Foam-forming surfactant compositions

摘要: This invention relates to foam-forming surfactant compositions having at least two surfactants whereof one is a sulfosuccinamate, and sulfosuccinate, optionally including, solvent. Methods of recovering oil or gas by generating foam, feeding the foam into subterranean oil- gas-bearing geological formation, collecting mineral natural driven in production well, wherein generated intimate mixing more described herein with generator, introduction water gases, together intermittently alternating sequence, slugs which may be supercritical non-supercritical state, water, composition(s) can admixed if state introduced separately as solution are also provided.
