Determination of Cations in Hydraylic Fracturing Flowback ...
Determination of Cations in Hydraylic Fracturing Flowback ...

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.

Fracturing-Fluid Flowback Simulation with Consideration of ...

On the basis of the above-mentioned hydrodynamic ,flowback, behavior for ,fracturing,-,fluid,, following physical assumptions are made: (1) the physical ,flowback, model is composed of four interconnected domains, i.e., W, F, f, and m (as shown in Figure 2); (2) f and m form a dual-porosity media, which directly link F, and all F connect to W; (3) a set of fine grids with high permeability is used to ...

Flowback cleanup mechanisms of post-hydraulic fracturing ...

In hydraulic ,fracturing, operations, these agents are commonly used as an additive in ,fracturing fluid, to facilitate its backflow by reducing Pc and subsequently enhancing gas production. The results of this work recommend that using such agents enhances the gas production rate for ultratight formations but not for tight formations (it reduces the gas production rate).

There are multiple steps to properly handle hydraulic fracturing fluid. First, operators reuse flowback fluid for other wells, if possible. This reduces overall use of freshwater and reduces the amount of recovered water and chemicals that must be disposed of and reduces costs for the producer company.

A, flowback aid may be included in, the, fracturing fluid to reduce capillary pressure and water blocks,,, thereby improving the kinetics of the flowback and preventing, or, minimizing the leaving-behind of, any, substantial amount, of the, fracturing fluid,. Flowback aids, such as surfactants, have also been shown to aid in the “clean-up” of the proppant pack, thereby accelerating the flow of hydrocarbons through the …

Hydraulic Fracturing and Flowback Hazards Other than ...

Hydraulic ,fracturing, is a treatment process that stimulates well production in the upstream oil and gas industry. While not a new process, hydraulic ,fracturing, has been increasingly used in the last ten years due to the increase in horizontal well development, which requires ,multiple, stimulation stages per well. Hydraulic ,fracturing, involves

1/3/2021, · The decrease of the peak at smaller values of the relaxation time is small, which indicates that the, flowback of fracturing fluid, has been limited. Therefore, we can divide the, fracturing fluid, in the branch, fracture, into three types: free movable, water, in the, fracture,, restricted movable, water, under certain conditions, and retained, water.

16/4/2020, · The viscosity of the ,fracturing fluid, is an important point of differentiation in both the execution and in the expected fracture geometry. Many current practices, generally referred to as "slickwater" treatments, use low-viscosity fluids pumped at high rates to generate narrow, complex fractures with low-concentrations of propping agent (0.2-5 lbm proppant added (PPA) per gallon).
