Recent advances in land seismic recording equipment have increased the options available for acquisition geophysicists. There are now four main competing types of sensors. The selection of sensor type is today a major decision in seismic survey design as it will greatly affect the channel-count requirements for 3D land seismic acquisition and the resulting data quality. Channel-count requirements for 3D land acquisition in Kuwait and the concepts involved, which are not limited to Kuwait environment, are herein presented and their impact examined. The analysis shows that in 3D land seismic data acquisition, in spite of the recent advancements, the industry is still facing a challenge to properly sample data in the spatial domain due to channel-count limitations of today's recording systems.
