Fig. 2.6 Comparison of porosities and wet bulk densities measured on discrete samples and by electrical resistivities.
Boyce’s (1968) values for the coefficients (a) and (m) and pore fluid and grain densities of 1.024 g cm
-3 and 2.67 g cm
-3
were used to convert formation factors into porosities and wet bulk densities. Wet and dry weights and volumes were
analyzed on discrete samples. (a) Cross plots of both data sets for square barrel kastenlot core PS2178-5. The dashed
lines indicate an error of 10% for the porosity and 5% for the density data. (b) Porosity and wet bulk density logs of
core PS2178-5 derived from resistivity measurements. Superimposed are porosity and density values measured on
discrete samples. Data from Bergmann (1996).
