De Nora’s product and industry expert, Andrew Boal, has a PhD in organic chemistry, having spent the earlier part of his career at Sandia National Labs and NASA doing research in nanotechnology and looking for life on other planets before joining the water industry. So, you may be wondering why he’s uniquely qualified to advise our Oil & Gas customers on how to best treat oilfield water at various stages of the production process. Today, his scientific mind is being applied to developing novel approaches to Oil & Gas water treatment, particularly for midstream companies and produced water recycling opportunities. As Andrew would say, “Think of produced water as a valuable resource, not an operational waste product.”

De Nora’s focus for the Oil & Gas industry has always been on disinfecting freshwater used in hydraulic fracturing; however, there has recently been increasing demand for midstream water management, because of the scarcity—and value—of fresh water. Since this is one of the more complex areas of water treatment, De Nora relies on experts like Andrew to address these challenges. “The makeup of this water is very complicated—much more so than at a municipal water treatment plant or cooling tower.” He further explains, “With hydraulic fracturing, you get 9-10 barrels of produced water for every barrel of oil, and that produced water needs to be disposed of elsewhere.” It is estimated that in the U.S. onshore environment, up to 20 billion barrels of water are produced every year, along with hydrocarbons. This water is injected into either producing wells for enhanced oil recovery or into saltwater disposal wells. Pure volume is just one of the reasons that the demand for recycling has increased exponentially.

Bacteria in Oilfield Waters and Why They Should Be Controlled

Oilfield bacteria are present everywhere water can be found in the hydrocarbon production process. Unchecked bacteria populations can result in operational issues through the upstream and midstream production environment. Starting at the producing formation itself, bacteria introduced into the formation during drilling, completion, or flooding can result in the plugging of the formation as well as the wellbore.
