Learn “How Registered Biocides Protect Your Assets, Your People and Your Reservoir” by Watching the World Oil Frac Forum Webcast

September 1, 2020

Without biocidal treatment, your assets and equipment are at high risk for microbial contamination, resulting in significant safety concerns and economic challenges. Watch Lynn Yakoweshen, Global Business Manager, Stepan Oilfield Solutions, in the on-demand World Oil Hydraulic Fracturing Forum Webcast, “How Registered Biocides Protect Your Assets, Your People and Your Reservoir."

Yakoweshen will present various approaches that show how PETROCIDE® Registered Biocides are effective at reducing problematic oilfield microorganisms at varying developmental stages. Laboratory tests show Stepan’s PETROCIDE product line can eradicate bacteria in the free-floating (planktonic) and surface-attached (biofilm) life cycle stages. 

Located in Houston, Yakoweshen has been involved in oil and gas for nearly 20 years, transitioning from sales, to business development, to global business leader. She previously worked for companies in energy divisions at Canada Colors & Chemicals, PChem and Weatherford Engineered Chemistry.  She joined Stepan Company seven years ago, forming Stepan Oilfield Solutions, a strategic team of chemists, engineers and sales professionals who develop innovative solutions and take them to market. Yakoweshen earned her Bachelor of Science degree from the University of Alberta, and Master of Business Administration degree from Cornell University.

Answer: Even though oxidizers are inexpensive and are effective for providing an initial knockdown, they are consumed by the time they get pumped into the formation. As a result, the bacteria that get introduced into the process from the proppant, equipment or other additives remain untreated. The purpose of a biocide program is to have an active biocide downhole protecting you under conditions that are conducive for bacterial proliferation: friction reducers and other additives that act as food sources. Quaternary amines, which remain stable at bottomhole conditions, are therefore ideal for providing long term biocidal performance.

Answer: We have run more than 1,000 tests on our friction loop, including tests where we use biocides at field use dosages. We have not seen a measurable negative impact on FR performance in those tests. This was corroborated by an external consultant's test results. As for the foaming comment, we suggest using an antifoam on the surface.

Answer: Oxidizers and glutaraldehyde are not effective up to these temperatures. Surface active quats like ADBAC and DDAC are proven effective up to 125°C/257°F.
