| 20080223576 | Controlling pressure and static charge build up within an annular volume of a wellbore - 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 comprising at least one polymerizable monomer and at least one antistatic agent to control build up of static charge. The second fluid is preselected to provide a measure of control of the pressure within the annular volume as the fluid within the volume is being heated. | 09-18-2008 |
