    摘要: The present disclosure relates to a method for determination of real subsoil geological formation characterized in that the method comprises:
    /a/ receiving a model representing the real subsoil,
    /b/ determining a first fluvial geological formation in said model using parametric surfaces,
    /c/ determining a subsequent fluvial geological formation as a deformation of the first fluvial geological formation using parametric surfaces,
    /d/ subtract the first fluvial geological formation from the subsequent fluvial geological formation to create a new geological formation named point bar formation.

    摘要: The present disclosure relates to a method for determination of real subsoil geological formation characterized in that the method comprises:
    /a/ receiving a model representing the real subsoil, said model comprising a shore line (1000) and a fluvial formation (1003) connected to said shore line at a point (1006) of the model, said shore line dividing the model into a marine zone and a continental zone,
    /b/ determining a delta zone in the model based on the shore line and based on the fluvial formation,
    /c/ determining a stochastic trajectory in said delta zone,
    /d/ determining a lobe formation in said delta zone based on the determined stochastic trajectory based on a stochastic process.

    摘要: The present disclosure relates to a method for determination of real subsoil geological formation characterized in that the method comprises:
    /a/ receiving a model representing the real subsoil, said model comprising a stratigraphic layer, said stratigraphic layer comprising a shore line (800) dividing the stratigraphic layer into a continental zone (801) and a marine zone (802);
    /b/ receiving a first flow speed field (811) representative of a continental domain for the stratigraphic layer;
    /c/ receiving a second flow speed field (812) representative of a marine domain for the stratigraphic layer;
    /d/ determining a weighted combination, named global flow speed field, of the first flow speed field and the second flow speed field for each position in the stratigraphic layer, weights of the combination are based on a distance of said position to the shore line (800) and the fact that the position is within the continental zone or the marine zone;
    /e/ determining a real subsoil geological formation for the stratigraphic layer based on the determined global flow speed field.
