Due to the high relevance of the offshore oil and gas fields’ de-velopment, the authorsexaminethe technology of subsea mining, which is gaining popularity in the Russian Federation. The main types of subsea production system constructions were analyzed and a number of factors, which affect the development of offshore oil and gas fields, were proposed. An algorithm for the software product was created which allows after geo-logical exploration and the discovery of industrial oil and gas recourses to optimize the planning process and to save time and material costs for the company at the preliminary stages of planning. The software product algo-rithm based on such factors asdepth and size of the field, duration of ice season of the region, remoteness of the field from the coast, the level of development of transport infrastructure and the complexity of geological structure.
