Abstract
A chemical blowing agent is incorporated into a polymer formulation to provide delayed foaming in a subterranean reservoir when, via catalysis through reservoir temperature or minerals present, the reservoir itself initiates or accelerates decomposition of the chemical. The resultant gelled foam expands and stiffens thereby closing pores in a more permeable zone of said reservoir. Once foaming is completed, a carbon-dioxide or water-flooding oil recovery process can be used to recover hydrocarbonaceous fluids from a zone of lesser permeability.
