Polymer flooding is an enhanced oil recovery (EOR) method used to increase oil recovery
from oil reservoirs beyond primary and secondary recovery. Although it is one of the most …

Polymer flooding is an effective method widely applied for enhancing oil recovery (EOR) by
reducing the mobility ratio between the injected water and crude oil. However, traditional …

During polymer flooding, the velocities where shear-thickening occurs directly impact HPAM
injectivity, fracture initiation, and whether viscoelasticity is significant in oil recovery. The …

In the pharmaceutical industry, tablets are a common dosage form. As part of the
manufacturing process, powder in a tablet press passes through a feeding system called the …

Polymer flooding is crucial in hydrocarbon production, increasing oil recovery by improving
the water-oil mobility ratio. However, the high viscosity of displacing fluid may cause …

As mature oilfields enter the high-water-cut development stage, significant amounts of
residual oil remain trapped underground. To enhance the effectiveness of tertiary oil …

Induced fractures often play a key role in achieving acceptable injectivity during polymer
floods, especially for vertical injection wells. However, fracture extension must be controlled …

The most pressing question to embark on polymer flood projects is whether a polymer can
be injected at economic rates while below reservoir parting pressure. There are several …

The Gasi reservoir in the Qinghai oilfield is a typical high-temperature and high-salinity
reservoir, with an average temperature and average salinity of 70.0 C and 152,144 mg/L …

We numerically study mechanisms and conditions of fracture initiation in granular material
induced by non-Newtonian polymer solutions. A coupling approach of computational fluid …
