I work for one of the 4 or 5 largest O&G Services companies out there. I can confirm that we've already (quietly) implemented across the board 15% budget reductions for 2015. Compared to most companies, our financials are actually in pretty good shape but still not great. I think the 15% reduction will be 25% - 30% by the end of the first quarter.
Some of the more experienced folks I've talked to have said there will be two different types of services companies as the next 6 months unfolds:
1) The handful of big boys (and there truly are only a few now) who will either roll the dice on long term growth and use this market dip as an opportunity to acquire the little guys for nickels on the dollar; or go through major RIF's, keep debt low and hunker down with a plan to jump back in when the market picks up. This second group could be the most dangerous to the economy, obviously, as they will lay off en masse, not hire and not spend on anything other than keeping the lights on.
2) The little guys, most of whom are in debt up to their eyeballs, will almost certainly go bankrupt or sell themselves to the big boys because they'll have no choice. They all banked on $70-90 oil and borrowed accordingly. Of course consistent, healthy prices of $60-$80 could keep some of the afloat.
I've been with non-O&G companies in other industries that went from the top of the world to practically non-existent and others who reduced workforce by 70% in a year, so nothing would be shocking to me regardless of the company. It's the new normal.
