fluid, that returns to the surface is referred to as ,flowback,, which is pumped into lined storage ponds prior to subsequent recycling or disposal (Figure 1). Hydraulic ,fracturing, requires large quantities of water because each well may be fractured multiple times and each ,fracturing, event can require hundreds of thousands of gallons of ,fluid,.

Hydraulic Fracturing Flowback Water Analysis Using In-Line ...

Following a fracturing event, the fracturing fluid withdrawn from the well is termed flowback and consists of the original fluid plus additional components that have been mobilized from the shale layer such as salts, metals, and radioisotopes. The high levels of dissolved salts leached from bedrock are a challenge to analyzing fracking

ing fluid is in the deposit, the more the change becomes visible. In the beginning the flowback water composition is close to the fracturing fluid composition. When the total volume of the obtained flowback water increases in time, the content of dissolved solid parts (TDS) increases up to 160 g/dm3 together with chloride content [13].

Evaluating Fracture-Fluid Flowback in Marcellus Using Data ...

Fracture-fluid flowback is defined herein as aqueous phase produced within 3 weeks following a fracture treatment (exclusive of well shut-in time). Field data from Marcellus shale wells in northeastern West Virginia indicated approximately 2 to 26% of the fracture fluid is recovered during flowback.

16/4/2020, · A fundamental principle used in all fracture models is that “the fracture volume is equal to the total volume of fluid injected minus the volume of fluid that leaks off into the reservoir.” [1] The fluid efficiency is the percentage of fluid that is still in the fracture at any point in time, when compared with the total volume injected at the same point in time.

During the course of fracturing fluid flowback, the fracturing fluid loss volume, V l, will change with bottom hole pressure P f. When the time is t n, the bottom hole pressure P f from t 1 to t n−1 is calculated. Therefore, V l n is the function of P n f.

The purpose of frac ,fluid flowback, is to outflow the ,fracturing fluid, and prevent the proppant backflow, which determines the effect of ,fracturing fluid flowback,. The ,fracturing, treatment in field lacks relevant theoretical models for prediction. Therefore, this work focuses on establishing the ,flowback, model of hydraulic ,fracturing, for multilayer fractured wells.
