MEOR

Microbial Enhanced Oil Recovery

Microbial Enhanced Oil Recovery (MEOR) is a tertiary EOR technique, commonly used as a means to increase ultimate recovery after primary and seconday production has completed. MEOR focuses on introducing microbes into the reservoir in order to improve the recovery of trapped oil and to increase the recovery factor. 

Field trials show an initial average oil production increase of 200-300% and an initial water cut decrease of 10-40%.

MEOR Process

Develop Customized Microbes

Scale-Up & Ferment Microbes

Injection & Soaking Period

Production

MEOR Mechanism

Alkane Degredation

Emulsification

Gas Production

Degrades long chain alkanes to short chain, effectively reduces oil viscosity

Produces localized gas to help lift oil and adds additional pressure to push oil out from pores

Produces surfactant during metabolism, reducing interfacial tension and oil emulsions in water
