Algorithm for substantiating facilities selection for introduction of oil production innovative technologies in the conditions of the lower cretaceous deposits of Western Siberia. Bulletin of the Tomsk Polytechnic University. Geo Аssets Engineering, 2023, vol. 334, no. 10, рр. 179-186. In Rus. The research relevance due to significant residual oil reserves, concentrated in Cretaceous deposits of the West Siberian oil and gas province, which require the creation of innovative oil production technologies. The important issue in this case is the selection of facilities for experimental industrial work. The main criterion for such selection is the maximum possible analog facilities availability, which will allow efficient technologies replication to improve the technical and economic indicators of facilities with a significant amount of hard-to-recover residual oil reserves. The aim of the research is to create an algorithm for selecting oil production facilities in the conditions of the Western Siberia fields for innovative technologies implementation. Methods: geological and commercial analysis, methods from the image recognition theory when processing geological and commercial material arrays for deposits that have been in development for a long time. Results. The authors proposed an algorithm for selecting development facilities for implementation of innovative technologies at the Lower Cretaceous facilities of the West Siberian oil and gas province. The algorithm was created based on the use of geological and physical parameters of formations affecting predominantly oil recovery. This algorithm creation is based on as well on the formulated criteria that the facility must satisfy (a significant number of facilities analogous to the landfill one in terms of the geological structure and formations and fluid properties affecting to the greatest extent the technical and economic indicators of the deposits development; presence of significant residual or not actively involved in the development oil reserves in analogue deposits; presence of facility identification algorithms, which allow establishing the facilities identity degree and assessing risks when applying new technologies in the conditions of analogue facilities). The selection of polygon objects is proposed to be carried out in three variants: within oil and gas-bearing areas, within stratigraphic systems, within tectonic elements, depending on the requirements of the subsurface user. The obtained algorithms make it possible to select objects for replication of positive practices, as well as to increase the success of the implementation of innovative technologies.
