ABSTRACT:
In a process for injecting a steam-foam-forming mixture into a subterranean reservoir to displace oil, injecting a mixture containing only as much noncondensible gas as required for substantially reducing the mobility of an injected steam-foam-forming mixture containing a given kind and amount of surfactant and electrolyte, which amount of noncondensible gas to add is calculated from a specified equation interrelating the reservoir temperature and pore size.
