Siam Geotest presents an update to the SiamWellTest 2.1.0 software suite. The new release significantly expands the product's applicability by introducing numerical simulation tools for solving hydrodynamic analysis tasks.
1. Numerical Simulator Integration
The PTA (Pressure Transient Analysis), RTA (Rate Transient Analysis), and pressure/rate generation modules have been enhanced with numerical flow simulation capabilities. This allows for detailed consideration of reservoir geometry and spatial heterogeneity of properties.
Features of the numerical approach implementation:
- Detailed geometry handling: modeling of objects with arbitrary boundary shapes, internal faults, and spatial heterogeneity of reservoir properties (porosity/permeability).
- Performance and efficiency: high calculation speed achieved through adaptive grid generation algorithms and modern fast solvers.
- Solution verification: demonstrated high convergence of simulation results with both known analytical solutions and benchmark solutions from recognized numerical simulators.
2. Map Module Functional Development
The Map module has been transformed into an interactive editor for constructing simulation schemes, which serve as the foundation for generating numerical simulation grids.
- New objects: functionality has been added to place faults, reservoir boundaries, and wells with common completion types and wellbore trajectories on the scheme.
- Parameterization: a system for defining physical properties for each scheme element has been implemented, along with input fields for general parameters of the modeled reservoir.
- Interface and navigation: a redesigned toolbar structure makes the scheme construction process faster and more intuitive.
3. New Comparison Module
The suite now includes a Comparison module for rapid comparison of data from different parts of the project.
- Versatility: the tool allows comparison of any tabular and graphical project data, including raw measurements, PVT analysis results, and final interpretation models.
- Visualization: supports data comparison in both graphical and tabular views.
- Dynamic updates: the module operates in real time, instantly reflecting any changes to data or scenarios within the project.
