The Monte Carlo method

In estimating the ultimate recovery (UR) for an oil reservoir, one would need to use the following:

      UR = Area * thickness * (N/G) * Φ * So * (1/Bo) * RF

      Where:

      Φ is porosity
      So is the oil saturation in the pore space
      Bo is the formation volume factor of the oil
      RF is the recovery factor

            
 

$$ UR = area * thickness * \frac{N}{G} * \Phi * S_{o} * \frac{1}{B_{o}} * RF $$

Where:

  • $\Phi$ is porosity
  • $S_{o}$ is the oil saturation in the pore space
  • $B_{o}$ is the formation volume factor of the oil
  • $RF$ is the recovery factor
