The prediction of reservoir souring requires assessment of three key factors:
Generic computer-based predictive models currently exist which, although based on the same fundamental principles, take different approaches to assessing the level of H 2S generation. Each model has its own strengths and weaknesses.
Petroleum and reservoir engineers who will be actively working on studies, and be involved in assessing the results of studies.
