CGG Wraps Up Barents Sea Survey with Its New Acquisition Solution

CGG has completed acquisition of the first-ever full-scale commercial survey using TopSeis, its latest offshore broadband seismic acquisition and imaging solution.

The inaugural TopSeis survey was commissioned by Lundin Norway over the Loppa High in the Barents Sea.

TopSeis has been designed to image a carbonate reservoirs located at depths between 400m to 2000 m below the seabed. It deploys seismic sources directly above the streamers in a “split-spread” acquisition geometry.

Halvor Jahre, exploration manager, Lundin Norway, said: “Developing TopSeis has been a win-win for Lundin and CGG. It has resulted in an imaging solution for Lundin that addresses the specific challenges on the Loppa High, and has also resulted in a new promising technology for the industry. One unexpected benefit we have already seen is that the TopSeis water bottom resolution is unprecedented for seismic acquisition and is comparable with existing multibeam sonar data.”

Jean-Georges Malcor, CEO, CGG, said: “TopSeis is the result of several years of close collaboration with Lundin Norway to develop, test and industrialize this revolutionary new concept. We look forward to the results of this first full-scale survey to solve the imaging challenges and deliver new insights into the reservoirs of the Loppa High.”
