The concept of Earth Recursion is introduced to solve critical problems of Shared Earth Model builders especially related to their capability to express the geological evolution. The recursive approach turns out to be very efficient when addressing apparently diverse questions like natural “aging”, property depth trends, incorporation of externally defined property distributions, faults within volumes and structural restoration. The concept is implemented in the Compound Earth Model builder by StatoilHydro. It is shown how the original expression for spatial distribution of properties can be written as a recursive sequence. This revision forms the basis for the implementation of Earth Recursion in the builder and demonstrated by construction of a complex property distribution reflecting the interference of on-lapping features, normal faulting and compression.
