Comparing Chemical Enhanced Oil Recovery Eor Ior with Thermal and Gas Methods

The Chemical Enhanced Oil Recovery (EOR/IOR) employs three main categories of chemicals: polymers, surfactants, and alkali agents. Polymers increase the viscosity of injected water, reducing fingering and improving sweep efficiency. Surfactants lower interfacial tension between oil and water, mobilizing trapped oil droplets. Alkalis react with acidic components in crude oil to...
