| Abstract: | This work represents the results of study of the following problems by image processing techniques: the quick extraction of weak magnetic anomalies with high frequency, the evaluation of depth for highfrequence magnetic anomalies,the normalization of radiometric anomalies,the analysis of typical anomalous profiles and the prediction of perspective anomalies to find oil and gas.Four new perspective anomalies for oil gas were discovered. The study had been finished at the beginning of 1990. Comparing with the results of exploration in 1991, we have been encouraged by the fact that not only on 3 out of the 4 anomalieas the oil and gas were found, but also on one of them the gas was found. |
