For what it's worth, your friend's data may be somewhat dated:
British Petroleum merged with Amoco (formerly Standard Oil of Indiana), in December 1998, becoming BPAmoco until 2000, when it was renamed BP.

I wholeheartedly agree with the suggestion to conserve what we have, although I seem to recall that our VP Dick would only consider see that to be a nice personal virtue and not a serious element of a viable energy policy.
