- Flowback fluid
A mixture of fracturing fluid and formation water that returns to the ground surface during and on completion of hydraulic fracturing job. Called also flowback water.
A set of grains of specific size (diameter). There are clay, silt, sand, gravel and boulder fractions (grain sizes: < 0.002 mm, 0.002-0.063 mm, 0.063- 2 mm, 2-63 mm, and 63-630 mm, respectively).
- Fracturing fluid
A fluid used in hydraulic fracturing operations, composed of water, proppant and chemical substances. Water and sand (proppant) account for 99.5% of fracturing fluid. The balance of 0.5% are chemical additives that are intended to improve the process of fracturing by decreasing friction, corrosion preventing and controlling bacterial growth.
