Overview
Hudson's Bay Oil and Gas Company Limited was a Canadian non-integrated petroleum company that operated from 1926 until 1982. It originated as the Hudson's Bay Marland Oil Company, a joint venture between the Hudson's Bay Company and American oil entrepreneur Ernest Whitworth Marland. The venture was established to exploit petroleum and natural-gas possibilities on lands where the Hudson's Bay Company retained mineral rights after the transfer of Rupert's Land to Canada. The original partnership achieved little during its early exploration in the Rocky Mountain foothills. Financial difficulties at Marland Oil led to control passing to J. P. Morgan & Co. and subsequently to Continental Oil Company, known as Conoco. In 1929, Conoco reorganized the enterprise as Hudson's Bay Oil and Gas Company. The restructured company continued to face a long period of unsuccessful exploration, spending heavily without finding commercial production. A ten-year drilling agreement with Imperial Oil and joint activity in Turner Valley eventually helped establish a production base. The discovery of Leduc No. 1 in 1947 renewed interest in western Canadian exploration and encouraged Conoco to intensify its Canadian operations through HBOG. The Hudson's Bay Company's extensive mineral-right holdings gave the company access to large prospective areas in Alberta, Manitoba, and Saskatchewan. HBOG became profitable in 1956 and made a public offering in 1957, while the Hudson's Bay Company exercised its contractual right to acquire a 25 percent interest in 1952. During the 1950s and 1960s, HBOG developed into a major Canadian producer. It participated in the Trans-Canada Pipe Line project, operated or held interests in important oil and gas properties, and opened the Rangeland Pipeline in 1955. Its most important discovery came in 1962 at Kaybob South in Alberta. The field became one of Canada's largest gas accumulations, with reported sour-gas reserves of approximately 2.3 trillion cubic feet. HBOG also held interests in Zama Lake, Brazeau, and Sundre, and expanded its exploration activities internationally during the 1970s into Australia, Indonesia, and the North Sea. By the late 1970s and early 1980s, HBOG ranked among Canada's leading petroleum companies. In the early 1980s it was described as the country's eighth-largest oil producer, fifth-largest gas producer, and seventh-largest combined oil-and-gas producer. Its Calgary offices and distinctive oil-drop-shaped H logo represented the company's position as a substantial national energy enterprise. The company disappeared as an independent business during a major period of restructuring in the Canadian petroleum industry. Dome Petroleum, seeking to increase cash flow and strengthen its Canadian ownership profile in response to the federal National Energy Program, arranged to acquire Conoco's 52.9 percent interest in HBOG in 1981. Dome subsequently purchased the Hudson's Bay Company's remaining 10.1 percent interest for approximately $2.3 billion. The total transaction cost was about $4 billion, then the most expensive takeover in Canadian history. HBOG was amalgamated with Dome Petroleum on March 10, 1982. The acquisition contributed to Dome's severe debt problems, and its former HBOG assets later passed to Amoco Canada after Amoco acquired Dome in 1988. HBOG was deregistered in 1989.
History
The company's origins lay in the Hudson's Bay Company's retained mineral rights. Although the company had surrendered Rupert's Land to Canada in 1870, it retained significant land and mineral interests. Legal disputes over those rights were resolved in the early twentieth century, encouraging the company to consider petroleum development. In 1926, American oilman Ernest Whitworth Marland proposed a partnership to Hudson's Bay Company governor Charles Vincent Sale. Marland's company would receive a long-term option to lease Hudson's Bay lands for oil and gas development while paying royalties on production. Each party contributed $100,000 to establish the Hudson's Bay Marland Oil Company Limited. The venture controlled access to mineral rights covering millions of acres in Alberta, Manitoba, and Saskatchewan, but its initial drilling program in the Rocky Mountain foothills produced no commercial success. Marland's financial collapse resulted in the loss of control of Marland Oil and the associated Canadian venture to J. P. Morgan & Co. In 1929, both came under Continental Oil Company control. Continental incorporated the Hudson's Bay Oil and Gas Company on October 5, 1929, under a revised arrangement that preserved Hudson's Bay Company's option to acquire a quarter of the enterprise. Exploration from 1929 to 1933 cost approximately $1.9 million without a discovery, and the Keho No. 1 well was abandoned as a dry hole in 1934 after an exceptionally long drilling effort. A ten-year agreement signed with Imperial Oil in 1934 broadened the exploration effort. Imperial and HBOG jointly drilled in Turner Valley beginning in 1939, and by 1947 HBOG was receiving a substantial share of production. The Leduc discovery in 1947 transformed the outlook for western Canadian petroleum and prompted Conoco to renew active exploration through HBOG. The company's extensive land position meant that it could often pursue acreage near important discoveries. Hudson's Bay Company exercised its contractual right to purchase a 25 percent stake in HBOG in 1952. The company recorded its first profit in 1956, and Conoco sold a minority public stake in 1957. HBOG then expanded from a largely exploratory enterprise into a significant producer and infrastructure participant. It helped guarantee financing for the Trans-Canada Pipe Line and, with Amoco Canada, produced from the Pembina field. In 1955 it opened the Rangeland Pipeline, linking with Conoco's Glacier Pipeline in Montana. The 1962 Kaybob South discovery was the company's defining technical and commercial achievement. The Alberta field contained approximately 2.3 trillion cubic feet of reported sour-gas reserves and became Canada's largest gas field. HBOG also developed or held interests in Zama Lake, Brazeau, and Sundre. During the 1970s it broadened its international exploration program to Australia, Indonesia, and the North Sea. The company's Calgary headquarters moved from the Hudson's Bay Oil and Gas Building, opened in 1955, to Scotia Centre in 1976. Its stylized oil-drop H logo was introduced in 1967. The final phase of HBOG's history was shaped by Canadian energy policy and corporate finance. The federal National Energy Program, introduced in 1980, promoted Canadian ownership and energy self-sufficiency. Dome Petroleum, then heavily foreign-owned, created Dome Canada Limited and pursued HBOG to increase cash flow and strengthen its Canadian position. Dome first acquired a substantial position in Conoco and negotiated to exchange it for Conoco's 52.9 percent HBOG holding. It then agreed in November 1981 to buy the Hudson's Bay Company's 10.1 percent interest for about $2.3 billion. The total takeover cost approached $4 billion. Shareholders approved the transaction in January 1982, and HBOG was amalgamated with Dome on March 10. The enormous acquisition burden, combined with high interest rates, changes to tax rules, and difficult oil-market conditions, helped push Dome into a severe debt crisis. Dome was ultimately acquired by Amoco Canada in 1988. HBOG was deregistered on May 1, 1989, ending the legal existence of the company while its assets continued under successor ownership.

Products and positioning
A large, resource-oriented Canadian exploration and production company built around extensive mineral-right holdings, oil and natural-gas discoveries, and participation in national pipeline infrastructure.
Upstream petroleum
Crude oil production
HBOG explored for and produced crude oil in western Canada, including production associated with Turner Valley and the Pembina field. The company was non-integrated, focusing primarily on exploration, field development, and production rather than operating a complete refining and retail network.
Upstream petroleum · 1962
Natural gas and sour gas
Natural gas became one of HBOG's most important businesses. Its 1962 Kaybob South discovery created a major position in Alberta sour gas, supplemented by interests at Zama Lake, Brazeau, and Sundre. These assets helped make the company one of Canada's leading gas producers by the early 1980s.
Pipeline infrastructure · 1955
Rangeland Pipeline
Opened in 1955, the Rangeland Pipeline was a transportation asset connecting with Conoco's Glacier Pipeline in Montana. It supported the movement of petroleum from western Canadian production areas into broader regional infrastructure.
