摘要:
Porous objects, such as porous balls, may be employed within telescoping devices to control proppant flowback through a completed well during production. The telescoping devices may connect a reservoir face to a production liner without perforating. Acid-soluble plugs initially disposed within the telescoping devices may provide enough resistance to enable the telescoping devices to extend out from the production liner under hydraulic pressure. The plugs may then be dissolved in an acidic solution, which may also be used as the hydraulic extension fluid. After the plugs are substantially removed from the telescoping devices, the reservoir may be hydraulically fractured using standard fracturing processes. The porous balls may then be inserted into the telescoping devices to block proppant used in the fracturing process from flowing out of the reservoir with the production fluids.

摘要:
A system for fracturing a subterranean formation includes a housing having one or more radially directed ports therein. A valve disposed within the housing proximate the one or more ports. A seat member interactive with the valve to rapidly prevent or substantially retard fluid flow therethrough. A method for initiating a fracture in a subterranean formation is included.

A valving device includes a tubular with a port and a sleeve slidably sealingly engaged with the tubular between a first position and a second position. The sleeve is configured to occlude the port when in the first position and uncover the port when in the second position. The valving device is configured such that pressure inside the tubular does not urge the sleeve toward the second position while pressure applied radially outwardly of the tubular and the sleeve urge the sleeve toward the second position.
摘要:
A slip element, including a substrate at least partially formed from a material degradable upon exposure to a fluid; and an outer surface disposed on the substrate. A method of removing a slip element including exposing a substrate of the slip element to a downhole fluid for degrading the substrate.

A system for fracturing a formation includes a tubular positionable within a formation borehole having at least one port therethrough configured to provide fluidic communication from inside the tubular to the formation borehole. The system also includes a seal sealably attachable to both the tubular and walls of the formation borehole, a seat in operable communication with the tubular and a member in operable communication with the seat such that movement of the seat relative to the tubular causes the member to engage the walls and provide stress thereto.
摘要:
A treatment plug includes, a metal tubular expandable into sealing and anchoring engagement with a surrounding structure, the metal tubular having a shoulder at an inner radial surface thereof, and a composite plug sealable with the metal tubular and anchorable to the shoulder
摘要:
A zero backlash downhole setting tool including a mandrel; a body lock ring at the mandrel; a setting sleeve in operable communication with a device to be set; a rotary take-up in tensile force transmissive contact with the device to be set; and a follower housing configured to follow the rotary take-up in a first mode of operation and extend away therefrom in another mode of operation, the follower being engaged with the body lock ring and method.
摘要:
A valving system includes a tubular and a sleeve slidably engaged with the tubular having a seat thereon. The sleeve is configured to occlude flow from an inside of the tubular to an outside of the tubular when in a first position, allow flow between an inside of the tubular and an outside of the tubular at a first location upstream of the seat and a second location downstream of the seat when in a second position, and allow flow between an inside of the tubular and an outside at the tubular at the first location and not the second location when in a third position. The valving system also includes a disappearing member in operable communication with the tubular and the sleeve configured to prevent movement of the sleeve to the third position until disappearance thereof.
摘要:
An expandable screen assembly includes, a tubular, and a plurality of screens in operable communication with the tubular each of the plurality of screens is configured to radially expand in response to a same force longitudinally compressing the plurality of screens.
