CGG has over 30 years’ experience of marine acquisition in the Arctic. To explore this area responsibly requires specialized equipment and methods, deployed by exceptional crews who work closely with local agencies to meet the environmental challenges.
We provide the full suite of geoscience services, from survey evaluation and design, through acquisition and processing, to reservoir characterization to make your Arctic survey successful. Our Robertson group have integrated all the available data for most of the Arctic continental shelf to provide geological studies to help you design the best survey to meet your needs.
We have the specialized experience and the resources to overcome the challenges of remote location, extreme cold and environmental sensitivity required to acquire marine seismic data in these areas:
Successful Arctic exploration requires detailed pre-survey planning for HSE (Health, Safety and the Environment) preparedness, contingency planning and environmental and cultural sensitivity.
It is important to satisfy the local communities that their interests will be protected, as some still depend, at least in part, on the local wildlife for subsistence. To do this we employ local Marine Mammal Observers (MMO's) to monitor the safety radius and record wildlife.
Source 'soft-start' techniques are used to warn marine mammals and polar bears of pending seismic activity and to allow sufficient time for those animals to leave the vicinity.
Ice forecasts, supported by satellite imagery, reconnaissance flights and scouting trips by the chase boats, allow careful monitoring of the ice.
Operational flexibility allows 2D data to be recorded while waiting for sufficient open water to deploy multiple streamers for a 3D survey.
There were only 42 minutes of technical downtime during an entire 55-day Beaufort Sea campaign, allowing more data to be acquired than anyone had anticipated.
These areas are often remote, so fuel and food supplies have to be carefully planned. In case of emergencies, a Search and Recovery (SAR) helicopter has to be available at all times.
Safety is always of prime importance. Standard training procedures and strict environmental procedures are enforced on all vessels.
Additional measures are required in the Arctic:
