Chesapeake Energy Corp. is testing hydraulic-fracturing or fracking fluids composed solely of environmentally benign components in wells, according to Bloomberg News.
The Oklahoma-based company plans to develop a 100 percent green mixture of fluids, a company official said on Tuesday at a conference in Columbus, Ohio.
"It's not quite there yet," said Jody Jones, Chesapeake's manager of environmental and regulatory affairs.
The main concern is spending up to $6 million to drill a well and then run the risk with testing the new chemicals, Jones said.
The new chemicals would also reduce the threat from surface spills and reduce workers' exposures to potentially harmful chemicals.
Companies like Baker & Hughes and Halliburton have been working to develop more environmentally friendly chemicals, too.
