One of the specific things that I was referring to are Dean-Stark extractions of water and oil from cores. There's nothing hugely complicated about that sort of service. They line up dozens of heaters, extractors, and cooling fluid lines and off to the races. Anybody could do the same work in their garage. If CLB is making 30% margin on that, then lots of unemployed folks should start setting up shops at home. I have no idea what side of their business they shoehorn that sort of service into. Sometimes the difference is a little grey and fuzzy.
