Company investigates pipeline explosion that lights up sky in northern Alberta
Pengrowth Energy Corp. says it doesn't know what caused a pipeline explosion in Alberta on New Year's Day.
The explosion lit up the dark sky in northeastern Alberta.
Pengrowth says the explosion and fire happened on a line that carries condensed liquid gas from oilfields to a production facility at Judy Creek, which is near Swan Hills.
Pengrowth spokesman Wassem Khalil says it was in a remote location where there were no nearby homes or public buildings.
Mr. Khalil says no one was injured.
Mr. Khalil says the line has been depressurized and only small amounts of remaining gas in the line are still burning.
The company hopes to have the line operating again in five to 10 days.
