Abstract:
1. A method for predicting production of an underground reservoir, including generating a parameterized geologic model from measurements of seismic data in time and measurements of production data, comprising: a) using a computer to simulate dynamic production data from the geologic model and a flow simulator providing flow simulations; b) using a computer to simulate a petro-elastic model in depth from the geologic model and the flow simulator; c) determining a depth/time conversion model; d) converting the petro-elastic model in depth into a petro-elastic model in time; e) using a computer to simulate the seismic data in time from the petro-elastic model in time; f) using a computer to perform an optimization process comprising iterations, to optimize the geologic mode by comparing at each iteration, with an objective function, the simulated dynamic production data and the simulated seismic data in time, and by updating at each iteration at least the depth/time conversion model; g) starting again from a) until a minimum is obtained for the objective function; and h) predicting the production of the underground reservoir from flow simulations provided by the optimized geologic model.
