Abstract
A method for increasing the efficiency by which fracture fluids are produced back from a hydrocarbonaceous fluid bearing formation. To remove said fracture fluid, a chemical blowing agent is placed into the formation. After placement of said blowing agent and fracturing the formation, the blowing agent decomposes thereby either causing the filter cake to become more porous or providing a driving force for fluid load removal from the matrix. Increased porosity enhances communication between the formation and the fracture, thus increasing the efficiency of fracture fluid production. Gas liberation within the matrix establishes communication pathways for subsequent removal of hydrocarbonaceous fluids by displacing fluid loads into the fracture and the well.
