Acquisition of 3-D seismic surveys in Oman commenced in earnest in 1987 and has been continuous until today. Improvements in data acquisition have been made over the years, be it in small steps and based on similar geometries. A study was carried out to try to further improve data quality and/or efficiency. Two alternative acquisition techniques, ‘wide-line’ and ‘slip-sweep’, were identified and have been the subject of field tests. The results indicate that efficiency of vibroseis seismic acquisition can be substantially increased without, as far as the limited tests indicate, an appreciable impact on quality.
