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 ...

Study on proppant migration and placement under sand-carrying action of clean fracturing fluid

Meikuang Anquan, 2022
In order to explore the law of proppant migration and placement under clean fracturing fluid, an Euler multiphase flow model was established through FLUENT numerical simulation software based on computational fluid dynamics(CFD).

Proppant Fracture Conductivity With High Proppant Loading and High Closure Stress [PDF]

SPE Hydraulic Fracturing Technology Conference, 2012
Abstract Ultra-deepwater reservoirs are important unconventional reservoirs that have the potential to produce billions of barrels of hydrocarbons, and are usually high pressure and high temperature with relatively high permeability. One major challenge of an unconventional, ultra-deepwater reservoir is pumping an effective and robust ...

Effect of proppant pumping schedule on the proppant placement for supercritical CO2 fracturing

Petroleum Science, 2022
Abstract Supercritical CO2 fracturing is a potential waterless fracturing technique which shows great merits in eliminating reservoir damage, improving shale gas recovery and storing CO2 underground. Deep insight into the proppant-transport behavior of CO2 is required to better apply this technique in the engineering field.

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.

Mechanisms of Suspended Microparticle Clogging in Constricted Channels: Insights From a Lattice Boltzmann‐Discrete Element Simulation

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 ...

Numerical simulation study on the ultimate injection concentration and injection strategy of a proppant in hydraulic fracturing

Frontiers in Energy Research
The injection volume and the distribution of a proppant inside a fracture have a direct impact on the stimulation effect of fracturing. In this study, a new proppant transport model was established based on the Euler method.
