OFS3 turn to be a waste of time like the other classes. Only to show Exxon, Shell and other big oil companies that schlumberger cares and educate their Eng/tech (slaves) and keep them up to date with what so called new technology and new structure vision. Only lies.
Shell/chevron/Exxon... if you want to visit a location/shop/rig.. don't announce it, surprise the mother f***ers and you will find out the truth. You pay big money you deserve the truth.
