摘要： Fluid plugs as downhole sealing devices and methods include providing a stimulating fluid to a casing conduit that is defined by the production casing to stimulate a portion of a subterranean formation within which the production casing extends. The methods further may include providing a sealing fluid to the casing conduit, providing a sealing device to the casing conduit, and flowing the sealing fluid and the sealing device to a perforated section of the production casing. The methods further may include locating the sealing device on a perforation, generating a fluid plug within the perforated section of the production casing by increasing a viscosity of the sealing fluid, and retaining the sealing device proximate the perforation with the fluid plug.

摘要： Methods for stimulating a subterranean formation comprising providing a stimulating fluid stream to a casing conduit that is defined by a production casing that extends within the subterranean formation to increase a fluid pressure within the casing conduit. The methods further include locating an isolation device on an isolation sleeve to fluidly isolate a downhole portion of the casing conduit from an uphole portion of the casing conduit and opening an injection port that is associated with the isolation sleeve to permit an injection port fluid flow into the subterranean formation. The methods also include sealing the injection port and creating an uphole perforation in the uphole longitudinal section of the production casing responsive to the fluid pressure exceeding the threshold perforating pressure.

摘要： Isolation systems for use in a wellbore include two or more tubular segments and at least one coupling assembly. The at least one coupling system is adapted to couple the first and second tubular segments together. The at least one coupling system is further adapted to block at least a portion of the wellbore annulus. The at least one coupling system is further configured as a leaky isolation assembly to separate the wellbore annulus into at least two isolated zones when disposed in the wellbore. At least one isolation zone has at least two outlets including a first outlet through an opening into the tubular and a second outlet past the leaky isolation assembly. The isolation system is configured to provide the isolation with hydraulics during well operation that preferentially drives fluids through the first outlet and at least substantially prevents fluid from passing the isolation assembly.

摘要： Flow control assemblies comprise a housing that includes a housing body that defines a housing conduit, an injection conduit that extends through the housing body, and a ball sealer seat. The ball sealer seat defines a portion of the injection conduit, is defined on an inner surface of the housing, and is sized to receive a ball sealer to restrict fluid flow from the casing conduit through the injection conduit. The flow control assemblies further include a sliding sleeve that is located within the housing conduit and defines an isolation ball seat. The flow control assemblies also include a retention structure that is configured to retain the sliding sleeve in a first configuration and to selectively permit the sliding sleeve to transition from the first configuration to a second configuration.

摘要： A method of completing a well involving remediating a condition of screen-out that has taken place along a zone of interest. The method includes forming a wellbore, and lining at least a lower portion of the wellbore with a string of production casing and placing a valve along the production casing, wherein the valve creates a removable barrier to fluid flow within the bore. The barrier is removed by moving the valve in the event of a screen-out. This overcomes the barrier to fluid flow, thereby exposing ports along the production casing to the subsurface formation at or below the valve. Additional pumping takes place to pump the slurry through the exposed ports, thereby remediating the condition of screen-out.

摘要： Perforation devices including trajectory-altering structures and methods of utilizing the same. The perforation devices include a magazine, a barrel, a trajectory-altering structure, and an action. The magazine is configured to contain a plurality of cartridges. The barrel extends between a breech, which is configured to receive a selected cartridge of the plurality of cartridges that includes a selected projectile, and a muzzle, which is configured, upon firing of the selected cartridge, to permit the selected projectile to exit the barrel at a muzzle velocity and with a muzzle trajectory. The trajectory-altering structure is configured to act upon the selected projectile such that, upon exiting the trajectory-altering structure, the selected projectile defines a modified trajectory that differs from the muzzle trajectory. The action is configured to transfer the selected cartridge from the magazine to the breech of the barrel and fire the selected cartridge.
