In many parts of the world, environmental sensitivity or operational restrictions make the acquisition of seismic survey using conventional active sources challenging, if not impossible. Some national and international authorities have established standards to govern the deployment of acoustic tools, and the regulators and NGOs demand that the operators demonstrate how they can reduce the impact of seismic data acquisition on the environment.
TenzorGEO’s passive seismic survey does not require the use of an active source. Onshore, it avoids the need for heavy vibroseis source trucks to be moved across fields or forests and the concomitant necessity for line clearing or compaction of valuable farmland. Offshore, TenzorGEO’s method is applied without the use of active compressed air source, meaning there is no sound propagated into the marine environment.
Onshore and offshore, TenzorGEO’s technology attributes are the absence of the active sound source and lower environmental impact. These features make it more straightforward to demonstrate to the authorities that the impact of seismic data acquisition is as low as reasonably practical (ALARP) and to obtain necessary environmental permits. In addition, this neutral approach is more likely to allay concerns from the wider stakeholder community, including NGOs and members of the public.
TenzorGeo believes that its passive seismic data acquisition technology delivers a transformational change. It offers a modern-day solution to balancing the operational needs with a wider environmental concern, by dramatically reducing the impact of conducting seismic surveys on the protected and conservation areas.
