Background: 1925–92
The origins of Talisman energy traces to the Supertest Petroleum Corporation, which was founded in 1923 and headquartered in London, Ontario.
In 1953, British Petroleum Company (BP) entered the Canadian market through the purchase of a minority stake in Calgary-based Triad Oil Company. In the early 1950s, the power struggle between oil companies and host governments in Middle East started, which hampered operations of British Petroleum in the region, and prompted it to diversify its operations beyond the heavily Middle East dependent oil production. The Canadian holding company of British Petroleum was renamed BP Canada in 1969; and in 1971, it acquired 97.8% stake of Supertest.
Subsequently, Supertest was renamed to BP Canada Ltd, and other Canadian interests of British Petroleum were amalgamated to the new company. BP retail operations disappeared from Canada in the early 1980s, when in 1982, BP Canada divested its downstream assets to Petro-Canada, which was at the time owned by the Government of Canada.
1992–2011
In 1992, British Petroleum sold off its 57% stake in BP Canada Ltd to the public. BP Canada was later renamed to Talisman Energy Inc. and one of Canada's largest independent oil and gas company was founded. After the split from British Petroleum, Talisman Energy sold off its money losing mining operations and focused on its large natural gas holdings in British Columbia, Canada.
Its subsidiary Fortuna Petroleum, became one of the first international oil companies to do business with Cuba. A year later in 1993, Talisman Energy bought Encor Inc from BCE, doubling in size and becoming one of Canada's largest petroleum companies. Talisman Energy acquired Bow Valley Energy from British Gas PLC in 1994, gaining more assets in Canada and an important presence in the North Sea and Southeast Asia. In 1995, it pulled out of Cuba to focus on these areas.
In 1997, Talisman Energy launched a takeover bid of Wascana Energy, a former crown corporation of the Saskatchewan government. It got into a bidding war over Wascana with Canadian Occidental Petroleum (later, Nexen), and failed in its attempt. It continued its aggressive expansion, investing in the North Sea and Indonesia; and in 1997, bought the smaller Pembina Resources.
In 1999, Talisman Energy acquired Rigel Energy. Since then, Talisman has expanded its operation in Southeast Asia and in the North Sea, with a brief exploration operations in South Eastern Trinidad & Tobago.
On May 30, 2007, the company announced the retirement of its longtime President & CEO, James Buckee. John Manzoni, formerly of BP, was named as his successor, effective September 1, 2007.[6]
In January 2008, Talisman agreed to buy RSX Energy Inc, an oil and gas company based in Calgary, Alberta focused on exploration and development in Western Canada. Formed in 1997 as Royal Sovereign Exploration Inc. it changed its name to RSX Energy in 2002.[7]
2012
In July 2012, Talisman Energy sold part of its interests in Britain to focus on higher-growth shale gas projects in North America and Southeast Asia. A joint venture with China Petroleum & Chemical Corporation Limited (or Sinopec) was announced, that saw Talisman sell 49% of its Aberdeen, Scotland-based North Sea business to Sinopec for US$1.5 billion.[8][9]
On September 10, 2012, the company announced that John Manzoni had agreed to step down as president and CEO, effective immediately, and would be replaced by board member Hal Kvisle. Kvisle had been on Talisman's board of directors since 2010 and was previously CEO of Canadian pipeline builder TransCanada Corp. between 2001 and 2010.[10] The news surprised market analysts and fueled speculation that Talisman was then a greater potential takeover target, similar to that of industry peer Nexen Inc. when it agreed to a $15.1 billion acquisition made by China National Offshore Oil Co. two months earlier. However, Kvisle stressed that he and the board would be focused on making Talisman a "sustainable long-term, successful Canadian company" rather than putting it up for sale.[11]
2013
In October 2013, activist investor Carl Icahn acquired around 61 million shares in the company and announced he would be seeking a place on the board. His acquisition prompted the firm's share price to rocket by 16% before ultimately plummeting 60% over the course of 2014 before Icahn divested.[12][13]
Acquisition by Repsol 2014-2015
Following months of speculation and negotiations, Spanish energy company Repsol tendered an offer to buy Talisman in early December 2014 for US$8 per share.[14][15] Including debt obligations of US$5 billion, the deal was worth US$13.1 billion.[16] On February 19, 2015, Talisman shareholders approved the acquisition offer from Repsol with 99 percent of shareholders in each class voting in favor of the deal.[2]
In January 2016, Repsol announced that the legal name of Talisman would be changed to Repsol Oil & Gas Canada Inc. effective January 1, 2016.[3]
