Abstract
The equilibrium saturation distribution in a petroleum reservoir prior to production is governed by the pore space characteristics. This happens as a result of non-wetting phase fluid (hydrocarbons) entering pore space initially occupied by wetting phase fluid (water) during migration of hydrocarbons from a source rock region into a reservoir trap. A pressure differential is required for non-wetting phase fluid to displace wetting phase fluid and this is equivalent to a minimum threshold capillary pressure and is dependent on pore size.
