Havspurv High Resolution 2D Seismic Survey

Enhancing Hydrocarbon Exploration in the Barents Sea

The Havspurv High Definition 2D Seismic Exploration spans over 10,000 kilometers, offering high-definition, high-resolution data over the Barents Sea. This seismic survey (NPD Seismic Survey SS1101) imparts the debut regional survey in the Barents Sea, prioritising major structural elements, providing accurate imaging of upper sedimentary units and underlying fault patterns.

By employing a high-frequency source signature, the Havspurv 2D Seismic Exploration enhances the recoverable high-frequency signal in the data, delivering high-resolution scans of shallow units and fault patterns. This enables a nuanced understanding of hydrocarbon distribution and fault systems. The processing of the data is engineered to sustain the high-frequency content, leveraging cutting-edge demultiple algorithms and generating a comprehensive suite of supplemental products during the PSTM sequence. The added products and the elevated sample rate of acquisition hold promise for future inversion studies.
