Abstract

The work reflects the experience of studying and developing carbonate deposits of the Osinsky, Yuryakhsky and Preobrazhensky horizons located within the Nepa arch and the Nepa-Botuoba anteclise. During the study, the actual data obtained from drilling exploration, prospecting and production wells, the results of core material studies, formation fluid and the interpretation of 3D seismic exploration materials were summarized. The article provides a brief overview of published works, based on the results of which an analysis of all accumulated available geological, industrial and laboratory information was performed, and a unified conceptual model of the geological structure of the layers of the Osinsky, Yuryakhsky and Preobrazhensky horizons and the conditions of their formation was constructed. The work proposes a methodological approach to selecting a strategy for developing carbonate formations in Eastern Siberia.
