Assessment of Extend and Estimate of Quantity of petroleum Leakage in underground layers of Abadan Refinery Area

Awareness of petroleum leakage in oil refineries is a vital issue in environmental investigation of water and soil pollution. During war between Iran and Iraq, leakage of enormous oil and its refined products from storage tanks, pipe lines, and refinery units of Abadan refinery to surrounding environment had occurred. Also, leakage of petroleum and its products during the existence of Abadan refinery to surrounding environment had led to conduct this research for determination of extension and quantity of oil pollution of underground layers of Abadan refinery. Location of twenty boreholes was investigated by considering petroleum leakage to surrounding area during and after war. Geological underground layers of Abadan refinery was determined from coring during drilling of the boreholes. Oil saturation, porosity and density of cores from underground layers were measured. Finally the quantity of existing petroleum in underground layers of Abadan refinery was estimated.
