Waxy crude oil is characterized by high pour point and poor flow properties, which bring great difficulty to the oil exploitation and transportation. In this study, the fluidity of waxy crude oil with the pour point of 47掳C was highly improved by emulsification with synthetic formation water ...
PVTx thermal dynamics simulation of reservoir fluid inclusions has been applied to restore trapping pressures by inclusion component, homogenization temperature and gas liquid ratio combined with simulation software. In Gaotaizi tight reservoir in Qijia area of Songliao Basin, the hydrocarbon charging even...
Scientists are confident about the formation of coal, but they do not seem so sure when asked about oil. They think that the oil under the surface of the earth originated in the distant past, and was formed from living things in the sea. Countless billions of minute sea creatures and plan...

In the event of oil spills in the marine environment, oil undergoes a number of weathering processes altering the physical and chemical nature of the oil. One of the most important processes in weathering is the formation of oil-in-water dispersions, as this increases the surface to volume rat...
Oil and natural gas formation Source: EIA Types of Fossil Fuels Oil Oil is generally a liquid and consists mainly of hydrogen and carbon, and is therefore known as a hydrocarbon. Even within this one class of fossil fuels, there are many varieties of oil, because various deposits of oil ...
Based on the self-development crude oil depressurization foaming device and the CO2 flooding crude oil, this paper studies the evolution of foam and analyzes the function mechanism of asphaltene and wax crystal on defoaming and drainage of crude oil quantitatively. The experimental results show a ...
As the second-largest oil producer and natural gas exporter, Russia’s war with Ukraine has severely impacted the energy market. To what extent has the war influenced crude oil prices, and has it altered the long-term dynamics of oil prices? An objective analysis of the effects of the Russi...
An improvement of the flow properties of paraffin-containing crude oil, more specifically, a means of favourably influencing the pour point of crude oil and hence improving the flow
