Better Reservoir Management through Improved Water-Injection Methods with Data Analysis and Detailed Fracture/Reservoir Modeling

The search for practical engineering tools to better manage water injectors has been ongoing for many years. Simple analytical solutions have proven inadequate, and most reservoir simulators do not explicitly model water injectors. This paper proposes a methodology of using detailed and coupled fracture and reservoir modeling to ensure proper injection start-up procedures, and managing injection rates to avoid out-of-zone injection. This is combined with simple rate-pressure data to understand injection behavior, and from that control the process.
