Encana Caps Duvernay NatGas Well

A damaged wellhead near Fox Creek in the Duvernay formation that was venting natural gas and condensate was capped on Sunday, Encana Corp. said.

Spokesman Jay Averill said shortly after noon on on Sunday, "specialized teams on the ground with support from our emergency response center in Calgary safely brought Encana' damaged wellhead in the Duvernay under control and the flow of natural gas and condensate has been stopped."

The gas well, licensed to produce hydrogen sulfide (H2S2), had a blowout last Monday (Sept. 21) about 18 kilometers (11 miles) west of Fox Creek in the Kaybob North Field region (see Shale DailySept. 23). Monitoring data indicated low levels of H2S2 had been released, but they were beneath levels that would pose a health risk.

The cleanup of the site and an investigation is underway.

"We are fully committed to ensuring any related environmental impacts are effectively remediated," Averill said. "There is an environmental team on the ground assessing the area and developing a remediation plan. In addition, we are working to determine the cause of the incident in order to prevent a similar incident from happening in the future.
