摘要:
A treatment plug includes, an anchor runnable and settable within a structure having, at least one slip movably engaged with the anchor to move radially into engagement with the structure in response to longitudinal movement of the at least one slip relative to surfaces of the treatment plug, at least one seal having a deformable metal member configured to radially deform into sealing engagement with the structure in response to being deformed radially outwardly, and a seat that is sealingly receptive to a plug.

A treatment plug includes an anchor runnable and settable within a structure having, at least one slip movably engaged with the anchor to move radially into engagement with the structure in response to longitudinal movement of the at least one slip relative to surfaces of the treatment plug, the at least one slip being perimetrically wedged between fingers of the treatment plug that are not radially movable, at least one seal having a deformable metal member configured to radially deform into sealing engagement with the structure in response to being deformed radially outwardly, and a seat that is sealingly receptive to a plug.

A treatment plug includes, an anchor runnable and settable within a structure having, at least two slips movably engaged with one another to cause the at least two slips to move radially into engagement with the structure in response to longitudinal movement between the at least two slips. The treatment plug also has at least one seal having a deformable metal member configured to radially deform into sealing engagement with the structure in response to longitudinal compression of the deformable metal member, and a seat that is sealingly receptive to a plug.

摘要:
A casing/liner string buoyancy arrangement including a casing/liner string, and a material defining a volume disposed within the string, the material excluding downhole fluids from the volume, the volume being of a lower specific gravity than the same downhole fluids. A method for managing buoyancy of a casing/liner string including configuring a casing/liner string, running the string, and selectively maintaining or degrading the material to adjust buoyancy of the string. A borehole system including a borehole in a subsurface formation, and an arrangement disposed in the borehole.

An object includes a housing, a cone received in the housing, a piston body attached to the cone, a gas evolution compound disposed in the object, an interface between the housing and the piston body, an interface feed fluidly connecting the gas evolution compound with the interface, and a trigger to evolve gas from the compound at a selected circumstance. A method for moving a tool including running an object into a borehole, counting features in the borehole using a sensor in the object, evolving gas from the gas evolution compound at a selected count, pressurizing the interface with the evolved gas, driving the piston body, and moving a shoulder member toward a larger diameter end of the cone. A borehole system including a borehole in a subsurface formation, a string disposed in the borehole, and an object disposed within or as a part of the string.
摘要:
A plug with a closure member including a body defining a flow bore and a closure member seat, a closure assembly connected to the body, the assembly including a closure member, and a hold open feature to hold the closure member in an open position, the hold open being configured to release the closure member upon a selected hydrodynamic force upon the closure member.
摘要:
An apparatus for setting a plug in a borehole penetrating a subsurface formation includes a tool mandrel defining a chamber having a port and a power charge disposed in the chamber for emitting a pressurized gas upon ignition. The apparatus also includes an outer sleeve at least partially surrounding the tool mandrel and defining an annulus between the outer sleeve and the tool mandrel where the annulus is in communication with the port. The apparatus further includes a piston disposed in the annulus and having an outer surface facing uphole within the annulus, the piston being in mechanical communication with a setting sleeve of the plug, wherein displacement of the setting sleeve causes setting of a slip and a seal of the plug.
