Method for interconnecting geological bodies in a parametric space for simulation of geological reservoirs

A device for interconnecting geological bodies in a subsoil, the device comprising:

• an interface for receiving a first geological body comprising a first parametric surface comprising a plurality of control points and at least one knot vector, and a second geological body comprising a first parametric surface comprising a plurality of control points and at least one knot vector;
• a circuit for determining a low control point among the plurality of control points of the first parametric surface of the first geological body at a low vertical position in the subsoil, and a low control point among the plurality of control points of the first parametric surface of the second geological body at a low vertical position in the subsoil;
• a circuit for modifying the low control point of the first parametric surface of the first geological body in such a way that said low control point corresponds to the low control point of the first parametric surface of the second geological body;
• and
• a circuit for interconnecting the first parametric surfaces of the first and second geological bodies by matching the low control points of the first parametric surfaces of the first and second geological bodies, and by matching each of the at least one knot vector of the first parametric surface of the first geological body with a corresponding knot vector of the first parametric surface of the second geological body.
