Painting for geomodeling

A non-transitory data storage medium having recorded thereon a computer program comprising instructions for performing a computer-implemented method of geomodeling, the method comprising:

• providing a pseudo-stratigraphic grid representing a reservoir and having pillars, each pillar including respective cells, each cell having a respective stratigraphic layering index;
• providing a surface having a first region and a second region, the second region being complementary to the first region;
• for each first pillar intercepted by the first region, determining a respective first stratigraphic layering value based on relative position of the surface in the first pillar, the determining comprising computing a proportion of the first pillar above the surface;
• and
• for each second pillar intercepted by the second region, determining a respective second stratigraphic layering value by at least one of interpolating and extrapolating first stratigraphic layering values;
• the non-transitory data storage medium being configured to be used in a process, the process comprising performing one or more iterations of the method and performing one or more physical actions on a geological environment based on a result of the one or more iterations of the method.

A system comprising a processor coupled to a memory, the memory having recorded thereon a computer program comprising instructions for performing a computer-implemented method of geomodeling, the method comprising:

• providing a pseudo-stratigraphic grid representing a reservoir and having pillars, each pillar including respective cells, each cell having a respective stratigraphic layering index;
• providing a surface having a first region and a second region, the second region being complementary to the first region;
• for each first pillar intercepted by the first region, determining a respective first stratigraphic layering value based on relative position of the surface in the first pillar, the determining comprising computing a proportion of the first pillar above the surface;
• and
• for each second pillar intercepted by the second region, determining a respective second stratigraphic layering value by at least one of interpolating and extrapolating first stratigraphic layering values;
• the system being configured to be used in a process, the process comprising performing one or more iterations of the method and performing one or more physical actions on a geological environment based on a result of the one or more iterations of the method.
