Paper Number: SEG-2022-3750831
... The paper introduces an integrated machine learning-based fault classification workflow that creates fault component classification volumes that greatly reduces the burden on the human interpreter. We first compute a 3D fault probability volume from pre-conditioned seismic amplitude data using...

..., subjective and non-repeatable. Thus, we propose to train an end-to-end deep neural network (DNN) to identify the facies of the carbonate rocks from acoustic image logs and gamma ray logs. The well-trained DNN generalizes well to the test and uncertain sections. Compared with manual classification, the DNN...
