Fracturing fluid retention in shale gas reservoirs ...
Fracturing fluid retention in shale gas reservoirs ...

Shale gas reservoirs are characterized by nano-Darcy permeability, rich organic matter, ultralow water saturation, developed bedding, and micro-fractures, leading to multi-scale transportation of shale gas. Multistage fracturing of horizontal wells is the main development technology to stimulate shale gas reservoirs, and tens of thousands of cubic meters of fluids are injected into the reservoir.

The ,flowback fluid, is separated from the natural gas or oil and stored at the wellsite. The well can flow (or produce) for years, but the ,flowback, of ,fluid, only occurs over days or months. The carefully recovered ,flowback fluid, is either reused for another well or disposed in government-approved facilities. Operators must track ,flowback fluid, ...

Based on the experimental and field data, fracturing ,fluid flowback, rates and gas production rates of 9 wells were analyzed. It is indicated that the same block follows an overall trend, namely, the lower the ,flowback, rates, the more developed the micro fractures, the better the volume simulation effect and the higher the gas production rates.

Hydraulic fracturing - Wikipedia

Hydraulic fracturing, also called fracking, fracing, hydrofracking, fraccing, frac'ing, and hydrofracturing, is a well stimulation technique involving the fracturing of bedrock formations by a pressurized liquid. The process involves the high-pressure injection of "fracking ,fluid," (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore ...

High amounts of ,fluid, wastes (,flowback, waters) are a result of hydraulic fracturing. After cracking a well, the ,fluid, is removed from the drillbore as well as from the cracks and gaps in the surrounding rock. As has been proved in American research, the amount of the ,fluid, obtained in shale gas fracturing is lower than in the case of
