| Abstract: | Among the surface sediments anomalies caused by hydrocarbon leakage ofheavy oil reservoir, bleaching of red beds,
enrichment of ferrous-iron and alterations of clay minerals and carbonates exhibit diagnostic spectral features. For heavy oil
exploration in thewestern slope of Songliao Basin, ETM+7image is used to identify anomaly caused by hydrocarbon leakage.
PrincipalComponentAnalysis (PCA), band ratio, and FalseColorComposition (FCC) are used in image process. Fourprincipal
components (PCs) including1,3,4,5-PC3(the third componentof thePCA on band1,3,4and5),1,3,5,7-PC3,2,3,5,7-PC3
and3,4,5,7-PC4show steady spectralenhancementfor thehydrocarbon-inducedminerals. ThePCs are combinedwithband ratiosof
3/1,4/3and7/5forFCC.
FourFCC images are selected for hydrocarbon-induced area delineation. Result indicates that the identified anomalous area is
related to the geological setting and consistentwith the strata sections inmostarea. |
