Porosity simbol
Total porosity The volume of the reservoir rock which is fluid (oil, water, gas) filled, expressed as a percentage or a fraction of the gross (bulk) rock volume. Effective porosity The sum of all the interconnected pore space. In the vast majority of cases, this core analysis and Petroleum Engineering definition of effective porosity equates to total porosity. WebPorosity, given the symbol ϕ, is defined as the ratio of void volume to total rock volume: ϕ = void volume/ (grain + void volume) [2.1] where Vp = pore space volume and Vb = bulk …
