Strata division with well logging utilizes the abrupt changing points or regions of signals. while the changing law of the wavelet modulus maxima under different scales can exactly describe the position and modality of the changing points. Based on the idea of reconstruction of wavelet modulus maxima. the well logging data fusion method built on the multiscale edge detection principle... https://www.spidertattooz.com/OPI-GelColor-The-Color-That-Keeps-On-Giving-0-5-oz-HPJ07-p22791/
