Abstract
Summary
A quantitative method for assessing the performance of a water injector is proposed, using well-centric metrics derived from 4D seismic data. Amplitude analysis is performed to give estimates of sweep efficiencies and injected fluid flow directions in swept areas of the reservoir. The methodology is applied to injectors in a UKCS oil field. For each injector in the field, the calculations are guided by the use of synthetic seismic data and flow simulation models. The results are in broad agreement with expectations for the field production and alignment described by the directions of sediment deposition.
