Freeze protect fluid spill at Nuna pad
Caelus Natural Resources Alaska had a freeze protect fluid spill at the Nuna drill site, well NDST-2. The Alaska Department of Environmental Conservationís Division of Spill Prevention and Response said in a July 11 situation report that the spill was discovered June 18 and reported that day.
The release was initially described as 5 gallons of crude oil that had escaped the well cellar and an unknown amount of crude in ice within the well cellar.
On July 7, after the ice in the well cellar melted, DEC said Caelus reported removing 2,500 gallons of freeze protect fluid, an oil similar to mineral oil.
On July 10 Caelus increased the estimate to 2,900 gallons - the amount that had been removed from the well cellar and surrounding gravel pad.
DEC said it was coordinating with Caelus and the Alaska Oil and Gas Conservation Commission to investigate the cause of the release. The well is an oil and gas production well which was suspended at the time of the release.
DEC said Caelus continues to remove product from the well cellar and to remove contaminated gravels. The company will continue to delineate the extent of the release and remove product and contaminated gravel. DEC, Caelus and AOGCC will continue to search for the source of the release.
