Concentric gravel pack with crossover tool and method of gravel packing |
摘要 |
A packer with a liner assembly depending from it is packed off and anchored in well casing so that a screen portion of the liner assembly straddles casing perforations within a producing formation. An outer tubing string is lowered through the well casing and engaged with the packer to isolate the formation from well fluids above the packer and to provide a passage to the surface for the formation fluids.
