Upscaling of a basin model required for pore pressure prediction before and during drilling

A new approach to the basin model upscaling for drilling applications has been described. The approach is based on the composite 3D model of the fluid dynamics in basin time scale. The system analysis and inversion theory have been involved. The work flow of consequent data and model processing has been considering phase by phase. The consequence starts at the 3D seismic data cube where the potential basin model could have M*106 cells to be specified and finishes at the upscaled Earth model given on N*102 cells of optimised non-regular grid. The routine is designated to keep prediction quality at given level at any stage of upscaling. The final Earth model is fully prepared for real time calibration of relevant Earth model and pore pressure prediction / updating of prediction while drilling. The details of the model description and non-local sensitivity analysis have been given in two appendices.
