Methodology of infogeological modeling for oil and gas fields forecasting

Abstract

Summary The article presents a generalized presentation of the theoretical foundations of information support for research and work on forecasting oil and gas fields of various geological and genetic types. The main working tool of such support is targeted multi-scale information modeling of promising geological objects, based on the general theoretical scheme of the predictive-paleoreconstructive retrospective-static model with the introduction of the concept of formation-material oil and gas accumulation system. It includes cognitive and functional components: primary sources of hydrocarbon components, ways and methods of their transportation, and objects for localization of naphthides. Such a methodological apparatus provides a solution to two predictive and diagnostic tasks: forecasting traps and assessing the potential for their implementation, that is, forecasting deposits. The proposed apparatus is multi-scale, allowing forecasting at the zonal (groups of deposits), local (deposits) and sublocal (deposits) levels. The effectiveness of the presented methodological and methodological developments is demonstrated by examples of targeted modeling of geological objects. Two groups of infogeological models of . promising objects have been developed: the series of Tournaisian Visean productive horizons –areas and the same of Talalayevka area. Several specific recommendations have been realized.
