Canadian Natural Resources calls seepage a routine well failure

Canadian Natural Resources (CNQ) says the release of ~170 barrels of oil underground last week at a troubled production site in Alberta was a routine well failure and questions the chief regulator's decision to issue an incident report on it.

"There's no spill," CNQ says. "Casing failures do happen, and they're generally not reported as spills," but the Alberta Energy Regulator says there's no error in reporting the incident and an investigation is under way.

The Primrose site has suffered a series of unexplained subterranean leaks of thousands of barrels of oil dating back to May; unlike with this latest seepage at an active well, the earlier leaks involved abandoned well bores.
