Louisiana – the capital of voodoo in the U.S. – has an aura of mystery to it, but fracking companies in the Pelican State can't have any mysteries in their hydraulic fracturing fluid.

On October 20, the Louisiana Department of Natural Resources (DNR) Office of Conservation announced that it was implementing a new regulation that requires drillers to obtain a work permit and disclose the fluids that they plan to utilize when engaging in hydraulic fracturing or "fracking" of wells in the area.

The new rules also require that the fracking mixtures utilized and the volume used be reported to either a public registry or the Office of Conservation, Rigzone reports.

State Commissioner of Conservation James Welsh stated that the new regulation provides for increased transparency and permits the office to gather more technical data than it could previously, the media outlet reports.

"With the intense development of the Haynesville Shale and in the interest of being protective of the environment, revising our rules provides substance and transparency," Welsh told the media outlet.

Fuelfix reports that activity has been decelerating in the Haynesville shale, which is the state's major shale formation. The number of rigs in the state has dropped by 13 percent this year, and Baker Hughes data indicates that no other major energy-producing states lost rigs during the period.
