What is MEOR ?

MEOR or Microbial Enhanced Oil Recovery is an enhanced oil recovery method, where a carefully selected microbes are nurtured in the reservoir. The microbes "eat" the heavy components of the crude oil and convert them into higher components so that they can move easily from the reservoir to the well and then up to the surface. The microbes also release chemicals such as surfactants, CO2 etc that also assist in oil recovery.

Nutrients and oxygen must be supplied to the reservoir for the microbes to flourish and give the desired results. Hence, it is often difficult to implement the process across the reservoir.

Globally, this method seems to have limited success.
