Question

Microbes are helpful in oil recovery because:

• A. they act as surfactants.
• B. they increase natural pressure.
• C. they secrete oil.
• D. they decrease natural pressure.

The correct option is B

they increase natural pressure.

Microbes are injected deep into the oil reservoir, where they feed on nutrients and release gas. This process increases the natural pressure levels of the oil reservoir and aids in oil recovery.
