Abstract: A device or system for controlling fluid flow in a well includes a flow control element and a water detector. The water detector may actuate the flow control element in response to a measurement of a property of the flowing fluid. The water detector may be a capacitive proximity sensor. The measured property may be a dielectric constant. The flow control element may permit a predetermined amount of fluid flow after being actuated to a closed position. Also, the water detector may measure a property of the fluid flowing after the flow control element is in the closed position. A method for controlling a flow of fluid into a wellbore tubular may include positioning a flow control element along the wellbore tubular; measuring a property of a flowing fluid using a water detector; and actuating the flow control element in response to the measurement.

Abstract: 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 porous material. The pores may be water permeable but not oil permeable. A method for producing fluid from a subterranean formation includes controlling a flow of fluid into a wellbore tubular with a flow restriction member. The method may include reducing a flow of water into the wellbore tubular when a percentage of water in the flowing fluid reaches a predetermined value.

The medium may be configured to release the element upon disintegration of the medium. The disintegrating medium may be configured to disintegrate when exposed to a selected fluid. The element may be configured to at least partially restrict flow across a flow path associated with the in-flow control device when released. The flow path may convey the fluid from the formation to a flow bore of the wellbore tubular and the element may be positioned along the flow path. The element may be: a liquid, a solid, a particle and/or particles. The selected fluid may be water, a hydrocarbon, an engineered fluid, and/or a naturally occurring fluid.

Abstract: An inflow control device may include flow control elements along a flow path. The flow control elements may change the inertial direction of the fluid flowing in the flow path. The change in inertial direction occurs at junctures along the flow path. The flow control elements may also be configured to form segmented pressure drops across the flow path. The segmented pressure drops may include a first pressure drop segment and a second pressure drop segment that is different from the first pressure drop segment. The pressure drop segments may be generated by a passage, an orifice or a slot. In embodiments, the plurality of flow control elements may separate the fluid into at least two flow paths. The flow control elements may also be configured to cause an increase in a pressure drop in the flow path as a concentration of water increases in the fluid.

Abstract: A system for use in gravel packing operations wherein a gravel placement mandrel defines an axial flowbore and two or more lateral slurry flow ports for communication of slurry from the flowbore to the interior of the wear sleeve/blast liner. The slurry flow ports are oriented so as to distribute the slurry in different outwardly radial directions. The slurry flow ports are also axially displaced from one another along the gravel placement mandrel body. Relatively equivalent flow rates or flow amounts are provided through each of the slurry flow ports. Improvements are also provided in the geometry of the slurry flow ports to enhance the flow of slurry through them.

Abstract: Two subs are held in a fixed position relative to each other when assembled to a string and run into a wellbore. A reservoir of fluid is defined in a wall between the subs. The reservoir has one or more outlets connected by a short jumper line to an adjacent tool to be operated. At the appropriate time, set down weight breaks a shear pin to reduce the reservoir volume and create pressure in the exit lines. The exit lines can be connected to operating pistons in adjacent tools to actuate them or to perform other desired functions using a stream of pressurized fluid. The device can be set for one time or multiple cycles where fluid in the reservoir can be replenished and re-pressurized for multiple cycles of operation.

Abstract: Disclosed herein is a fiber optic cable downhole tool mounting system. The system includes, a downhole tool, a support member attached to the downhole tool and a fiber optic cable parameter transmissively mounted to the downhole tool by the support member. The support member has an elongated body with a pair of legs extending therefrom, the pair of legs intersect at an oblique angle and define a volume therebetween receptive of the fiber optic cable. The fiber optic cable is attached to the support member and the support member is attached to the downhole tool such that a parameter encountered by the downhole tool is sensible by the fiber optic cable.

Abstract: 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 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.

Abstract: Devices and methods for monitoring wellbore conditions while conducting hydrocarbon production within a wellbore, particularly an open-hole wellbore, having multiple zones within. A production tubing string assembly is made up having a plurality of packers for sealing within an open-hole wellbore having multiple individual zones. The production tubing string includes production nipples and one or more fiber optic sensor lines disposed upon the outside of the production tubing string. The sensor line or lines are disposed through the packers using a pass-through system so as to provide unbroken sensing line(s) to the surface of the wellbore. This allows temperature, pressure or other wellbore conditions to be monitored at the surface in each of the individual zones of interest.

Abstract: A series of screens with restrictors to equalize flow through base pipe perforations downstream or upstream of each restrictor features a valve member in the openings so that the screens are closed to flow for run in. Pressure can be developed within the base pipe for operation of downhole equipment below the screens such as a mud motor or in the screen liner such as a packer with no need for an internal string or wash pipe. The openings can be opened selectively when the associated equipment connected to the base pipes has been operated. The valve member can be actuated to open in a variety of ways such as applied pressure, temperature or a change in well fluid condition.
