Real-time online fast and accurate measurement of drilling fluid performance parameters is
very important in the petroleum extraction process. At present, there are few studies on the …

As an important industrial material, bentonite has been widely applied in water-based
drilling fluids to create mud cakes to protect boreholes. However, the common mud cake is …

Quantum chemical calculations and mud filtration analysis were used to assess the
performance of three types of non-ionic surfactants as lubricating additives in synthetic …

In the red-bed areas of southwestern China, subgrade uplift deformation poses a serious
safety concern for high-speed trains. However, the subgrade uplift mechanisms are still not …

In our research described here, a rheological model was proposed to be used to determine
the rheological behavior of drilling mud, which is one of the most important factors in …

The operational safety of high-speed railways (HSRs) mainly relies on the flatness of their
track surfaces. In recent years, continuous and stable subgrade uplift deformations in red …

Rheological study of powder flow is a hot topic in recent years. This paper aims to provide a
novel alternative method for powder rheological characterization, instead of the …

The traditional way to mitigate loss circulation in drilling operations is to use preventative
and curative materials. However, it is difficult to quantify the amount of materials from every …

Calcium halide-based fluids are often used in drilling and completion operations due to their
high density, clay inhibition and low solid content. However, there is a lack of thickeners to …

In extended-reach and directional drilling, cuttings transport is a key issue associated with
the efficiency of hole-cleaning and drilling operation. If the cuttings cannot be returned to the …
