Abstract

The description of a reservoir internal architecture in Reservoir Engineering needs seismic acquisitions and well tests. They provide us with information about the petrophysical parameters of the underground, such as permeability and the acoustical impedance. Numerical simulators are used to reproduce these events: the wave equation for the seismic experiment, and the fluid flow modelling. Then, inverse methods are used to fit the calculations with the observations, through the update of the parameters. Unfortunately, a lack of data often deteriorates the results. Thus, linking the permeability and the impedance to add information in each area, a simultaneous inversion of the two problems has been managed, which improves significantly the recovery of the both parameters. Technical aspects and numerical results are presented here, with a validation of the method on a synthetic case.
