Conference to Feature Demo of Drill Rig That Rotates Casing and Follows Bit Through Caving

摘要

Overburden The most unwelcome water well and geothermal borehole drilling conditions are the caving in of the well or borehole before the casing is installed. Redrilling the same caving zone again and again takes time and fuel that eat up profits. Because geothermal borehole drilling is production drilling, overcoming caving conditions quickly is essential for a profitable geothermal loop field drilling job.
