Oasis Petroleum said crews have successfully plugged an oil well in North Dakota which had been spewing oil and saltwater for a number of days.
The Houston-based oil company said the well had been put under control after problems began at the weekend.
Regulators had seen a light sheen on the White Earth river, around 850feet from the well.
Since the incident happened 1,760 barrels of oil and 2,000 barrels of saltwater have been recovered.
