BasinMod

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.

BasinMod Fact Sheet

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.

BasinMod allows the user to model the volume of hydrocarbon generation and expulsion through time for multiple wells for both conventional and unconventional resource plays. A wide range of other values are modeled including maturity, porosity, permeability, pressure, and temperature, all of which can be used to further analyze the petroleum system. In addition to the capabilities already present in BasinMod, the current release of BasinMod further aids the user in quickly solving problems for both unconventional and conventional resource plays.

Capabilities:

  • Trigger Maps – Depth to or age of a specified occurrence
  • Mineral mixes
  • Erosion Estimator (Sonic Log or Vitrinite Trends)
  • Pore pressure predictions and excess pressure
  • TOC, Initial TOC, HI, TMAX
  • Porosity, generated hydrocarbon volumes
  • Expanded Heat Flow database
  • Log cross-plots
  • Improved log display/selection

Unconventional Resource Modeling

Unconventional resource plays differ from conventional plays with respect to the problems to be solved and the parameters to be considered. In these plays, organic shales must be assessed both as source rocks and reservoirs. Source rocks with  great potential will not be economically viable if they aren’t producible. The URM for BasinMod provides specifically designed capabilities to evaluate these parameters. For more on the features of URM please click here.

BasinMod Bridge

Using Bridge, BasinMod models can be created by dragging and dropping various data from industry-standard databases, such as Petra® or IHS® 297 into BasinMod. All known incoming data formats are supported. For more on the features of BasinMod Bridge please click here.
