Compositions and methods for fracture sealing

Abstract

Described herein are methods for fracture sealing and redevelopment. Methods for fracture sealing and redevelopment can comprise injecting a sealant composition through a first wellbore in fluid communication with an unconventional subterranean formation such that the sealant composition flows into at least one fracture present in a first region of the unconventional subterranean formation. The sealant composition can solidify within the fracture, thereby at least partially closing the fracture. Subsequently, the unconventional subterranean formation can be fractured via the first wellbore and/or via a second wellbore in fluid communication with an unconventional subterranean formation. The solidified sealant composition can direct fracture formation away from the first region of the unconventional subterranean formation and towards virgin rock.
