Tharmon..The product has proven test studies that show increased oil production. In East Texas I know for a fact of some wells that were treated with 50-55 gallons approximately 3 times in a year and production increases of 100-500% occured in some cases. It works by managing sludge and parrafin. There has been some testing of acid in various quantities on the pri wells that showed some promising signs, but I don't know if the petrozene is involved.
