Fracking Process and Challenges

The video tutorial explains the significance of shale formations in the U.S. as sources of natural gas and oil. It highlights the challenges of drilling these formations and how fracking technology has made it feasible, particularly in North Dakota's Bakken formation. The fracking process involves drilling deep wells, using cement and steel casings to prevent leaks, and employing high-pressure fluid to fracture rocks and release oil. The environmental impact of fracking, including the handling of toxic materials, is discussed, along with the expected increase in the number of wells in the future.

What is the primary challenge historically associated with drilling shale formations?

• Difficulty in accessing the formations

• Environmental regulations

• High cost of drilling

• Lack of technology

In which year did fracking begin in North Dakota's Bakken formation?

• 2015

• 2010

• 2006

• 2000

What is the purpose of inserting cement and steel casing in the well?

• To enhance drilling speed

• To prevent leaks into groundwater

• To reduce drilling costs

• To increase oil flow

Why does the well follow the sandstone layer during drilling?

• Shale oil collects in the sandstone layer

• Sandstone contains more natural gas

• Sandstone is more stable

• Sandstone is easier to drill

What role do plastic balls play in the fracking process?

• They increase oil production

• They seal the well

• They open sleeves in the pipe

• They help in drilling the well

How many times was the rock fracked in the Iverson well over three days?

• 15 times

• 29 times

• 45 times

• 60 times

What happens to the used fluid after fracking?

• It is released into rivers

• It is stored on-site

• Some is recycled, the rest is disposed of in wells

• It is all recycled

What is the projected increase in the number of wells in North Dakota?

• From 8,000 to 20,000

• From 8,000 to 100,000

• From 8,000 to 50,000

• From 8,000 to 30,000
