Volatile organic constituents have been shown to be present in ,fracturing fluid flowback, wastes at levels that exceed drinking water standards. For example, testing of ,flowback, samples from Texas have revealed concentrations of 1,2-Dichloroethane at 1,580 ppb, which is more than 316 times EPA’s Maximum Contaminant Level for 1,2-Dichloroethane in drinking water .

Centralised sites deliver fracking water efficiency - WWT

T he number of hydraulic ,fracturing, (fracking) shale oil and gas wells in the US and worldwide continues to increase. However, as more come into operation, so does the stress on surface water and groundwater supplies. Up to 3,785m 3 of fresh water per wellhead is required to carry out the fracking process alone. Equally important is the growing volume of wastewater generated from fracking ...

The object of the paper is the prediction of ,flowback fluid, composition at a laboratory scale, for which a new approach is described. The authors define leaching as a ,flowback fluid, generation related to the shale processing. In the first step shale rock was characterized using X-ray fluorescence spectroscopy, X-ray diffractometry and laboratory analysis. It was proven that shale rock samples ...

During oil and natural ,gas production,, so-called “produced water” comprises the largest byproduct stream. In addition, many oil and gas operations are augmented via injection of hydraulic ,fracturing, (HF) fluids into the formation. Both produced water and HF fluids may contain hundreds of individual chemicals, some known to be detrimental to public health and the environment.

Abstract: Hydraulic ,fracturing, is considered as an effective approach for the development of tight oil reservoirs. Unlike conventional reservoirs, after a large volume injection of the ,fracturing fluid,, the ,flowback, rate in tight oil reservoirs is considerably lower whereas the underlying mechanism explaining water retention remains unclear.
