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. \u0000The 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. \u0000Of 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. \u0000The 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.","PeriodicalId":17771,"journal":{"name":"Kazakhstan journal for oil & gas industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74909371","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. \u0000When 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.","PeriodicalId":17771,"journal":{"name":"Kazakhstan journal for oil & gas industry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74790335","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
