Two types of porosities can exist in a rock. These are termed primary porosity and secondary porosity. Primary porosity is described as the porosity of the rock that formed at the time of its deposition. Secondary porosity develops after deposition of the rock. Secondary porosity includes vugular spaces in carbonate rocks created by the chemical process of leaching, or fracture spaces formed in fractured reservoirs.

19), Cwe is expressed in terms of Cw and a function of shale (in the shale model) or a function of clay (in the clay model). In Eq. 20), X is a function that accounts for the conductivity caused by shale or clay that occur in shaly sands. Note that in Eq. 20) as X approaches zero, Eq. 20) becomes equivalent to Eq. 18). The main point to note from Eqs. 20) is that total porosity is an important data input for calculation of water saturation with water saturation models. If errors exist in the calculations of total porosity, these errors will be transferred to the calculation of water saturations.

He has published numerous technical papers on chemical and petroleum engineering topics. Nnaemeka is a registered professional engineer in California and Texas. 1 Introduction Porosity is defined as a measure of the capacity of reservoir rocks to contain or store fluids. The fluids stored in the pore spaces within the reservoir rocks could be gas, oil, and water. High porosity values indicate high capacities of the reservoir rocks to contain these fluids, while low porosity values indicate the opposite.
