Carbon capture and storage (CCS) site screening
Petromod for CCS applications
The latest features added to Petromod software now allow it to simulate CO2 migration from the present day into the future:
- Component injection table.
- Year time step resolution.
- Interfacial tension (IFT) table for CO?.
- Improvement of Invasion Percolation (IP).
Key Applications:
Subsurface characterization:
Petromod helps model the temperature, pressure, and fluid flow history of sedimentary basins, which is crucial for identifying suitable CO? storage sites such as depleted oil and gas reservoirs or deep saline aquifers.
Seal and trap integrity analysis:
The software can simulate caprock integrity and trap mechanisms, ensuring that injected CO? remains securely stored over geological timescales.
Reservoir simulation and capacity estimation:
By modeling porosity, permeability, and fluid saturation, Petromod aids in estimating the storage capacity and injectivity of potential CO? reservoirs.
Risk assessment and scenario testing:
Petromod allows users to run multiple geological scenarios to assess risks such as leakage pathways, fault reactivation, or pressure buildup.
Integration with other data:
It integrates seismic, well, and geological data to create 2D and 3D models, which are essential for accurate CCS planning and monitoring.
