Abstract
A method of predicting petrophysical characteristics of an underground reservoir by constructing a geologic model consistent with seismic measurements is disclosed which permits optimization of oil reservoir development schemes. A geologic model, from which seismic data are simulated in depth, is constructed in depth. The geologic model is made consistent with seismic measurements acquired in time by minimization of an objective function by comparing the seismic measurements with seismic data simulated from the geologic model and converted to time. During minimization, the interval velocities used for conversion are updated by comparing, within the objective function, an observed thickness in time ΔTbetween two markers with a thickness in time ΔTsimulated from the seismic data, and by modifying simulation parameters such as the error εon the thickness of the two markers estimated in depth.
