Alberta Energy Regulator

One of the country's largest oilsands companies is facing federal charges in the death of 31 great blue herons at one of its mine sites in northern Alberta more than two years ago.

Geothermal energy potential from abandoned oil and gas wells could solve many problems and help the environment.

Oilsands giant Suncor Energy says it is mystified by the discovery Sunday of dead and dying birds at a nearly complete northern Alberta mine that hasn't produced its first official barrel of oil yet.

Where some see only a jumble of rusted pipes and black tanks jutting from a weed-infested yard in a prairie grain field, Tyler Visscher sees opportunity.

The Alberta Energy Regulator has laid five charges against Nexen Energy for a pipeline spill two years ago that was one of the largest in provincial history.

The conventional oil and gas industry is leaving a massive mess in Alberta. Regan Boychuk traces how it happened and shows how industry - not taxpayers - should be made to pay.

Alberta's oilsands could be heading for another showdown over tailings ponds after an independent assessment found that the cleanup plans of six major operators don't meet new rules.

Murphy Oil has been fined $172,500 after the Alberta Energy Regulator concluded the Arkansas−based company did not maintain a pipeline that leaked oil for 45 days before it was discovered.

According to the regulator, Lexin has failed to comply with multiple orders and doesn't have enough staff to manage its more than 1,600 sites.

A researcher says the agency that monitors Alberta's energy industry has underestimated the impact of tens of thousands of spills going back decades.

In the past three years, human errors — which covers everything from failing to follow procedures to using equipment improperly — has caused an average of 20 pipeline leaks per year.

Reading Andrew Nikiforuk's Slick Water will make you sadder and wiser with an understanding of how governments and Big Oil and Gas have sung from the same hymn book, writes Warren Bell.

Surface water collected near four fissures in the ground continues to show an oily sheen.

The pipeline leak has now damaged roughly three hectares of remote land in north-central Alberta.
