Abstract
A drilling mud clarification or reclamation system is provided. High gravity and low gravity solids are removed from the drilling mud in respective centrifugal separator stages. A plurality of in-line mass flow sensors are provided to provide real-time indication of the effectiveness of the clarification of the drilling mud, and to provide control signals to a central control station. The heavier weight components are separated from the mud and returned to the system for further use. The lighter weight components are removed and are discarded to clean the mud. A cuttings dryer is provided to remove oil from cuttings which have been separated from a shale shaker stage. A de-sludging centrifuge is also provided to remove very fine cuttings which may have a harmful effect on the viscosity of the mud.
