Overview
The Shale Volumetrics plug-in extends Petrel to support volumetrics for shale gas reservoirs using geological models of Petrel. The physics is fully respected with Langmuir isotherms to compute the adsorbed gases.
Specifications
  • Supports shale gas reservoirs with different quality of shales
  • Langmuir isotherm definition for each shale types (gas shales and liquid-rich shales)
  • Calculation of in-place free oil and gas, and adsorbed gas
  • Use Petrel objects to define input data (geological model, capillary pressure curves, fluid properties)
  • Volumetric calculations performed for Black-Oil model including gas condensates
  • Various possible PVT representations: Black Oil with constant or variable bubble point and dew point
  • A text report (data & results) provided on a click
  • Integrated with Petrel uncertainty & optimization
Features
Different quality of shales can be considered using 3D spatial distribution provided by high-resolution geological model in facies and porosity built inside Petrel. After calculations of pressures, initial gases in place are calculated in reservoir conditions. The Black-Oil representation of fluids considering liquid-rich gases, initial oil and gas in place are also given in surface conditions.
