Play Timeline

Roger Butler and In Situ Development

Dr. Roger Butler (1927-2005) was instrumental in making in situ bitumen recovery possible. Involved in the design of two industry-influencing methods—Cyclic Steam Stimulation (CSS), as Imperial Oil’s research manager, and later Steam-Assisted Gravity Drainage (SAGD) with Imperial and AOSTRA—Butler contributed to technology that has made Alberta’s oil sands a vital and competitive source of petroleum energy.

Shortly after his 1951 graduation from Imperial College in London, England, with a PhD in chemical engineering, Butler originally came to Canada and joined the faculty at Queen’s University in Ontario. Before joining Imperial Oil in 1955, he taught chemical engineering at Queen’s University in Ontario. Butler developed his pivotal SAGD technology at first as a theoretical concept after gaining mining experience at Cold Lake and in Saskatchewan. He patented his gravity drainage concept in 1969 and pursued the idea further after 1975 when he moved from Ontario to Calgary to lead heavy oil research for Imperial Oil.

In this role, Butler expanded his thinking about his theory and how to effectively extract bitumen too deep below the Earth’s surface to be recovered through surface mining. He began to mull the concept of replacing conventional vertical wells with horizontal wells to draw out steamed bitumen from far below ground level. The technology was finally tested in 1978 at a Cold Lake pilot project for Imperial Oil. This test was the first attempt at pairing a modern horizontal oil well with a vertical steam-injection well. At that time, however, Imperial Oil felt the system was not ideal for its reservoirs in the Clearwater Formation at Cold Lake and so stuck to CSS systems.

Several years later Butler took early retirement from Imperial and went to work at AOSTRA just as it was considering constructing the Underground Test Facility. He suggested testing SAGD at the proposed facility on the Athabasca deposit. The technology yielded good results when tested, and it demonstrated the effectiveness of gravity in recovering bitumen from deep underground deposits. Butler’s appointment to the University of Calgary’s Endowed Chair in Petroleum Engineering in 1983 allowed him to further research SAGD technology, which has been described as the single most important development in oil sands technology since Karl Clark’s work on hot water separation.

SAGD appeals to producers for several reasons, not the least of which is its lower operating costs. This factor helped smaller-scale projects join the major companies in the oil sands. A significant difference between SAGD and CSS is the time involved. SAGD does not require the one month wait time that CSS needs for the steam to completely infiltrate the deposit before attempting to pump the bitumen to the surface. The introduction of computer-controlled drilling rigs greatly improved the precision with which wells could be drilled, enabling parallel horizontal wells to be drilled within 5 m (16 ft.) of one another.

In 1996, Butler founded a petroleum research and consulting company, GravDrain Inc., whose chief client was the heavy oil industry. Until his passing in 2005, he served as president of the company.
