Disclosed is reclosable sleeve assembly including a housing defining one or more flow ports that provide fluid communication between a wellbore annulus and an interior of the housing, an outer sleeve arranged within the housing and movable between a closed position, where the outer sleeve occludes the one or more flow ports, and an open position, where the one or more flow ports are exposed, and an inner sleeve concentrically arranged within the outer sleeve and defining a plurality of flow slots, the inner sleeve being movable between an open position and a closed position where, when in the open position, the plurality of flow slots are axially aligned with the one or more flow ports.

A downhole circulating valve includes a generally tubular outer housing having a generally axially extending internal passageway. At least one generally longitudinally extending circulating passageway is formed through at least a portion of the housing. At least one exterior port and at least one interior port are in fluid communication with the circulating passageway. At least one seal plug is disposed within the circulating passageway. The seal plug has a first position relative to the housing wherein the seal plug is remote from the exterior port and the interior port, thereby allowing fluid flow between the exterior port and the interior port through the circulating passageway. The seal plug has a second position relative to the housing wherein the seal plug is between the exterior port and the interior port and wherein the seal plug forms at least one metal-to-metal seal with the circulating passageway, thereby preventing fluid flow between the exterior port and the interior port.

A downhole injection apparatus having a sleeve disposed in a tubular housing. The sleeve and housing define an annular orifice through which steam flows prior to injection into the wellbore. Water condensate collects at the orifice or restriction proximate the orifice and is mixed with or entrained into the flow of steam. The sleeve preferably has a plurality of generally radial ports such that steam flows from interior the sleeve to the annulus. Preferably the injection ports and sleeve ports are angled to reduce or eliminate radical changes in direction of the steam flow.

A downhole impact generator () is adapted to be moved to a target location within a wellbore () for transmitting a jarring force to a well tool () positioned in the wellbore (). The downhole impact generator () includes a downhole power unit () having a moveable shaft () and a jarring tool (). The jarring tool () is operably engageable with the well tool () and is operably coupled with the moveable shaft () of the downhole power unit () such that when the jarring tool () is operably engaged with the well tool (), linear movement of the moveable shaft () energizes the jarring tool () such that a jarring force can be transmitted by the jarring tool () to the well tool ().

A subterranean well completion has a tubular structure in which a remote controlled robot is permanently disposed. The robot is self-propelled, programmable, receives instructions from and communicates data to the surface, and is adapted to receive power from a downhole source and perform a variety of well tasks such as, for example, positioning valves and other well tools and sensing the values of predetermined downhole parameters and relaying the sensed information to the surface. The robot, which is operable without physical intervention through the tubular structure to the robot, propels itself to a location in the tubular structure at which a desired well task is to be performed, performs the task and then parks itself in the tubular structure until another well task is to be performed by the robot.

An expandable wirefinder () for locating a wire downhole comprises a sleeve () and a dual collet assembly (). The dual collet assembly () has first and second collet members () each having plurality of collet fingers (). The dual collet assembly () is slidable relative to the sleeve () to operate between running and finding positions. In the running position, the first collet member () is partially disposed within the sleeve () with its collet fingers () inwardly radially biased by the sleeve () and the second collet member () is disposed within the first collet member () with its collet fingers inwardly () radially biased by the sleeve (). In the finding position, the collet fingers () of the first collet member () radially expand to form gaps therebetween and the collet fingers () of the second collet member () radially expand into the gaps.

An apparatus for gravel packing a production interval ( ) of a wellbore ( ) comprises first and second sand control screen assemblies ( ) connected downhole of a packer assembly ( ) and a cross-over assembly ( ) that provides a communication path ( ) downhole of the packer assembly ( ) for a gravel packing fluid and a communication path ( ) uphole of the packer assembly ( ) for return fluids. A wash pipe assembly ( ) extends into the first and second sand control screen assemblies ( ) forming an annulus ( ) therebetween. A valve ( ) is positioned within the wash pipe assembly ( ) in a location between the first and second sand control screen assemblies ( ). The valve ( ) is actuatable from a closed position to an open position when the beta wave ( ) is proximate the location of the valve ( ).
