Fig. 2. Measured and calculated physical properties for Well C1A. Property vs. depth curves are, from left to right, measured He porosity of 2.5 by 2.3 cm basalt sample cores (blue), neutron log response on a linear scale in API-N units (red), - (long-spacing) log response on a linear scale in cps (purple), measured bulk density of sample cores in grams per cubic centimeter (black), and the natural log of measured sample core permeability in millidarcies (red). All units increase to the right except for bulk density.
