摘要： A seat for a tubular treating system includes a single piece body having a central portion, and a frustoconical surface extending longitudinally from the central portion in a first direction configured to radially expand slips urged thereagainst. The seat also includes a collar extending longitudinally from the central portion in a second direction configured to be radially expanded into sealing engagement with a structure in response to a frustoconical member urged thereagainst. A seal surface is sealably engagable with a plug run thereagainst, and the seal surface is longitudinally displaced from the collar in the first direction.

摘要： 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 tubular anchoring system includes a frustoconical member having a first frustoconical portion and a second frustoconical portion. The first frustoconical portion is tapered in a direction opposing a direction of taper of the second frustoconical portion and slips in operable communication with the first frustoconical portion are radially expandable in response to longitudinal movement of the first frustoconical portion relative to the slips. A seal in operable communication with the second frustoconical portion is radially expandable in response to longitudinal movement of the second frustoconical portion relative to the seal, and a seat having a surface configured to be sealingly engagable with a plug runnable thereagainst.

摘要： An object including a housing, a cone movably received in the housing, a piston body attached to the cone, a valve disposed as a part of the object and separating hydrostatic pressure from pressure at an interface between the housing and the piston body, and a trigger configured to open the valve at a selected circumstance. A method for moving a selected downhole tool including running an object into a borehole, counting features in the borehole using a sensor in the object, opening the valve at a selected count, flooding the interface with hydrostatic pressure, driving the piston body away from the housing, and moving a radially expandable 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 frac plug system, downhole tool and method of securing a frac plug system in a wellbore in a formation. A mandrel includes a first end and a second end. A setting assembly is coupled to the mandrel at the first end, and an anchor is arranged at the second end of the mandrel and receptive to the setting assembly. The anchor is settable to engage the wellbore. A bottom sub is arranged at the second end of the mandrel and includes a first member movable relative to the mandrel. A gas generates a pressure to shift the first member along the mandrel to move the anchor against the setting assembly, securing the setting assembly in the wellbore via radial deployment of the anchor. The mandrel is separated from the bottom sub to leave the setting assembly and the anchor in the wellbore.

摘要： A method for operating in a borehole penetrating a formation is disclosed. The method includes disposing in the borehole an assembly comprising a load-bearing and oil-disintegrable tool comprising a polymeric composite; performing a downhole operation; and disintegrating the load-bearing and oil-disintegrable tool with a hydrocarbon fluid. The polymeric composite comprises an oil-disintegrable polymer which is one or more of the following: a polydicyclopentadiene, polypropylene, polyurethane, polycarbonate, polysulfone, or a high density polyethylene, the polyurethane being a polyhedral oligomeric silsesquioxane-modified polyurethane, a lauryl methacrylate graft polyurethane copolymer, a divinylbenzene crosslinked polyurethane, or a combination comprising at least one of the foregoing.
