Barents Data Proves Penta Source Effectiveness

Data is now available from an efficient and highly advanced project in the Barents Sea, that combined an ultra-wide-tow penta source with a dense GeoStreamer spread and long tails. The results show exceptional imaging of the near surface.

To examine the near-offset coverage, spatial sampling density, and broadband data-quality achievable with wide-tow multi-sources for shallow imaging, PGS employed a dense GeoStreamer spread and five sources with a total separation of 315 m.

The 3D volume just released proves the effectiveness of this acquisition setup, delivering high-resolution imaging of shallow targets and hazards, as well as excellent images of deeper geological structures and exploration targets.

Demonstrated Benefits

  • High-resolution imaging of shallow targets and geohazards
  • Uniform ultra-near-offset coverage
  • Robust AVO for shallow targets
  • Improved pre-processing, especially multiple removal (SRME)
  • Dense spatial-sampling and high trace-density
  • Uncompromised acquisition efficiency

“This dataset demonstrates the imaging clarity of shallow geological targets that can be achieved with wide-towed multisource and tailored streamer spreads. Once again, PGS has delivered excellent data quality efficiently, using an advanced acquisition setup," says Gunhild Myhr VP Business Development Eurasia.

The acquisition setup enabled dense spatial-sampling with a 6.25m x 6.25m bin size, high trace-density, and uniform coverage of the ultra-near offsets without the typical near-offset gaps at sail-line boundaries. Depth slices 410 m and 468 m

The data was acquired on the Loppa High in 2020 as an extension of MultiClient survey PGS 20001 NBS. The full results from this survey will be available this summer.
