The article reviews the analytical generalization of lab-scale data on petrophysical parameters of potential hydrocarbon reservoir rocks. The study objects were the known levels in the pay thickness of the Mesozoic–Cenozoic sedimentation basin. The test territory included dynamically and longterm operating inland and offshore oil and gas projects in Azerbaijan. More than a century-long history of these natural hydrocarbon reservoirs shows that the prime oil and gas pools are associated with the South Caspian and Kura depressions subjected to intense subsidence in the Mesozoic–Cenozoic era. Despite the long-term exploitation of the depressions, the deep-level reservoirs are highly commercially promising. At the same time, the challenges of oil and gas extraction in these areas yet remain pending. Currently, high-rate subsoil development in this region is carried out at the depths below 4–4.5 km since the shallow and moderate-depth oil and gas reservoirs are already explored even in difficult ground. The oil industry terms wells longer than 4 km as deep and longer than 6 km as super deep. Aside from engineering difficulties, drilling of such wells involves grand economic problems. For instance, deep and, moreover, super deep drilling cost is very high and ranges from 2–3 to 9–12 million dollars. This fact necessitates improvement of drilling efficiency, which requires highquality geological validation of promising nature of a deposit and reasoned selection of drilling sites.
The reported study was funded by RFBR according to the research project №18-55-06002.
