The use of gels in oil production processes has become a regular practice in oilfield
operations and is constantly developing in all oil-producing countries of the world, as …

Slickwater-based fracturing fluid has recently garnered significant attention as the major fluid
for volumetric fracturing; however, lots of challenges and limitations such as low viscosity …

Researchers have investigated the phenomenon of flow drag reduction by polymers for
more than 70 years. A lot of progress has been made on understanding the physical process …

Water-soluble polymers as drag reducers have been widely utilized in slick-water for
fracturing shale oil and gas reservoirs. However, the low viscosity characteristics, high …

In contrast to the field effect of guar gum fracturing fluid, the polymer gel fracturing fluid
causes a different production phenomenon. There is a lag between fracturing and the …

In the process of the large-scale hydraulic fracturing development in oil and gas fields,
reservoir damage caused by polymer fracturing fluid is inevitable. The real oil and gas field …

Water invasion, associated with hydraulic fracturing, often causes hydrocarbon-mobility
hindrance, known as water blocking. The effect on productivity is largely dependent on …

Adding a small amount of polymers can achieve significant drag reduction effects. However,
for external flows, the common homogeneous mixing and diffusing injection methods are not …

Produced waters are brines drawn during the oil and gas production. These fluids are often
re-injected into unconventional reservoirs along with certain additives and proppants in …

The development of advanced anti-salt drag reduction (DR) agents is crucial for enhancing
oil recovery rates, particularly in highly mineralized saline water where the network structure …
