摘要： An underreamer for forming a cavity within a well bore includes a fluid motor having a first body and a second body arranged about a longitudinal axis. The first body is adapted to rotate about the longitudinal axis in relation to the second body when fluid is passed between the first and second bodies. The fluid motor further defines a longitudinal tubing passage adapted to allow passage of the fluid motor over a tubing string. At least one cutting arm is coupled to rotate with the first body, and radially extendable into engagement with an interior of the well bore to form the cavity.

摘要： An underreamer for forming a cavity from within a well bore includes a housing adapted to be disposed within the well bore. The underreamer includes an actuator partially slidably positioned in the housing. The actuator comprises a first portion and a second portion. A cross-sectional area of the second portion is larger than a cross-sectional area of the first portion. The underreamer includes at least one cutter set, wherein each cutter set has a first end and a second end. The first end of each cutter set is pivotally coupled to the housing. The second end of each cutter set is pivotally coupled to a connector. An axial force applied to the actuator is operable to slide the actuator relative to the housing causing the second portion of the actuator to contact each cutter set and extend each cutter set radially outward relative to the housing from a retracted position to a first position. The actuator may also include a stop member proximate an end of the actuator. The stop member may be operable to force the connector to slide relative to the housing during the application of the axial force, causing each cutter set to further extend radially outward relative to the housing from the first position to a second position.

摘要： A method for removing water and producing methane from a subterranean coal seam. The method includes drilling a first substantially vertical well bore to the depth of the target coal seam, enlarging the bore of the vertical well at the depth of a target coal seam to provide an enlarged cavity, drilling an offset well intersecting the cavity substantially horizontally and then drilling through the cavity in order to drill substantially horizontal drainage well bores in the coal seam. The method may be used as a pre-mining step in conjunction with subterranean mining of the coal seam in order to remove methane and other dangerous gases and excess water from the coal seam in advance of mining operations.

摘要： A flow control system includes a pump positioned in a well to remove liquid from the well. A check valve is positioned in the well and includes an open position and a closed position. The check valve in the open position allows gas from a producing formation of the well to flow past the check valve, while the check valve in the closed position substantially reduces gas flow at the pump from the producing formation. A compressed gas source is in fluid communication with the well to provide compressed gas to move the check valve to the closed position.

摘要： A flow control system includes a pump positioned in a well to remove liquid from the well. An isolation device having a valve body and a valve spool is positioned downhole of the pump. The valve spool is rotatably received by the valve body and is capable of rotating between an open position and a closed position. During removal of the liquid from the well, the valve spool is in the closed position to substantially reduce fluid flow past the valve spool and thus gas interference at the pump.
