CAPS member MFBajanCajun elaborates on the bull case:

Schlumberger is miles ahead of its nearest competitors ... in a field that WILL, sooner or later, 'pop' again. (and again, and again, and again). Until a real game-changer comes along in the energy industry, oil is tightly interwoven into the fabric of life on planet earth as we know it. Enough has been said about our dependency on oil, do I really have to say more? Schlumberger helps oil majors to get oil out of the ground, and they do it more & better than anyone else.
