F
ormany years, the seismic industry has strived to reduce its impact on the
environment.
In land acquisition, themain concern is generally vehicle traffic. Be it the source
vehicle fleet roaming thousands of kilometres in sometimes fragile soil and ecosystems, or
the vehicles required for the transport and supply of field staff.
Inmarine seismic, aftermore than four decades of worldwide acquisition, there is still
no consensus in the scientific community on the potential impact of anthropogenic sound
generated during geophysical surveys onmarinemammals. This topic has lately received
increased attention fromthe government regulators of several countries, leading to the
introduction of mitigation andmonitoring guidelines aimed at reducing the potential
impact of marine seismic sources onmarinemammals.
ENVIRONMENTALLY
EXPLORATION
Nicolas Tellier and Laurent Guérineau, Sercel, France,
examine new equipment that has been designed to
reduce the environmental footprint of both land
and marine seismic acquisition.
