Production tomography merges geophysics with reservoir engineering

A unique approach, formulated as a type of waveform inversion, that integrates production data into high-resolution reservoir models with streamline simulators can resolve reservoir heterogeneity utilizing efficient techniques developed for geophysical imaging.The use of a streamline simulator and an associated time of flight formulation make such an analogy to seismic inversion possible.We believe that the streamline-based analytic sensitivity computation and the two-step inversion technique discussed in this article brings the industry significantly closer to production data integration into high resolution models on a routine basis.Although the streamline-based inversion of production ...
