Hydraulic fracturing integrates key technologies assisting in the establishment, increase,
and stabilization of gas and oil production. In particular, the performance of the working …

The vulnerable corrosion resistance of Mg alloys is regarded as one of the main
disadvantages restricting their application, while it can be used as an extraordinary specialty …

The physics of proppant transport in fractured reservoirs is of great interest to the oil and gas
industry; nevertheless, the outcomes are controversial. This study provides a comprehensive …

Improved oil recovery (IOR) includes enhanced oil recovery (EOR) and other technologies
(ie fracturing, water injection optimization, etc.), have become important methods to increase …

Controlling viscosity of aqueous surfactant solutions is very important for practical
formulations. This can be done by having polymers interact with surfactants, thereby forming …

A viscoelastic surfactant (VES) fluid is an important part of a water-based fracturing fluid. As
oil and gas exploration expands into deep, high-temperature, low-permeability reservoirs …

Viscoelastic surfactants (VES) are amphiphilic molecules which self-assemble into long
polymer-like aggregates—wormlike micelles. Such micellar chains form an entangled …

A hydrophobic associative water-soluble polymer, SRHV, was designed and synthesized in
this study. The CAC of SRHV was 0.072 wt% and 0.2 wt%. The scanning electron …

Osmotic pressure (P osmotic) is an important mechanism for fracturing fluid loss in clay-rich
unconventional reservoirs. Surfactant is often added to the fracturing fluid to control this loss …

Slick water fracturing fluid is widely used for fracturing unconventional reservoirs such as
shale and tight gas, and it has aided in developing unconventional oil and gas reservoirs …
