Abstract
A method for providing one or more seals in an annular space between a well tubular and the surrounding formation or between pipes of a wellbore system includes determining an in-situ temperature, pressure, earth formation properties and one or more fluids present at one or more locations where the seals are desired. A sealing substance is placed at the locations and allowed to flow into the annular space and undergo curing to form one or more seals. The sealing substance may be a setting expoxy based, phenolic based or polyester based fluid that includes at least one solid component. The sealing substance has physical and fluid dynamic properties compatible with the determined in-situ parameters.
