  • CGG Launches TopSeis - The Solution for Imaging Shallow Reservoirs

    CGG announced today at ONS 2016 the launch of TopSeis™, the latest evolution in offshore broadband seismic, specifically designed to overcome the intrinsic lack of near offsets inherent in 3D towed-streamer seismic. Exacerbated by the use of progressively wider spreads to meet the industry’s quest for greater efficiency, the lack of near offsets leads to an inability to image shallow ...

  • JPT: Online Digital Rock Portal Launches

    Since the 1990s, X-ray computed tomography (CT) has become increasingly popular for its ability to yield big insights from tiny rock samples. But the volume of data produced from CT scanners is anything but tiny, and that makes sharing and storing the files a challenge. In an effort to address this issue and foster collaboration in an area where there is currently very little, researchers at the ...
