BasinMod 2-D

BasinMod 2-D models dynamic geologic conditions within a petroleum system, by examining hydrocarbon generation from source rocks through secondary migration and accumulation in traps.

Model building:

• Easily handle complex stratigraphy, including complicated unconformities.
• Vary surface temperature and heat flow through time.
• Model lateral and vertical facies successions.
• Graphically display and edit chronostratigraphic section.

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.
• Uses finite difference method for thermal and fluid flow calculations.
• Fluid flow along faults may be or automated or manually controlled.
• Calculate effects of mobile substrates (e.g.,salt, shale) 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.
• Measured maturity, porosity, temperature and pressure may be displayed on the cross section for calibration.
• Draw a burial history or plot any model value versus time or depth.
• Display velocity arrows for oil, gas and water.
