Some of the ,fluid, returns to the surface as ‘,flowback, water’. Fracking ,fluid, consists mainly of water and sand, which acts as ‘proppant’ to keep fractures open. Small quantities of chemicals are added (usually less than 0.5%) to enable the ,fluid, to pass easily through fractures, to kill bacteria and to prevent build up of scale in the well.

Unconventional Fracturing Fluids: What Where and Why
Unconventional Fracturing Fluids: What Where and Why

conventional ,fracturing, fluids causes water to be trapped in the near‐ wellbore region, thereby significantly impairing the ability of gas to flow. Formations with sub‐ irreducible water saturation can be stimulated with fluids that minimize the interfacial tension

19/11/2014, · As mentioned above, the clear ,fracturing flowback fluid, is mainly composed of VES which is usually cationic ammonium surfactant and AOS is anionic. When cationic and anionic surfactants are used together, the strong electrostatic attraction leads to the adsorption of more surfactant molecules on the oil/water interface [36] , which results in the appearance of lowest IFT in mixed catanionic systems.

Comparing to the original fracturing fluid whose density was 1.30 g/cc, the density of the flowback fluid decreased with time, indicating the loss of weighting agent into the formation. When the flowback fluid is reused, additional weighting agent might be needed depending on the fracturing job; however, the dosage can be less than the case using the fresh water.
