The name THOR Geophysical has long been well known for its extensive experience in all varieties of 2D and 3D seismic surveys. In the fields of shallow water and transition zone acquisition, its personnel have many years of experience with leading international companies. THOR Geophysical uses telemetry systems, such as the marine version of ARAM24, for cost effective and practical data acquisition. These techniques allow the use of small vessels for the layout and retrieval of telemetry cables and remote units. A complete range of seismic sources is offered, including airgun arrays, boomers and flushed holes for specialised dynamite charges. THOR Geophysical is able to mobilise two separate crews simultaneously, one for marine and one for land/transition zone acquisition. This benefits the client by decreasing project turnaround time, thus reducing costs
