A Deep Learning Seismic Processing Framework Based on Pre-Training: Giving the Dataset the Attention It Needs
Bibliographic record
Abstract
Summary Every seismic dataset has its particular characteristics guided mainly by the property of the subsurface it covers, the data acquisition parameters (the survey), and by the often unique noise condition for every dataset. Capturing such characteristics in a neural network model for efficient application of processing tasks offers a more effective approach to incorporating machine learning than training neural networks for specific tasks that may or may not transfer well to new data. We use a framework for seismic processing that allows us to pretrain a neural network to learn the features of a seismic dataset, and then fine tune the network for any downstream processing task. We take advantage of the fact that most processing tasks utilize the same features embedded in the seismic dataset, and thus, these features can be stored in a common pre-trained network in a self-supervised manner, we refer to as StorSeismic. We provide insights into the framework as it captures the seismic dataset features. Then, we use the labeled synthetic data to fine tune the pre-trained network in a supervised fashion to perform various seismic processing tasks, like denoising, low frequency extrapolation, first arrival picking, and velocity estimation, with satisfactory results.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
