Abstract

With modern vibroseis source controllers and high-channel count recording systems, it is now possible to acquire very high source density (1000 VPs/km2 or greater) 3D surveys in an equivalent amount of time as more conventional (400 VPs/km2) surveys. Multiple vibroseis fleets are distributed over a receiver super-spread (~20 km x ~6 km) and operate in a near-simultaneous sweep mode, with or without time and distance rules. When using near-simultaneous source recording, the success of random noise attenuation algorithms depends on the distribution of the inherent crosstalk interference. This distribution is now managed at the acquisition design stage to optimize crosstalk noise attenuation methods.
