Abstract
A method of controlling the equivalent circulating density of an epoxy resin, used to cement a wellbore, the method includes introducing an epoxy resin into an annulus defined by a casing string and an inner wall of the wellbore. Backpressure is asserted on the epoxy resin as it flows through the annulus. Some embodiments include adjusting the cross sectional area of the annulus exit using a valve or other mechanism to control the backpressure and thus increase or decrease the equivalent circulating density of the epoxy resin.
