PennEnergy reports that the number of rigs in this country has soared: 70 new rigs.

With various operators drilling the Bakken Shale, North Dakota added 14 rigs this week. An increase of 43 over the year, there are currently 175 rigs drilling in North Dakota – all of which are searching for oil. 

As you can see, the story is old. There are not 192 rigs drilling in North Dakota. It's possible they are not including the rigs that are drilling salt water disposal wells.
