Integration of Multi-Scale Data for Search and Exploration of Oil and Gas Fields

The article is devoted to the complex coordination of multi-scale multi-level data obtained at different stages of geological exploration, in order to create a single ordered model of the deposit, taking into account retrospective and modern research results. The search for oil and gas fields in sedimentary oil and gas basins involves a classic scheme from the general to the particular. Therefore, when determining the oil and gas potential of the territory, regardless of the stage of geological exploration, it is necessary to determine the boundaries of the location of the local object in the regional plan and build a structural framework for the main reference strata (reflecting horizons). Based on the structural framework, paleostructural reconstructions are carried out to restore the stages of trap formation and determine the migration paths of fluids. Based on the data of geophysical well surveys and core studies, reservoir intervals are established, the properties of lithotypes are identified and secondary processes of reservoir rock transformation are determined. Geochemical and hydrogeochemical studies of fluids are conducted to identify fluid-dynamic connections within a sedimentary basin, oil and gas accumulation zone, field, and individual deposit. Geomechanical studies are performed to apply modern development methods. All obtained data are integrated with each other, allowing new patterns to be identified, thereby increasing the reliability and efficiency of geological exploration.
