Spectral Decomposition Provides Rapid Screening Tool for Gas Potential in the Norwegian Sea

A-33 SPECTRAL DECOMPOSITION PROVIDES RAPID SCREENING TOOL FOR GAS POTENTIAL IN THE NORWEGIAN SEA 1 R.H. LEADHOLM T.J. AUSTIN and P.F. OSTENDORF ConocoPhillips Norge PO Box 220 N-4098 Tananger Norway EAGE 65th Conference & Exhibition — Stavanger Norway 2 - 5 June 2003 Summary Investigation of 3D data sets over two deep water gas accumulations several dry tests and various undrilled prospects in the Vøring Basin of the Norwegian Sea shows that spectral decomposition phase and amplitude spectra can be used to define gas accumulations. This technique provides a rapid screening methodology and compliments the more traditional utilization of spectral
