Rosneft conducts prospecting operations in Laptev Sea

Russia's state-owned oil giant Rosneft and experts from the Arctic Research Center have conducted regional engineering and geological prospecting operations at the company's licensed oilfields in the Laptev Sea. Experts sailing aboard the Professor Molchanov research vessel studied the Anisinsko-Novosibirsky, Ust-Lensky and Ust-Oleneksky licensed hydrocarbon deposits using low-depth geophysical methods.

Scientists sank automatic buoys and collected data about annual changes in the morphometric and dynamic specifications of sea-ice formations, sea-level fluctuations, waves and currents in licensed sectors of the Arctic continental shelf. Members of the expedition also conducted meteorological and sea-ice observations, as well as biological research, including efforts to monitor marine-mammal and bird populations.

Geophysicists managed to obtain unique data about the seabed's cross-section and structure, making it possible to assess the specifics of sedimentation layers, the properties of frozen layers and natural gas emissions.

Expedition members also tried out new experimental seismic-acoustic methods for collecting additional data about the structure of sedimentary layers.

All expedition projects were implemented with due consideration for the rigid environmental and industrial safety standards.
