摘要

Apparatus and methods for perforating a subterranean well are provided. In general perforating apparatus, including a pre-weakend casing apparatus and a propellant assembly, is deployed within a formation of the well. Activation of the propellant assembly perforates the pre-weakened casing apparatus and the well formation. The invention can accomplish perforation and sand-control operations in a single trip.
