Abstract
This paper presents an approach that integrates pressure transient and multi-component seismic data to determine the characteristics of single- and double-porosity reservoirs. It is shown that a functional dependence exists between the well-test-determined storage capacity ratio and the seismic estimate of the normal fracture compliance. This functional dependence provides a means to obtain an estimate of the normal fracture compliance from well-test data or an estimate of the storage capacity ratio from seismic data. Obtaining estimates of these parameters by independent means helps reduce the nonuniqueness problem encountered in the interpretation of well-test or seismic data by reducing the number of parameters to be determined. In addition, it is shown that assuming a fracture model, the fracture density may be predicted from the storage capacity ratio. The application of the approach developed in this work is demonstrated by the analysis of the pressure buildup data from the Weyburn Field.
