Title: Controlling the pressure within an annular volume of a wellbore

Patent ·
OSTI ID:1176395
; ; ;

A process is described for replacing at least a portion of the liquid within the annular volume of a casing system within a wellbore with a second liquid. The second liquid is preselected to provide a measure of control of the pressure within the annular volume as the fluid within the volume is being heated.
