I cannot see where BP has added much value to anything it has touched in more recent decades.
Purchasing Arco and selling off Prudhoe Bay. Buying Amoco and executing Macondo. Buying BHP's US assets and ?
Their historical emphasis has been in 3rd world countries where others fear to tread.
When I worked the North Sea in the 80s, I recall the one jewel in its crown was the Forties field, which others characterized as "God's gift to BP"
