f Dual source vibroseis acquisition for 2D survey by using conventional and E-code sweeps

AGIP has successfully transferred in the 2D acquisition the Dual source Vibroseis technique to achieve high resolution, low cost, vibroseis 2D data, following the fruitful experiences carried out in 3D acquisition (L. Bertelli, R. Servodio, 1991 and L. De Luchi, R. Marshall, H. Werner, 1987). As well known the aim of the dual source technique is to improve field efficiency by increasing the production and reducing the survey duration and costs. As a matter of fact the application of the dual source methodology in our 2D survey allowed a cost saving of about 40% of the final acquisition costs without smearing final data quality.
