Quantitative Characterization for the Micronanopore Structures of Terrestrial Shales with Different Lithofacies Types: A Case Study of the Jurassic Lianggaoshan Formation in the Southeastern Sichuan Basin of the Yangtze Region

Geofluids, Volume 2021, Issue 1, 2021., 2021
Due to the specificity of the geological background, terrestrial strata are widely distributed in the major hydrocarbon‐bearing basins in China. In addition, terrestrial shales are generally featured with high thickness, multiple layers, high TOC content, ideal organic matter types, and moderate thermal evolution, laying a solid material foundation for

The Use of 3D Convolutional Autoencoder in Fault and Fracture Network Characterization

Geofluids, Volume 2021, Issue 1, 2021., 2021
Conventional pattern recognition methods directly use 1D poststack data or 2D prestack data for the statistical pattern recognition of fault and fracture network, thereby ignoring the spatial structure information in 3D seismic data. As a result, the generated fault and fracture network is not distinguishable and has poor continuity.

Reservoir and development characteristics of the Da'anzhai tight oil in Sichuan Basin, SW China

Petroleum Research, 2019
The oil in the Jurassic Da'anzhai reservoirs in the Sichuan Basin is unconventional tight oil, which accumulated in or near source rocks, and did not experience extensive migration in a large-scale long distance. The first submember, second submember and
