Pore Structure Characteristics and Affecting Factors of Shale in the First Member of the Qingshankou Formation in the Gulong Sag, Songliao Basin. [PDF]

ACS Omega, 2022
A major historical breakthrough has been made in the exploration of the GK (the first member of the Qingshankou Formation (K2qn1), Gulong Sag) shale oil of the Songliao Basin. However, few reports have been reported on the pore structure characteristics of this large-scale lacustrine medium-high maturity shale.

Lithofacies identification of shale formation based on mineral content regression using LightGBM algorithm: A case study in the Luzhou block, South Sichuan Basin, China

Energy Science &Engineering, Volume 11, Issue 11, Page 4256-4272, November 2023., 2023
This study is based on logging data and core testing data, and uses machine‐learning algorithms to construct a regression model for the relative content of shale minerals. The regression prediction model and mineral ternary diagrams are used to classify and identify lithofacies.

Evolution of Fractal Pore Structure in Sedimentary Rocks

Earth and Space Science, Volume 9, Issue 6, June 2022., 2022
Abstract Geological processes alter pore spaces over time, and their analysis can shed light on the dynamic fractal structure and fluid flow of rocks over time. This study presents experimental evidence to illustrate that the pore fractal structure evolves with sedimentation, carbonate cementation, clay growth, and dissolution.
