This invention relates to a method for determining a location of karst caves in a geological model. The method comprising for each current point of a set of points of a closed space of the model, determining a distance value; receiving an average value; and for each current point of the set of points of the closed space, determining a presence of caves for the current point. The determination at the presence of caves depends at least on the received average value and on the distance value determined for the current point. A collapse procedure can also be implemented as described in the description.

Method for determining geological caves

The present invention relates to a method for determining a karstic region modified by karstification phenomena. This method comprises, from a geological model, determining a seed cell and a target cell in that model. If a distance between the seed cell and the target cell is above a given distance, it is possible to update the seed cell with a bifurcation cell based at least on the coordinates of the seed cell, the coordinates of the target cell, a distance distribution, an angular distribution, and to re-iterate the test. Based on that bifurcation cells, trajectory is computed and cells of that trajectory is updated with new cell characteristics.

Method for determining a karstic region

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.
