Stress

Life used to be so much simpler for your friendly neighborhood oil tycoon. Back in the good ol' days (before social networks and viral videos), oil companies were free to pillage, pilfer, plunder, and otherwise pickaxe the face of the Earth without much fear or consequence. 

America and the rest of the world developed an addiction to low oil prices, and everyone was willing to turn a blind eye to potential hazards of drilling nonstop into the planet to harvest its resources.

Now, thanks in large part to Joe Twitter and Jane Hashtag, even the smallest fracking-related earthquake in West Virginia will be thrust into the public eye. Suddenly you're expected to research and deal with the problem. You'll have to take out an ad campaign to tell everyone how sorry you are. 

And don't forget all those lawsuits from families whose drinking water may or may not contain ignitable levels of gas, thanks to seepage from fracking wells.

All of that means one thing: losing money. And as everyone knows, there's nothing more stressful to an oil tycoon than losing money.
