Evaluation of high temperature lubricants for downhole motors in geothermal applications

Conference ·
OSTI ID:5962530
A Bearing-Seal Package is being developed for use with downhole motors and turbines for drilling geothermal wells. The lubricant will be sealed in the bearing section which will allow the bearings to operate directly in the lubricant. The development of the Bearing-Seal Package involves the improvement of high temperature seals and lubricants. Candidate high temperature lubricants were tested in the High Temperature Lubricant Tester under elevated temperatures and pressures. A list of candidate high temperature lubricants, a description of the lubricant test program, and the lubricant test results are presented.
