Proppant transport study in fractures with intersections
Fuel, 2016Abstract 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, 2019Abstract 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, 2022Abstract 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.

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, 2009Abstract 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, 2014Abstract 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, 2013Abstract 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 ...

Prediction of Proppant Transport From Rheological Data
SPE Production & Operations, 2008Summary To ensure that a fracturing treatment will be successful, fracturing gels are formulated and viscosity parameters are measured. Steady-shear viscosity cannot measure the elastic component of viscoelas-tic fluids. Dynamic-oscillatory shear can provide measurements of elastic properties, but such measurements are made in the ...

Novotny, E.J., Member of SPE-AIME, Exxon Production Research Co. Abstract A method is presented for predicting:the transport of proppant in a vertical fracture during a hydraulic fracturing treatment,the settling of the proppant during closure of the fracture following the treatment, andfrom the final

Proceedings of SPE Annual Technical Conference and Exhibition, 2005
Abstract Beyond the initial fracture propagation, the primary function of fracturing fluids is to provide the means and media for the transport and placement of a conductive proppant pack in the created fracture such that resident hydrocarbons may be more easily produced. That is after all, the objective of hydraulic fracture stimulation.
