Current state and future directions for deep learning based automatic seismic fault interpretation: A systematic review
Abstract
Automated seismic fault interpretation has been an active area of research. Since 2018, Deep learning (DL) based seismic fault interpretation methods have emerged and shown promising results. However, to date, these methods have not been reasonably summarised, making it difficult for those involved to make sense of the current development process. To close this gap, we systematically reviewed the DL-based fault interpretation literature published between 2012 and 2022, and searched seven digital libraries. Fault interpretation has been considered an image-processing task using only convolutional neural networks(CNN)-based DL methods, and most of them have been trained in a supervised manner. U-Net and its variants designed for the image segmentation task are the most commonly used network structures. A total of 73 seismic datasets were summarised from the 56 articles included, of which only three field datasets and four synthetic datasets were publicly available benchmarks. The study reported benefits of using DL, such as its outstanding learning and generalisation capabilities or predicting faults in a fast, cheap and repeatable manner, which ultimately led to an increase in the acceptability of these methods and the potential to incorporate them into oil and industry workflows. However, we identified 12 challenges that hinder its integration into industrial workflows, including the most discussed lack of sufficient annotated data. We conclude with an in-depth discussion of…
