Nitrate Biotechnology for Oil Industry and Gas Application

摘要

Nitrate treatments have been used for many years to control nuisance H2S smells from sewage works and similar organic-rich treatment plant which has been considered as biotechnology treatment.Recently,nitrate has also been used in field wide applications to oilfield systems for SRB(sulfate reducing bacteria)and sulfide control,including application to injection water,reservoirs and produced water treatment plant the primary objective of the work was to recommend appropriate nitrate treatment strategies that will cost-effectively control problems caused by bacterial growth in the water injection system.The implementation of the technology resulted in significant reduction in chemical and operating costs.Moreover,the treatment proved effective controlling sulfide even in the challenging operational conditions of flowing significantly less than the specified flow rate of 1 m/s.
