December, 2017. Vesti Gazovoy Nauki V. 4 (32). «Modern approach and promising technologies within the projects for development of oil-and-gas fields at Russian continental shelf»

It’s known that in comparison to common marine conditions the oil-gas industry of Russia has limited practical experience in prospecting and development of hydrocarbon reserves in Arctic and Far Eastern seas. Besides lack of industrial practice the marine projects related to the freezing seas meet with the unique complicated problems. Presence of sea ice and permafrost in the coastal zones seriously affects design and selection of concepts and operations for development of hydrocarbon fields.

To provide safe and profitable operation of the facilities within the ice sea environment, geothechnical conditions of the sea bottom and geocryological coastal conditions, one should precisely understand mechanics of ice, water-saturated soils and permafrost, as well as mechanisms of their interaction with different types of hydraulic structures. So, previous experience in design and operation of the marine shelf facilities in Alaska and Canada and advance scientific research of the Sakhalin offshore conditions in 1980s became a foundation for development of the adequate ice criteria for designing Sakhalin-1 and Sakhalin-2 sea platforms and their successful application up to now.

Invasion of the Gazprom PJSC to relatively deep waters of the Okhotsk Sea and Arctic stipulating for usage of the submarine production systems in new, unstudied ice environment complicates calculation of reliability and prognostication of safe operation in respect to the field industrial facilities. Usually, such tasks require implementation of long-term environmental data collection programs and probabilistic analysis of these data in order to embrace all the essential parameters of field industrial construction and operation in a particular region including account of their uncertainty.

Unfortunately, domestic fuel companies are poorly interested in the longstanding scientific works, and before sanctions preferred purchasing of proved foreign technologies. It should be mentioned that in Russia a share of R&D expenditures at enterprises constitutes 6%, whereas it runs up to 70–75% in Japan and the USA, and to 25–65% in Europe.

The presented collected papers of specialists from the Gazprom VNIIGAZ LLC and other institutes specializing in Arctic marine engineering reveal different studies related to mastering of the offshore oil and gas fields. Some of these institutions could generate innovations, but they have to adapt themselves to market requirements, which are expressed in the orders of commercial customers.
