Advanced Petrophysical Evaluation

To compute & to choose the Right Petrophysical characteristics to avoid overestimating or underestimating of your Oil & Gas reserves and then your NPV.

To determine the Right Cut-offs of Petrophysical parameters by statistical approach to eliminate uneconomic sections

Do you know? In tight low porosity reservoirs, to choose between 5% or 6% as porosity appears as a slight difference but (all other things remaining equal) reserves can change up to more or less 20%. You certainly know very well the impact on the related Economic Indicators NPV & IRR…

Reserves and resources assessment

Reserves volume you use for the Economic Evaluation of your project is strictly controled, first, by Petrophysical parameters such as porosity, water saturation, clay volume, and cut-off to be applied for each parameter.

Our Reserves assessment method is based on:

  • Both Metric and/or Anglo-Saxon system units.
  • Modern concepts and current international standards officialized by  SPE  and  WPC
  • Probabilistic approach using Monte Carlo simulation making possible to know the reserves P10, P50 and P90 and then the MPRV- Maximum Possible Reserves Volume as well as the MERV-Minimum Economic Reserves Volume for the economic evaluation….

We consider the following data as the main parameters controlling the economy of an upstream project:

  • Recoverable Reserves Volume
  • Oil & gas prices & speculation
  • Rate of inflation of the prices
  • Capex & Opex
  • Development cost
  • Operating Cost
  • Transport Cost
  • Abandonment Cost
  • Taxes, …
