ECLIPSE 2013 is a major release of the ECLIPSE industry-reference reservoir simulator, hosting new features and enhancements to existing capabilities in ECLIPSE Blackoil simulator, ECLIPSE Compositional simulator, and FrontSim Streamline simulator. The release also continues to develop integrated workflows with Petrel Reservoir Engineering.
Modeling of chemical EOR processes
The addition of polymer to injected water decreases its mobility and hence reduces viscous fingering and improves sweep efficiency. The ECLIPSE Blackoil Polymer model has been extended to enable the modeling of advanced polymers and gels, including temperature-sensitive “popping” polymers. As polymer floods through the rock it adsorbs to the surface and reduces its permeability to water. This effect is accurately modeled using a residual resistance factor in the ECLIPSE simulator, which now integrates temperature and rock properties dependency.
Improved characterization of shear effects in the ECLIPSE 2013 polymer model provide more accurate, robust, and stable modeling of viscosity changes due to flood velocity.
Surfactant offers a way of recovering residual oil by reducing the surface tension between the oil and water phases. A Surfactant model has been added to the ECLIPSE 2013 compositional simulator—this models surfactant effects on miscibility, adsorption onto the rock, and change in wettability resulting from adsorbed surfactant. The model can be used together with the existing Compositional Foam model.
Simulation of unconventional reserves
In coalbed methane simulation, coal shrinkage is modeled using the Palmer-Mansoori rock compaction model. This model has been enhanced in ECLIPSE 2013 to improve simulation speed and enable rapid diagnosis and isolation of problem areas.
For shale oil and gas reservoirs modeling in ECLIPSE Blackoil and Compositional simulators, the enhanced rock compaction models support better modeling of directional permeability changes in the rock matrix. This enables improved modeling of heterogeneous compaction effects and hydraulically fractured wells.
Water alternating gas (WAG) hysteresis model
WAG hysteresis modeling capabilities have been extended to allow the characterization of two-phase and three-phase water saturation regions. This improves the robustness and supports the coexistence of conventional and WAG hysteresis saturation functions to enhance the predictability of gas and fluids behaviour in WAG operations.
Advanced well modeling
ECLIPSE 2013 now supports the complete shutting of multiple completion types, such as valves and inflow control devices, to isolate branches of the well while allowing for crossflow in the isolated branches. The 2013 Petrel E&P software platform provides the modeling, visualization, and configuration of the sliding sleeve device for simulation cases. Simulation of the sliding sleeve device is then done using this new functionality in the ECLIPSE simulator.
Streamline simulation
The enhancement to the saturation functions in the ECLIPSE FrontSim Streamline simulator activates the Leverett J-Function to scale capillary pressure based on rock porosity and permeability, on a saturation region-by-region basis.
Waterflood management now supports user-defined solvent allocation among a set of injectors. Result analysis has also been improved to include report data for pattern-based solvent efficiency.
