Migration

This flow path modeling program (2.5-D) combines source rock and carrier bed data with hydrodynamics to model oil and gas migration and entrapment potential at the prospect, play, or basin level.

  • Defines migration pathways and fetch areas.
  • Identifies structural, stratigraphic, fault, hydrodynamic, and combination traps.
  • Calculates oil and gas accumulation in traps.
  • Models trap fill and spill.
  • Models the impact of groundwater recharge/discharge on migration and entrapment.
  • Simulates loss of hydrocarbon during the migration or through seal leakage.

Migration Dynamics:

  • Buoyancy drive caused by variations in structure and the density differences between hydrocarbons and formation water - predicts structural traps.
  • Capillary drive caused by variations in oil-water capillary pressure, which is a function of permeability - predicts stratigraphic and fault traps.
  • Water drive caused by groundwater flow - predicts hydrodynamic traps.

Output:

  • Display Migration output as maps through geologic time in BasinView.
  • Draw maps of traps, migration pathways, and fetch areas.
  • Display vector maps of buoyancy, capillary, and hydrodynamic drive.
