Low-Frequency Hydrocarbon Indication in Reflection Seismic Data
|

|

|
The Low Frequency Project is a consortium managed by the University of Stavanger in collaboration with other universities and industry in order to improve our knowledge from the mathematical, physical, numerical, and applied points of view on how the low frequency content of industry 3D seismic reflection data can be used as a hydrocarbon indicator for exploration and production purposes. |

Example of frequency analysis in the southern North Sea. The well tested hydrocarbon in the uppermost part of the Late Cretaceous Formation with more than 40% of water after acidization. The pay zone shows amplitude anomalies on the 12, 15.5, and 20 Hz spectral sections. The amplitude anomaly for pay zone faded out on the 30 and 40 Hz spectral sections, and the amplitude anomaly appears below the pay zone on the 40 Hz section. |
