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

Although new energy has been widely used in our lives, oil is still one of the main energy
sources in the world. After the application of traditional oil recovery methods, there are still a …

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 …

With the increasing depth of reservoir development, the temperature and shear resistance of
fracturing fluids needs to be further improved. In comparison with traditional crosslinking …

Water-based drilling fluids are extensively used for drilling oil and gas wells. However, water-
based muds cause clay swelling, which severely affects the stability of wellbore. Due to two …

To develop high-salinity, high-temperature reservoirs, a novel supramolecular viscoelastic
polymer-based fracturing fluid modified with an amphiphilic functional monomer was …

In this paper, a betaine-based gel containing 2.0% erucamide propyl betaine (EAPB), 0.5%
oleic acid amide propyl betaine (OAPB), and 0.1% KCl was prepared for use as a fracturing …

In order to develop a special surfactant that is suitable for improving oil recovery in low
permeability reservoirs, and simultaneously meet the requirements of effectively improving …

In this study, the newly extended Gemini surfactants (EGSs) were studied as potential
candidates in the petroleum industry applications. The performances of EGSs with respect to …

Recently, viscoelastic surfactant (VES) fracturing fluids have attracted wide attention
because they are highly viscoelastic and environmentally benign. To optimize fracturing fluid …
