Extended multi-carrier modelling software

The functionality of the Semi3D multi-carrier hydrocarbon migration modelling software package has been extended. The modelling software now incorporates fault capillary properties calculated from fault offsets and the nature of the faulted stratigraphy. The software has been extended to incorporate spatially variable stratigraphy and temporal variation in fault seal capacity due to changes in the density of the trapped hydrocarbon phases.

A representative wells approach has been implemented using “well areas”. An interpolator calculates the distances to the nearest wells all over the study area and combines this with the grids of horizons (for stratigraphic control) to provide variable fault seal attributes on all faults within the model area.

The software extension is complete, using parallel computing via MPI, and is now able to account for fault seal between carriers of different age when modelling the migration of oil and gas into traps in a multi-carrier system.

The extended version of Semi3D provides hydrocarbon explorations with an improved tool for incorporating all of the available wells into migration models.
