Gas/Oil Interfacial Tension
Gas/Oil Interfacial Tension correlation was published by Baker and Swerdloff in 1956.
Math and Physics
The density of formation water (brine) at reservoir conditions:
Nomenclature
- = water formation volume factor, res bbl/STB
- = water salinity or solids concentration, mg/l
- = water density at standard conditions, lbm/ft3
