Petroplex International is not currently listed on a stock exchange as of August 2015, according to business news website Bloomberg.com. The company is involved in logistics and construction of oil refining and transportation facilities in the Louisiana area, as reported on the company website.
A stock connected to the term "Petroplex," as it refers to the oil-producing regions of Texas, was rumored to be likely to increase in value sharply by some analysts in August 2014, according to stock analysis website StockGumshoe.com. However, the stock in question was thought to most likely be Lynden Energy rather than Petroplex International. Lynden Energy is listed under LVLEF on stock exchanges.
