Energy Services

Our Energy Services division provides on-site, technology-driven solutions to the global natural gas, petroleum and petrochemical industries. In addition to recovery, production and process enhancements, we also deliver a full range of water treatment offerings to refineries and petrochemical plants.

The division is divided into a Downstream refinery and petrochemical processing service business, and an Upstream group composed of our Oilfield Chemicals and Adomite business.

Our upstream process applications improve oil and gas recovery and production, extend production equipment life and decrease operating costs through services including scale, paraffin and corrosion control, oil and water separation, and gas hydrate management solutions. Our downstream process applications increase refinery and petrochemical plant efficiency and the useful life of customer assets, while improving refined and petrochemical product quality and yields.


TIORCO is a joint venture of Nalco and Stepan Company to globally market custom-engineered chemical solutions that increase production of crude oil and gas from existing fields. The company integrates enhanced oil recovery (EOR) processes by leveraging Nalco's extensive reach in global upstream energy markets, TIORCO's 30 years of experience in EOR polymer and reservoir expertise, and Stepan's global surfactant technology and manufacturing capabilities. Customers receive the first unified approach to the EOR market – identifying, evaluating and implementing solutions that optimize oil recovery. TIORCO markets Nalco's proprietary BrightWater®—Reservoir Sweep Efficiency Technology, which was jointly developed with major oil companies.

Nalco FabTechequipment and services are utilized worldwide to optimize oil and gas recovery from drilling to production, including primary, secondary and tertiary recovery processes.
