Thermo‐Hydrodynamic Processes of Microparticles in Fractures: A CFD–DEM Approach
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 10, Page 4230-4246, July 2026.ABSTRACT Controlling fracture permeability plays a critical role in subsurface energy applications, particularly in geothermal energy production and enhanced carbon sequestration, where regulating fluid flow is essential. The use of microcapsules has become a promising solution to enhance fracture permeability by providing a controlled sealing ...

The price responsiveness of shale producers: Evidence from micro data
Quantitative Economics, Volume 17, Issue 2, Page 394-430, May 2026.We show that U.S. shale oil producers exhibit a high degree of short‐run price responsiveness, primarily through the timing of well completions and refracturing. Using a novel monthly well‐level panel covering over 120,000 shale wells across ten states from 2005 to 2019, we document significant supply adjustments to price signals.

Water Resources Research, Volume 62, Issue 4, April 2026.Abstract The migration‐clogging‐sealing process of microparticle suspensions in constricted channels is highly relevant to geotechnical, hydraulic, and environmental engineering. In this study, a coupled lattice Boltzmann‐discrete element method is employed, incorporating dense‐particle corrections into the classical partially saturated method and ...
