EAGE E-Lecture: Subsalt Time-Lapse Seismic for Reservoir Monitoring by David Chalenski

David Chalenski presents a case study using a low-cost but high-data-quality seismic technique to monitor a waterflooded field. This technique, termed i4D, utilizes simple planning methods to decimate a source and nodal receiver patch from a previous full-field survey to monitor the area around a high-risk, high-yield well (such as a water injector) with high accuracy and confidence. He demonstrates that nodal surveys can be targeted even in a highly complex sub-salt field. If planned appropriately, expected data quality is equivalent to a full-field nodal survey. He shows the 4D results and presents business decisions which were influenced using the results of this survey.
