Using a unique gridless model building framework, RokDoc ChronoSeis enables rapid 3D-4D geological modelling and reservoir monitoring. Models integrate structural and stratigraphic information, data from wells and seismic, and reservoir simulation results enabling users to analyse evolving reservoir behaviour.
Reservoir Modelling
Rather than store properties on a geocellular grid, RokDoc ChronoSeis uses a continuous chronostratigraphic age field as the model foundation. All other model features such as depth surfaces, rock properties, fluid contacts and well data are date-stamped and can change with production time.
Model properties are stored as recipes and calculated on-the-fly meaning:
Reservoir Monitoring
Thanks to the underlying gridless, time-varying model, RokDoc ChronoSeis is ideal for 4D seismic reservoir monitoring. Seismic surveys on varying geometries can be combined together with data from well logs and reservoir simulation to enable workflows including:
Close the loop between the geomodel, 4D seismic and reservoir simulation.
