Play types, geologic characteristics and exploration domains of lithological reservoirs in China

Petroleum Exploration and Development, 2016
By dissecting thirty-six representative oil-gas reservoirs and analyzing accumulation conditions of giant oil and gas provinces in four prototype basins, including the Songliao Rift and Depression Basin, the Mesozoic Ordos Depression Basin, the Bohai Bay

OIL YIELD AND BULK GEOCHEMICAL PARAMETERS OF OIL SHALES FROM THE SONGLIAO AND HUADIAN BASINS, CHINA: A GRADE CLASSIFICATION APPROACH; pp. 402–418 [PDF]

Oil Shale, 2013
Oil shale evaluation is based on oil yield by low-temperature carbonization, which is an extremely complex process. The TOC, semi-coke content, gas loss, bulk density, S2 and HI correlate well with oil yield.

Lower limits and grading evaluation criteria of tight oil source rocks of southern Songliao Basin, NE China

Petroleum Exploration and Development, 2017
Taking the southern Songliao Basin as the target area, the hydrocarbon expulsion volume from source rocks has been quantitatively evaluated in this paper, based on the material balance method. Employing the “Overpressure” module of PetroMod software, the

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Machine Learning Approaches for Predicting Total Organic Carbon From Petrophysical Well Logs in the Wufeng–Longmaxi Shale, Southeast Sichuan Basin, China

Geoscience Data Journal, Volume 13, Issue 4, October 2026.
This study demonstrates the application of machine learning models—Random Forest, XGBoost, and Multiple Linear Regression—to predict Total Organic Carbon (TOC) from well logs, significantly improving TOC prediction accuracy and reliability across diverse geological settings compared to traditional log‐based methods.
