Evolution of Fractal Pore Structure in Sedimentary Rocks

Earth and Space Science, 2022
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 ...

Causes and Controlling Factors of Overpressure Systems in the Qingshankou Formation: Insights for Unconventional Oil and Gas Exploration

Processes
Overpressure systems in the Qingshankou Formation of the Gulong Sag have a significant impact on unconventional shale oil accumulation, but their distribution and genesis are unknown. This study uses a comparative analysis of three primary pressure prediction methods—the equivalent depth method, the Eaton method, and the Bowers method—to investigate ...
