Abstract
Abstract An apparatus and method are provided for running, setting and anchoring a liner in a well bore casing, said apparatus being connectable to a tubular member extendible to the top of the well. The apparatus comprises an inner longitudinally extending body with an outer longitudinally extending body being around the inner body. Connection means on one of said inner and outer bodies are provided for connection of a liner extending below the apparatus. Expander means are carried on one of the inner and outer bodies, with gripping means being carried on the other of the inner and outer bodies. The gripping means are engagable with the expander means such that the gripping means are shifted into gripping engagement with the casing. A manipulatable tubular running tool is releasably secured to the inner and outer bodies. Drag means are mounted on the running tool and are slidable longitudinally along the casing, the drag means resisting longitudinal travel of the apparatus while in the well bore with sufficient frictional force to support the weight of one of the inner and outer bodies therebelow. Disengaging means are provided for selective disengagement of the running tool from the inner and outer bodies. Setting means are carried on the running tool and are operably associated with the drag means, the setting means being responsive to manipulation of the running tool to longitudinally shift one of the inner and outer bodies with respect to the other of the inner and outer bodies to anchor the liner to the casing. Wiper means selectively disengagable from the running tool are provided together with means for disengagement of the wiper means from the running tool. Side seal means are carried on the running tool to detect disengagementof the running tool from the inner and outer bodies.
