The Lithology Cube and Attenuation Cube for Gas Detection

F-13 THE LITHOLOGY CUBE AND ATTENUATION CUBE FOR GAS DETECTION Summary 1 Gas detection is performed by combined use of the Lithology Cube and attenuation estimation. The Lithology Cube contains lithology and fluid prediction based on seismic data. The method utilises inversion of AVO attribute seismic data to physical properties. The well log data are used as learning data for prediction of rock properties from the AVO inversion results. As the seismic data have been taken to physical properties by the AVO inversion it is simple to use general rock physics knowledge in the rock property prediction. The Attenuation Cube
