Core-plug bulk densities were used to recalibrate both whole-core and downhole bulk density logs. Core-plug measurements of matrix density permit conversion of the whole-core and downhole bulk density logs to porosity. Both velocity and formation factor (a normalized measure of resistivity) are strongly correlated with porosity. The velocity/porosity pattern is similar to that for the lower part of CRP-2A and is consistent with the empirical relationship for sandstones. Core-plug and whole-core measurements of P-wave velocity at atmospheric pressure exhibit excellent agreement. Measurements of velocity as a function of pressure indicate a significantly higher velocity sensitivity to pressure than has been observed at CRP-1 and CRP-2A; rebound or presence of microcracks at CRP-3 may be responsible. The percentage difference between velocities at in situ pressures and atmospheric pressures increases downhole from 0% at the seafloor to 9% at the bottom. This pattern can be used to correct whole-core velocity data, measured at atmospheric pressure, to in situ velocities for depth-to-time conversion and associated comparison to the seismic profile across the drillsite","descriptionType":"Abstract"},{"description":"Supplement to: Jarrard, Richard D (2001): Petrophysics of core plugs from CRP-3 drillhole, Victoria Land Basin, Antarctica.
