Horizontal drill rig thermal imaging

An integrated circulation temperature model for horizontal well drilling was developed, field-tested, and compared with results from vertical wells in order to accurately predict bottomhole temperature while. [pdf]

Rotary drilling rig digging water wells

The standard method involves percussion drilling in which a drill is alternatively raised and dropped in the descending borehole. It is suited to the drilling of wells in any material from soft clay to the hardest rock. [pdf]
