Intersect Latest Features
Decline curve modeling
You can now seamlessly generate decline curves and couple them with reservoir and network models, for faster integrated scenario evaluation.
A new decline curve modeling workflow is available. It can replace a reservoir model with a set of decline curves that simulate the individual performance of wells. Decline curves can be generated from a base reservoir simulation or provided externally, and then replace rigorous reservoir simulation.
The decline curves seamlessly interact with complex field management logic and can be used in coupling models in conjunction with multiple simulation and network models.
Decline curves perform orders of magnitude faster than a rigorous simulation, making them ideal tools for scenario evaluation and optimization.

Intersect 2021 Features
Machine learning-enabled reservoir simulation
A machine learning (ML) framework is implemented in the Intersect simulator, allowing the introduction of data-based intelligence into reservoir simulation. From new physics to faster computations, the possibilities are limitless.
In the first of many workflows, we have introduced an alternative phase-labeling method for better prediction of fluid behavior in the simulation. It relies on critical temperature estimation, enhanced by neural networks. As a result, better physics can now be introduced in the simulator, at a fraction of the computing cost.

CO2 Storage Physics
The Intersect simulator is being developed with state-of-the-art methods for CO2 storage modeling. In 2021 we have focused on modeling the Joule-Thompson effect, simple geochemistry, and mass transport.
Three key developments have been introduced in Intersect to enhance the CO2 storage simulations—superheat enthalpy tables to model pressure and temperature dependency of enthalpy, solid phase for isothermal compositional simulation to model basic geochemistry through chemical reactions, and intra-phase diffusion to model mass transport.
