Application of dip and spectral maps to the Pikes Peak data

Natalia Soubotcheva

ABSTRACT

The frequency content of the seismic data may reveal some additional information to the interpreter. The unique form of the frequency analysis (S-transform) described in this paper allows us to display 2D seismic data in the form of dip and spectral maps. The S-transform has been successfully applied to the Pikes Peak seismic data to validate the position of the anomaly earlier discovered on the inverted section. The dip maps were used to trace the geological structure of the surveyed area, the spectral maps revealed a low-frequency anomaly just below the productive zone. The frequency analysis combined with conventional interpretation methods can lead to a greater understanding of data and more accuracy in reservoir prediction.
