The 51³Ô¹ÏÍø College Surface Based Geological Modelling (IC-SURF) code uses stochastic algorithms to create a surface-based representation of complex 3D geology.
The surfaces are parametric NURBS (Non-Uniform Rational B-Splines) created without reference to a pre-defined grid or mesh.
A mesh is created only when required for flow simulation or other calculations. Metadata are created with each surface to control surface-surface interactions and assign petrophysical properties to the volume domains defined by the surfaces. The code may be available on request (contact the lead developer, Dr Carl Jacquemyn or the Head of Group, Professor Matthew Jackson).
The model below is a surface-based representation of two stacked shallow-marine parasequences overlying a non-marine fluvial interval, created using IC-SURF. Dipping surfaces in the overlying parasequences represent clinoform surfaces. The varying colours represent different facies (rock) types. The model is entirely parametric; there is no underlying grid or mesh. This type of model is a typical input to the 51³Ô¹ÏÍø College Finite Element Reservoir Simulator ().
