Gulspurv 3D High Resolution Seismic Survey (NPD Seismic Survey SSG1201) comprises of 1,997 km2 of acquired 3D data over the highly prospective Bjørnøyarenna Fault complex. The processed data from the survey shows excellent resolution with good shallow structures.
The key objective of the survey was to properly image the structure and stratigraphy within the shallow section to produce high resolution data to better understand the nature and geometry of the faulting and distribution of potential reservoirs in which leads to more confident definition of potential hydrocarbon traps.
Excellent data quality has been achieved in the prospective shallow intervals while maintaining interpretability of the older structural framework required for understanding of this complex area. Maximum shallow fold was achieved with a focused source effort of a smaller volume (1,310 cu) high frequency source signature and shot point interval of 12.5m (flip-flop) to better preserve the shallow structural content in the data.
The data processing is tailored to maintain the high frequency content with the latest demultiple algorithms being employed and using modern interpolation and transforms.
