A review on proppant transport modelling

Journal of Petroleum Science and Engineering, 2021
Abstract Proppant transport is a critical physical process in hydraulic fracturing which has been extensively used for reservoir stimulation in petroleum engineering. Proppants injected together with fracturing fluid provide structural support to the stimulated fracture network and prevent them from closing after flowback.

Numerical simulation of proppant transport in hydraulic fractures

Journal of Petroleum Science and Engineering, 2018
A central issue in hydraulic fracturing treatment in petroleum wells is the transport of proppant particles by the injection fluid. In this paper, we present an innovative proppant transport model in a fixed rectangular- and elliptic-shaped slots. The proposed model is an improvement to the current modeling of proppant transport by applying a non ...

Proppant transport study in fractures with intersections

Fuel, 2016
Abstract Slickwater fracturing is a popular stimulation treatment in the unconventional oil and gas industry. It creates thin and long fractures that connect to pre-existing natural fractures and generate complex fracture networks. A large fraction of the fractured area is not usually propped due to the high density of typical proppants (sand) and ...

Proppant transport in complex fracture networks – A review

Journal of Petroleum Science and Engineering, 2019
Abstract Hydraulic fracturing in shale resources often result in complex fracture networks due to the presence of natural fractures, bedding planes and/or low deviatoric in situ stress. Fracture treatments with low-viscosity slickwater are commonly used as a completion technique in the shale reservoirs which show poor proppant transport ...

Modeling Proppant Transport in Casing and Perforations Based on Proppant Transport Surface Tests

SPE Hydraulic Fracturing Technology Conference and Exhibition, 2022
Abstract The results of a series of proppant transport surface tests (PTSTs) were used in conjunction with Eulerian multiphase-computational fluid dynamics (EMP-CFD) modeling to develop an engineering model of proppant distribution. The PTSTs were carried out to evaluate proppant placement through perforated casing.

Foam-Proppant Transport

SPE Production & Facilities, 1997
Summary The rheology of foams has been the subject of recent work in which the principle of volume equalization has been proved to describe flow behavior effectively. In the present work this model is combined with the constant-internal-phase/constant-viscosity assumption to describe the transport of solid particles.

Proppant Transport of Fracturing Gels is Influenced by Proppant Type

SPE Hydraulic Fracturing Technology Conference, 2009
Abstract Fracturing gels are formulated to have a high viscosity sufficient to generate fracture geometry and transport proppant materials. Fracturing fluids are subjected to extensive QA/QC testing on high-temperature rheometers to ensure they have adequate viscosity to perform the intended task and break within a time frame suitable ...

Chemically Enhanced Proppant Transport

SPE Annual Technical Conference and Exhibition, 2014
Abstract Slick water hydraulic fracturing treatments are the preferred method for tight shale plays as they enhance the complexity of fracture networks that are needed to produce economic wells in unconventional formations. At their most basic, these treatments use a polyacrylamide friction reducer to allow for higher pumping rates, but ...

Proppant Selection for Shale Reservoirs: Optimizing Conductivity, Proppant Transport and Cost

SPE Unconventional Resources Conference Canada, 2013
Abstract In low-permeability reservoirs, hydraulic fracture design focuses more on creating fracture length than conductivity because hydraulic fracture surface area strongly influences production. In ultra-low permeability reservoirs such as shales, hydraulic fractures are designed to create complexity because the surface area in a ...
