eSeismic – reducing environmental noise

eSeismic developed by PGS is one of 9 candidates for this year's Exploration Innovation Prize that will be awarded at NCS Exploration in May

eSeismic was developed by PGS in cooperation with Equinor and the Norwegian Research Council.

The technology has now been selected as one of nine candidates for the Exploration Innovation Prize that will be awarded at this year’s NCS Exploration conference: Recent Advances in Exploration Tehcnology

The method reinvents seismic acquisition and processing, producing an ongoing lower-level ripple of sound, rather than the traditional series of large distinctive impulsive pops.

A recent field trial confirmed the benefits of recording continuous source and receiver wavefields, including reduced environmental impact, improved efficiency and better data quality.


5 key benefits using eSeismic

  • Environmental: Peak sound pressure levels (SPL) are significantly reduced by distributing the emitted signals in time
  • Environmental: Sound exposure levels (SEL) integrated over time can also be reduced
  • Efficiency: There are no speed limitations since the method does not require the seismic recording or the sources to be triggered with specific spatial intervals, and no listening time is needed
  • Efficiency: Rapid coverage of the target during acquisition by operating several sources simultaneously, and increasing the spread width of the sources
  • Excellence: Continuous wavefields deliver uplifts in data quality and spatial sampling of source positions

Register for the conference

The 2019 NCS Exploration Conference is held at Cambro-Silurian shales and carbonates that belong to the world famous “Oslofeltet” that have many similarities with the North Sea. On the first day of the conference, Morten Bergan will guide participants through 120 million years of Earth history.
