摘要：
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. The interior region of the shell is at least partially filled with a foam. The internal pressure of the compressible object may be greater than about 200 psi (pounds per square inch) at atmospheric pressure, greater than 500 psi at atmospheric pressure, greater than 1500 psi at atmospheric pressure or more preferably greater than 2000 psi at atmospheric pressure.
