  • 3D inversion results from towed streamer EM data in a complex geological setting

    Johan Mattsson, Joel Skogman, Anwar Bhuiyan, Allan Mckay and Chris Anderson

    A newly developed, towed streamer electromagnetics (EM) system was used to acquire data over Mariner oil field in the UK North Sea during 2012. Electric field data were acquired with a single vessel, using a horizontal bipole source and sensors housed in a towed streamer. The data were acquired in a densely sampled grid, to cover a 3D subsurface volume containing the oil reservoirs. The target oil field was selected to test the ability of the EM method to detect oil reservoirs in a more complex geological setting than had previously been attempted. Complexity, in this case, means the proximity of a multi-layered resistive oil-charged reservoir to a resistive chalk “basement.”
