The mechanism of ultrasonic irradiation effect on viscosity variations of heavy crude oil

Ultrasonics Sonochemistry, 2021
Viscosity reduction of heavy oil has economic benefits and applicational value in the field. Applying viscosity reduction technology of heavy oil with ultrasound, this paper examines the influence of ultrasonic irradiation time and the addition of ...

Ozone-Assisted Micro-Nano Bubble Treatment of Oily Drilling Mud: Viscosity Reduction, Oil Removal, and Filtrate Reuse Performance

Applied Sciences
The treatment of high-viscosity oil-bearing drilling mud from offshore platforms is constrained by limited space and stringent environmental regulations, yet no previous study has demonstrated the combined application of ozone-assisted micro-nano bubble (

Study the Effect of Copper Oxide Nanoparticles on Reduce Crude Oil

Al-Qadisiyah Journal for Engineering Science, 2019
In the transportation of fluid, the drag reducers in pipeline are important parameters because of drag reduction increased the ability of pump fluid when adding small amounts of additive to fluid. The frictional pressure loss in pipes is waste energy and

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 ...

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%.

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 ...

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

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.
