    Abstract: A compressible object is described that may be utilized in drilling mud and with a drilling system to manage the density of the drilling mud. The compressible object includes a shell that encloses an interior region. Also, the compressible object has an internal pressure (i) greater than about 200 pounds per square inch at atmospheric pressure and (ii) selected for a predetermined external pressure, wherein external pressures that exceed the internal pressure reduce the volume of the compressible object and wherein the shell being designed to reduce localized strains of the compressible object during expansion and compression of the compressible object.

  • Patent number: 4931068
    Abstract: A method for consolidating finely divided diamond particles to produce a substantially fully dense article having improved resistance to wear and cracking. Diamond particles are heated to an elevated temperature for compacting to form the fully dense article. The article is then held at an elevated temperature and time sufficient to rearrange and substantially reduce the dislocations in the article resulting during compacting to achieve a substantially strain-free state in the article. The article is then cooled to room temperature after which it may be given an improved leaching treatment to achieve superior thermal stability.
