123D Sim & Vis 4.0 Key Features
(First Principles Basin Modeling)
- Multi-component petroleum diffusion and migration considering transient changes in structural geometry,
free and adsorbed film phase distribution, and other disequilibrium effects caused by e.g.
viscous flow in an anisotropic porous medium;
- Reservoir analysis tool for quantifying oil, gas, and condensate reserves based on user
defined demarcation criteria of reservoir properties;
- Pathway display showing petroleum exodus of source rock, migration through carrier bed,
and accumulation in reservoirs using colors to time the event or identify the fluid component with a label;
- Point & click interface for defining present day stratigraphy via import of Zmap-files
assigning depth to top horizons;
- Robust finite volume numerical scheme for optimal handling of fluid mass diffusion migration and
heat conduction and convection.
123D Sim&Vis allows the user to build a basin model from chrono-stratigraphic subdivision of key events,
lithological composition of layers using pre-defined rock-end-members, and description of present day
stratigraphy assigned through layer-thickness or depth/two-way-travel time to top horizons. The
point-and-click user interface handles data from any seismic interpretation software, which is capable
of exporting datasets in ZMap format.
User controlled simulation features of 123D Sim&Vis:
- Compaction: viscous flow of minerals induced by prolonged impact of effective stress or from
porosity-effective stress rocktype-curves;
- Hydrological evolution: hydrostatic pressure or compaction driven pressure build-up with or
without disequilibrium effects coupled or decoupled to petroleum migration. Option to calculate
brine residence time for demarcating meteoric regime pertinent to diagenesis;
- Thermal history: vertical 1D or full 2D/3D conduction incl./excl. convection incl./excl.
radiogenic heat sources. Option to generate paleo-surface temperature by tracking plate
movements and correcting for paleo-sea depth. Option to generate paleo-basement heat flow
by coupling lithospheric heat flow model incorporating isostatic determination of Moho
boundary, radiogenic heat generation in and thermal conduction through lower crust and
upper mantle;
- Maturation: Arrhenius-type kinetics with discrete suites (Behar 2010/ LLNL 1991/ IFP 1987/ IFP 1975/ user-defined)
or Gaussian distributed activation energy for conversion of algal, liptinic, and humic kerogen.
Optional choice of sequential n-component modeling or single-step non-compositional modeling
of heavy hydrocarbon cracking down to light hydrocarbon. Option to calculate vitrinite
reflectance, transformation of biomarker, and fission track annealing;
- Hydrocarbon system: n-component hydrocarbon diffusion and migration considering equilibrium between
adsorbed film (2) & free (3) phases, and first principles derived PVT-fluid properties incl. viscosity,
interfacial tension, molecular diffusion coefficients, and texture dependent properties incl. capillary pressure, and free
phase drag forces.
Optional batch generation mode ignoring hydrocarbon migration. Option to generate
distribution of kerogen-type from paleo-sea depth and near-surface preserved TOC from
sedimentation rate.
123D Sim&Vis utilizes dynamic timestep-control, optimized numerical scheme with respect to minimizing
computation times, and sparse-matrix solvers - iterative or direct.
