Course Description

As reservoirs age and water injection is implemented for pressure maintenance, there is an inherent risk of reservoir souring due to the co-mingling of injection waters and formation waters. Souring occurs as a result of the down hole activity by a specialized group of micro-organisms, the sulphate -reducing bacteria (SRB). The prediction of reservoir souring requires assessment of three key factors: (1) Microbial generation of H₂S (2) Transport and scavenging of microbial generated H₂S in the reservoir and (3) Partitioning of H₂S between the oil, gas and water phases. This course covers all topics related to reservoir souring and water breakthrough.

Course Goal

To enhance participants’ knowledge, skills, and abilities necessary to help predict and avoid reservoir souring and its negative consequences.
