1. A method for determination of a real subsoil geological formation, comprising:
receiving a model representing the real subsoil geological formation;
determining a first stochastic trajectory of a first fluvial formation in said model;
defining a constraint zone comprising said first fluvial formation;
determining a second stochastic trajectory of a second fluvial formation in said model within said constraint zone based on a stochastic process;
reiterating the defining the constraint zone and the determining the second stochastic trajectory of the second fluvial formation, and in said reiteration, the second fluvial formation is taken as the first fluvial formation and a third stochastic trajectory of a third fluvial formation is taken as the second stochastic trajectory of the second fluvial formation; and
outputting a complete model to a computing device, the complete model providing data indicating at least the first, second, and third fluvial formations as real subsoil geological formations, which is usable to identify a hydrocarbon reservoir based on the first, second, and third fluvial formations and enable an industrial production plan for production of hydrocarbons based on the complete model.
