Abstract
A probabilistic method for classifying observed CSEM response for a resistive anomaly to classify the response into multiple geologic categories indicative of hydrocarbon production potential. Each category is assigned a prior probability (). For each category, conditional joint probability distributions for observed CSEM data in the anomaly region are constructed () from rock property probability distributions () and a quantitative relationship between rock/fluid properties and the CSEM data (). Then, the joint probability distributions and prior probabilities for each category () are combined with observed data () and used in Bayes' Rule () to update the prior category probabilities (). Seismic data may be used to supplement CSEM data in the method.
