owing to the greater volume of water squeezed from the shales, mudstones, and/or
marls into the associated reservoir rocks.
This suggests the following predictive techniques: (1) increase in the resistivity of
shales; (2) decrease in the acoustic travel time of shales; (3) increase in the bulk density
of shales; and (4) decrease in the pulsed neutron capture cross-section of shales (Fertl
and Chilingarian, 1989).
Considerable amounts of research work, however, still remain to be done in this area.
