Paper presented at the SEG/AAPG/SEPM First International Meeting for Applied Geoscience & Energy, September 26–October 1, 2021
Paper Number: SEG-2021-3583288
.... Experiments on gravity data show that the proposed inversion method has good robustness and generalization. In addition, the deep-learning-based inversion by using the magnitude magnetic data ( T a ) can greatly eliminate the influence of magnetization direction. Note: This paper was accepted...
