Brine Chemistry Solutions is beginning phase two of a project researching corrosion and scale prediction. The corrosion and cathodic protection study will examine prevention in extreme pressure and temperature environments that could make drilling operations in the Gulf of Mexico safer and more productive.
Brine Chemistry Solutions, a Houston-based researcher of water chemistry issues in the energy industry, announced it has begun phase two of a research project that will evaluate corrosion and scale prediction and prevention at extreme pressure and temperature (xHP/HT).
Phase one of the research involved conducting experiments with instrumentation capable of studying corrosion and scale formation at up to 24,000 psi and 250°C (482°F). Phase one produced methodology and data that will be used in phase two to further develop the company’s models.
Phase two will include additional xHP/HT testing of corrosion and scale in additional alloy types and complex brine systems and will screen multiple inhibitors for thermal stability and effectiveness.
Brine Chemistry Solutions will use an autoclave reactor, proprietary flow-through apparatus, and vertical scanning interferometry to focus on kinetics and behavior at xHP/HT while simultaneously studying the thermal stability of inhibitors.
Modeling during phase two will also focus on solvent behavior in electrolytes that have specified chemical properties and will expand to include the quantification of kinetic factors during water-ion and ion-ion interactions. Modeling will incorporate the equation of state based on statistical associating fluids theory.
“The corrosion and scale research being performed by Brine Chemistry Solutions is good for the Gulf of Mexico,” said Glenn Shreffler, executive vice president, engineering at MATCOR, a cathodic protection company that specializes in providing customized corrosion engineering and cathodic protection systems to oil and gas and other industries.
“There are a literally hundreds of oil and gas production wells in the gulf but there’s not a lot of data about corrosion and scale in deepwater, extreme pressure and temperature environments,” Shreffler said. “That means this research has the potential to provide a great deal of information, including predictive models, that will help us help our customers enhance production and improve safety and reliability.”
The corrosion and scale research is part of a larger, $4.5 million project that was awarded to Brine Chemistry Solutions by the Research Partnership to Secure Energy for America.
