Methods for well completion

OSTI ID:6437556
This application discloses methods for consolidating incompetent earth formations surrounding a cased well bore and providing for unobstructed fluid communication. More particularly, the disclosed methods are directed toward consolidating a portion of an incompetent earth formation adjacent to a cased well bore to preclude the subsequent displacement of loose particles of formation materials as well as to provide relatively unobstructed fluid communication. These methods are accomplished by first injecting a suitable consolidating agent or agents into the particular formation being completed. Then, once it is believed that the injected portion of the formation has sufficiently firmed, a perforation is made through the casing and cement into the firmed formation portion to provide a clean unobstructed fluid-communication path.
