A modern assessment of the technical and economic efficiency of an oil and gas project involves the construction of a certain economic and mathematical model of calculation, as well as an analysis of project criteria based on a variety of forecast economic indicators for the developed formations and the field as a whole. The automated system developed for this purpose served as the basis for theoretical and applied research in the field of economic modeling and modern information technologies. The article shows that with the help of modern information technologies it is possible to represent formalized knowledge (facts), the truth or falsity of which can be proved. In particular, these methods can be used in the digital economy of subsoil use. At the same time, it is supposed to analyze the processed information on the options for field development in order to solve the problem of synthesizing computational algorithms. Involvement of "systems engineers" in calculations significantly reduces the modeling process. The knowledge bases have been developed over the past two decades and are based on the experience of the technical and economic assessment of oil and gas fields both in our country and abroad. The system allows forecasting the technical and economic indicators of the study and development of hydrocarbon objects, taking into account various tax mechanisms, as well as assessing the value of deposits and the effectiveness of their development using fuzzy methods for assessing the risks of investment forecasts. It provides prompt and high-quality performance of technical and economic calculations for numerous options and sub-options with the choice of the optimal solution that determines the strategy and forecast for the development of oil production with different sources of funding. This development can be a good addition to the already existing software systems for the technical and economic assessment of the effectiveness of the development of oil and gas fields. It is relevant that the bipartite graphs that are part of the developed automated system make it possible to visually enter and correct technical and economic information on field development options.
