Journal ArticleDOI
Numerical methods for hydraulic fracture propagation: a review of recent trends
TL;DR: A review of the basic approaches for hydraulic fracture simulation can be found in this article, where the authors discuss both continuum and meso-scales numerical methods as well as engineering models which typically make use of additional assumptions to reduce computational cost.

Role of proppant distribution on the evolution of hydraulic fracture conductivity
Jiehao Wang,Derek Elsworth +1 more
TL;DR: In this paper, a 2D model is presented to model the evolution of the residual aperture profile and conductivity of fractures partially/fully filled with proppant packs, and the model accommodates the mechanical response of proppers in response to closure of arbitrarily rough fractures.

A predictive model for steady-state multiphase pipe flow: Machine learning on lab data
TL;DR: A method of pressure drop calculation in the pipeline based on well segmentation and calculation of the pressure gradient in each segment using three surrogate models based on Machine Learning (ML) algorithms trained on a representative lab data set from the open literature.

Environmentally friendly techniques for high gas content thick coal seam stimulation─multi-discharge CO2 fracturing system
TL;DR: In this article, a multi-discharge CO2 fracturing system (Multi CO2 Frac) was proposed and tested in Changping coal mine, which can effectively improve coal seam permeability and further enhance gas drainage efficiency.
The Nature of Saltation and of Bed-Load Transport in Water
TL;DR: In this article, it has been shown that suspension by fluid turbulence of mineral solids larger than those of medium sands does not become appreciable until the bed shear stress is increased to a value exceeding 12 times its threshold value for the bed material considered.

Lift-off of a single particle in Newtonian and viscoelastic fluids by direct numerical simulation
TL;DR: The aim of the calculation is the determination of the critical lift-off condition and the evolution of the height, velocity and angular velocity of the particle as a function of the pressure gradient and material and geometric parameters.

Slurry flow, gravitational settling, and a proppant transport model for hydraulic fractures
Egor Dontsov,Anthony Peirce +1 more
TL;DR: In this article, the steady flow of a Newtonian fluid mixed with spherical particles in a channel was analyzed for the purpose of modelling proppant transport with gravitational settling in hydraulic fractures. But, these solutions require the numerical solution of an integral equation, and, as a result, the development of a propperant transport model for hydraulic fracturing based on these results is not practicable.

The inertial migration of non-neutrally buoyant spherical particles in two-dimensional shear flows
TL;DR: In this paper, the inertial migration of a small rigid spherical particle, suspended in a fluid flowing between two plane boundaries, is investigated theoretically to find the effect on the lateral motion, where the particle is non-neutrally buoyant and thus its buoyancy-induced motion may be either parallel or perpendicular to the channel boundaries, depending on the channel alignment.

Simulation of proppant transport with gravitational settling and fracture closure in a three-dimensional hydraulic fracturing simulator
Sogo Shiozawa,Mark W. McClure +1 more
TL;DR: In this article, a three-dimensional hydraulic fracturing simulator is used to investigate the effect of proppant settlement due to gravity, tip screen-out, and fracture closure, including a nonlinear joint closure law expressing fracture compliance and roughness.

Migration of rigid particles in non-Brownian viscous suspensions
TL;DR: In this paper, a two-fluid model was developed for particles dispersed in a viscous liquid and closed the model for rigid particles with the help of low-Reynolds-number hydrodynamics.
