A large amount of liquid is pumped into the shale gas reservoir during hydraulic ,fracturing,, and the ,fluid flowback, ratio is usually low. However, field experience showed that the liquids did not cause severe damage to shale gas reservoir. It is urgent to clarify the water block unlocking mechanism of a shale gas reservoir. This work is to discuss the water block unlocking mechanism in shale ...

This work describes the development of a solid-phase extraction method capable of detecting common ,fracturing fluid, additives in ,flowback, and produced water with mass spectrometry. Dissolved organic carbon (DOC) was used as a bulk measurement to investigate the retentive capacity of seven sorbents and to determine a loading volume.

The initiation and propagation of hydraulic fractures will cause stress redistribution and may activate natural fractures in the reservoir. Due to the limitation of the analytical method in calculation of induced stresses, we propose a numerical method, which incorporates the interaction of hydraulic fractures and the wellbore, and analyzes the stress distribution in the reservoir under ...

Fracturing, wastewater is often highly emulsified, viscous, and has a high chemical oxygen demand (COD), which makes it difficult to treat and recycle. Ferrate(VI) is a green oxidant that has a high redox potential and has been adopted for the efficient oxidation of ,fracturing, wastewater to achieve triple effects: demulsification, visbreaking, and COD removal.

The ,fluid, flow between the injection and production wells in one of the fractures is depicted in the figure using white dashed lines with arrows. Thus, the fracture-controlled production process can be studied from one wing of the fracture and the surrounding region, which can be represented by a horizontal two-dimensional (2D) computational domain as highlighted in the green box of Figure 1 .

Multistage hydraulic ,fracturing, is a key technique for the effective exploitation of tight reservoirs. In the process of multistage hydraulic ,fracturing,, a large amount of ,fracturing fluid, is injected into the formation. However, field data show that the ,flowback, rate of the ,fracturing fluid, after ,fracturing, is generally no higher than 30% [1].
