PeREV is developed for volumetric calculations using limited reservoir data. Both deterministic and probabilistic methods are available in PeREV. Monte Carlo and Latin Hypercube sampling can be used for quantification of uncertainty in porosity, water saturation, rock volume and fluid properties data.

Some features of PeREV include:

• Calculation of oil and gas in-place by volumetric methods
• Volume versus depth method for calculation of in-place volumes
• Reserve estimation using probabilistic methods (MC & LHS)
• Quantifying uncertainty in reserves using Monte Carlo simulation
• Common probability distribution functions for reservoir properties
• User defined distribution functions
