Abstract

Geologic model building of the subsurface is a complicated and lengthy process. Seismic data are usually inverted at the beginning of this process and discarded after inversion and interpretation. Modifications from the seismic inversion results are almost never validated due to the one-way information flow towards reservoir properties. In this paper, we propose to include the production data and the inverted reservoir properties back in the seismic inversion during the next iteration of geologic model updates. The elastic properties and the fluid-flow properties are connected and cross-updated based on the underlying rock physics models. The statistical approach we propose in this paper not only provides a single Earth model that best satisfies both types of data, but also has the potential to properly quantify the uncertainty associated with this model. We show preliminary results from the proposed framework on a synthetic gaspocket identification example.
