Advantage Oil & Gas Ltd. is a Canadian oil and gas company based in Calgary, Alberta. The company owns and operates numerous properties located in Alberta, British Columbia and Saskatchewan, producing the equivalent of 35,000 barrels (5,600 m) of oil per day in late 2007.
In May 2006, the company, then structured as a royalty trust named Advantage Energy Income Fund, merged with another Calgary-based oil and gas trust, Ketch Resources.
The company claims its reserves to have a lifetime of 11.8 years at the current production rate, although it actively seeks to acquire new properties. In 2007, 65% of its production was natural gas, and 35% light oils and NGLs.
