High-density low-frequency survey in the northern YNAO

The project involved a large volume of work on a territory of 450 km² . Over 180,000 physical seismic survey observations were completed in one field season.

During the work, it was possible to ensure a colossal active arrangement of 27,840 channels to obtain the most clear and detailed data with minimal distortion.

The highest survey density with more than 11,000,000 seismic traces per square kilometer. The necessity of using low-frequency recording equipment when using broadband SWIP signals for better signal penetration into the depth and for isolating important geological features has been substantiated and confirmed in practice.

Using data filtration and processing methods to suppress noise and isolate the useful signal, which is especially relevant in conditions of increased noise load.

The high recording rate amounted to an average of 1,360 physical observations daily, taking into account climatic downtime. Noise suppression and filtration methods, and environmentally friendly technologies were used.

The field season was abnormally warm, and the winter was short, nevertheless, the work was completed 10 days ahead of schedule.

The project was implemented in strict compliance with labor protection requirements and environmental standards in the difficult natural conditions of the Yamalo-Nenets Autonomous Okrug.
