Abstract

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

First claim

The invention claimed is:

1. A method comprising:
a) providing a jetting fluid comprising an aqueous base fluid;
b) providing a fracturing fluid comprising an aqueous base fluid, a gelling agent, a proppant agent, a gas generating chemical, and a gas activator;
c) introducing the jetting fluid into a subterranean formation to create or enhance at least one fracture therein;
d) introducing the fracturing fluid into the at least one fracture,
wherein prior to introducing the…
