ABSTRACT:
A wellbore cleanup tool and method are described. In one embodiment, the fluid is displaced with a cup seal into the tubing/drill pipe as the seal is lowered into the wellbore. In another embodiment reverse circulation directs debris into the tubing/drill pipe as it is loosened on the trip into the hole. The returning fluid laden with debris can be directed to either below the cleaning equipment or above it when used with a cup seal and a return port adjacent to it.
