Exploratory, development problems in Paleogene claystone oil fields, central pre-Caucasian basin

This paper reports that the common methods of seismic research and well logging are lacking when used for prospecting for traps and developing claystone reservoirs. Some important details cannot be established because of the limit of vertical resolution of the seismic survey. The traditional method of unlimited horizontal correlation of well-logging curves must be changed by correlating within certain clinoform complexes only. Neither well log data nor the drilling in method (when a negative result is established) indicates the presence or absence of oil saturation.
