Abstract:
1. A multi-zone fracturing and sand control completion system employable in a borehole, the system comprising: a casing; a fracturing assembly including a fracturing telescoping unit extendable from the casing to the borehole and a frac sleeve movable within the casing to expose the fracturing telescoping unit during a fracturing operation and to block the fracturing telescoping unit after the fracturing operation is completed; and, an opening in the casing, the opening including a porous material and a dissolvable plugging material, the dissolvable plugging material capable of maintaining frac pressure in the casing during the fracturing operation through the telescoping unit, and the porous material including at least two different materials fused together by exothermic heat resulting from solid state reactions between alternating layers of the at least two different materials.
