The reasons behind divestitures are clear: They are typically pursued to generate cash so that companies can invest in more promising parts of the hydrocarbon value chain, reduce their exposure to a particular part of the value chain, or exit areas of activity where they no longer have a competitive advantage. As a result, several peripheral industries—such as independent refiners, petrochemicals producers, pipeline operators and oil field services companies—have grown into major industries in their own right.
Margins across the value chain have been a key driver of this development. The very real threat of oil costing $10 a barrel in the late 1990s was a key driver of the supermajors’ strategy to drive down cost by exiting non-core activities in exploration and production, which preceded the snowballing growth of the oil field services industry. Similarly, since the end of the Golden Age of Refining in 2007, the oil majors have accelerated divestments in refining.
Where oil majors have been big sellers of assets that no longer fit their strategies, a wide range of buyers have apparently found those assets to be an excellent fit with their own strategies. Not surprisingly, Asian national oil companies have been amassing upstream assets to secure access to resources; but they have acquired downstream assets as well. For example, PetroChina has been pursuing deals in areas as diverse as Scotland and Latin America. Even airlines have entered the game, as seen with Delta’s 2012 acquisition of the Trainer refinery located outside Philadelphia.
