Abstract: A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

Abstract: A modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules.

Abstract: The multi-acting valve design features an outer collet around a mandrel with the collet spring biased to a first position where one set of flow ports on one side of a seat with a captive ball can be closed so that the valve acts to prevent fluid loss. When the collet engages a profile and the mandrel is set down the ports above and below the seated ball allow a bypass path around the central path of the mandrel where the ball is seated on a seat. The ports above and below the seated ball communicate into an annular space provided by a sleeve around the mandrel that is supported by the collet assembly that finds temporary support on a profile in a surrounding tubular. The mandrel has an exterior detent to selectively hold the bypass open when the collet assembly is landed on another support to advance it above the mandrel detent.

Abstract: An apparatus for controlling fluid flow into a wellbore tubular includes a flow control member that selectively aligns a port with an opening in communication with a flow bore of the well bore tubular. The flow control member may have an open position wherein the port is aligned with the opening and a closed position wherein the port is misaligned with the opening. The flow control member moves between the open position and closed position in response to a change in drag force applied by a flowing fluid. A biasing element urges the flow control member to the open or the closed position. The apparatus may include a housing receiving the flow control member. The flow control member and the housing may define a flow space that generates a Couette flow that causes the drag force. The flow space may include a hydrophilic and/or water swellable material.

Abstract: An apparatus for performing a wellbore operation, such as a gravel packing, includes a tool body, a flow passage formed in the tool body, the flow passage connecting a first space with a second space; and a flow control device positioned along the flow space. The flow control device may include a valve element configured to allow uni-directional; and a flow control element configured to allow flow in bi-directional flow. The valve element and the flow control element may be arranged to form a split flow path between the first space and the second space.

Abstract: Fracturing tools for fracturing multiple zones of a wellbore are disclosed. In certain embodiments, the fracturing tools comprise two or more crossover subs coupled together and having a crossover sub window alignment assembly operatively associated with either an isolation sleeve disposed within the bores of the crossover sub-assemblies or with the crossover sub assemblies themselves. Actuation of the crossover sub window alignment assembly opens and closes the windows of each of the crossover sub-assemblies so that different crossover sub-assemblies can be activated to fracture various wellbore locations.

Abstract: Wear is reduced in abrasive slurry service at an outlet into an annular space defined by the wellbore and around the tool. In a gravel packing application with a crossover, the slurry exits a central passage and goes into an internal annulus in the tool. Turning vanes that make at least one full turn and that have a height at least partially the height of the annular space are there to impart a swirl movement to at least a portion of the slurry stream. The swirling motion has beneficial effects of reducing turbulence which allows a velocity reduction for a comparable output volume. As a result of the lower turbulence leading to the final exit from the tool into the surrounding annulus, the exit ports experience reduced erosion and longer service life.

Abstract: A crossover tool that resists the erosive forces of high velocity slurry streams of gravel in downhole fracturing and gravel packing operations employs hardened inserts that protect the inside face of the housing as well as the openings through the crossover housing wall. The inserts have an extending portion that goes through housing openings preferably to the outer surface of the housing. The inserts also have inboard flanged surfaces that preferably abut or overlap to give preferably full inner wall protection to the housing from the flow of abrasive slurry. The inserts can be secured to each other or to the interior of the housing to hold them firmly in place.

Abstract: An apparatus for controlling fluid flow between a wellbore tubular and a wellbore annulus includes a passage between a bore of the wellbore tubular and the wellbore annulus. The passage causes cavitations in a flowing fluid made up of mostly water. The cavitations activate a flow control device that controls fluid flow into the wellbore tubular. In one method, the flow control device includes a pressure chamber pressurized by high-pressure fluid associated with the cavitations. The pressure in the pressure chamber actuates a piston assembly coupled to a closure element that restricts fluid flow into the wellbore tubular. Alternatively, a power generator generates an electrical signal in response to the cavitations and transmits the electrical signal to the flow control device. In response to the electrical signal, the flow control element activates one or more devices that move a closure element to restrict fluid flow into the wellbore tubular.

Abstract: A deflection device keeps high velocity gravel slurry flow from directly impinging the wellbore wall in open hole and breaking loose the filter cake coating on the wall or, in a cased hole, prevents the direct impingement of gravel slurry on the casing which can cause wear from erosion. The slurry exist from an intermediate annulus in a crossover that is fitted with movable members that can be pivotally mounted for rotational displacement by the pumped slurry to act as a deflector to prevent or minimize direct impingement on the wellbore wall or casing. When the flow stops the deflectors can pivot back to their original positions. The deflectors can be simply replaced when worn.
