The latest acquisition is the first investment for both the companies, after signing the Memorandum of Understanding in December 2011.
The acquired assets are expected to contain about 978 billion cubic feet of proven and probable gas reserves, with production capacity of about 250 million cubic feet equivalent per day, which is equal to 15 million barrels of oil equivalent per annum.
The assets are situated near to Centrica assets in South and Central Alberta and in North East British Columbia.
The acquisition also comprised about one million acres of under-developed land, which is expected to have potential reserves.
