METHODS OF ENHANCING FRACTURING STIMULATION IN SUBTERRANEAN FORMATIONS USING IN SITU FOAM GENERATION AND PRESSURE PULSING

摘要

Methods of enhancing fracturing stimulation in subterranean formations using in situ foam generation and pressure pulsing including providing a jetting fluid comprising an aqueous base fluid; providing a fracturing fluid comprising an aqueous base fluid, a gelling agent, a proppant agent, a gas generating chemical, and a gas activator; introducing the jetting fluid into a subterranean formation to create or enhance at least one fracture therein; introducing the fracturing fluid into the at least one fracture; applying intermittent pressure pulsing to the fracturing fluid to extend the at least one fracture.
