ABSTRACT:
An improved method and apparatus is disclosed for use in a return line system of a drilling rig to determine a volumetric fluid flow rate and, therefore, to aid in detecting a kick in a well. The apparatus comprises an ultrasonic level sensor, an ultrasonic Doppler velocity sensor and a digital computer electrically coupled to the level sensor and the Doppler velocity sensor to determine the fluid flow regime in the return line system. The flow regime is determined by the programmed computer to accurately determine the volumetric fluid flow rate in the return line system in real time, during drilling operations.
