Multidimensional Characterization of Formation Damage Mechanisms in Ancient Carbonate Reservoirs: Synergistic Effects of Inorganic‐Organic Interactions

Energy Science &Engineering, Volume 13, Issue 6, Page 2663-2671, June 2025.
ABSTRACT Formation clogging in carbonate gas reservoirs is a significant challenge in natural gas extraction, particularly due to the complex mineral composition and physicochemical characteristics of carbonate rocks, which make clogging phenomena even more complex. This study aims to delve into the formation mechanisms of formation plugs in carbonate

New Pattern of Uplift‐Depression of the Pre‐Cambrian Basement in the Sichuan Basin: Constraints From Multi‐Seismic Parameter Imaging

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The structural configuration of the pre‐Cambrian basement in the Sichuan Basin, a highly promising region for hydrocarbon exploration, has been a subject of long‐standing debate. Here, we determined the fine‐scale three‐dimensional seismic models of the Sichuan Basin using 187,356 high‐quality P‐ and S‐wave travel time pairs recorded by 627 ...

Bimodal In Situ Analyzer for Circular RNA in Extracellular Vesicles Combined with Machine Learning for Accurate Gastric Cancer Detection

Advanced Science, Volume 12, Issue 15, April 17, 2025.
They developed a bimodal EV‐circRNA in situ analyzer (BEISA) using a DNA rectangular frame‐guided hybridization chain reaction (RF‐HCR) system. By combining ML algorithms and bimodal EV‐circRNA in situ analysis, this platform provides a promising tool for the analysis of gastric cancer‐derived EV‐circRNA, making diagnosis and staging of gastric cancer ...
