Investigation on Proppant Placement in Hydraulic Fractures Based on CFD-DEM

Shiyou jixie, 2023
In order to optimize the transport performance of proppant in shale gas reservoirs, the computational fluid dynamics-discrete element method(CFD-DEM)was used to numerically simulate medium-sized rectangular fractures, with gravity, buoyancy, and particle-

Experimental and Numerical Study on Proppant Transport in a Complex Fracture System

Energies, 2020
Slickwater fracturing can create complex fracture networks in shale. A uniform proppant distribution in the network is preferred. However, proppant transport mechanism in the fracture network is still uncertain, which restricts the optimization of sand ...

Study on proppant settlement and migration in a single microfracture [PDF]

E3S Web of Conferences, 2023
Micro-fractures are widely developed in deep shale gas reservoirs after fracturing. Effective support of micro-fractures is of great significance to slow down the production decline rate of shale gas Wells. When the particles enter the fracture, they can

Calibration of the Interaction Parameters between the Proppant and Fracture Wall and the Effects of These Parameters on Proppant Distribution

Energies, 2020
Saltation and reputation (creep) dominate proppant transport rather than suspension during slickwater fracturing, due to the low sand-carrying capacity of the slickwater. Thus, the interaction parameters between proppants and fracture walls, which affect

Investigating the Impacts of Nonuniform Proppant Distribution and Fracture Closure on Well Performance in Shale Gas Reservoirs

Frontiers in Earth Science, 2022
The nonuniform distribution of proppant in hydraulic fractures is an essential factor determining the accuracy of well performance evaluation in shale gas reservoirs. In particular, unpropped and propped parts hold distinct closure behavior. To study the

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).

An experimental study of proppant transport mechanisms to the pump intake in low-flow oil wells

Petroleum Research
The exploitation of low-flow oil wells following hydraulic fracturing is often hindered by residual proppant and proppant production during early production phases, which can infiltrate pumps and drastically shorten their service life.
