Hydrocarbon saturation
Hydrocarbon accumulations have been found to mostly occur in pore spaces of reservoir rocks. Therefore, to have an idea of the commerciality of a new accumulation or reservoir, some basic petrophysical parameters such as porosity, permeability, hydrocarbon saturation, and thickness etc., needs to be evaluatedMU_HC cP Calculated Viscosity of Hydrocarbon BO Calculated Oil Formation Volume Factor BP psi Calcualted Bubble Point PHIE v/v Effective Porosity SW v/v Water Saturation SHC v/v Hydrocarbon SaturationAlkanes are also saturated hydrocarbons.

Summary A method to directly invert for poros Fig. 3.34 shows how the capillary number is linked to residual hydrocarbon saturation. Note that x-axis is in the log scale. This trend means that N c has to be increased several orders of magnitude before any impact on residual oil saturation is invoked. However, for basement reservoirs, residual saturation bears a different meaning. Derived properties include porosity (the amount of storage space available to store hydrocarbons), permeability (how well the pores are connected with each other), and water saturation (the amount of pore space filled with water, which can, in turn, be used to calculate hydrocarbon saturation.
