A lock holds a movable member in position to a stationary member. The set position of the tool is held while being configured to release with the capability of being reset in the same trip to lock a set position of the tool in the same or a new location.

A method for securing a signal propagating line to a downhole component includes configuring the downhole component in a final form prior to securing the line thereto; positioning the line at an outside dimension of the component; and fusing the line to the component with a heat based fusion method and apparatus therefore.

A cut-and-pull spear is configured to obtain multiple grips in a tubular to be cut in tension. A lock feature holds the set position of the slips and seal. The lock can be defeated with an axial force that retracts a spring-loaded dog, and the lock can be reset to the run-in position, with the slips and seal retracted, so that the assembly can… Show more

A cut-and-pull spear is configured to obtain multiple grips in a tubular to be cut in tension. A lock feature holds the set position of the slips and seal. The lock can be defeated with an axial force that retracts a spring-loaded dog, and the lock can be reset to the run-in position, with the slips and seal retracted, so that the assembly can be repositioned in the same trip for another cut. A cam surface prevents setting the slips and seal until the spear is relocated to the next desired cut location or removed from the wellbore. The lock can be defeated with picking up or with a pressuring up on a dropped ball for an emergency release. A surface signal of the release is provided by a stack of disc springs that have to be compressed to release the lock. Show less

A cut and pull spear is configured to obtain multiple grips
in a tubular to be cut under tension. The slips are set mechanically
with the aid of drag blocks to hold a portion of the
assembly while a mandrel is manipulated. An annular seal is
set in conjunction with the slips to provide well control during
the cut. An internal bypass around the seal can be in the open
position to allow circulation during the cut. The bypass can be
closed to control a well kick with mechanical manipulation as
the seal remains set. If the tubular will not release after an
initial cut, the spear can be triggered to release and be reset at
another location. The mandrel is open to circulation while the
slips and seal are set and the cut is being made. Cuttings are
filtered before entering the bypass to keep the cuttings out of
the blowout preventers. Show less

A unitary gravel pack multi-pathway tube includes a body; a gravel slurry flow passage defined within the body; and a control line protection projection extending from and supported by the body, the projection extending laterally from the body relative to an extent of the flow passage and method.

A device or system for controlling fluid flow in a well includes a flow restriction member that transitions from a first effective density to a second effective density in response to a change in composition of the flowing fluid. The flow restriction member may increase in effective density as the water cut of the flowing fluid increases and/or disintegrate when exposed to a selected fluid in the flowing fluid. The flow restriction member may be formed of a water-absorbing material and/or a… Show more

In one aspect of the invention a valve that operates in association with a downhole screen is threaded into the wall of a base pipe after being inserted through a saddle. When the valve body is threaded in, the engagement into the wall threads in the base pipe acts as a sealing force on a ring seal between the saddle and the base pipe and between the valve body and the saddle. The valve itself can be outfitted with a cover with openings that can be integral or removable and disposed at the end… Show more

When the valve body is threaded in, the engagement into the wall threads in the base pipe acts as a sealing force on a ring seal between the saddle and the base pipe and between the valve body and the saddle. The valve itself can be outfitted with a cover with openings that can be integral or removable and disposed at the end of the valve that is innermost to the base pipe. Preferably a series of elongated slots are used that can catch slurry if the well is to be killed while allowing subsequent production to drive the accumulated solids from well killing back into the base pipe.; Another feature places the valve in a base pipe opening under a cylindrical screen section to reduce assembly time and cost of constructing an adjacent housing to one side of the cylindrical screen section to accommodate the valve.

In one embodiment, a flow control device for controlling fluid flow into the production tubular uses a flow restriction member that is actuated by a character change of the formation fluid, such as liquid to gas or oil to water. The flow restriction member can be sensitive to a change in density of the formation fluid. The flow restriction member is passive, self-regulating and does not need any power source or control signal to control fluid flow. In one embodiment, the flow control device automatically rotates into a predetermined orientation upon being positioned in the wellbore. A seal disposed on the flow control devices expands into sealing engagement with an enclosure after the flow control device assumed the desired predetermined position. Show less
