This study investigates the application of GreenZyme, a biodegradable enzyme-based surfactant, to improve gas recovery by modifying fluid dynamics within coal seams.

Enzymatic oil recovery methods align with the growing demand for sustainable oil production. The enzymes used are biodegradable and non-toxic, reducing environmental risks. Unlike chemical surfactants or solvents, enzymes do not accumulate in the environment or cause long-term damage.

Bio-enzyme solution shows that this agent can increase the recovery rate of crude oil by 5.0%, reduce the water injection pressure by 40%.
