On top of the spread

In order to solve the challenges of imaging the shallow reservoirs of the Barents Sea, CGG, in collaboration with Lundin Norway, have developed an innovative source-over-spread acquisition solution, known as TopSeis. This addresses the lack of near-offset data recorded in conventional towed-streamer acquisition by enabling recording of short and zero-offset data with a split spread, significantly increasing the illumination density of the subsurface. This article looks at the development of this technique with some recent results, including AVO.
