Model the volume of hydrocarbon generation and expulsion through time for multiple wells. Both conventional and unconventional resource plays can be modeled. A wide range of other values is modeled including maturity, porosity, permeability, pressure, and temperature, all of which can be used to further analyze the petroleum system.

Burial History:

• Model complex stratigraphy, including unconformities
• Select from several calculation methods for compaction, porosity, and permeability
• Model porosity by mechanical, fluid flow, or chemical compaction
• Mix lithology or mineral components to create an unlimited number of custom lithologies
• Model changes in formation thickness due to salt or shale movement (diapirs).

Diagenesis and Pressure:

• Calculate pore fluid pressure to predict the timing and/or depth of abnormal pressure regions as well as subsequent fracturing
• Enhance porosity reduction by means of quartz cementation in the sand and smectite-illite conversion in shales.

Thermal History:

• Model thermal maturation and predict the timing of hydrocarbon generation/expulsion
• Model basement heat flow, radiogenic heat flow, and rifting heat flow
• Vary surface temperature and heat flow through time.

Logs:

• Drag and drop logs in LAS format
• Display logs adjacent to stratigraphy column for formation top editing
• Pick porosity points from a porosity log for use in calibration.

Source Rock Organic Richness:

• Determine Total Organic Carbon (TOC) from logs of resistivity and porosity
• Calculate Initial TOC

Maturity:

• Use several maturity indicators for calibration, such as %Ro, TMAX, TAI, and CAI.

Kinetic modeling of hydrocarbon generation:

• Model one component of oil and gas using simple LLNL kinetics or organofacies kinetics (Pepper and Corvi, 1995).
• Model multiple components of oil, gas, and residue using compositional kerogens
• Access a library of kerogens compiled from literature including multiple variants of Types I, II, and III.

Erosion:

• Estimate the amount of surface erosion using a sonic travel time log.

Output:

• Spatially display any calculated or measured value using a variety of color and contour options
• Display shapefiles of cultural or hydrographic data
• Display radar plots that compare several calculated values against an ideal case
• Generate standard and continuous color burial history plots
• Plot any calculated value versus time or depth
• Plot any calculated value or measured data against any value or data
• Generate log-log cross-plots
• Display geochemical logs of pyrolysis data.
