  • Buoyant particles designed for compressibility
    Patent number: 11332652
    Abstract: A collection of compressible particles. The compressible particles are intended to be used for attenuating pressure within a confined volume such as a trapped annulus. Preferably, the compressible particles buoyantly reside within an aqueous fluid, forming a fluid mixture. Each of the compressible particles is fabricated to collapse in response to fluid pressure within the confined volume, and comprises carbon. The particles may each have a porosity of between 5% and 40%, and a compressibility of between 10% and 30%, at up to 10,000 psi. Each of the particles has a resiliency of between 80% and 120%.
    Type: Grant
