    Abstract

    We propose an innovative approach that uses well data to constrain the 4D seismic response and help reduce noise levels. Implementation of this well-centric approach requires multiple seismic surveys shot at frequent intervals over the same reservoir. There are now many fields for which such datasets have become available. One such example has been shown previously by Huang and MacBeth (2009) for the non-compacting Schiehallion field. Here we show a further application to the Life of Field Seismic (LoFS) data acquired over the compacting chalk of the Valhall field. The resultant signals identify only those areas of the seismic which are strongly consistent with the well activity, and hence define portions of the reservoir connected to the wells. This information unites the seismic and well domains without the use of the simulation model. The signal tends to be robust and have a much lower noise when compared to the individual 4D seismic difference signatures. This seismic attribute can be used as a diagnostic tool for examining reservoir connectivity and constraining the simulation model.© 2010, Society of Petroleum Engineers.
