Marine seismic surveys of 2D common depth point method (CDP) in the Kizlyar Bay of the North Caspian were carried out by the YuMNG trust and later by CJSC "Geo-Khazar" in 1991–2004. They included the development of reconnaissance, regional profiles and a network of seismic profiles corresponding to the exploration stage of work, and later, development of a detailed network of 2D CDP profiles in the marine and transit-shallow water zones for linking marine and coastal seismic data.
Based on specialized dynamic processing of 2D CDP materials, their complex reinterpretation has now been performed. On the studied area in the transitional pre-Jurassic complex, promising objects associated with the deposits of the Neftekum suite were identified. Their parameters have been detailed. Recommendations are given for setting up deep exploratory drilling and further seismic surveys on the Tyuleneostrovnoye northern uplift of the Tyuleniy license site area.
