摘要:
A method and system for conciliating hydrocarbon reservoir model data. In one implementation, a set of local permeability values of a reservoir and an apparent permeability value of the reservoir are provided. A power value is numerically calculated from a mean power formula that relates the apparent permeability value of the reservoir to the local permeability values of the set via the power. The calculated power value is compared with a reference value. Depending on the outcome of the comparison, the set of local permeability values is modified.

摘要:
A method, program and computer system for changing scale of reservoir model permeabilities (for example a hydrocarbon reservoir) are provided. Mini-models of reservoirs are defined (S100) with a number of meshes and cells in these meshes. For each model mesh, a scaling of the permeability values KH of the meshes is carried out (S400-800) via a mean power formula KHωH ∝ΣkHiωH relating the mesh permeability KH to the local permeabilities kH,i of the cells. According to the invention, the power coefficient ωH appearing therein is analytically modified, relatively to its expression given by the Noetinger-Haas relationship, in order to correct a non-ergodicity bias.

The present invention relates to simulating modifications to the mineralogical compositions of soil. This simulation includes: simulating a stochastic movement of a particle in a geological model and modifying the mineralogical composition attached to the model. This modification is based on at least the coordinates for the particle in the model, the aggressiveness of the particle, and the local mineralogical composition. As a result, the aggressiveness of the particle is also modified.
