Souring and corrosion are multimillion dollar problems in the petroleum industry. A major cause of souring is the oxidation of organic compounds in oil by sulfate-reducing microorganisms. These use sulfate as an oxidant, generating sulfide, which has deleterious consequences including: health and safety risks, reduced quality/value of gas and oil, increased corrosion risk, increased infrastructure costs (corrosion resistant materials, sulfate removal systems), and impact on transport and refining.

You will determine fundamental factors controlling the development of reservoir souring and identify conditions that will either predicate or mitigate the likelihood of souring. A 'souring index' will be devised to predict the souring potential for different crude oils / fields based on understanding of the relationship between fluid properties (oil and formation water characteristics and their interaction with injected seawater) and microbial communities in the reservoir and/or introduced with injection water. Different combinations of these factors will be investigated to identify conditions which lead to the highest and lowest rates of sulfide generation.

You will spend time at BP facilities in the US and UK to access materials, technical and operational expertise.
