Cramer reviewed the entire oil patch production process.  From drillers to refiners.

Here are the picks:

Oil rig infrastructure (My Rig Maker Pick):
NOV  (NATL OILWELL VARCO)

Oil rig operators:
NBR  (NABORS INDS INC NEW)

The bottom line!:  I think you should buy NOV, NBR, RDC, and GSF!

The oil food chain:
