Colossal Chore

Consider the volumes involved: At perhaps 3.5 million barrels per day, Canada is the world

At every stage, considerable volumes of waste need to be treated. Consider the sources of upstream oilfield waste. Seismic surveys, wellsite construction and drilling produce wastes ranging from bush cuttings to rock chips to drilling and fraccing fluids. Production wastes include salty byproduct water, gunk in tailings ponds, contaminants like carbon dioxide and hydrogen sulfide, and soil contaminated with sulfur. Once a plant needs to be decommissioned or a well shut in and abandoned, the producer creates more wastes that need to be carefully managed.
