deeper into the formation to eliminate the “phase trapping”. Thus, fracturing fluid can flowback “easier” and more efficient, in this way, the regained permeability to gas is increased [15-21]. We hereby study nanoemulsion and their physical chemical properties. Two flowback recovery test apparatuses have been constructed, sand packed column with saturated test fluid driven by fluid

The ,chemical, engineering objectives of a ,fracturing fluid, fall into three categories: Initiate and propagate a hydraulic fracture; Convey a propping agent into the fracture; and; Ensure the proppant pack and formation connect efficiently to the wellbore with minimal damage. Most optimization has historically concerned the first two points.

The physical and chemical properties of flowback water vary considerably depending on the geographic location of the play, the geological formation, and the chemicals introduced during the drilling and fracturing operations.” Also important is the fact that both flowback volume and water properties can vary throughout the lifetime of the well.

In a draft report on the potential impacts of fracking on drinking water, the U.S. Environmental Protection Agency (“EPA”) identifies vulnerabilities within the “,fracturing, water cycle,” but found no widespread, systemic problems. EPA divided what they call the “,fracturing, water cycle” into five stages: 1) water acquisition, 2) ,chemical, mixing, 3) well injection, 4) ,flowback, […]

Proppant ,flowback, following ,fracturing, treatments can be controlled by use of resin-coated proppant, inorganic fibers, or polymer strips. Each of these technologies has limitations. Resin-coated proppants cannot be used above 374 F and require an activator below 158 F. Thermoplastic strips cannot be used at temperatures above their melting point.

Total ,flowback, at Damme 3 from 20 November 2008 to 12 December 2009 amounted to 3,058 m 3 . The proportion of formation water, 69 %, and hydraulic ,fracturing fluid,, 31 %, in ,flowback, were derived from Fig. 3. This shows that only 945 m 3 of the hydraulic ,fracturing fluid, were recovered at this stage.

Analysis of the ,fluid, returned to the surface (,flowback fluid,) after hydraulic ,fracturing, indicates that as little as 30 to 45% of the guar-based polymer pumped during the treatment returned from the well during the ,flowback, period. 3 Polymer residues that remain in the fracture significantly contribute to lower proppant-pack permeability, leading to a loss in fracture treatment effectiveness. 1
