Abstract

It is a common practice nowadays to interpret 4D seismic in view of the production and injection history. Evaluation of the well influence on 4D seismic is often done manually by simultaneously looking at 4D attributes and production/injection profiles. A well2seis technique was developed to automatically correlate 4D signal to the well activity (e.g. Yin et al., 2015). As opposed to individual 4D vintages, the well2seis correlation attribute provides a framework for estimating the drainage radius of wells and understanding the spatial connectivity of the reservoir for maturing reservoir models. We integrate the well2seis technique in a consistent workflow that assists 4D interpretation for the purpose of model maturation, well planning and generally reservoir management. A workflow is applied to a compartmentalized North Sea reservoir where the inter-field communication pattern needs to be determined. As in-fill drilling of an undrained segment is planned in the near future, the sealing properties of major faults need to be understood in order to optimize the field drainage strategy. The study demonstrates that the workflow can assist in maximizing the value of 4D seismic and production/injection data in the decision making process.
