Drilling Process
Place the drill bit, collar, and drill pipe in the hole.
Attach the kelly and turntable and begin drilling.
As drilling progresses, circulate mud through the pipe and out of the bit to float the rock cuttings out of the hole.
Add new sections (joints) of drill pipes as the hole gets deeper.
Remove (trip out) the drill pipe, collar and bit when the preset depth (anywhere from a few hundred to a couple thousand feet) is reached.

Horizontal Drilling and Hydraulic Fracturing
• Increased technology allows us to retrieve “tight” formations.
• The drilling process is similar, except for a specialized bit that allows for horizontal drilling.
• If oil and gas are trapped, fracturing may be used to allow liquids to flow.
