Abstract
Experimental investigations of Pliocene clays in the Baku Archipelago have noted that the persistence of montmorillonite content to 6200 m is connected with predominance of the process of secondary montmorillonite formation from illite over the process of primary montmorillonite destruction. Based on the mechanism of interrelation and reciprocal influence of clayey-mineral transformation and thermobaric conditions of the sedimentary basin, the author has developed a method for computer prediction of filtration-capacity parameters for terrigenous sedimentary rocks taking into account the influence of thermobaric, lithological-mineralogical, structural, and geotectonic factors. For zones of abnormally high pore pressure and temperature decline, the Southern Caspian Depression (Basin), is a good example where the possibility of montmorillonite preservation to 15–17 km may indicate the probability for discovery of commercial hydrocarbon accumulations at depths of 9 km.
