The Toot Oilfield is an oilfield in the Pothohar Plateau of northern Pakistan. It is located approximately 135 km southwest of the capital city of Islamabad. The field was discovered in the early 1960s. Pakistan Petroleum and Pakistan Oilfields explored the field in 1961. In 1964 the first well was drilled. The commercial production started in 1967. There are about 60 million barrels of oil in place with 12%-15% of which is recoverable. At its peak during 1986, the field was producing approximately 2,400 barrel of oil per day.
In 2005, the Vancouver-based International Sovereign Energy signed a memorandum of understanding with the Oil and Gas Development Company Limited, Pakistan's national oil company, to develop the Toot field.
