1、Section 4 Properties of Crude Oils (原油,Solution Gas-Oil Ratio (溶解气油比) Formation Volume Factor of Oil (原油的体积系数) Total formation factor(两相体积系数) Specific Gravity of a Liquid (液体的比重) The Coefficient of Isothermal Compressibility of Oil (原油的等温压缩系数) Oil Viscosity...
Properties of crude oil from four indigenous oilseeds in Africa (Kenya) were determined and their potential use as fuel, lubricants, hydraulic fluids, and brake fluids were evaluated. The oils were extracted chemically and mechanically using petroleum ether and ram press respectively. The properties ...
The concentration of surface aqueous species could be calculated using PHREEQC- a geochemical tool28- it considers oil/brine surface reactions and acts them just like other surface reactions such as rock/brine but it does not consider the impact of oil properties, e.g., acid/base number, and...
When an oil spill occurs,there is an immediate need on the part of spill responders to know the properties of the spilled oil,as these will affect the behavior,fate,and effects of the oil,which will in turn affect the choice of countermeasures.However,it is often difficult or impossible to...
The formulated crude O/W nanoemulsions were extremely stable with 0% oil or water separation even after a month of storage. Despite the extreme stability of these crude O/W nanoemulsions, they could be easily switched off (i.e., demulsified) within 1 h by pH-swing via the addition of ...
A key question discussed in detail below is whether the craniofacial malformations represent a novel activity of crude oil, or can be explained by the known effects of crude oil-derived PAHs on intracellular calcium handling. Finally, these studies highlight the unique properties of the haddock ...
However, the rheological properties for petroleum oils are very necessary for all the transfer processes of fluids from one location to another. Indeed, the rheological properties are considered as one of the main parameters governing the transportation of crude oil or petroleum oils in good ...
浅析国际原油升贴水与原油性质关系 analysis of relationship between agio and properties of imports crude oil 热度: Update on Overseas Investments by China´s National Oil Companies(PDF-49) 热度: Nonlinear causality between crude oil price and exchange rate A comparative study of China and India ...
The injection of low-salinity brine enhances oil recovery by altering the mineral wettability in carbonate reservoirs. However, the reported effectiveness of low-salinity water varies significantly in the literature, and the underlying mechanism of wettability alteration is controversial. In this work, we...
Rheological properties for petroleum oils are very useful for all processes in which fluids are transferred from one location to another. For example, the crude oil migration within the oil reservoir requires the fluid viscosity of the migrating oils. Other examples for the demand of the crude oil...
