Halliburton dishes

The giant energy company Halliburton says it will make public the secret ingredients for its hydrofracturing or “fracking” fluid cocktail.

The Associated Press reports the company also plans to release the ingredients to other states in which it performs the controversial hydrofracturing process.

Fracking forces these chemicals and huge amounts of water down drill holes to release natural gas or oil. Drilling companies have long maintained that specific information about the fluid was protected, and has not released it.

The company Range Resources was the first to announce it would release information about the formula.

The Halliburton action is not exactly magnanimous, WHYY’s Kerry Grens reported the EPA subpoenaed the company for the information a few days ago.
