Freestone Resources, Inc. announced it commenced sales of Petrozene through its majority-owned venture, Freestone Dynamis Energy Products, LLC (FDEP). FDEP also entered into its first sales agreement to provide Petrozene to oil and gas producers and regional transport companies in west Texas that suffer from production and transport-related issues due to paraffin and asphaltene buildup. Over time, paraffin and asphaltenes can cause reduced oil flow, as well as tank bottom sludge-related problems.
