Quantitative Prediction of Coalbed Gas Content Based on Seismic Multiple-Attribute Analyses [PDF]

, 2015
Accurate prediction of gas planar distribution is crucial to selection and development of new CBM exploration areas. Based on seismic attributes, well logging and testing data we found that seismic absorption attenuation, after eliminating the effects of
