Kapaz field is located in the central part of the Apsheron-Pribalkhan threshold between the Azeri and Livano structures- in the west of the Caspian sea. Water depth changes from 90 m in the east to 130 m in the west, in the area. In the seismic cross-sections of the Kapaz field, deposits from Quaternary to Miocene are observed, the cross-sections were revised using the Ostracoda and Formaninifera fauna contents based on regional well correlations. The tectonic structures are an asymmetric anticline striking NW-SE. The folding undulated the upper Pliocene twice and the middle Pliocene thrice. Secondary undulations present as dome-shaped uplifts (3-5 1.5-2,0 km). The size on the fold in the base of the upper division of the middle Pliocene is 25 x2.5 km. The structure in the base of the upper division of the Middle Pliocene is displaced relative to the structure of the top of the mIddle Pliocene to the northwest along the fol axis 3.5-4 km. Oil and gas potential in the southwestern and northeastern slopes of the structure is associated with the deposits from the suite of Pereriva and also with the underlying suits of PS. Concerning Kapaz field evaluation, it is recommended to drill wells to strip up to the KaS as it was done in the Turkmenistan sector of the Caspian Sea in the Livanova, Gubkina, and Lam field. Taking into account the anomalous high-pressure layer below the suite of Pereriva every effort should be taken to strip up to the KaS successfully
