Specialists of LLC RN-KrasnoyarskNIPIneft (part of the corporate research and design complex of Rosneft) have developed a technology for processing 3D seismic data, which opens up new opportunities for developing hard-to-recover hydrocarbon reserves. The technology successfully justifies itself where standard seismic approaches are ineffective. The innovation helps to reliably investigate fields with carbonate reservoirs that make up at least 20% of the Company’s recoverable reserves, and to improve drilling efficiency by an average of 5% of this category of fields. In the future, the applied technology will also allow increasing the volume of recoverable hydrocarbons.
The introduction of advanced approaches and new technologies is one of the key areas of the Rosneft-2022 strategy. The company pays special attention to innovative development, identifying technological leadership as a key factor in competitiveness in the oil market.
The innovative technology consists in the extraction of a special component – scattered seismic waves from standard 3D seismic data – with their subsequent interpretation. The analysis of scattered waves is of great importance in the exploration and development of complex carbonate reservoirs and provides the detection of hydrocarbon accumulation zones in fractured rocks.
During the development and testing of the technology, advanced algorithms of wave seismic modeling were used, which make it possible to recreate the processes occurring in a real geological environment using a mathematical approximation. Within the framework of the project, 2 patents for technologies and 10 computer programs were registered.
The technology is currently being actively used at the Yurubcheno-Tokhomskoye and Kuyumbinskoye fields of the Company’s subsidiaries in Eastern Siberia.
LLC RN-KrasnoyarskNIPIneft is an integrated regional research and design institute supporting the activities of key Rosneft Companies in Eastern Siberia (Krasnoyarsk Territory, Irkutsk Region, Republic of Sakha, Yakutia).
Key areas of the Institute: planning and design of geological exploration, assessment of reserves and resources of oil, gas and condensate, as well as processing and interpretation of seismic data.
On the basis of the institute, a corporate center for storing seismic information was created, containing seismic data for all licensed areas of the Company. The number of personnel of LLC RN-KrasnoyarskNIPIneft is over 400 people.
