A Comprehensive Study of Proppant Transport in a Hydraulic Fracture

SPE Annual Technical Conference and Exhibition, 2015
Abstract 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%.

Experimental and Numerical Modeling of Convective Proppant Transport

SPE Annual Technical Conference and Exhibition, 1994
Abstract 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.

Computer Simulations of Proppant Transport in a Hydraulic Fracture

SPE Production & Facilities, 2001
SummaryEquations 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 ...

Surface Modification of Proppant to Improve Transport and Placement

International Petroleum Technology Conference, 2014
Slick 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.

Viscoelasticity of Crosslinked Fracturing Fluids and Proppant Transport

SPE Production Operations Symposium, 1987
ABSTRACT 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, 1995
Abstract 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.

Does Higher Viscosity Improve Proppant Transport?

SPE Oklahoma City Oil and Gas Symposium, 2019
Abstract The use of high viscosity friction reducers (HVFR) as alternatives to guar-based fluids to improve proppant transport and lessen formation damage has increased rapidly. While several product options are available, the criteria for selection of a product has focused on viscosity at 300 RPM (511s-1) that meets or exceeds that of ...

Numerical Simulation of Proppant Transportation in the Nonplanar Fracture

International Geomechanics Conference
ABSTRACT: The fractures produced by hydraulic fracturing twist and extend in three-dimensional space, often forming complex nonplanar shapes, which makes the transportation law of proppant more complicated. To study the transportation law of proppant in the nonplanar fractures, the morphology of fracture propagation

Numerical Study of the Proppant Transportation in the Nonplanar Fracture

58th U.S. Rock Mechanics/Geomechanics Symposium
ABSTRACT: 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.
