Green Fracturing Technology of Shale Gas: LPG Waterless ...

Shale gas is being widely exploited in ,Sichuan, Province, which is located at the source of Yangtze River. In Ordos Basin limited water sources make it very costly to prepare conventional ,fracturing, fluids. The slickwater ,fracturing fluid, is cheaper than the LPG ,fracturing fluid,, while water ,treatment, costs more.

Removal of organics from shale gas fracturing flowback ...

Shale gas ,fracturing flowback fluid, contains various degradation difficulty organic compounds after hydraulic ,fracturing,. A hybrid ,treatment, method was developed for treating ,flowback, and produced water (FPW) using pre-,treatment, (NaClO) followed by the expanded granular sludge bed (EGSB) and moving bed biofilm reactor (MBBR). Gas chromatography–mass spectrometry (GC-MS) was employed to ...

Successful Treatment and Reuse of Flowback Guar Frac-Fluid ...

However, ,treatment, and reuse of commonly used guar frac ,fluid, system remains a significant challenge to operators and service companies. To successfully treat and reuse ,flowback fluid, in Ordos basin, two major obstacles have to be overcome: First, in the ,fracturing, process, the local common practice is to add the entire designed amount of gel breaker at the end of propant pumping job, to avoid ...

Characterization of hydraulic ,fracturing flowback, and produced water (HF-FPW) is an important initial step in efforts to determine a suitable ,treatment, method for this type of wastewater. In the present study, ,fracturing flowback, and produced water samples were obtained from well CN-F and well CN-E in the prophase and anaphase stages of the Changning shale gas mining area.

Application of ozone for ,flowback, water ,treatment,. The studied ,flowback, water had low ozone demand with 44 mg O 3 /L consumed during 60 min, whereas 300 mg O 3 /L was applied. Foaming was observed at the beginning of the experiment, possibly caused by the presence of surfactants originated from ,fracturing fluid,.

Common chemical additives in ,fracturing fluid, are often surfactants [7,34,36,37,38]. Generally, they are intended to increase the viscosity of ,fracturing fluid, to allow it to propagate within the target formation. An anionic surfactant that is added in ,fracturing fluid, mixture is Internal Olefin Sulfate (IOS) [34].
