Summary:A method of generating a depositional sequence volume from seismic data (100) is performed at a computer system having one or more processors and memory storing programs to be executed by the one or more processors. The method includes the following steps: receiving a seismic dataset (212), wherein the seismic dataset (212) includes image values at a plurality of grid points (301) of a 3-D subsurface model; identifying reflections (104) at a first subset of the plurality of grid points (301) and geological constraints (102), such as fault planes, at a second subset of the plurality of grid points (301) of the 3-D subsurface model from processing the image values of the seismic dataset (212); and generating a depositional sequence volume (216) for the 3-D subsurface model from the reflections (104) at the first subset of grid points (301) and the geological constraints (102) at the second subset of grid points. Dirichlet or Neumann boundary conditions are applied around faults or discontinuities found on the g
