The well, operated by ExxonMobil subsidiary XTO Energy Inc., had been leaking for several days
WILLISTON, N.D.—North Dakota oil regulators say a well that leaked oil, gas and brine for more than two days has been brought under control.
Oil and Gas Division spokeswoman Alison Ritter says the XTO Energy Inc. well in McKenzie County was under control, but had been leaking since at least October 16.
The North Dakota Department of Health says the incident resulted in the release of 650 barrels of oil and 520 barrels of brine. Brine is an unwanted byproduct of oil production and is many times saltier than sea water.
Ritter says inspectors are on site trying to figure out the extent and impact of an unknown amount of mist that moved off of the well location.
The well is about 4 miles northwest of Watford City and is operated by ExxonMobil subsidiary XTO Energy Inc.
