Cretaceous Deposits

Although the Outer zone of the Precarpathian foredeep is one of the oldest gas extraction regions of Ukraine it is still promising for the exploration of new oil and gas deposits. The main gas deposits are open here in the Miocene, but the number of unidentified structures is rapidly shrinking. The development of unexplored Cretaceous deposits and the possibility of opening up their deposits of oil and gas can provide an increase in the resource base. In this case, the importance of the prospects of oil and gas bearing capacity of Cretaceous deposits is determined by a set of criterion features, including the determination of the nature of collectors and caprocks distribution, the establishment of favorable hydrogeological, structural and tectonic conditions for the formation and conservation of oil and gas deposits. The substantiated oil and gas prospect increases the search engine success, and therefore the development of the hydrocarbon potential of the Cretaceous deposits of the Outer zone can make a significant contribution to the fuel and energy supply of Ukraine with its own raw materials. Generalization, systematization, and analysis of new and reinterpretation of previously performed geological and geophysical studies and the results of deep drilling made it possible to substantiate the reliable geological structure of the cretaceous deposits of the studied region, which will increase the efficiency of prediction of oil-and-gas saturation and determine the priority oil and gas prospecting objects for detailed geological and geophysical works in order to search for new oil and gas deposits. Research results will increase the efficiency of search work, and the growth of promising and projected resources will be a significant contribution to the task of stabilizing and increasing oil and gas production in Ukraine.

Energy independence is an important component of sustainable development and security of the state. Ukraine has a great hydrocarbon potential of the subsoil, which is why the priority objective is a search and exploration of new deposits of hydrocarbon raw materials. One of the important directions for increase of potential resources and reserves of oil and gas is the development of large deep (over 4500–5000 m) deposits, as hydrocarbon reserves at small and medium depths are quite depleted in many regions. For a long time, hydrocarbon reservoirs in basement rocks were underestimated during geological exploration works. Obtained results indicate that new concepts of the formation of hydrocarbon deposits can dramatically change the system of oil production, methods of prospecting and development of deposits. It is important to assess possible oil-and-gas-bearing capacity of sediments and rocks of the basement by identifying prospective areas of hydrocarbon deposits, including in the rocks of the crystalline basement. In Ukraine, main prospects of discovery of oil and gas deposits at great depths are associated nowadays with the Dnieper-Donets Rift (DDR). Deposits with accumulations of hydrocarbons at depths of more than 5000 m are concentrated in the main oil-and-gas-bearing areas of the Rift that coincide with the central paraxial and marginal zones of the graben. It was in the central segment of the DDR that the main regularities of oil-and-gas-bearing capacity of deep-lying geological formations were first discovered: secondary nature of reservoirs, discovery of the phenomenon of supercollectors and associated huge debits. It is relevant and promising to study the process of recovery/replenishment of gas reserves by the example of deposits that are at the final stage of development.

New Vision

The article reviews the results of the next re-interpretation of geological and geophysical material of Airakty gas condensate field located in Zhambyl region of Kazakhstan. Despite rather good prospects of oil and gas bearing of the region, quite a long period of geological and exploratory research, and discovered and developed fields, the study is extremely low, and the efficiency of geological and exploratory works here remains low. Therefore, the resource base for gas production remains insufficient to supply the region. Therefore, an attempt was made to examine the structure and oil and gas content of one field in this region from the point of view of non-anticlinal traps (NAT). This provides a new insight into the internal structure of the field and allows to clarify its geological structure and adjust the prospecting methodology in the direction of NAT deposits. The applied technology of re-interpretation of geological and geophysical material by approbation of neural training algorithms on the basis of new well data, synchronous prestack inversion (which is currently actively used in the exploration industry as part of the standard interpretation graph) allowed to take a new look at the peculiarities of the internal structure of rocks composing the productive part of the section, to highlight, in particular, isometric "bodies", which have been interpreted as incised river systems, e.g., isometric "bodies"

The article discusses the geological structure, oil‐and‐gas‐bearing capacities and salt tectogenesis of the Anabar‐Khatanga saddle located on the Laptev Sea shore. In the study area, the platform sediments are represented by the 14‐45 km thick Neoproterozoic‐Mesozoic sedimentary complexes. The regional cross‐sections show the early and middle Devonian salt‐bearing strata and associated salt domes in the sedimentary cover, which may be indicative of potential hydrocarbon‐containing structures. Diapirs reaching the ground surface can be associated with structures capable of trapping hydrocarbons, and typical anticline structures can occur above the domes buried beneath the sediments. In our study, we used the algorithms and software packages developed by A.A. Trofimuk Institute of Petroleum Geology and Geophysics (IPGG SB RAS). Taking into account the structural geological features of the study area, we conducted numerical simulation of the formation of salt dome structures. According to the numerical models, contrasting domes that reached the ground surface began to form in the early Permian and developed most intensely in the Mesozoic, and the buried diapirs developed mainly in the late Cretaceous and Cenozoic.

Oil And Gas Production

It is necessary to carry out work to analyze the harmful factors of accidents during the production, operation and transportation of raw materials in oil and gas fields and assess their compliance with the requirements of the standards of the Republic of Kazakhstan. The main goal of labor protection is to create safe working conditions for employees, as well as to prevent personnel from illnesses. In this regard, it is necessary to have a system of accounting, analysis and assessment of the state of labor protection, as well as management of labor protection. This article proposes ways to quickly assess the state of health and safety at work by calculating a number of occupational risk indicators based on information available in the modules for assessing occupational safety by industrial risk indicators. The efficiency of using the OSH management systems software proposed by the authors is based on a specific task from four main modules "Employees", "Events", "Equipment", "Ecology" and a number of submodules. In addition, this work uses matrix methods for assessing risks in the "Probability or Consequences of an Event" coordinate system, "Elmeri" system, "Fine Kinney" method, "Risks". Modern expert methods are compared and presented under the title "Five stages of assessment"
