Conclusion

Growth Conditions

Found in environments with no oxygen and the presence of sulfur

For example:

Surface water

Deep ground water

Sea water

Pluming systems

Water heaters

Human gut

Oil and gas production processes

History and life cycle

Control Methods

Biocides

Nitrate Injection

Remove of Sulfur before transport

Outline

SRB in Oil and Gas

History and life cycle

Pipeline corrosion

Ideal growth Conditions

History and life cycle

Significance in oil and gas

Control measures

One of the oldest micro-organisms, over 3 billion years old

Von Wolzogen Kuhr 1937

Anaerobic that breath Sulfur instead of oxygen

Exhale sulfide gas

Responsible for 75% corrosion in production wells

Over 50% in buried pipelines
