OPAB was an initiative of the Swedish government and Swedish private enterprises to harness some of the vast potential offered by a growing energy market. The state’s 50 per cent ownership stake confirmed that OPAB’s mission to find and produce oil and gas in Sweden was in the national interest. In 1973, as the first energy crisis crippled economic growth, the quest for hydrocarbons beyond Sweden became the mission of Petroswede, another private-public partnership. In 1979, the state-owned company Svenska Petroleum acquired parts of Petroswede and launched a new company named Svenska Petroleum Exploration. Svenska would later enter into an agreement with OPAB to operate all of its fields and take over staff and premises.
