Advanced turbodrills for geothermal wells

Conference ·
OSTI ID:6742793
; ;
The development of a new high-temperature, 350/sup 0/C advanced turbodrill for use in drilling geothermal wells is underway. Existing downhole drilling motors are temperature limited because of elastomeric degradation at elevated temperature. The new turbodrill contains high-torque turbine blades and improved seals which allow higher bit pressure drops. This new geothermal turbodrill which is designed for improved directional drilling offers economic alternatives for completing geothermal wells. The advanced turbodrill will be tested in the Los Alamos Scientific Laboratory's hot dry rock geothermal wells.
