Areas of operation: Progress is the largest landholder in the Montney shale in northwestern Alberta and northeastern B.C. It is also active in Alberta's Deep Basin.
The Buyer: Petroliam Nasional Bhd, or Petronas, is wholly owned by the government of Malaysia. It has assets and interests in more than 30 countries and is heavily involved in the liquefied natural gas, or LNG, business.
The Offer: Progress announced in late June it had agreed to Petronas' $20.45-per-share takeover offer. A month later, the Malaysian state-owned company sweetened its offer to $22 per share in order to trump a rival bid, bringing the deal's total value to $6 billion.
The Premium: The sweetened offer is worth double what Progress shares traded at the day before the initial takeover deal was announced.
Partnership History: In mid-2011, Progress and Petronas formed a 50-50 partnership to jointly develop the some of the Canadian company's land in the north Montney. The two companies are also partnering on a liquefied natural gas terminal near Prince Rupert, B.C.
