Our expertise covers the wide range from basic review of asset valuation to a detailed estimate of the proven, probable and possible reserves, as well as the contingent and prospective resources if any, on a technical and economic basis.

  • Log Interpretation – NTG, porosity, HC saturation
  • PVT interpretation – Formation Volume Factor
  • Well test, production and reservoir pressure analysis – Recovery factor
  • Volumetric, material balance, decline curve analysis methods
  • Reservoir simulation deck (mainly Eclipse) audit
  • Development scenarios audit
