The INTERSECT high-resolution reservoir simulator is the answer to many of your reservoir challenges. By combining physics and performance in a fit-for-purpose reservoir simulator for your reservoir models, the INTERSECT simulator enables modeling at the scale you need with the physics you need—fast. Reservoir engineers are provided with results that can be trusted to provide insight into understanding the progression of hydrocarbon in the reservoir at a resolution that is otherwise too costly to simulate. The outcome is improved accuracy and efficiency in field development planning and reservoir management, even for the most complex fields. From black oil waterflood models, to thermal SAGD injection schemes, to efficient handling of unstructured grids, the INTERSECT simulator delivers a new approach to reservoir simulation for meeting your reservoir management challenges. The INTERSECT simulator reveals new insights through the efficient simulation of high-resolution models while employing robust physics to support better field development decisions. Detailed reservoir characterization, together with well and network coupling, can be honored with only minimal or no upscaling.

Keep it real: The INTERSECT simulator and Depogrid produce reliable result

Depogrid enables geologists and geomodelers to capture all the different unconformities and changes on the structure of the reservoir with high levels of detail. The unstructured nature of the gridding Depogrid models are simulated by the INTERSECT simulator to capture the effects on fluid flow.

Comparison of pressure drop during the simulation between a pillar grid (left) and Depogrid (right) models

Similar facies distribution but different grid orientation that defines how fluids will flow preferentially. Sequences are defined based on the depositional environment, giving a more geological sense to the final model.
Depogrid models generate consistent and realistic fluid flow along the stratigraphic sequences. Abnormal pressure changes can be seen in the pillar grid model (left) where Depogrid shows a more natural behavior of the pressure.

Find the best well completion: Optimize well completion configurations in one run

The INTERSECT simulator uses advanced completion optimization (ACO) to ensure the flow control valve (FCV) configuration is always operating at its optimum point. Instead of running different cases with different configurations, different parameters of the FCV are optimized by report step, ensuring specific configuration produces the production performance.
