PSEUDOELASTIC MATERIALS AS ADDITIVES TO ENHANCE HYDRAULIC FRACTURING

摘要

Systems and methods for enhancing hydraulic fracturing productivity for recovery of a reservoir fluid from a reservoir formation 12 having an open fracture 16 includes providing a shape memory filter 18 that is pseudoelastically deformed and contained within a soluble container 24. The shape memory filter 18 and soluble container 24 are pumped into the open fracture 16 so that the soluble container 24 dissolves and the shape memory filter 18 returns to an expanded filter shape. A proppant 22 is pumped into the open fracture 16 so that the proppant is trapped by the shape memory filter 18 and forms a column across the open fracture 16.
