Influence of Geological Factors on Asphaltene Precipitation From Crude Oils in Tuoputai Area, Tarim Basin, Northwestern China

Journal of GeoEnergy, Volume 2026, Issue 1, 2026.
Asphaltene precipitation frequently occurs in oil wells within the Tuoputai area of the Tarim Basin, significantly hindering production efficiency. In addition to external factors, such as temperature and pressure, the effects of geological factors on asphaltene precipitation warrant further investigation.

Thermodynamically Consistent Modeling of Coupled Elastoplastic Geomechanics and Two‐Phase Flow With Capillary Hysteresis in Porous Media

International Journal for Numerical Methods in Engineering, Volume 126, Issue 24, 30 December 2025.
ABSTRACT We propose a unified constitutive framework for two irreversible processes governing coupled flow and geomechanics in porous media: capillary hysteresis in two‐phase flow and elastoplastic deformation. Extending our previous work that draws an analogy between capillary hysteresis and elastoplasticity theory, we introduce an additive ...

Review of artificial intelligence applications in geothermal energy extraction from hot dry rock

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 651-672, December 2025.
This paper systematically summarized the applications of artificial intelligence (AI) in hot dry rock (HDR) geothermal exploitation and discussed the limitations and opportunities. A novel intelligent HDR exploitation system was proposed to promote the development of HDR toward more efficiency, economy, and intelligence.

Multiphysics modeling of coupling compressed‐air energy storage‐thermal storage in salt caverns: An approach to insoluble sediment as heat reservoir feasibility analysis

Deep Underground Science and Engineering, Volume 4, Issue 4, Page 777-791, December 2025.
This study investigates the feasibility of utilizing insoluble sediments in salt caverns for short‐ and long‐term thermal energy storage applications. The analysis revealed three key thermal characteristics of these sediments: (1) thermal shock resistance, (2) temperature differential compensation capability during air injection, and (3) high ...
