Abstract

Summary

Surface-based reservoir modelling for hydrocarbon or geothermal reservoirs is a modelling approach that represents subsurface heterogeneity by surfaces. All heterogeneity of interest is modelled only by its bounding surfaces, free from a predefined grid. This overcomes grid-related limitations of conventional modelling approaches such as stair-stepping, loss of connectivity or continuity and resolution limitations to capture small features that are essential to flow.

Creating surface-based models relies on generating 100's of surfaces of different geometries, scales and relationships, all representing a boundary between volumes with different properties. We show how adding metadata to every surface enables automatic assembly of all these individual surfaces into a surface-based reservoir model. Metadata signifies why a surface exists and includes what properties are on either side of a surface, which volume it intersects and the level of detail it represents. Multiple model realisations can now be built automatically from stochastically generated bounding surfaces.
