| Abstract: |
This paper describes the development of a new drilling fluid outflow meter for use in the diagnosis and characterization of lost circulation experienced during the drilling of geothermal wells. The design and operation of the new meter, known as the rolling float meter, is described, and its laboratory and field performance data are presented. Considerations for using the rolling float meter with pump speed indicators for lost circulation characterization are discussed. Procedures for calibrating the flowmeters and data display and analysis techniques are outlined. |
