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 ...

The strata and palaeo-geomorphology framework at the end of neoproterozoic and development mode of source rocks at the beginning of Cambrian in Tarim Basin, China

Journal of Natural Gas Geoscience, 2017
Referred to the new recognition from petroleum exploration of the Sinian to Cambrian in South China, it could be considered that the distribution of the early Cambrian source rocks was controlled by the palaeo-geomorphology at the end of Neoproterozoic ...

Magnetic field and rotor impedance analysis of solid rotor induction motors using the multilayer analytical method

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
A multi‐layer analytical model for calculating the magnetic field and equivalent circuit parameters of solid rotor induction motors is proposed, which can consider the effects of saturation effect and end effect of the solid rotor. The accuracy of the analytical model is verified by finite element simulation and prototype test.

Towards an improved understanding of Ca–Mg carbonates with nonplanar surfaces: An experimental approach

Sedimentology, Volume 72, Issue 1, Page 100-131, January 2025.
ABSTRACT Saddle dolomite is a Ca–Mg carbonate characterized by curved crystal faces, curved cleavage and sweeping extinction under cross‐polarized light. Saddle dolomite and, generally, Ca–Mg carbonates with curved crystal faces, are often assigned to the burial (hydrothermal) realm and serve as proxy archives for hydrogeochemical processes in ...
