Kansas utility regulators are considering requiring oil and natural gas companies to disclose information about the chemicals they use in hydraulic fracturing, also called fracking.
An attorney for the Kansas Corporation Commission outlined these proposed new rules Monday for a joint legislative committee that reviews administrative regulations.
Fracking uses water under high pressure to crack open rock formations and release oil and natural gas.
The information would have to be listed on a KCC database or in an existing online industry database.
A new report from the Kansas Geological Survey shows oil production in Kansas last year was up over 2011, but natural gas production was down.
Officials with the survey report the nearly 44 million barrels of oil produced last year were the most since 1995. The oil had a value of $3.7 billion.
