of performances by this Legacy Motor.
