​

Answer 1

X -  NATURAL GAS

Y - OIL

Z - WATER

• Oil well is boring on the surface of the earth to extract oils like petroleum or hydro carbonates.
• Some natural gases are also released in this process of extraction.
• In an oil well the topmost layer is of natural gases that are released during the process.
• Natural gases are followed by the layer of oil that is to be extracted.
• Then comes the layer of water that settles below the layer of gas and oil as both of these are lighter than water.
