OIL AND GAS POTENTIAL OF THE MIOCENE DEPOSITS OF THE ZYKH FIELD BASED ON 3D SEISMIC DATA

The article is devoted to the prospects for oil and gas potential of one of ancient fields of the Absheron Peninsula of Azerbaijan, the Zykh field. The geographical location of the Zykh deposit is described, it is noted that deposits of the upper and middle Absheron are exposed here, and a section of the Pliocene deposits has been opened by wells. The main objectives of the research were determined and the task was set, which states that numerous wells were drilled in the Zykh area under study and geophysical work was carried out by various methods, despite this, many issues of the deep tectonics of the territory and the conditions for the formation of oil and gas deposits have not been fully explicated. The Zykh field is at a late stage of development and currently has only one production well. In order to expand the resources of this field, recommendations were prepared for drilling based on 3D seismic data from prospecting appraisal well No. 2. When choosing options for the location of deep exploration wells in the Zykh field, the entire volume of seismic material was analyzed, as well as cubes of seismic attributes, both mono-attributes and complex ones. When performing an analysis of the information content of seismic attributes, extinctions and spectral energy were selected. The article notes that the conducted studies have shown that the prerequisites for oil and gas potential on the eastern slope of the Zykh uplift are the existing favorable regional conditions for the development of the oil system. As well as local favorable conditions, which consist in the presence of a shielding thickness, elongated in the submeridional direction. We attribute the presence of a steep eastern slope of the Zykh uplift to negative factors. It is also indicated that the main production facilities are expected in the Miocene and Kalinskaya formations, but there are certain geological risks and they are listed.
