Oilfield reservoir souring: forecasting and simulating microbiological sour gas production

Oilfield reservoir souring: forecasting and simulating microbiological sour gas production

All oilfield reservoirs have different souring propensities, meaning that Oil Operators must view all injector/producer (I/P) pairs as unique with respect to H2S gas production, and sour gas control and mitigation strategies. 

Rawwater’s DynamicTVS© software model describes the cooling of an oilfield reservoir due to water-flooding and the subsequent growth of sulfate-reducing microorganisms, resulting in sulfide production at the topsides facilities. Outputs from the DynamicTVS model are used to inform and direct key operational decisions worldwide. This type of sour gas forecasting work has resulted in huge cost savings for Operators through optimised, cost-effective material selection and chemical dosing in the field.  Case studies from North Sea and West African assets will be presented:

  • Where early oilfield reservoir souring forecasting, in conjunction with pressurised bioreactor simulation studies, were used to inform field planning and development at an early decision gate, and;
  • Where the DynamicTVS model and pressurised simulation studies saved an Oil Operator in excess of $100m.



Matt Streets has been an industrial microbiologist since 2010 and has worked as a Senior Research Scientist at Rawwater for the past 8 years, further developing the in-house, souring forecasting model, DynamicTVS© and the elevated pressurised bioreactor simulation systems.

In addition to running single-client souring forecasting and pressurised bioreactor studies, Matt also manages Rawwater’s joint industry souring project which will soon be entering its sixteenth year. 

His areas of research aim to improve the industrial understanding of different injection chemistries, chemical treatments and downhole reservoir conditions to better identify each oilfield’s unique souring potential.

Matt is currently undertaking a part-time PhD in Environmental Geochemistry and Geomicrobiology at the University of Manchester.
