Trademark Fringement

I'm in Freetown, Sierra Leone, where a trip to the gas station put me in mind of a post from earlier this year in which I documented the hand painted branding efforts of Vietnamese marine diesel fuel dealers in Dong Hoi. A google search for "NP Petroleum" brings up the National Petroleum company of Trinidad and Tobago as well as a Canadian outfit called Northern Petroleum, neither of which share this BP-inspired logo. Could it stand for "Nigeria Petroleum," or was the B simply changed to an N on a whim? Perhaps these are the proprietor's initials.
