Oil and gas are vital to many industries and are of great importance to maintaining industrial civilization as we know it. The energy industry is a complex one, engaging in the extraction of oil and gas from deep underground and offshore and transportation of it to refineries and chemical plants for further processing. Microbial control technology plays an important role at each stage, facilitating safe and reliable operations, while at the same time helping to make sure that the valuable resources are conserved.

The conditions in which oil and gas are often extracted and its subsequent transportation to refineries are conducive to bacterial growth, thus biocides are utilised to control the growth of various types of bacteria. Without effective treatment, microbial contamination can cause pipeline and equipment corrosion, the souring and plugging of wells and reservoirs and consequently can reduce flow rates. 

The presence of water is the main determinant for microbial growth in fuels. Water dissolved in the fuel can condense on tank walls, moisture in the air can enter through floating tank lids or other vents, poorly designed tanks do not drain efficiently, leaving sediment or sludge harboring microorganisms. As in most cases of microbial bio-deterioration of materials, the best control treatment is prevention. The use of microbial control products in fuel storage tanks helps reduce bacteria, algae and biofilm formation; aids in the control of microbial influenced corrosion and reduces reservoir-souring, protecting the fuel efficiently.
