Overview
Calculations of initial fluids in place (gas, oil and water) is a major priority before estimating reserves. This plug-in calculates the volumes of fluids in place using high-resolution Petrel geological models, porosity, capillary curves and thermodynamic data.
Specifications
  • VolTerra uses Petrel Object to define input data (geological model, capillary pressure curves, fluid properties).
  • Volumetric calculations are performed for black-oil model, including gas condensates. Several PVT representations are possible: Black Oil (BO) with constant bubble point, BO with variable bubble point and dew point.
  • Provides 3D phase pressures at equilibrium.
  • Improves calculations of volumes initially in place for reservoir and surface conditions.
  • Provides 3D saturation grids and saturations along wells.
  • 3D saturation maps help design Maximum Recovery Contact (MRC), and intelligent or smart wells.
Features
This plug-in allows calculation of volumes of hydrocarbons (gas and oil) and water in reservoir and surface conditions. The physics is fully respected. The method is particularly well suited for carbonate reservoirs as it allows considering lateral and vertical heterogeneities.
