BasinMod 2-D

Product Overview

Model the entire petroleum system from source rock to trap.

BasinMod 2-D features true 2-D pressure with generation pressure, time-transgressive events, 3-phase fluid flow, predictive faulting, basement heat flow, radiogenic heat flux, rifting heat flow, and salt movement.

Product Features

Model building:

Import data including BasinMod 1-D files, digitized or scanned cross sections, Landmark and GeoQuest project files.
Create and edit cross sections using powerful drawing tools.
Easily handle complex stratigraphy, including complicated unconformities.
Create facies changes by assigning different lithologies to points on the cross section or by drawing facies overlays.
Mix pure lithologies from the on-line lithology library to create new lithologies.
Enter lithologies as depositional environments, seismic facies, A-B/C sequence stratigraphic analysis or lithofacies.
Graphically display and edit cross section in age.
Graphically vary salt thickness history through time.

Calculations:

Calculation engine combines backstripping and forward modelling.
Calculate values for all cells in a calculation grid.
The variation of pressure and fluids in adjacent cells drives migration.
Define a uniform calculation grid; add divisions in areas of interest. The program also adds divisions where higher resolution is required, such as along faults and time transgressive events.
Uses finite difference method for thermal and fluid flow calculations.
Graphically define, edit, and vary surface temperature and heat flow through time.
Model facies changes with gradational changes in rock property values rather than abrupt changes at facies boundaries.
Control faulting or model faults predictively.
Model changes in salt geometry through time.

Output:

Display model values, such as temperature, pressure, maturity, generation, and saturation in cross section either as continuous color or value windows at any point in time.
Quickly view values through time using age slider bar.
Enter measured values, such as for maturity, porosity, temperature and pressure, at well locations. These data may be displayed on the cross section for calibration.
Draw a burial history plot for any point on the cross section.
Plot any model value versus time or depth for any cell in the cross section.
Display colored flow arrows for oil, gas and water.
Generate hardcopy using Windows® device drivers; export CGM in ZEH® Graphics format.
