What the frack?

The term "Fracking" is short for 

• hydraulic fracturing
• fractional distillation
• funky fracktions
• fractal mathmatics

Fracking is significantly different from primary, secondary and tertiary oil recovery because only fracking uses

• water to crack rock formations
• vertical drilling
• fluids to extract petroleum
• production of petroleum

The first step of fracking is

• horizontal drilling
• vertical drilling
• use of water to crack rock formations
• pumping oil to the surface

What is used to crack the rock which contains the oil?

• fracking fluids under high pressure
• explosives
• horizontal drilling through the rock layers
• vertical drilling

What is injected into disposal wells during the fracking process?

• used fracking fluids
• old drill pipe
• mixed oil and water
• SOx,NOx and CO2

Why are disposal wells drilled deeper than the ground water levels?

• used fracking fluid is toxic
• oil and water don't mix
• oil is less dense than water
• used fracking fluid is flammable

In the Edpuzzle fracking example, about how deep was the well?

• almost 2 miles deep 
• about 20 miles deep
• .02 miles deep
• 200 miles deep

As the well is drilled, what is used to protect ground water from leaks?

• cement and steel casing
• ruberized coating 
• nothing - the well is WAY below the ground water
• horizontal drilling

After fracking, WHY does oil move into the well?  

• Oil in the rocks is under high pressure
• Oil is less dense than water
• because of gravity
• fracking magic
