Title: Multi-stage geologic fracturing

Abstract

Explosive geologic fracturing methods, devices, and systems can be used in combination with other geologic fracturing means, such as hydraulic fracturing methods, devices and systems, or other fluid-based fracturing means. An exemplary method comprises introducing an explosive system into a wellbore in a geologic formation, detonating the explosive system in the wellbore to fracture at least a first portion of the geologic formation adjacent to the wellbore, and introducing pressurized fluid into the wellbore to enhance the fracturing of the first portion of the geologic formation. Such multi-stage fracturing can further enhance the resulting fracturing of geologic formation relative to explosive fracturing alone.
