Fluid Saturations • Definition - The fluid saturation for a particular fluid is the fraction of pore volume occupied by that fluid – Saturation is an intensive property – Equations: S o =V o /V p , S w =V w /V p , S g =V g /V p • These fluid volumes are measured under specific conditions of pressure and temperature (e.g. reservoir, or laboratory) – reservoir conditions are often noted as “ in situ

Fluid Saturations • Fundamental Relationships – Pore volume is occupied by fluids (water, oil, and/or gas) • for the two phase case, only one of the two saturations is independent, the other must make the sum of the saturations equal to unity (1) • similarly, for the three phase case, only two saturations are independent g o w p g o w g o w p S S S V V V V 1 V V V V + + = + + = + + =

Fluid Saturations • Fundamental Relationships (continued) – The mass of the fluids in the pore volume is comprised of: water, oil, and/or gas • at laboratory conditions it is often assumed that gas density is negligible [] g g o o w w p g g o o w w g o w S ρ S ρ S ρ V V ρ V ρ V ρ m m m mass fluid + + = + + = + + =
