Properties of Crude Oil-in-Water and Water-in-Crude Oil …
2021年12月23日 · In this work, a critical review was carried out to assess the main principles that affect an emulsion, how the flow patterns are influenced by the water fraction, which equations can be used to estimate the main physical properties, and last what are the methods or techniques for identifying or characterizing an emulsion.
Sampling and Analysis of Crude Oils for Water Content One fundamental purpose of sampling is to verify online WIC analyzers (Water-In-Crude analyzers or Water-In-Condensate analyzers) are providing accurate indications of water content. The method to determine water content must be carefully considered by observing the types of crude oil ...
Oil-in-water and water-in-oil emulsions formation and demulsification
2022年3月1日 · Depending on operating conditions and fluid components, crude oils can form stable emulsions with water. In fact, some of the oil's compounds can act as natural surfactants, decreasing the interfacial tension between fluids, promoting emulsification.
Properties and Instability Dynamics of Water-in-Crude Oil …
3 天之前 · Due to the influence of active substances such as resin and asphaltene in crude oil and flow shear, a large amount of water-in-crude oil (W/O) emulsions would be formed in the porous media during reservoir development. To achieve highly efficient development, the emulsification and stabilization mechanisms of W/O emulsions are studied from three aspects: the emulsification dynamics of oil and ...
An Improved Method for Measuring the Distribution of Water
Although water and crude oil are often considered as two immiscible phases, crude oil generally contains water droplets due to the existence of natural interfacial active substances (mainly asphaltenes) in crude oil [1,2,3].Water droplets may be generated during crude oil exploration and transportation [4,5], as the turbulence and agitation may …
Properties of Crude Oil-in-Water and Water-in-Crude Oil Emulsions…
2021年12月23日 · This study tries to assess the correlation between aging time, water cut, crude oil viscosity, water viscosity and amount of solids and viscosity of petroleum emulsions.
Water-in-oil emulsion stability and demulsification via surface …
2022年2月1日 · During crude oil production, stable water is formed in oil emulsions, especially with higher content of asphaltenes. In oil industry, the accepted content of water in crude oil is less than 0.5%. Thus, breaking emulsion into two phases before transportation and refining processes is necessary.
Measurements and interpretation of crude Oil-Water/Brine …
2022年5月1日 · This study provides a large database of crude oil-water/brine IFTs encompassing reservoir conditions of temperature and pressure. Specific effects of temperature, pressure, and fluid composition on the crude oil-water and oil-brine IFTs were evaluated.
Stability and Destabilization of Water-in-Crude Oil Emulsion
2021年4月2日 · The water-in-oil crude oil emulsions are stable because of a film formed by some surface-active molecule (high molecular weight polar molecules) around the water droplets at the water-oil interface. The interfacial films increase the interfacial viscosity, which retards the rate of separation of water.
Two-Phase Crude Oil–Water Flow Through Different Pipes: An …
The present study deals with two-phase non-Newtonian pseudoplastic crude oil and water flow inside horizontal pipes simulated by ANSYS. The study helps predict velocity and velocity profiles, as we...
