Hi Frank,
Thanks for the background on Rubin Baker, I didn't know that.
when you mentoned BJ services i remembered a cementing company who were always around on jobs i worked on.
they were https://www.bjservices.com/our-compa.../the-bj-legacy
and not connected to Baker Hughes.
The only direct involvement i have had with Baker Hughes was in writing a safety report on the use and implications of using ROVs when interfacing with assets. The guy was called David Bailey, apparently he wasn't the Royal photographer- David Bailey.
