Another battery of field tanks at the huge Ashland Oil lease. In the 1960's cheap high sulphur content natural gas was shipped by pipeline from Texas to be injected into the oilfield for secondary recovery. Some of the sulphur combined with water and formed sulphuric acid which destroyed piping, tanks and other equipment. Many of the tanks and pipes rusted and the remains left have giant holes in them. The injection of this natural gas with its high sulphur content was a disaster. Another problem is that the underground tubing developed a radioactive level that is too high to be scrapped. It's unusual to see all of this equipment rusting away and to inspect a tank and find holes through it's sides and bottom.
