Subsoil Formation Determination via Global Flow Velocity Field

The patent inverts the traditional workflow by performing modeling first and meshing afterward. Instead of meshing the model before analysis, the method generates an unmeshed model, performs the modeling operations to determine geological formations, and then creates the mesh based on the results. This inversion eliminates the biases introduced by pre-meshing while maintaining the ability to initiate and complete the modeling process.

The patent applies preliminary action by defining the geological model structure, sedimentary bodies, and formations through modeling operations before creating the mesh. The unmeshed model allows geological formations to be identified and defined with accuracy, and only after this preliminary modeling is complete is the mesh generated to match the determined geological structures.

The patent inverts the traditional approach by satisfying well constraints during the unmeshed modeling phase before meshing occurs. Log data and well constraints are applied to the unmeshed model where full precision is maintained, allowing accurate satisfaction of constraints. The mesh is then generated afterward to match the already-constrained geological model, avoiding the need for blocking methods that would reduce data precision.

The patent performs the association of cells with facies and geophysical properties as a preliminary action after modeling but before final mesh generation. In the unmeshed model, geological formations and their spatial relationships are identified with high precision. The mesh and cell associations are then created based on these precisely identified formations, ensuring that positional relationships are properly maintained while enabling model analysis.
