Subsurface modeling has provided numerous challenges to the reservoir characterization community over the years. As more data become available, it has become progressively more difficult to evaluate the interpretation results from each of the disparate disciplines represented. One of the most recent advances in data acquisition is the implementation of permanent downhole gauge (PDG) data, both for electronic flow meters and continuous-readout bottom-hole pressures. This kind of information provides real-time monitoring of the physical reservoir response to dynamic fluid-flow conditions resulting from production.

The significant challenge for the geoscience team is to construct a geologic and numerical simulation model that...
