The process also includes performing an imbibition test on a plurality of stage one surfactants, each stage one surfactant mixed with a first treatment fluid and using a portion of the core sample to obtain a wettability index or measurement of capillary pressure. The process includes selecting a stage one surfactant and performing an oil recovery test on a plurality of stage two surfactants, each stage two surfactant mixed with a second treatment fluid. The process includes selecting a stage two surfactant and injecting the selected stage one surfactant into a matrix of the low permeability reservoir. In addition, the method includes injecting the selected stage two surfactant into a fracture network of the low permeability reservoir."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-functional surfactant solution for improving hydrocarbon recovery","description":"A fluid injection process includes removing a core sample from a low permeability reservoir.
