Observations on Viscosity Reduction of PHPA Polymer Support Fluids [PDF]

Deep Foundations and Geotechnical In Situ Testing, 2010
Polymer fluids have been used in foundation drilling for many years and yet no previous studies have been reported which assess their sensitivity to shear such as is induced by pumping equipment. A field study has been carried out on two specific polymer products under actual site conditions.

Evaluation of viscosity reduction effect of oil-soluble viscosity reducer on crude oil

Journal of Physics: Conference Series, 2023
AbstractIn this paper, several crude oil viscosity reducers were selected to evaluate their performance on the heavy oil Henan Oilfield, China. Through investigation, the viscosity reducing ability of these viscosity reducers were relatively general. Among them, EVA had the highest performance, reaching a viscosity reduction rate of 45.6%.

Experimental Study on Surfactant–Polymer Flooding After Viscosity Reduction for Heavy Oil in Matured Reservoir

Energies
An advanced enhanced oil recovery (EOR) method was investigated, employing a surfactant–polymer (SP) system in combination with a viscosity reducer for application in a heavy oil reservoir within the Haiwaihe Block, Liaohe Oilfield, in China. Significant

Temporary Reduction of Viscosity of Liquids at High Rates of Shear [PDF]

Nature, 1951
IN view of a recent statement1 “that solutions of macromolecular substances may show an anomalous fall in the coefficient of viscosity at high rates of shear”, it is emphasized once again2 that, at sufficiently high rates of shear, any liquid consisting of elongated molecules must be expected to exhibit a decrease of the coefficient of viscosity with ...

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Investigating transcription factor dynamics in health and disease using FRAP

FEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Viscosity-reducing technology for high-viscosity produced fluid in binary combination flooding in Xinjiang Oilfield

You-qi chuyun, 2020
In the field chemical flooding test of the Qizhong District of Xinjiang Oilfield, emulsion with high apparentviscosity (4 000 mPa·s) was found in some well, without demulsification and viscosity reduction after placement inseveral days, which affected ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Research on Performance Optimisation and Viscosity-Reduction Mechanisms of Warm-Mix Rubber Asphalt Pavement Materials in Cold and Arid Regions

Applied Sciences
In cold and arid regions, the durability of asphalt pavement materials is often inadequate, and the hot mixing process further accelerates pavement ageing and releases harmful gases.

Discerning protein pools by selective staining with self‐labeling tags

FEBS Letters, EarlyView.
Cell surface proteins have an intra‐ and extracellular pool. Combining genetic fusion to self‐labeling tags that can be addressed with small molecule fluorophores allows separating these pools. We highlight recent developments and techniques for state‐of‐the‐art interrogation of cell surface proteins in the complex tissue setting.
