Phit porosity

Webb1 juni 2024 · Unlike the PHIT data, the CCA data cover only those portions of the Thamama-B zone from which cores were recovered. The wells available for permeability study (those with Thamama-B core and for which data were provided for this study) are much fewer than the wells having average wireline-log porosity (PHIT) values. 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
