Environmentalists and First Nations are raising concerns about a heavy oilfield in northeastern Alberta that may still be seeping water and bitumen years after the flow was first discovered. The field, owned by Canadian Natural Resources Ltd. (TSX:CNQ), was the subject of a major investigation by the province's energy regulator after a major "flow-to-surface event" in 2013. The Alberta Energy Regulator says a fifth, which first leaked in 2009, stills oozes small amounts of fresh bitumen. 'Bitumen is still coming to the surface'Fraser Thompson of the environmental law firm Ecojustice said it's disturbing the leakage may be ongoing. In June 2013, the Alberta Energy Regulator reported a leak in CNRL's Primrose field near Cold Lake, Alta.
