.... Deoiling hydrocyclones can treat emulsions, high-pressure gas condensate water, high-turndown requirements, and work with pumps – however their fundamentals must still be adhered to for the system to work properly. Not all deoiler liners are the same and vendor experience is critical during evaluation...

... emulsion Introduction Heavy oil recovery techniques are generally dependent on utilization of a huge amount of heat to effectively decrease the viscosity and enhance the heavy oil recovery factor, such as conventional steam flooding and SAGD. The thermal recovery methods indeed assist oil industry...

... Abstract This study was performed to examine the efficacy of corn husks (CH) fine particles as potential natural demulsifier for breaking crude oil emulsion. Stable emulsions were formed using distilled water/crude oil and oil-water ratio was 4:6. The concentrations of CH particles ranging from...

Third, bulk emulsion stability was investigated by measuring the half-lives of the emulsions. Fourth, the interfacial...

... Abstract The formation of stable heavy oil emulsion, which may upset separation facilities and eventually lead to production impairment, is one of the most common issues encountered in the development of heavy oil reservoirs. This paper investigates the influence of various physicochemical...

... Abstract Coinjecting of steam with surfactant to recover heavy crude oil is studied. Performance production of this process is achieved through analysis of the formed emulsions which provides mechanistic understanding of crude oil and surfactant interaction in the presence of steam...

..., and on residual oil samples. Another flow assurance problem is emulsion formation which occurs widely in any steam processes. Hence, the emulsions formed during solvent-steam and steam experiments and the role of asphaltenes on emulsion formation are investigated. It has been observed that CO 2 enhances...

With well-established surfactant additives, the wettability of the OBM emulsion can be altered to improve the flow of hydrocarbons...

... Abstract Experimental observations regarding the formation of oil-water emulsions stabilized by nanoparticles and surfactants during oil production operations are presented. Similarities and differences between the two types of emulsions are discussed based on acquired separation profiles...

... evidence demonstrates that in many cases two-phase flow occurs by emulsification of one phase, e.g., injected water disperses as small micron size droplets within a continuous oil phase. Such emulsion flows yield results that contradict current doctrines; e.g., decline curves are not monotonic but have...

... agent and the density contrast between heavy oil and water is so low that heavy oil in porous media may flow by a continuous oil and stable emulsion phase. A part of the total oil flow occurs via oil phase that is similar to light oil and water system and the other part flow via a quasi-stable emulsion...
