Highlighted below are some of the significant features which are common to TS&E's reservoir simulation software.

Ease of Use: All input data are keyword based in free format and independent of the order in which they are read within a major group of the data. Data templates and Excel based GUI (for some simulators) are provided to facilitate data preparation for new users. Experienced users can gain familiarity in a matter of hours to begin undertaking serious studies. Bulk of the data for commercially available simulators can be converted into our format with ease and minimal efforts. Free unlimited support is available via email and telephone to assist in the data preparation task.

Output and Post-Processing: Output in tabular, graphical, and 3-d images may be requested for all relevant reservoir and well performance parameters. 3-d visualization via OpenDX (IBM sponsored software package) and Surfer (Golden Software Co.) may be optionally employed. Excel based x-y graphs for well, reservoir, gathering stations, and reservoir sectors/segments may be produced. Live graphs as simulation proceeds may also be requested for certain key variables.

A Host of Well, Gathering Station, and Reservoir Constraints: Wells may be produced/injected at a specified rate of oil, gas, total liquid, or water. Bottomhole or wellhead pressure constraints my be specified to limit the rates. Also a group of wells may be connected to a gathering station where the total gather station rate is specified and the simulator will internally allocate the rate to individual wells. In a couple system, the rate and pressure at the delivery point of a transmission system may control the individual well rates.

Unstructured Grid and Faults with Non-Neighboring Grid Connections: Any arbitrary size, shape and grid orientation may be defined for grid blocks. Facility is provided to internally generate the desired data when local grid refinement or inter-fault flow to non-neighboring blocks are desired. Illustrated is a sample of a few choices for local grid refinements with IFVD Formulation Labels f and g for representing wells, l for horizontal wells, a and b and e for Cartesian grid refinement.

Single Porosity, Dual Porosity/Permeability Fractured Reservoirs: All simulators can accommodate any user defined anatomy of the rock including dual porosity, dual permeability, multiple interacting continua (MINC) and special cases of dual permeability distribution.

Fully Implicit or Semi-Implicit formulations: Simulators are based on fully implicit formulations with option to reduce the degree of implicitness to implicit pressure and explicit saturations/temperature.

Robust and Efficient Linear Equation Solvers: Options of D-4 ordered direct method, Nested Factorization techniques, ILU factorization with GMRES and Bi-conjugate stabilized algorithms ensure efficient computational speed regardless of the complexity and size of the system.

Built-in Correlations and Default Values: A number of correlations for relative permeability data, hydrocarbon properties, steam and water properties, turbulence of gas flow around wells, and a number of other correlations are internally supplied which may be overridden at user’s discretion.
