However, field data show that the flowback rate of the fracturing fluid after fracturing is generally no higher than 30% [1]. For conventional reservoir hydraulic fracturing, the flowback rate should be higher to reduce the damage caused by the external fluids to the reservoir [ 2 – 4 ].

Although shale gas resources are abundant in China but the extremely low permeability impedes its extraction from shale. In order to effectively develop shale gas reservoirs,SRV(stimulated reservoir volume),fracturing, is generally adopted to expand the seepage area;however,in most cases,the ,fracturing flowback rate, is low.To solve this problem,we analyzed the gas shale components and …

19/11/2014, · In laboratory, clear fracturing flowback fluids was obtained by simulating the actual gelling and gel breaking process during fracturing construction in the field. The gelling fluid was prepared with 4 wt% VES and 96 wt% formation water. The gel breaking process was realized by adding 2 wt% kerosene into the gelling system.

5/6/2015, · Two commonly used terms, ,flowback, water and produced water, have been used when addressing ,hydraulic fracturing, samples. The ,flowback, water is the immediate return of injected fracking fluids, and the produced water is the term used to describe the water that is mixed with formation water (native to the well) and returns at a later time, during the production of oil and gas recovery.

Hydraulic fracturing in the United States - Wikipedia

Hydraulic fracturing in the United States, began in 1949. According to the Department of Energy (DOE), by 2013 at least two million oil and gas wells in the US had been hydraulically fractured, and that of new wells being drilled, up to 95% are hydraulically fractured.The output from these wells makes up 43% of the oil production and 67% of the natural gas production in the United States.

This mixture, called ,fracturing fluid,, creates fissures in the shale increasing its permeability and gas recovery. The mixture of the injected ,fracturing fluid, together with the connate water of the formation, which returns to the surface within few weeks after pressure being released, is called ,flowback, water (Olmstead et al., 2013).
