Complex Fluids and Hydraulic Fracturing [PDF]

open access: yesAnnual Review of Chemical and Biomolecular Engineering, 2016
Nearly 70 years old, hydraulic fracturing is a core technique for stimulating hydrocarbon production in a majority of oil and gas reservoirs. Complex fluids are implemented in nearly every step of the fracturing process, most significantly to generate and sustain fractures and transport and distribute proppant particles during and following fluid ...
