1. A method for channel simulation, implemented by computer, comprising the steps of:
- interpreting data characteristic of a complex of channels for a last channel and for a modeled initial channel, wherein the last channel corresponds to a migration over time of the initial channel;
determining, from this interpreted data, points on trajectories running from the last channel to the initial channel, wherein the trajectories correspond to an inverse of said migration; and
simulating at least one intermediate channel running through these points, thereby modeling said migration.

Abstract
A method for modeling turbidite channels which may contain oil that it is desired to extract is provided in which the final shape of the complex resulting from migration of elementary channels over the course of deposition and which is observable from seismic data is combined with the implementation of simple geometric rules, comprising simulation of one or several intermediate channels passing through points on trajectories running from a final channel to an initial channel. The trajectories involved are different from the channel axes or lines; they reflect channel migration over time.

15. A computer program product for channel simulation, the program comprising routines for execution of:
-
interpreting data characteristic of a complex of channels for a last channel and for a modeled initial channel, wherein the last channel corresponds to a migration over time of the initial channel; determining, from this interpreted data, points on trajectories running from the last channel to the initial channel, wherein the trajectories correspond to an inverse of said migration; and simulating at least one intermediate channel running through these points, thereby modeling said migration, when said program is run in a computer.
