Abstract: A method of cementing a liner in a well includes mounting a valve assembly that is biased in a closed position to a running tool assembly. The running tool assembly has a stinger inserted through the valve assembly, retaining the valve assembly in an open position. The stinger has a cement retainer releasably mounted to it. After lowering the running tool assembly into engagement with the liner string, the operator pumps a cement slurry through the stinger and the valve assembly. The operator then pumps the cement retainer down the liner string into latching engagement with a lower portion of the liner string. Afterward, the operator lifts the stinger from the valve assembly, causing the valve assembly to move to the closed position. The valve assembly blocks upward flow of fluid from the well conduit through the valve assembly in the event of leakage of the cement retainer.

Abstract: A well is drilled and casing installed utilizing a casing drilling technique. A bottom hole assembly having a drill bit and a fluid diverter is secured to a string of drill pipe and installed within a casing string. Drilling fluid is pumped down the drill pipe string to cause the drill bit to rotate and drill the well while the fluid diverter is in a drilling mode position. At the total depth for the casing string, the operator moves the fluid diverter to a cementing position and pumps cement down the drill pipe and up the casing string annulus. After cementing, the operator moves the fluid diverter to a packer set position and again pumps drilling fluid down the drill string to set the packer.

Abstract: 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.

Abstract: An underreamer for earth boring operations has a tubular body with a passage extending through it. Arms are pivotally mounted to the body and movable between retracted and extended positions. An actuator mandrel, located within the passage in the body, pushes the arms outward when drilling fluid is pumped downward in the drill string. Ports are located in the sidewall of the body and in the actuator mandrel. The ports align with each other when the mandrel moves to its downstream position. The ports divert a portion of the drilling fluid out to jet it across the cutting elements on the arms. The remaining portion of the drilling fluid passes downward to the drill bit and out nozzles of the drill bit.

Abstract: A casing-while-drilling bottom hole assembly is releasably connected with a casing string. A retrieval tool is run into the casing string and latched to the bottom hole assembly. Slips are mounted to the retrieval tool, the slips being retracted during running in. Differential pressure moves the retrieval tool and bottom hole assembly upward, and the slips engage the casing string to prevent downward movement if the pressure differential drops too low. A flow passage extends through the retrieval tool and the bottom hole assembly. A check valve in the retrieval tool allows downward flow through the flow passage but prevents upward flow, so that fluid may be circulated through the retrieval tool and bottom hole assembly while suspended with the slips.

Abstract: A method of installing a drilling tool at a lower end of a string of casing suspended in a borehole employs a setting tool run by wireline. The setting tool is latched to a drilling tool connected a drill lock assembly. After landing in a profile sub at the lower end of the casing, fluid pressure is applied to the interior of the string of casing to actuate the setting tool. The setting tool moves to latch the drill lock assembly to the sub so that torque may be transmitted between the profile sub and the drill lock assembly. The setting tool movement also releases the setting tool from the drill lock assembly for retrieval.

Abstract: A bottom hole assembly in a casing-while-drilling operation is retrieved attaching a wireline to the bottom hole assembly. The density of the fluid in the casing string is lightened to a lesser density than the fluid in the annulus, thereby creating a pressure differential between fluid above the bottom hole assembly and fluid below the bottom hole assembly to exert an upward force on the bottom hole assembly. The operator pulls upward on the wireline to assist the upward force in moving the bottom hole assembly up the casing string.

Abstract: A casing slip joint has been invented that has a first tubular casing member disposed around and releasably connected to a second casing member, the second casing member within and surrounded by the first casing member. Self-destructive shear screws according to the present invention releasably hold the first casing member to the second casing member. In one aspect, a shear screw according to this invention has an outer shear screw with a central recess and an inner member therein. In one aspect the outer shear screw is made of one metal and the inner screw is made of another so that contact by a well fluid sets up a galvanic cell that produces stress corrosion cracking in the outer shear screw that weakens it and/or destroys it. The propagation of such cracks is facilitated by placing one or more notches or recesses in the body of the components.

Abstract: A bottom hole assembly in a casing-while-drilling operation is retrieved by reducing the density of the fluid in the casing string above the bottom hole assembly, creating an upward force on the bottom hole assembly. As the bottom hole assembly moves upward in the casing string, fluid is pumped into the upper end of the annulus and displaced fluid flows out of the upper end of the casing string. The flow rate of the fluid flowing into the upper end of the annulus and the flow rate of the displaced fluid flowing out of the casing string are monitored and compared.
