... Abstract Critical micelle concentration (CMC) is a known indicator for surfactants such as corrosion inhibitors ability to partition from two phase systems such as oil and water. Most corrosion inhibitors are surface active and at critical micelle concentration, the chemical is partitioned...

...ABSTRACT ABSTRACT Corrosion inhibition is a highly effective strategy for mitigating metal degradation. However, the effect of high temperature on inhibitor effectiveness is not well documented in the literature. More specifically, the concept of critical micelle concentration (CMC), often used...

... number of alkyl chain carbon (12, 14, 16) at a series of salinity (0.1%, 1% and 10% wt. NaCl) and temperature (30°C, 50°C and 70°C). Each test condition evaluated seven accumulation concentrations of surfactants ranging from 0.1 to 10 times the critical micelle concentrations (CMC) that were determined...

...Procedure Abstract The critical micelle concentration (CMC) of surfactants represent the concentration at which surfactant monomers start to form aggregates in order to minimize the energy of the electrostatic and hydrophobic interactions of the system. At this concentration, any additional...

..., leading to false failures in the secondary property testing phase and otherwise good candidates being dismissed. This paper describes a method of exploiting the critical micelle concentration (CMC) of the corrosion inhibitors to show that the use of CMC can be used as a laboratory screening method...

... ABSTRACT Following our preceding papers on the theoretical underpinnings and laboratory development of the micelle detection method, this paper will describe a variety of case studies where it has been applied to systems to investigate the field-relevant functional dose of corrosion inhibitor...

... Abstract This paper builds on the evidence for the optimum dose of organic film-forming corrosion inhibitor (FCCI) being at the critical micelle concentration (CMC) of the surfactant components, and the concept of micelle detection as a tool for understanding the effectiveness of the inhibitor...

... to coincide with the formation of surfactant droplets (micelles) in solution at the Critical Micelle Concentration (CMC). Following the initial investigations described at Corrosion 2011, this paper reports on development of a micelle detection instrument which identifies individual particles in a flowing...

... and form a protective barrier against corrosion. Upon saturation of surfaces by the inhibitor, the molecules are found in the aqueous phase as micelles or in the oil phase as reverse micelles. The proposed technique is based on the hypothesis that the presence of these micelles in the water phase could...

... production and recovery enhancement by injecting an improved micelle dispersions system. According to lab test, this colloidal dispersion system is a pseudoplastic fluid with temperature tolerance, salinity tolerance, shearing resistance, stability and low cost. The lab experiment result shows oil recovery...

... SPE Member Abstract Surfactants are used at high temperatures as additives for steamfloods. and in high-temperature surfactant floods. Most surfactants must be above the critical micelle concentration (CMC) in order to have appropriate properties for forming foams or mobilizing oil. The CMC...

... Abstract The formation of corrosion inhibitor micelles in produced water can be used as an indicator of optimal dosage in a system. Prior to field use, tests are conducted in the laboratory on the relevant corrosion inhibitor, ideally in the presence of field hydrocarbon and other production...
