The diversity of Canadian horizontal well applications illustrates the improved oil recovery potential of this technology. Canada has been a pioneer in IOR with horizontal wells since the late 1970s.
Improved oil recovery (IOR) horizontal well applications are increasing rapidly. Currently, about 5% of the over 7,500 horizontal wells worldwide involve IOR. As more horizontal wells are drilled, it is inevitable that IOR will be a significant proportion of these applications.
Most IOR with horizontal wells has been successful, both in terms of oil productivity and economics. In most cases, project cost has been reali...
