Abstract: Devices for controlling the flow of fluids past a location in a wellbore and methods for using such devices are disclosed. Embodiment devices are configured such that the throughbore is maximized because of the devices' thin cross sectional length. The devices disclosed may use balls, darts or other plugs to seal against a plug seat and prevent flow therethrough, external seals prevent flow therearound and gripping elements, such as slips, prevent movement of the device within the well. Relatively high pressure rating may be accomplished with such thin cross sections by keeping the length of mandrel wall exposed to such pressures short. Some embodiment devices may have a plug seat that is integral, at least in part, with a setting ring and/or have a setting ring that is of one piece with the mandrel.

Abstract: Liner hanger running tool assemblies that may function as a treating string after the liner is set are disclosed. Such assemblies may have a stomp tool that with variable positions so that the stomp tool may be positioned optimally for run-in and them may be moved to a second position that is more optimal during treatment operations. The stomp tool may also serve as a locating device during high pressure treatment to permit full insertion of the seal assembly without impacting the liner hanger assembly with the bottom of the running tool.

Abstract: Hangers and related tools which actuate without fluid or mechanical communication between the interior of the tool and its exterior are disclosed. Devices as disclosed herein may include a piston for applying actuating force based on the fluid pressure outside of the tool. The piston may be fixed to a tubing wall or other body of the tool with a shear element to prevent the tool from actuating until a certain pressure is applied to piston, such as by the static pressure of wellbore fluid at a certain depth, by pressure applied to the annulus from surface, or a combination thereof. Actuation of the tool may cause latches to expand outwardly to engage a latch receptacle fixed in or along the host tubing or such actuation may lead to other hanging members, such as slips, to engage the host tubing wall in order to suspend the hanging string therein.

Abstract: Devices and methods related to setting and testing a packer in a single trip are disclosed. Embodiments disclosed herein provide a tubing engagement element for applying longitudinal force to expand the packer element, such as by compressing an elastomeric element longitudinally to cause radial expansion. Further, upon application of longitudinal force, a second packer element, inside of the first, also sets, isolating the interior of the packer form the exterior. The isolation on the interior of the packer, or tubing attached thereto, permits formation of a pressure differential across the installed packer, facilitating a pressure test to ensure that the packers is adequately set.

Abstract: Devices for controlling the flow of fluids past a location in a wellbore and methods for using such devices are disclosed. Embodiment devices are configured such that the throughbore is maximized because of the devices' thin cross sectional length. Embodiment devices may be optimized to expand into larger casing sizes by use of a multi-part cone system while maintaining the thin cross section. Embodiment devices may also permit the plug to be communicated into the well with the flow control devices, reducing the fluid volume required to treat well stages separated by the disclosed embodiment devices.

Abstract: Devices, systems and methods are disclosed for re-directing fluid flow from the interior of tubing placed in a well to the exterior of the tubing by use of selectively actuatable valves operable by engagement of a plug on a plug seat. The devices, systems, and methods disclosed may provide a flowback bypass for the flow of fluids around obstructions in the tubing when those obstructions occur at a predicted location within the tubing. The systems, devices and methods may also include a locking system operable by, among other things, plug and plug seat valves, and such locking system may be used to prevent opening of the flowback bypass until after a predetermined event has occurred.

Abstract: An apparatus, system and method relating to a valve assembly for use in a subterranean well for oil, gas, or other hydrocarbons. The valve assembly comprises an engaging element with a resilient portion having a first shape when a first pressure differential is applied across the engaging element in a direction and a second shape when a second pressure differential is applied across the element in the direction; a receiving element having sealing section; wherein the engaging element is engagable with the first receiving element to substantially prevent the flow of fluids through the sealing section a pressure differential is applied to the engaging element that is less than a first pressure differential; wherein the engaging element is extrudable through the first receiving element by applying a second pressure differential that is greater than the first pressure differential.
