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 ...

Widths of Hydraulic Fractures

open access: bronzeJournal of Petroleum Technology, 1961
Abstract A study of fluid mechanics, rupture of brittle materials and the theory of elastic deformation of rocks shows that, for a given formation, crack width is essentially controlled by fluid pressure drop in the fracture. Operating conditions which cause high pressure drop along the crack (such as high injection

Hydraulic Fracturing‐Induced Seismicity [PDF]

open access: yesReviews of Geophysics, 2020
AbstractHydraulic fracturing (HF) is a technique that is used for extracting petroleum resources from impermeable host rocks. In this process, fluid injected under high pressure causes fractures to propagate. This technique has been transformative for the hydrocarbon industry, unlocking otherwise stranded resources; however, environmental concerns make
