Methods for well completion
This application discloses methods for consolidating incompetent earth formations. More particularly, the disclosed methods are directed toward consolidating incompetent earth formations and providing fluid communication of improved quality without the attendant production of loose formation materials. These methods are accomplished by first perforating the particular formation being completed in such a manner as to establish a circuitous flow passage. Suitable fluids are then successively injected into one end of the circuitous flow passage as communication is established at its other end with an enclosed chamber initially at a reduced or atmospheric chamber for flushing out debris in the flow passage as well as loosened formation particles to develop the flow passage into an enlarged cavity in the formation. Once the chamber is filled, the injected fluids permeate the formation adjacent to the enlarged cavity to stabilize or consolidate the formation and maintain the integrity of the cavity. (17 claims)
