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

description: Assorted 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.

cigChannel (V1.0) contains 1,600 synthetic 3D seismic volumes with labels of meandering channels, tributary channel networks and submarine canyons. Seismic impedance and sedimentary facies (only for submarine canyons) 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. This version includes the assorted channel subset, which contains the following zip files:




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

Assorted_Channel_Label_xx-xx.zip: Multi-class label volumes of sample No.xx to No.xx, where the value 0 represents the background (non-channel areas), 101 represents meandering channel No.1, 102 represents meandering channel No.2, etc., 201 represents distributary channel network No.1, 202 represents distributary channel network No.2, etc., and 301 represents the submarine channel (only one submarine channel per volume).

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


Samples in this subset feature different geologic structures:



Sample No. 0 to No. 49 feature horizontal structure. 

Sample No. 50 to No. 99 feature inclined structure.

Sample No. 100 to No. 299 feature folded structure. 

Sample No. 300 to No. 399 feature folded and faulted structures (uploaded as an expansion package).
