    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： A system including a first component, a second component disposed radially adjacent to the first component, and a centralizer disposed between the first component and the second component for at least partially filling a radial clearance between the first component and the second component. The centralizer is formed at least partially from a disintegrable material responsive to a selected fluid. A method of completing a borehole is also included.

    摘要： A frustoconical member includes a metal composite that has a cellular nanomatrix comprising a metallic nanomatrix material; a metal matrix disposed in the cellular nanomatrix; and a first frustoconical portion. A process of making the frustoconical member includes combining a metal matrix powder, a disintegration agent, and metal nanomatrix material to form a composition; compacting the composition to form a compacted composition; sintering the compacted composition; and pressing the sintered composition to form the frustoconical member having a tapered portion on an outer surface of the frustoconical member. The frustoconical member can be used by contacting a frustoconical portion of the frustoconical member to a tapered surface of an article; applying pressure to the frustoconical member; urging the frustoconical member in a direction relative to the article to expand a radial dimension of the article; and contacting the frustoconical member with a fluid to disintegrate the frustoconical member.
