Reasons for the low flowback rates of fracturing fluids in ...

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 stimulation effect and the higher the gas production rates.

Flowback water, (aka backflow water) is the murky, salty water from fracing natural gas wells. It consists of frac ,fluid, which returns to the surface (aka the frac load recovery) as well as produced water.This water contains clay, dirt, metals, chemicals and even diesel that may have been added. The frac load recovery can be anywhere from 15-40% percent of the volume of ,fluid, that is injected ...

The possibility of desalinated water production from hydraulic ,fracturing flowback, by electrodialysis reversal (EDR) was investigated. To simulate geochemical reactions of hydraulic ,fracturing fluid, with the formation rocks, ,fluid,-gas-rock reaction was performed in autoclave. Next, an EDR of hydraulic ,fracturing flowback, was simulated and the composition of diluate and concentrate was ...

Energizing the ,fluid, creates a high gas saturation in the invaded zone, thereby facilitating gas ,flowback,. It is estimated that one-third of the fractures pumped in the US are energized by a gaseous phase. Energized-,fluid fracturing, is common in reservoirs that are water sensitive or that have a low pore pressure or low permeability.

A Two-Phase Flowback Model for Multiscale Diffusion and ...

A shale gas reservoir is usually hydraulically fractured to enhance its gas production. When the injection of water-based ,fracturing fluid, is stopped, a two-phase ,flowback, is observed at the wellbore of the shale gas reservoir. So far, how this water production affects the long-term gas recovery of this fractured shale gas reservoir has not been clear.

Mechanism. Hydraulic ,fracturing, is the process of pumping ,fluid, into a wellbore at an injection rate too high for the formation to accept without breaking. During injection, the formation’s resistance to flow increases, and the pressure in the wellbore increases to a value called the break-down pressure, which is the sum of the in-situ compressive stress and the strength of the formation.

As the ,fracturing, process proceeds, viscosity-reducing agents such as oxidizers and enzyme breakers are sometimes added to the ,fracturing fluid, to deactivate the gelling agents and encourage ,flowback,. Such oxidizers react with and break down the gel, reducing the ,fluid,'s viscosity and ensuring that no proppant is pulled from the formation.
