Transcript snippet:
Geologists have known for years that a substantial amount of oil/gas are trapped in deep shale formation. These shale reservoirs were created tens of millions years ago. Around the world today, with modern horizontal drilling technologies and hydraulic fracturing, the oil/gas in the shale reservoirs can be safely and efficiently produced, gathered and distributed to customers.

Let's take a look at the drilling and completion process of a typical oil/gas well...
