Latest field trial confirms potential of new seismic method based on continuous source and receiver wavefields

eSeismic is a novel seismic methodology based on the emission and recording of continuous source and receiver wavefields. One of the motivations behind developing the methodology has been the increased focus on the potential environmental impact of marine seismic acquisition, which the new methodology seeks to reduce. A particular focus has been placed on the peak sound pressure levels emitted from seismic sources and their potential impact on marine mammals and fish with swim bladders. Consequently, authorities across the world have started to introduce stronger regulations concerning the use of seismic sources. The industry has responded by engaging in the development of marine vibrator systems that emit lower-amplitude transient signals and hence are expected to comply with stricter environmental regulations. Different marine vibrator systems are currently being developed or tested but none have reached full-scale commercial readiness.
