The modeling of hydrocarbon reservoirs and of aquifer-aquitard systems can be separated into two activities: geological modeling and fluid flow modeling. The geological model focuses on the geometry and the dimensions of the subsurface layers and faults, and on its rock types. The fluid flow model focuses on quantities like pressure, flux and dissipation, which are related to each other by rock...

SUMMARY The quality of seismic-to-well tie is commonly quantified using the classical Pearson's correlation coefficient. However the seismic wavelet is time-variant, well logging and upscaling is only approximate, and the correlation coefficient does not follow this nonlinear behavior. We introduce the Dynamic Time Warping (DTW) to automate the tying process, accounting for frequency and time v...

In this work we argue that, from a system-theoretical point of view, there is only a limited degree of freedom in the input-output dynamics of a reservoir system. This means that, for a given configuration of wells in the reservoir, a large number of combinations of the state variables (pressure and saturation values in the grid blocks) are not actually controllable and observable, and accordin...
