In early April, Rosneft and ExxonMobil began aerial gravity-magnetic surveys over offshore blocks in the Yuzhno-Chukotsky licence area in the eastern Russian Arctic to establish the subsurface structure of the field.

As part of a framework agreement, the companies will explore six license areas jointly in the Chukchi and the Laptev Seas: Ust-Lensky, Ust-Oleneksky, Anisinsko-Novosibirsky, Yuzhno-Chukotsky, and Severo-Vrangelevsky 1 and 2 areas, for which Rosneft received exploration licenses in 2013.

By the end of 2014, all six licence areas, with a total area of 440,000sq m will be surveyed by three airplanes carrying magnetometric and gravimetric equipment.

RN-Shelf Far East CJSC (joint stock company), a Rosneft subsidiary, will conduct the aerial gravity-magnetic survey, which studies the subsurface structures of oil and gas basins and precedes seismic exploration.

The airborne equipment records the intensity and direction of geomagnetic and gravity fields related to subsurface rocks in the area in question.

The surveys can be performed through ice without the need for survey vessels, says Rosneft, and it estimates the recoverable reserves from the license areas at 7233mt of oil and 6709bcm of gas.

Vlada Rusakova, Vice President of Rosneft; Lev Brodsky, General Director of RN-Shelf-Far East CJSC; and Jim K. Flood, Vice President - Arctic and Eastern Canada, ExxonMobil Development Co., will all speak at the 18th annual Sakhalin Oil & Gas Conference, 22 - 25 September 2014, Yuzhno-Sakhalinsk, Russia. The conference theme is "Sakhalin and the Russian Far East — Advancing Russia’s Eastern Energy Vector.
