The organization is very, very large. It's important to emphasize that -- as a relatively junior employee, it's easy to get lost. The place can be quite bureaucratic and is full of rules, regulations etc. -- keeping up with all the paperwork can be draining, especially when you're still expected to keep up with an ample workload. And about that workload -- it can be intense, especially for field personnel. The pay really isn't sufficient to cover the hours I put in, although there are many jobs within the organization which are better paid than mine. And finally, as a critique of the industry more than a problem with Schlumberger per se, at the end of the day you're little more than a technician. There are only so many iterations of the same problems, a pretty constant set of solutions and devices which Schlumberger sells to solve them, and once you've seen them all (or even just most of them) it gets pretty boring and pretty routine. Creative thinkers would be better served somewhere else.
