Intentional degradation of hollow particles for annular pressure build-up mitigation
Abstract:
A method of servicing a wellbore may comprise providing a treatment fluid comprising a carrier fluid and hollow particles, wherein the hollow particles may comprise an outer wall that encapsulates a gas. The method may further comprise introducing the treatment fluid into a wellbore annulus and trapping at least a portion of the treatment fluid in the wellbore annulus. The carrier fluid may degrade the outer wall of the hollow particles in the wellbore annulus and release the encapsulated gas.
