  • What's new in exploration


    Perry A. Fischer, Editor

    New Valhall seismic source? A viable seafloor seismic source has been proposed for at least the past 15 years. Several experiments have been conducted during that time, all of which proved the concept. Problems occur with hardgrounds, a rugose seafloor, deepwater depths and the associated problems with positioning and energy transfer to the source, and the time and cost of the procedure. The benefits include superior energy transfer to the subsurface, elimination of multiples and ghosts caused by reverberations between the seafloor and sea surface, and the generation of strong shear waves – even polarized shear waves.
