摘要： A method of removing a liquid from a wellbore with a plunger, comprising: flowing a wellbore fluid stream in contact with the plunger and in an uphole direction within the wellbore conduit, wherein the plunger is located within a downhole region of the wellbore conduit and includes an actuatable external seal assembly operable between a retracted position in a low fluid drag state and a deployed position in a high fluid drag state; maintaining the plunger in a low fluid drag state while a variable associated with the wellbore fluid stream is outside a threshold range to permit the plunger to remain within the target region of the wellbore conduit during the flowing; transitioning the external seal assembly to a high fluid drag state responsive to the variable associated with the wellbore fluid stream being within the threshold range and thereby conveying the plunger and liquid in the uphole direction.

摘要： Selective stimulation ports (SSPs), wellbore tubulars that include the SSPs, and methods of operating the same are disclosed herein. The SSPs are configured to be operatively attached to a wellbore tubular and include an SSP body, an isolation device extending within an SSP conduit of the SSP body, a retention device coupling the isolation device to the SSP body, and a sealing device seat. The isolation device is configured to selectively transition from a closed state to an open state responsive to a shockwave, which has greater than a threshold shockwave intensity, within a wellbore fluid that extends within a tubular conduit of the wellbore tubular. The methods include generating the shockwave within the wellbore fluid such that the shockwave has greater than the threshold shockwave intensity. The methods further include transitioning the isolation device from the closed state to the open state responsive to receipt of the shockwave.

摘要： A perforating gun assembly for use in perforating multiple intervals of at least one subterranean formation intersected by a cased wellbore and in treating the multiple intervals using a diversion agent, such as ball sealers. In one embodiment, the apparatus of the present invention comprises a perforating assembly having a plurality of select-fire perforating devices interconnected by connector subs, with each of the perforating devices having multiple perforating charges. The apparatus also includes at least one decentralizer, attached to at least one of the perforating devices, which is adapted to eccentrically position the perforating assembly within the cased wellbore so as to create sufficient ball sealer clearance between the perforating assembly and the inner wall of the cased wellbore to permit passage of at least one ball sealer.

摘要： Corrodible wellbore plugs, systems and methods are disclosed herein. The methods include flowing a corrodible wellbore plug that is at least partially formed from a corrodible metal to a downhole location within a wellbore conduit and retaining the corrodible wellbore plug at the downhole location by operatively engaging an engagement structure with a wellbore tubular that defines the wellbore conduit. The methods include pressurizing a portion of the wellbore conduit uphole from the corrodible wellbore plug and flowing a corrosive reservoir fluid from the subterranean formation into contact with the corrodible metal to release the corrodible wellbore plug from the downhole location. The methods also may include removing the wellbore plug without utilizing a drill-out process. The systems include a corrodible wellbore plug that includes a plug body and a retention mechanism, which includes a slip ring formed from the corrodible metal and that includes the engagement structure.
