Abstract

Surfactant-type corrosion inhibitors are designed to adsorb to the internal surface of pipelines, forming a passive hydrogen layer to prevent access of corrosive liquid to the pipe surface. When dosed at a high enough concentration, the surfaces in the system will become saturated and inhibitor will accumulate in the production fluids forming aggregates known as corrosion inhibitor micelles. These form at the Critical Micelle Concentration (CMC). Solids originating from formation residues, corrosion by-products and scale formation can all provide secondary binding sites for corrosion inhibitor, leading to decreased availability and implications for system protection.

LUX Assure’s CoMic™ technology detects micelles in the water phase of an oilfield sample to provide information on inhibitor availability. It was used here to determine the effect of solids on inhibitor.

Abstract

Corrosion inhibitors used in the oilfield are generally formulations which consist of multiple chemical components. The surfactant molecules which provide the corrosion protection can contain different carbon chain lengths and/or different head groups (e.g. imidazoline, quaternary amine). CoMic™ detects micelles when a fluid contains surfactant above the critical micelle concentration (CMC) but what is the impact of the presence of multiple species? Do mixed micelles form where micelles are comprised of different surfactant molecules or do multiple CMCs exist?

Abstract

The development of a simple, easy to perform analytical method that uses robust equipment would overcome many of the issues encountered with gas chromatography and would be of particular benefit for use offshore or in remote locations where shipping of samples to an onshore laboratory is not practical. This paper describes a colorimetric method, called OMMICA™, for monitoring the concentration of thermodynamic hydrate inhibitors, methanol and MEG, in produced fluids, and includes results which demonstrate the specificity and sensitivity of the method. Data from offshore field trials showing OMMICA™ can be used in these environments and deliver reliable results is also presented.

Abstract

LUX Assure’s OMMICA™ method for measuring methanol and monoethylene glycol (MEG) in oil and water was compared to gas chromatography (GC) by a third party laboratory. The results demonstrate the accuracy of OMMICA™, providing clients with confidence to adopt the method for their operations.

Abstract

It’s understood that in certain MEG/water systems, such as MEG regeneration units, the presence of a number of different compounds poses a potential for interference with the OMMICA™ analysis method. To give customers confidence in the OMMICA™ method, a test matrix was completed to establish the effect of high concentrations of these compounds on MEG in water analysis results.
