* Φ = porosity (decimal, not percent)
* Φ = porosity (decimal, not percent)
* S<sub>w</sub> = water saturation (decimal, not percent)
* S<sub>w</sub> = water saturation (decimal, not percent)
* B<sub>oi</sub> = formation volume factor = 1.05 + (N × 0.05), where N = number of ft<sup>3</sup> of gas produced per bbl of oil (gas-oil ratio [GOR]). For example, if a well has a GOR of 1,000, then B<sub>oi</sub> = 1.05 + (10 × 0.05) = 1.1.
* B<sub>oi</sub> = formation volume factor = 1.05 + (N × 0.05), where N = number of ft<sup>3</sup> of gas produced per bbl of oil ([http://www.enggcyclopedia.com/2012/03/gas-oil-ratio-gor/ gas-oil ratio [GOR]]). For example, if a well has a GOR of 1,000, then B<sub>oi</sub> = 1.05 + (10 × 0.05) = 1.1.
