Hydrocarbon Micro-Seepage Anomalies Detection Algorithm Based on FPCS for Hyperspectral Remote Sensing Data

Article Preview

Abstract:

Long-term hydrocarbon micro-seepages develop diverse arrays of chemical and mineralogical changes in rocks and soils. We called this change mineral alteration. Mapping this mineral alteration is thus a potential tool for hydrocarbon exploration. The surface changes caused by hydrocarbon seepage can potentially be detected by remote sensing techniques. In this paper, we discussed some methods which can heighten the altered mineral on the map. The feature-oriented principal component selection (FPCS) and band ratio method collaborated together in extracting the abnormal area. SASI airborne hyperspectral data of Xifeng oilfield which located in southern Ordos Basin were used in this experiment . The experimental results show that the methods adopted in this paper have a good advantage of detecting surface anomalies and alternations associated with oil and gas information.
