Rosneft and ExxonMobil started 2D seismic exploration at the Anisinsko-Novosibirsky and Ust-Oleneksky license blocks in the Laptev Sea Tuesday.

In 2013, Rosneft and ExxonMobil signed a cooperation agreement to explore multiple Arctic and Russian fields including Anisinsko-Novosibirsky and Ust-Oleneksky.

The exploration work will cover up to nearly four thousand linear miles in the Laptev Sea and will last until the end of October.

The Laptev Sea is located in the Arctic Ocean.

Ust-Oleneksky covers 24,750 square feet and has water depths between 62 feet and 295 feet.

Anisinsko-Novosibirsky covers 54,433 square feet and has water depths between 65 feet and 6,561 feet.

The survey will be carried out by Russia-based survey company DMNG Sakhalin Geophysical with the research vessel Academik Fersman.

The research will provide regional data on the geological structure of resources that will be used to identify oil and gas objectives for further studies.

A bathymetric survey of the seabed surface with multibeam echosounder will also be carried out to define depth and study the seabed’s topography.

Geological prospecting work in the Laptev Sea is being carried out ahead of license commitments subject to all requirements of environmental protection legislation of the Russian Federation.

The survey works is being handled by Rosneft’s subsidiary RN-Shelf-Far East.
