Underground medium e.g. petroleum deposit, exploiting method, involves optimizing exploitation of underground medium based on values of petrophysical properties assigned to hexahedral meshes in geographical mark

摘要

The method involves defining a simulation grid formed of hexahedral meshes, and modeling the covariance of a property to be simulated to evaluate spatial variability of the property in an underground medium. A function for transporting the covariance of a geographical mark into a regular mark is evaluated. A geostatistic simulation is realized in the grid from the transported covariance. The grid in the geographical mark is transported using the function. The exploitation of the medium is optimized based on values of petrophysical properties assigned to the meshes in the geographical mark.
