摘要： Disclosed is a method of determining front propagation within a subsurface volume such as a reservoir. The subsurface comprises a plurality of cells and at least one geological fault (210). The method comprises performing a fast marching algorithm so as to determine said front propagation in terms of the time of arrival of the front at a particular cell from one or more neighbouring cells which make up the neighbourhood of said particular cell. For each faulted cell (C) that is adjacent a geological fault, the neighbourhood of the faulted cell is defined as comprising only its geometric neighbours (NS, NG cells and NG cells) where the geometric neighbours are those cells that are in contact with the faulted cell in a geometric sense, regardless of stratification.
