I don't think that Exxon Mobil are using any Bell 47s now, I think they switched to turbines in about 1970, but I stand to be corrected. Bell 412EPs are the type now, still almost the same as the G2 really and they are both Bells, I suppose.
I don't know what Exxon Mobile are using, are they a new company?
Please let me know what substance you are taking, I think I might like some.
