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.

摘要： 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： 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.

摘要： A disposable setting tool includes a housing having a first end, a second end, and an intermediate portion having an outer surface and an inner surface defining a passage. A piston assembly is arranged in the passage. The piston assembly including a first piston portion and a second piston portion that extends axially outwardly of the second end of the housing. The first piston portion includes a first end portion, a second end portion, and an intermediate section having an outer surface portion and an inner surface portion that extends between the first end portion and the second end portion. The inner surface portion defines a pressure passage. An atmospheric chamber is defined between the inner surface of the housing and the outer surface portion of the piston assembly.

摘要： An anchor and seal system including a slip, a cone in radially expanding communication with the slip, an element in loadable communication with the cone, and a pusher configured to radially displace the element to reside on an element retention surface of the pusher. A method for treating a borehole including running an anchor and seal system above to depth, activating a setting arrangement to anchor and seal the anchor and seal system.

摘要： A downhole tool includes a setting tool having an outer surface, an inner surface defining a passage and a terminal end. An actuator mechanism is arranged in the passage. A setting member is arranged at the terminal end in the passage. The setting member includes a side portion that is angled radially inwardly from a first end portion to a second end portion. A collet member extends over the setting member, and a seal member is operatively connected to the collet member at the second end portion of the setting member.
