摘要： A magnetic retrieval tool used for collecting metallic debris and material from within a wellbore or other surrounding downhole tubular. The tool includes a tool mandrel with a removable insert which contains one or more magnets. The insert is formed such that both the north and south magnetic poles of the one or more magnets are able to attract metallic debris.

摘要： A wellbore cleaning device having a unitary tool mandrel surrounded by a retaining sleeve that is rotatable with respect to the mandrel. A locking ring is used to secure the retaining sleeve to the mandrel. Cleaning blades are retained within recesses in the retaining sleeve and are biased radially outwardly from the recesses by springs.

摘要： Downhole valves comprise a housing having a bore, a port, upper and lower recesses disposed in an inner wall surface of the bore, the upper recess disposed above the port and the lower recess disposed below the port, and upper and lower pistons disposed in the bore. The upper and lower pistons each comprise a bore with a port in communication with housing bore. During run-in, the housing port is blocked by the lower piston. Actuation of the lower piston unblocks the housing port and aligns the lower piston port with the lower recess. Actuation of the upper piston closes the housing port and aligns the upper piston port with the upper recess. Alignment of the ports of the pistons with their respective recesses permits fluid flow through the tool both when the valve is opened by the lower piston and closed by the upper piston.

摘要： A debris catcher uses induced circulation from a venturi to urge debris laden flow into the lower end of a housing. An inlet tube maintains velocity so as to keep the debris moving with the fluid stream as it goes up the inlet tube. A screen fits over the open end of the inlet tube and runs down around the inlet tube toward the entrance of the debris laden fluid into the lower end of the housing. There is a clearance around the cylindrical portion of the screen so some flow can exit that way. There is also an open exit through the top of the screen that can be reached after the fluid stream makes two hairpin turns. Many modules can be stacked. Each module has a large screen area for flow to exit and progressive modules can have smaller screen openings in an uphole flow direction.

摘要： A debris catching device for downhole milling features modular debris receptacles that are held in the housing in a manner that facilitates stacking and a generally undulating flow path to facilitate dropping of the debris into the receptacles as the remaining fluid travels up the tool for ultimate screening before the fluid exits the tool to flow up to the surface or in a reverse circulation pattern back to the mill below the debris catcher. The modules can also be aligned with flapper valves at the top of each module to prevent debris in the tool from falling to the mill if circulation is turned off. The mill is configured to have an off-center return path preferably as large as the passage through the mill body to aid circulation and cutting performance.

摘要： A method of abandoning a borehole includes, running a tool into the borehole, cutting a casing with a first portion of the tool, reaming the borehole in an area where the casing has been cut with a second portion of the tool, disconnecting a drillstring from the tool, and cementing the borehole through the drillstring.
