Despite the fact that the area is in a long-term development, its prospects are closely related to the refinement of the geological structure and the study of the section of productive deposits. The complex tectonic structure of the structures located in the northwest of the Absheron archipelago does not allow for an accurate determination of the boundaries of the distribution of deposits, including the Qala suite. For this article, new structural maps were compiled based on a comparison of numerous geological and geophysical profiles and well logs. The areas of distribution of sedimentary deposits of QaS have been clarified, and drilling of an appraisal (exploratory) well 1202 has been proposed in order to clarify the tectonic structure of the area. Keywords: Reservoir; Sediment; Fault; Well; Block; Overthrust; Correlation.

New polyacrylate, polyethylacrylate, Poly-2-hydroxyethylacrylate polymers were synthesized and their effects on the parameters of drilling fluids were studied. It was found that the addition of 0.2% of polymers reduced the free water of the solutions. One of the advantages of this polymer is that it is effective in different environments (both acidic and alkaline). These polymers also retain their weight at high temperatures. Keywords: Polymer; Monomer; Polysaccharide; Oligosaccharide; Polyphosphate.

Azerbaijan is one of the oldest oil and gas producing regions in the world. Industrial development of oil fields has been started here since the second half of the 19th century. The article examines the current state of the fields that have been under development for a long time and identifies modern problems. Solutions to these problems have been explored. Our research objects are Darwin Bank, Pirallahi Island and Gurgan-Deniz fields on the Western Absheron-South anticline line. All three fields have been under development for a long time and have sufficient residual reserves. The study of the current state of oil and gas fields, which have been under development in our country for a long time, shows that it is necessary to take the right approach to identifying ways of efficient use resources. During the development process, the geological parameters of oil and gas fields are subject to certain changes. These changes can be both regular and in various forms. Issues that are important for the effective completion of the long-term development of oil and gas fields which we researching have been studied and identified. Geological-geophysical data were collected and systematized to clarify the structural-tectonic, lithofacial features and substantiate the ways of effective development of resources. The geological structure and structural tectonic features of the deposits have been clarified and structural maps have been compiled. 3D geological model of the deposits has been compiled, lithofacial features have been determined and lithofacial model has been constructed. The characteristics of tectonic faults were determined, the reserves were redefined and geological risks were assessed. Keywords: Field; Geological model; Structural map; Productive series; Development; Exploitation.

The role of the process of fractional crystallization in the formation of Neogene volcanism in the central part of the Lesser Caucasus is discussed in the article. It was found that in the formation of rocks of the andesite-dasite-rhyolite association found in the central part of the Lesser Caucasus, the role of rock-forming minerals in intermediate foci - plagioclase, clinopyroxene, amphibole, olso titanium magnetite, apatite is quite large. Based on computer modeling, it was determined that the calcium-alkali trend of the andesite-dasite-riolit series is controlled not only by the fractionation of magnetite, but also by the crystallization of hornblende with a high Fe/Mg ratio and unsaturated with SiO2. Hornblen's early crystallization is a key factor in the formation of the calc-alkaline series during the evolution of Neogene magmatism. Keywords: Central part of the; Lesser Caucasus; Neogene volcanism; Fractional crystallization; Hornblende crystallization.

The article is devoted to the evaluation of hydrocarbon reserves and resources with new approaches of Productive Layer sediments in the Azerbaijan sector of the South Caspian Basin. In the research work, hydrocarbon reserves of the oil and gas and gas condensate fields of the SCB were calculated by Monte Carlo method and distribution regularities on cross-section have been studied. Hydrocarbon resources in the basin were evaluated using a completely new approach-unconventional method. The proposed approaches are very important in determining the sequence of exploration work in such basins and in formulating the exploration strategy of the field. Keywords: Basin; Reserve; Resource; Exploration; Field; Formation; Bayes method.

The Zardab – Shikhbagi area is located on the northeastern slope of the Yevlag – Agjabedi depression and on the southeastern wing of the Saatli – Goychai uplift zone. Based on the conducted geological and geophysical, research and data from exploration drilling, it was established that in the geological structure of the Zardab-Shykhbagi area, deposits from Quaternary to Lower Cretaceous inclusive are involved. The article commented on some data from 3D seismic surveys carried out at Zardab - Shykhbagi and related fields. The changes in the parameters of seismic waves are analyzed on the basis of time and dynamic depth sections drawn up in different directions. In accordance with various stratigraphic sections, intervals were identified and they were interpreted. Based on the performed studies, the presence of favorable geological conditions for the formation of anticline and non–anticline traps, which can be considered promising from the point of view of oil and gas potential at the Zardab - Shikhbagi field, was predicted. Keywords: Seismic exploration; Oil and gas potential; Time section; Dynamic and deep section; Anticline and non-anticline traps.

In the AzII named after Azizbekov conducted studies of the physico-chemical properties of clay solutions prepared on seawater and reservoir water. The article considers the influence of these properties on the quality of clay solution. It was found that the clay solution prepared on reservoir water has better qualities compared to the clay solution prepared on seawater. It is shown that the need for chemical reagents for processing clay solution prepared on reservoir water is reduced by 20-50%.

The article is devoted to determining the laws that govern the movement of fluid from the well into the reservoir and back. To study this pattern, the authors conducted experiments on a circular model. Based on the analysis of the experimental results, the following pattern was revealed: when a certain amount of liquid is injected into the reservoir, significantly less repression is required than depression is required when the same amount of liquid is taken from the reservoir. From what has been said, it can be concluded that the pick-up coefficient in all cases is significantly higher than the productivity coefficient. In addition, a certain pattern has been revealed between reservoir pressure and pressure gradients in the bottom-hole zone of the formation. This pattern also lies in the fact that the lower the reservoir pressure, the greater part of the total depression falls on the bottom-hole zone of the formation. This suggests that outside the bottom-hole zone of the formation (critical zone) at low pressure, the value of pressure gradients is insignificant. Therefore, a significant part of the pressure gradients falls on the critical zone. Of course, the work done does not pretend to be a complete study, but it nevertheless shows that the influence of local resistances must also be taken into account in hydrodynamic calculations. Keywords: Fluid movement; Filtration from the formation into the well; Infiltration into the formation; Bottom-hole zone of the formation; Critical zone; Modeling.
