WebJun 24, 2015 · The shallow penetrating density log may be reading entirely from the invaded zone, where mud filtrate (not gas) fills the porosity. With luck, the neutron … Web2. Non-equilibrium fluctuation theorems applied to organisms. FTs concisely describe stochastic NEQ processes in terms of mathematical equalities [70,71].Although FTs were initially established for small systems, where fluctuations are appreciable, they also apply to macroscopic deterministic dynamics [].Here, we present FTs in an appropriate context of …
WebFormation bulk density provides a key measure of porosity. The bulk den-sity (rhob or ρ b) of a formation is based on the ratio of a measured interval’s mass to its volume. In … WebDec 6, 2024 · The caliper log indicates the change in the diameter of the borehole with depth and can be used as an indicator of the quality of other logs whose data have been degraded by the enlargement or shrinkage of the borehole wall. Damaged well-log data, particularly density and velocity profiles, affect the quality and accuracy of the well-to …

Hence, the partial concentration of hydrogens per unit volume(C H) vol = r bwater/9 = 1/9, because the density of pure water is 1.000 g/cm3. Now, theHydrogen Index of a material is defined as the partial concentration of hydrogens per unit
