Microbial diversity of hyper thermophilic sulphate reducing bacteria in oil reservoirs of OIL and their control

Souring of oil wells due to SRB (sulphate reducing bacteria) is a common problem faced by the oil industries and it leads to huge economical losses. Large amount of formation water is generated along with the production of crude oil at the Oil India Ltd. This formation water is reinjected into abandoned oil wells after primary treatment. However, due to the high biomass of SRB in formation water, reinjection is difficult and reinjection leads to souring of the oil wells. The objective of the project is to identify all the species of SRB in formation water and its characterization. Characterization will help to design an effective biocide treatment to reduce the population of SRB.
