We installed a series of trenches with reclaimer pumps to suck the oil up and they ran for a decade. The oil ooze was sold to an asphalt paving company.
Just as we thought the pumps were reducing the oil content, a surge of oil moved on to the property from land across the street. Digging back in the records, we found the acreage once was once part of John D. Rockefeller's first turn of the century oil refineries.
