Diana’s father works in Houston, Texas, as a geologist in the oil and gas industry. He identifies locations where hydraulic fracturing, or fracking, might produce fuel resources.

How does fracking work?

• Pressurized fluids are used to break up layers of shale rock.
  
  They force out the natural gas trapped there, which is then collected.

• 
  Pressurized fluids are inserted into different kinds of rock.
  
  They force out the groundwater, and the fossil fuels are extracted from the groundwater.

• Pressurized fluids are inserted into deep oil wells to get the remaining oil.

• Pressurized fluids are inserted into known gas fields to locate the
  gases.
  
  The gases mix with the liquid before they are extracted.
