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 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 ...

SPE/DOE Low Permeability Gas Reservoirs Symposium, 1985
ABSTRACT The results of fracture stimulation treatments implemented with and without propping agents in two reservoirs in England are compared. The effect upon the conductivity of proppant-free fractures of a minor departure of the wellbore axis from a principal stress plane is assessed.

SPE Hydraulic Fracturing Technology Conference, 2013
Abstract Presented here is a new approach to hydraulic fracturing, using proppants that self-suspend in water. To form these self-suspending proppants (SSP), conventional proppant particles are encapsulated with a thin layer of a high-molecular-weight hydrogel polymer, and then dried, yielding a free-flowing granular system that can be ...

SPE Annual Technical Conference and Exhibition, 1989
ABSTRACT A process for controlling proppant flowback after hydraulic fracturing operations has been developed and extensively field tested. In the procedure, fracture sand is coated with epoxy resin during the fracturing treatment. Unique wetting aids permit the rapid and complete epoxy resin coating of the sand while it is in the ...

Understanding Proppant Flowback
SPE Annual Technical Conference and Exhibition, 1999Abstract Proppant production from hydraulically fractured wells can cause severe operational problems, increase safety concerns, and dramatically reduce economic returns on well-stimulation investments. Methods that have helped eliminate or minimize proppant flowback include modified completion designs, the use of controlled fracture ...

Proppants, We Still Don't Need No Proppants - A Perspective of Several Operators
Proceedings of SPE Annual Technical Conference and Exhibition, 1998Abstract In SPE 38611 "Proppants, We Don't Need No Proppants" data showed that fracture treatments using treated water and very low proppant concentrations (waterfracs) were very successful in the East Texas Cotton Valley sandstone.

With the rise in hydraulic fracturing over the past decade has come a steep climb in proppant demand. Global supplies are currently tight. The number of proppant suppliers worldwide has increased since 2000 from a handful to well over 50 sand, ceramic proppant, and resin-coat producers. The estimated amount of proppant used has grown tenfold since 2000,
