Abstract
A project on the application of MEOR in one of the Wintershall candidate fields has been initiated. The project aims mainly at developing nutrient formulations for stimulating microbial activity in terms of oil recovery and defining reservoir and process parameters for the selected field leading to a field trial. The project is structured with a workflow consisted of 5 work packages. The sampling activities were extended with a sub-surface sampling in one of the candidate fields to investigate the effect of pressure on bacterial activity. The works on the determination of growth rates and metabolite activities of microbial consortia derived from one field is continuing with batch tests and micromodels. Dynamic screening experiments are going on in sandpacks and cores under sterile and anaerobic conditions. Numerical works are performed in two parallel ways. On one hand, an analytical model is being applied to evaluate relevant process parameters. On the other hand, a numerical simulator is being tested and validated to implement it into a reservoir simulator. The recent results both in experimental and numerical parts are presented and discussed in the paper.
