Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant

Journal of Basic & Applied Sciences
Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback.

Simulation and solution of a proppant migration and sedimentation model for hydraulically fractured inhomogeneously wide fractures

Energy Exploration & Exploitation
The distribution of proppant during hydraulic fracturing may directly contribute to the flow conductivity of the proppant fracture, so research on the migration and sedimentation of proppant in the fracture and the final distribution pattern is of great ...

Numerical Simulation of the Proppant Concentration in the Annulus near Packer

Shiyou jixie, 2018
To study the variation of the proppant volume fraction in the annulus near packer, using the Euler-Eulerian double-fluid two-phase flow model and considering the coupling between the fluid-solid and the solid-solid, numerical simulation study was carried

Efficient placement technology of proppants based on structural stabilizers

Petroleum Exploration and Development
Fiber is highly escapable in conventional slickwater, making it difficult to form fiber-proppant agglomerate with proppant and exhibit limited effectiveness. To solve these problems, a novel structure stabilizer (SS) is developed.

The influence of fracturing fluid temperature and viscosity on the migration and distribution of proppants within a fracture

Journal of Petroleum Exploration and Production Technology
This work presents a numerical study incorporating the impact of temperature variations along the fracture on the viscosity of fracturing fluids and consequently on proppant distribution in hydraulic fracturing. Traditional models have not considered non-

The Calculation of Coal Rock Fracture Conductivity with Different Arrangements of Proppants

Geofluids, 2018
An accurate evaluation of coal rock fracture conductivity is an important prerequisite for predicting the productivity of CBM wells. Coal rock is soft and fragile, with low elastic modulus and high Poisson ratio.

Study on Proppant Transport and Placement in Shale Gas Main Fractures

Energies
In this paper, based on the background of a deep shale reservoir, a solid–liquid two-phase flow model suitable for proppant and fracturing fluid flow was established based on the Euler method, and a large-scale fracture model was established.
