a: Fracking ~
b: bendy straw drilling
What: As noted, one of the key technological advices in this oil extraction process is the ability to drill sideways; that is horizontal drilling that starts from a vertical drill head and bends at the stratum where the oil occurs. A bendy straw is a good visualization of this process. There is a picture in the linked page as well as a discussion of fluid mechanics that may or may not be relevant to fracking.
