cigChannel: A massive-scale 3D seismic dataset with labeled paleochannels for advancing deep learning in seismic interpretation

Meandering channel subset of the cigChannel dataset (V1.0)

cigChannel (V1.0) is a dataset created by the Computational Interpretation Group (CIG) for the deep-learning-based paleochannel interpretation in 3D seismic volumes. Guangyu Wang,  Xinming Wu and Wen Zhang are the main contributors to the dataset.

This dataset contains 1,200 synthetic 3D seismic volumes with labels of meandering, distributary and submarine channels. Seismic impedance and sedimentary facies (submarine channel only) volumes correspond to the seismic volumes are also included in this dataset. Components of this dataset are listed below:

Due to the size limitation of the uploaded files, we have to publish the dataset in separated versions (uploads). This version includes the meandering channel subset, which contains the following zip files:

Meandering_Channel_Ip_xx-xx.zip: Seismic impedance volumes of sample No.xx to No.xx.

Meandering_Channel_Label_xx-xx.zip: Binary-class label volumes of sample No.xx to No.xx, where the value 0 represents the background (non-channel areas) and 1 represents the meandering channel.

Meandering_Channel_Seismic_xx-xx.zip: Seismic (amplitude) volumes of sample No.xx to No.xx.
