Disinfection* of Oilfield Waters

Uncontrolled bacteria can cause problems in the oilfield, including reservoir souring, microbially induced corrosion (MIC), and formation plugging. Disinfecting surface water before hydraulic fracturing ensures a healthy well. De Nora Neptune containerized systems offer a solution for controlling oilfield bacteria without damaging frac iron or frac fluids.

Oilfield waters treated with ClorTec sodium hypochlorite generators see bacteria populations reductions of 99.999% or more, ensuring decontaminated water, wells, and equipment.

Oxidation of Produced Waters

Due to cost pressures from ever increasing volumes of produced water, scarce freshwater resources, and more stringent environmental regulations, oilfield operators are actively looking for ways to better manage their produced water resources.

De Nora’s containerized ClorTec® electrochlorination systems can help meeting produced water treatment challenges. Sodium hypochlorite can not only eliminate hydrogen sulfide, but it can also oxidize naturally occurring iron, which helps in the removal of both iron itself as well as total suspended solids from the water.

Oxidative treatment, coupled with settling tanks and filtration, can be used to produce a clean frac-ready brine that is also free of bacteria. Treated produced water is also readily used in injection wells for enhanced oil recovery or salt water disposal.

How De Nora Helps

De Nora's ClorTec® electrochlorination systems generate and deliver sodium hypochlorite at any point in the upstream and midstream water utilization cycle in various oilfield applications. As the safest and lowest cost oilfield water disinfection option on the market, the ClorTec system:

• Produces 0.8% sodium hypochlorite concentration
• Produces a mild pH solution
• Uses only water, salt, and electricity
• Costs only pennies per barrel treated
