Halliburton is having an index of the hydraulic fracturing chemicals they use assessed by a third party. Then they plan to release it for industry use.
The index addresses the ability of chemicals to be health, physical, and environment hazards.
Concerns related to heath include chemical toxicity and whether the chemicals are carcinogens and mutagens as well as if they affect reproduction and organs. Another health concern is whether the chemicals are corrosive or irritant substances.
Physical hazards relate to chemical properties such as explosiveness, flammability, oxidization, and corrosiveness.
Environment hazards include whether the chemicals produce acute-chronic aquatic toxicity, hazardous air pollution, and water pollution, as well as if the chemicals bioaccumulate, biodegrade, and are sustainable.
The index expresses the constituent concentration and health, safety, and environmental effect as a numerical aggregated score, Hyden said. He noted that the aggregated score allows companies to select chemical formulations that have the lowest score for their application.
