Gravitational Displacement Apparatus for treating Sustained Casing Annulus Pressure and Surface Casing Vent Flow

摘要

An apparatus and method for treating sustained casing annulus pressure (SCP) and surface casing vent flow (SCVF) by continually and consistently injecting higher density fluid into the annulus of a well, wherein the higher density fluid will slowly migrate downwards and displace lower density fluids and gasses due to the pull of gravity, thus helping to control or eliminate SCP by creating the hydrostatic column in the annulus.
