Abstract
Systems and methods for determining pressure within a sealed annulus based on the conservation of mass to test the structural integrity of the sealed annulus. The conservation of mass is applied to fluid(s) in a sealed annulus by using the total mass of the fluid(s) in the sealed annulus, instead of volume changes, as the basis for estimating pressure changes due to temperature changes.
