reservoir souring prediction: a novel screening method

reservoir souring prediction: a novel screening method

prediction of the onset of reservoir souring, i.e. production of excess hydrogen sulphide, has been a major concern in oil industry during the last decades. assuming that the principal source of h₂s generation inside the reservoir is the microbial activity, we are able to predict the potential of reservoir souring based on bacterial activity effective parameters. to do so, a collection of physical and nutritional criteria for the bacterial activity was provided. step-wise comparison of these parameters between the nominated reservoir and basic criteria enables us to evaluate the reservoir souring probability without any complicated simulation work. in the last section, this proposed method is verified using data from previous cases.
