This article continues a series of reviews of the worlds oil and gas basins, where active exploration and development of hydrocarbon deposits in superdeep (6 km +) horizons are taking place, as probable analogues of projects in the Caspian megabasin, primarily the Eurasia project. In this regard the Gulf of Mexico is of great interest, since this region is very well studies over such a long history of its development and thus makes it possible to analyze a huge amount of data collected during this time. The Gulf of Mexico includes the deep-water, offshore and coastal parts of three countries the United States, Mexico and Cuba, and is one of the most important oil and gas provinces in the world. Its deposits are represented by various complexes from the Middle Jurassic to modern sediments, with a total thickness of 14,000 m and more. Exploration for hydrocarbons has been going on here for almost 100 years. During this time, various new technologies have been developed and successfully applied, such as forecasting abnormally high reservoir pressure, cyclostratigraphy and seismic facies analysis, characterization of low-resistivity productive reservoirs and the search for ultra-deep hydrocarbon deposits. Of all the variety of objects developed in the Gulf, in the context of the study of deep deposits, the main interest and possible associations with the Caspian megabasin are the deposits of the Norflet Formation of the Upper Jurassic, which are discussed in the main part of this article. Of course, we are not talking about a direct comparison; in particular, the aeolian origin of part of the section makes this object significantly different. Nevertheless, according to the authors, studying it, as well as understanding how a successful project for its development is being implemented right before our eyes, can provide a lot of important information for working in the deep horizons of the Caspian region. The article is divided into two parts. The first examines the geological history of the formation of the Gulf of Mexico Basin, the features of the deep-lying productive complex of the Norflet Formation. The second part provides information about the history of exploration of the Norflet productive complex, characteristics of the main discoveries, as well as the prospects for discoveries of new superdeep deposits in the Norflet Formation within the Gulf of Mexico (sectors of the United States and Mexico). Analysis of the history of the development of this complex by the global player Shell, is very important, as one of the scenarios for the development of deep horizons in other oil and gas basins, incl. Caspian. International Oil Companies are able to mobilize the necessary resources and technology to effectively address this challenge.

In conditions of high depletion of oil fields and volatile oil prices, methods of enhanced oil recovery are becoming especially relevant, the use of which contributes to an increase in the oil recovery factor in addition to the use of secondary oil recovery methods. One of the technologies allowing to increase the oil recovery factor is polymer flooding technology, the distinctive advantage of which in comparison with other chemical methods is a wide range of application conditions and design variability during implementation. This paper presents the results of the application of polymer flooding technology in the oil field of Kazakhstan Zaburunye, which is in the high water-cut stage. To determine the strategy for the further implementation of polymer flooding technology and in order to find the optimal predictive development options, calculations were carried out on the developed hydrodynamic model.

The article presents the process and results of constructing a three-dimensional geomechanical model of an oil field located in the eastern edge of the Caspian basin. Oil and gas content is established in carbonate deposits of the Lower and Middle Carboniferous. The model was based on well log data, one-dimensional geomechanical models and a 3D geological model. The result of geomechanical modeling is the obtained property of additional permeability of the critically loaded discrete fracture network, which was later used in the history match of the hydrodynamic model. In addition to the fracture property, a series of conductive faults were also identified during the history match. When carrying out geomechanical modeling, international experience was taken into account in the calculation of critically loaded fractures and their relationship with the intervals of inflow and loss in carbonate reservoirs. The updated hydrodynamic model, taking into account the geomechanical model, significantly improved the convergence of the model and historical indicators of bottomhole pressures.

In this article, the author attempted to draw attention to finding and identifying structurally complex reservoir zones in mature carbonate fields, where fractures are of paramount importance. The development of fractured reservoirs of carbonate fields is one of the main areas for boosting production, and most of the significant discoveries took place in described areas. According to the latest calculations, more than 60% of oil reserves and 30% of gas are concentrated in carbonate sediments. Adapting new technologies and transforming the prospecting paradigm makes it achievable to identify fundamentally new areas of research and give an entirely new level of understanding of the geological structure and reservoir properties of mature fields with structurally complex reservoirs. The probability that many of them contain prospects is very high, prospecting and developing these areas that can give them a second life and ensure profitable production.

The aim of the work was to select the optimal reagent for the implementation of polymer flooding in the specific geological and physical conditions of the West Siberian field. For this, the solubility of polymers in the injected water and their rheological properties were studied depending on the shear rate and polymer concentration at reservoir temperature, the dynamic adsorption of polymers on the surface of the porous medium and the coefficient of additional oil displacement with polymer solutions were determined. These works were carried out in accordance with the Enterprise Standard developed by JSC VNIIneft. Based on the results of the physicochemical and filtration experiments, a polymer sample with the best performance was selected. This sample can be recommended for the implementation of polymer flooding technology in the Western Siberia field.
