Abstract: A method of determining a migration pathway of a subterranean fluid through a geological volume is provided. The starting object is located within the geological volume. The starting object defines an initial fluid boundary. Data points are distributed through the geological volume. The data points are associated with values of one or more geological attributes. The method includes the steps of: defining an expression which determines a change in position of the fluid boundary at the data points over an iteration based on the values of the one or more attributes; and applying the expression at the data points for successive iterations to evolve the fluid boundary over the successive iterations. The migration pathway of the subterranean fluid through the geological volume can then be determined from the evolution of the fluid boundary.
