Well suspended after produced water spills into wetland northeast of Drayton Valley

The Alberta Energy Regulator has ordered an oil and gas company to suspend a well and associated infrastructure after a produced water spill northeast of Drayton Valley.

The AER says Obsidian Energy became aware of the spill at noon on May 29, and notified the AER that afternoon.

Eighty 80 cubic metres of produced water spilled but did not enter any bodies of water.

Produced water is water that’s a byproduct of oil and gas exploration and production. It’s high salt content and chemical contaminants can cause negative environmental impacts.

AER sent inspectors to the site and confirmed the produced water had spilled into a wetland, a tributary of the Pembina River about 40 kilometres northwest of Drayton Valley.

The AER’s order states that it found the spill was not contained and was greater than initially reported when staff visited the site.

Cleanup of the spill is underway. There is no reported effect on any residents or wildlife.

Obsidian is conducting detailed monitoring of soil, water, air, vegetation and wildlife.
