This is a nice article, from The Houston Chronicle for newbies (and maybe also for some us older folks, LOL). I'm sure the article will eventually disappear or end up behind a pay wall. This was published back on January 18, 2014. Archived.

Highly specialized mobile rigs are literally walking over the oil patch's collection of aging equipment - tamping down sales and profits in a burst of efficiency that's making some drillers victims of their own success.

But the market is getting tighter for drillers large and small, as producers embrace walking rigs - so-called for the massive mechanical feet that let them move among well sites - and other technologies that let them drill more wells and harvest more oil while spending less on oil field services.
Baker Hughes recently reported a 9 percent rise in the number of wells the average U.S. land drilling rig produced in the fourth quarter (2013), compared with the same period a year ago (2012).
