摘要： A running tool for well drilling operations is carried by a running string into and out of a wellbore. A collet is carried by the running tool, the collet having fingers with a radially expanded position arranged to latch against a wellbore shoulder in the wellbore. The fingers are resiliently and radially contractible. A shear element is carried by the collet, the shear element preventing the fingers from radially contracting to unlatch the running tool while the shear element is intact. If a selected axial force is applied against the shear element, it shears, freeing the collet fingers to retract. The collet may be part of a tool to set and release a liner hanger from engagement with a string of casing.

摘要： A method for drilling with a liner includes: providing a liner string including an upper portion extending towards surface and a lower portion; drilling to a depth with the liner string; disconnecting the upper portion from the lower portion; pulling the upper portion from the well; and leaving the lower portion in the well to line the wellbore. A drilling assembly for drilling a borehole with a borehole liner includes: an upper liner string; a lower liner string including an upper end and a lower end; a releasable connector connecting the lower liner string to the upper liner string; and a drilling assembly connectable at the lower end of the lower liner string.

摘要： A method for reverse circulating a tool upwardly through a wellbore, the method including: providing a manipulator tool including an upper end and a lower end, conveying the manipulator tool down hole to a position adjacent a downhole tool, using the manipulator tool to manipulate the downhole tool, and reversing fluid flow through the well to create a pressure differential about at least one of the manipulator tool and the downhole tool such that the at least one of the manipulator tool and the downhole tool is lifted upwardly through the wellbore. A manipulator tool for use in a reverse circulating method is also described as are a tool catcher, a tool catching assembly and a tool catching method.

摘要： A straddle packer tool comprises a mandrel and a housing. Spaced packers are carried by the housing. A plurality of bypass ports are arranged in the mandrel and housing for aligning in several positions: a first downhole position for bypassing fluid around the packers and through the mandrel; an intermediate position wherein the bypass ports are misaligned and a first internal pressure actuates the packers to isolate a zone and a second higher internal pressure releases a stop for enabling relative movement to an uphole position wherein the bypasses are misaligned and the mandrel's bore is opened to isolated zone.
