Computer Simulations of Proppant Transport in a Hydraulic Fracture
SPE Production & Facilities, 2001SummaryEquations of motion of a slurry in a narrow slot, such as a hydraulic fracture, are presented and solved numerically to obtain an estimate of the amount of gravity-driven vertical motion of proppant that can occur within a fracture during placement.Two types of gravity-driven motion are studied: settling of heavy-proppant particles; and ...

A Comprehensive Study of Proppant Transport in a Hydraulic Fracture
SPE Annual Technical Conference and Exhibition, 2015Abstract The effective placement of proppant in a fracture has a dominant effect on well productivity. Existing hydraulic fracture models simplify proppant transport calculations to varying degrees and are often found to over-predict propped or effective fracture lengths by 100 to 300%.

57th U.S. Rock Mechanics/Geomechanics Symposium, 2023
ABSTRACT The sand-carrying capacity of slickwater and the proppant transport capacity are the focus of unconventional reservoir fracturing research, but little attention has been paid to the effect of pump schedule on the proppant transport in fractures.

Surface Modification of Proppant to Improve Transport and Placement
International Petroleum Technology Conference, 2014Slick water hydraulic fracturing treatments are the preferred method for stimulation of tight hydrocarbon plays as these treatments enhance the complexity of fracture networks, increase fracture lengths, reduce formation damage and decrease treatment costs.

Proppant Transport by a High Viscosity Friction Reducer
SPE Hydraulic Fracturing Technology Conference and Exhibition, 2018Abstract Because of potential reduced cost and improved retained conductivity, high viscosity friction reducers (HVFRs) are becoming increasingly popular in hydraulic fracturing stages where linear or crosslinked guar gels are traditionally used.

Experimental and Numerical Modeling of Convective Proppant Transport
SPE Annual Technical Conference and Exhibition, 1994Abstract Slurry transport and settling experiments were conducted to improve current descriptions of proppant transport. Results of these experiments were used to formulate a new slurry transport model which was incorporated in a fully three-dimensional fracture simulator.

Viscoelasticity of Crosslinked Fracturing Fluids and Proppant Transport
SPE Production Operations Symposium, 1987ABSTRACT In hydraulic fracturing treatments, the success of the treatment strongly depends on the proper placement of the proppant particles in the fracture. By proper placement, one means the packing of the fracture to achieve maximum conductivity of gas/oil through the fracture into the wellbore.

Computer Simulations of Proppant Transport in a Hydraulic Fracture
SPE Western Regional Meeting, 1995Abstract The equations of motion of a slurry in a narrow slot, such as a hydraulic fracture, are presented and solved numerically to obtain an estimate of the amount of gravity-driven vertical motion of proppant that can occur within a fracture during placement.

Numerical Study of the Proppant Transportation in the Nonplanar Fracture
58th U.S. Rock Mechanics/Geomechanics SymposiumABSTRACT: The sand-carrying fluid flow in complex hydraulic fracture is crucial to improve the fracture conductivity. Previous research on proppant transportation simulation has mainly focused on planar fracture. This paper presents a proppant transportation model of the nonplanar fracture.

Proceedings, 2018
We present further development of the 2D two-continua model of proppant transport derived from first principles using the lubrication approximation [1]. The model includes effects associated with presence of the slip velocity between particles and fluid, as well the yield stress of carrying fluid.
