Increasing resolution and productivity of Vibroseis methods with enhanced simultaneous sweeps and cabled acquisition

The possibility of 3D seismic survey productivity multiplication will lead to seismic survey coverage of a larger area in one field season or increase the density of observations. The paper presents the results of a 3D field experiment comparing three increased productivity techniques: Slip-sweep, synchronous simultaneous pseudo-random signals (Shuffle), and independent simultaneous sweeping (ISS) with Broadsweep signal. For the first time, we perform a method for ISS continuous recording using a standard cabled system. The method will make it possible to implement high-productivity acquisition into the practice of field crews equipped with standard cabled recording systems, without additional re-equipping them with autonomous wireless recording modules. In the combination with Broadsweep sweep, ISS provides for more resolved seismic images.
