The Coal Oil Point seep field offshore from Santa Barbara, California is a petroleum seep area of about three square kilometers, and releases about 40 tons per day of methane and about 19 tons of reactive organic gas (ethane, propane, butane and higher hydrocarbons), about twice the hydrocarbon air pollution released by all the cars and trucks in the county in 1990.[1] The liquid petroleum produces a slick that is many kilometers long and when degraded by evaporation and weathering, produces tar balls which wash up on the beaches for miles around.[2] ? This seep also releases on the order of 100 to 150 barrels of liquid petroleum per day. The field produces about 9 cubic meters of natural gas per barrel of petroleum.[2]
