Oilfield properties frequently have areas where soils contain concentrations of crude oil. These soils can be either hazardous wastes or designated wastes under regulatory guidelines. As a result, property owners and financial institutions face potential liabilities when oilfield properties are transferred to new operators, abandoned, or converted to other uses. Modern, well-designed soil bioremediation systems are cost-effective ways to treat soils that contain concentrations of crude oil, and these systems can eliminate an owner's subsequent liabilities. A modern on-site bioremediation system requires significantly less surface area, results in lower operating costs, and provides more effective, expeditious results than traditional land-farming practices. It also eliminates potential long-term liabilities and is typically more cost-effective than excavation and off-site disposal of oilfield soils. Case studies indicate that on-site bioremediation systems have reduced crude oil contamination in soil to levels acceptable to regulatory agencies in less than 20 weeks in some cases, less than ten weeks.
