Microbiologically influenced souring (MIS) has been defined as the presence of sulfide in produced gas or fluids due to current microbiological activities. Several important problems related to souring include the removal of H2S before transport or end-use, H2S corrosion, safety, environmental concerns, and the costs associated with these problems. Over the past several years, the Gas Research Institute (GRI) has sponsored research on souring in production and storage facilities. Research at storage facilities has led to the development of initial profiles, detection kits (MISKITS), and field guides, as well as chemical and microbiological databases. Souring investigations at production facilities have addressed the extent of souring in the United States and potential cost savings. Also, localized souring in the Antrim formation in the Michigan basin has been investigated, the results of which suggest souring due to current MIS.
