Disclosed is a method of modelling a subsurface volume, and a corresponding computer program and apparatus. The method comprises defining a regular planar grid of regularly arranged locations in the two dimensions substantially parallel to the surface, and calculating a plurality of one dimensional arrays 210, each one dimensional array extending from a different one of the regularly arranged locations, in the direction from surface to subsurface. Each of the one dimensional arrays comprises a plurality of one dimensional cells 220, wherein the cells are delineated according to actual geological features of the subsurface volume. The cells may be delineated by subsurface faults and/or boundaries 230 of subsurface layers in the dimension perpendicular to the planar grid. The grid is thus a hybrid grid which is regular in the x and y direction in a similar manner to a seismic grid while maintaining the irregular layered approach in the z direction of a reservoir grid. |
