Estimation of caving volumetric-flow using the ultrasonic Doppler Method

CT&F Ciencia, Tecnología & Futuro
Estimating the volumetric flow of cuttings and cavings that are extracted and transported by the drilling mud into the flow line while drilling a well is of major interest to for drillers so that they can understand the drilling conditions and maintain ...
