Phit porosity
WebbTotal porosity includes the bound water in the shale and is called PHIt. Effective porosity does not include bound water, and is called PHIe. When there is no shale, PHIe equals PHIt. Logs read total porosity. All our analysis methods correct for shale, so the answers from any method presented below will give effective porosity. WebbPorosity represents the rock’s capacity to trap fluid. It is the main quality indicator for hydrocarbon-bearing reservoirs. The reservoir porosity is a crucial input to estimate …

Webb2. Total Porosity The estimation of total porosity is done by averaging the porosity computed from RHOB (Bulk Density) and NPHI. The equations are as under: PHID = (RhoM – RHOB) / (RhoM – RhoF) Where RhoM = matrix Density, 2.71 gcm3 RHOB= Bulk Density RhoF = Fluid Density, 1 PHIT = (PHID + PHIN) / 2 Where PHIT = Total Porosity
