can increase extraction rates and ,recovery, of fossil fuels (Ryan, 2012). The injected ,fluid, is typically a slurry of water, so-called proppants, and chemical additives. The proppant is a mixture of durable solids, often containing grains of sand, ceramic, or other particulates that prevent fractures from closing when the ,fluid, injection is halted.

1/2/2019, · Indeed, surfactant is usually used as an additive to reduce the capillary trap of the ,fluid, in rock matrix to promote the ,flowback, of ,fracturing, fluids (Jiang et al., 2013). The reason is that DR of surfactants results from rod-like micelles produced by association, which is not stable by itself.

Drilling lengths and fracture ,treatment, volumes are increasing proportionally faster than IP rates are in most resource plays, increasing extraction intensity . Although production initially increases per well as operators drill out the most productive areas first, productivity for new wells eventually starts to fall. The median IP rate for 2012 vintage wells in the Barnett was only 1,650 Mcf/day, a 22% drop compared …
