Proppant transport in underground fractures plays a key role mitigating sand screen-out and enhancing the stimulated production for hydraulic fracturing. The effects of field pumping schedules, however, are not fully studied. We investigate effect slickwater-alternate-slurry injection on proppant at field-practical scales. A new hybrid approach is proposed to directly connect experimental studi...

Abstract Some of the most promising potential applications nanotechnology to hydraulic fracturing coal seam gas (CSG) are reviewed with a focus on Australian CSG wells. Three propitious were identified: (1) Nanoparticle enhanced viscoelastic surfactants (VES) fluids prevent fluid loss by up 30%, made possible formation pseudo-filter cakes and reducing viscosity VES fluids. Besides, there is no ...

Investigating the key factors that impact fluid rheology and proppant static settling velocity in high viscosity friction reducers (HVFRs) is a critical aspect for successful transport hydraulic fracture treatment. In this study, rheological properties of HVFRs were tested at various temperature ranges (i.e., 25, 50, 75, 100 °C) different HVFR concentrations 1, 2, 4, 8 gpt). Three sizes spheric...
