DEVELOPMENT OF LOW PERMEABLE RESERVOIRS AT THE PRIOBSKOYE FIELD (WESTERN SIBERIA)

Abstract

The main problem in the development of the Priobskoye field is the search and implementation of technological solutions for the most efficient development of layers of ultra-low permeable reservoirs. A factor complicating the hydrocarbon production for such facilities is the low impact of flooding. These restrictions lead to high rates of decline in oil production, therefore, the most urgent issue is the search for an up-to-date technological solution aimed at improving the efficiency of field development. This article is devoted to improving the efficiency of the development system in areas with low filtration and capacitance properties. It presents the results of research on the study of the construction of horizontal wells longitudinally and transversely to regional stress, followed by multi-stage hydraulic fracturing in the conditions of one of the largest fields in Western Siberia. The results of the research made it possible to determine an effective strategy for designing development systems in future areas. The relevance of this work: the demand for the extraction of hard-to-recover reserves from reservoirs characterized by low permeability.
