ABSTRACT:
Method and apparatus for processing drilling mud wherein mud containing lost circulating material is passed from the well to a separator device where it is separated from the drilling mud and is reintroduced into the drilling mud after the mud has been cleaned of undesirable solid particulate. In the separator, the lost circulating material is retained on a coarse screen while the mud and drilling solids pass to a finer mesh screen. The finer mesh screen removes the drilling solids and allows the mud to pass to the mud tank. The separator includes structure to recirculate the lost circulating material to the mud tank.
