WebbNon-useful porosity also occurs as tiny pores that do not connect to any other pores. They are almost invariably filled with immoveable water and do not contribute to useful reservoir volume or energy. Such pores occur in silt, volcanic rock fragments in sandstones, and in micritic, vuggy, or skeletal carbonates. 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 cello luthier ohio michigan

Webb11 sep. 2015 · The first interpretation phase consisted of calculating both the dry mineral volumes such as calcite and dolomite and the total porosity using a matrix solution procedure. For a full suite of lithology and porosity, measurements (gamma ray, sonic, density, and neutron) up to four mineral components plus porosity were calculated. 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. cell old cell phones cashWebbTotal 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. cello master cloth med duty 33x33cm
