Shell Tag?

I noticed that these 3 sets are tagged with "Shell", but I can't seem to figure out why, apart from the fact that they have an oil drum that's in Shell's colors?

#6381
#6673

Is there any additional relationship between these sets and Shell?  If not, should the Shell tag be removed?

I suspect that'll be why.
