Turbodrilling in the geothermal environment

Geothermal drilling, historically, has presented what seemed to be insurmountable barriers to the efficient and extended use of downhole drilling motors, especially those containing elastomeric bearing or motor components. In addition to being damaging to rubber, the typical temperatures of 350-700/degree/ F create other operating problems as well. Recent innovations, specifically in the Turbodrill design, have opened unrealized potentials and allowed, for the first time, extended downhole drilling of geothermal wells. A presentation is made of the case histories of recent Turbodrill performances in all areas where used. Furthermore, data is presented showing the performance of insert, diamond, and Stratapax bits as they relate to the Turbodrill, together with forecasts as to the potential that turbodrills have to offer in accelerating and controlling the drilling of geothermal and hot petroleum wells. 1 ref.
