Ive been in the Oil Patch for around 7 years now, working all over the world, but not a Rotary Pilot, just as one of your pax who happens to fly planks for fun. I have to say that some of the replies here made me smile. The ONLY places where the Oil companies (big/small/stateowned) pay any real regard to safety or environmental issues is where Government Legislation is in place to ensure it is there AND it is enforced either by inspectors or lawsuits.
cpt has it about right, the $£€ rules.

And another thing...the 'we care for the environment' oil/gas company ads just make me laugh
