Abstract This paper presents a three-stage integrated workflow using thermal/ geomechanical and thermal/ chemical simulation models to prevent reservoir souring during high concentration sulphate water injection. Reservoir souring takes place when sulphate reducing bacteria (SRB) is activated...

As a result, the regions that experience significant concentration and saturation gradients are more confined, and that leads to improvements in the computational efficiency of the adaptive scheme. The robustness of the approach is demonstrated using a highly heterogeneous...
