摘要
A process and related apparatus for enhancing the oil recovery from an oil well are described. An embodiment of the process generally includes selection of a candidate reservoir; collecting oil formation water samples under anaerobic conditions; selecting media and enriching the microbes derived from the formation water; characterizing and identifying the selected consortium; mass scale production of the selected consortium; anaerobically preparing a defined composition nutrient medium, transportation of the nutrient medium by ISO tankers and the consortium by a specially designed field laboratory unit to the selected well treatment site; injecting the medium and consortium into the reservoir of the well; closing the well for the proliferation of microbes for one to three weeks; and allowing the microbes to dislodge oil in the reservoir and thereby enhance recovery of oil from the well.
