text: Meanwhile, according to (2), the porosity to time [t.sub.i] can be calculated as shown in Table 4.
text: "Porosity" is never a measurement, it is a calculation.
text: Porosity can be calculated if bulk density and particle density are known.
text: Porosity is calculated is the ratio between the pore volume of a medium and its total volume, and it is expressed as n=Vv/Vt.
text: Neutron log is, I personally think, is the worst of all; first, the porosity generated from neutron is calculated based on certain matrix type, sandstone or limestone, thus it is fixed; unlike density, where you can actually give "special" matrix density suppose you have routine-core analysis data (RCAL) data.
