16/4/2020, · If too much fluid leaks off, the fluid has a low efficiency (10 to 20%), and the created fracture volume will be only a small fraction of the total volume injected. However, if the fluid efficiency is too high (80 to 90%), the fracture will not close rapidly after the treatment.

Choosing The Correct Flow Meters For Hydraulic Fracturing

Hydraulic ,Fracturing, is the process of creating fractures in a rock layer to release trapped natural gas. Hydraulic ,fracturing, is done by drilling horizontally through a rock layer and injecting a pressurized solution comprised of water, a proppant, and a chemical solution. This solution is sometimes referred to as frac ,fluid,.

It is verified by XRD and infrared spectroscopy that the fracturing fluid doesn't flow into the space between clay mineral layers, so it can't lead to shale swelling. Thus, the retention of fracturing fluids is mainly caused by the adsorption at the surface of the newly fractured micro fractures in shale in a mode of successive permeation, and its adsorptive saturation rates is proportional to the, pore diameters.

Surprisingly, a phenomenon that a low flowback rate of HFF usually yields a, high gas production rate, is found recently by field data studies. In this case, the authors investigated the reasons for this abnormal phenomenon and believed that reducing the flowback rate of HFF in a shale gas reservoir could be a new strategy for dealing with the injected HFF.

There are two main reasons for performing this type of stimulation treatment: First and foremost is low permeability, where natural production is not economical; a conductive fracture provides much more flow area for produced fluid or gas.
