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 non-ballistic force generating mechanism includes a non-ballistic first actuator operable to output a first force profile defining a first pressure for a first stroke length, and a non-ballistic second actuator operable to output a second force profile following the first force profile, the second force profile defining an second pressure that is substantially greater than the first pressure for a second stroke length that is less than the first stroke length.

摘要： A system for degrading a structure includes the structure formed of a degradable-on-demand material, an ignitor arranged to transfer heat to the structure; and, a mechanical impactor movable with respect to the structure, wherein the ignitor increases in temperature upon impact of the mechanical impactor into the ignitor, and heat from the ignitor initiates degradation of the structure.
