Method of exploitation of a subterranean environment according to an exploitation scheme defined by an optimised representation
Abstract
The invention relates to a method for exploiting an underground environment, in which said underground medium is exploited according to an exploitation scheme defined from a representation of said medium, said representation of said medium being established from a grid two-dimensional representation representing said subterranean medium. The quality of the meshes of said grid is optimized by moving the nodes of said grid by a method of minimizing the deformation of said grid which comprises the following steps:
(1) a reference grid is generated;
(2) imposing a displacement of at least one node, said rigid node, of the reference grid on a corresponding node in the grid to be optimized; and
(3) constructing an optimized two-dimensional grid by moving the other nodes of said reference grid, minimizing the displacement field of said nodes.
