Figure F42. Composite plot of downhole measurements in comparison with petrophysical core measurements (see "Physical Properties") in the basement section in Hole 1243B. gAPI = American Petroleum Institute gamma ray units, IDPH = deep induction phasor-processed resistivity, IMPH = medium induction phasor-processed resistivity, SFLU = spherically focused resistivity measurement, DTCO = T P-wave, DTSM = T S-wave.
