When the particle attractions are stronger, the molecular size of the particle is larger. This effects properties like boiling point. When the attractions are stronger the size of the molecule increases creating more viscosity. This means they'll be hard to take apart because there bonds are stronger. It will take more energy to break these stronger bonds so the boiling point is increased. When the particle attraction is lower so is the boiling point because it takes less energy to break the bond creating less viscosity.

Before the oil can come out of the ground it has to be found.Geologists look at surface rock and soil types to determine where the oil might be located. Modern oil geologists examine surface rocks and terrain, with the addition of satellite images or locate oil using Vibrator or Thumper trucks to cause vibrations in the earth which are listened to by geophones. The data is processed by computers into dimensional displays that are seismic lines.
When it is time to dig into the ground for the oil, the land has to be flat and cleared. After the well has been drilled, a measuring device is lowered into the hole and information is gathered about the properties of the earth such as density, type of rock present, and what fluids the rocks may contain.The drill used requires water, so there has to be a water source. A reserve pit is dug to put the rock and mud that come up with the drilling. Now they drill many hole to place the rig and support the main drill.
When they are ready to drill, they set the drill tip in the hole and begin drilling. They add and remove pieces of the drill as it goes deeper. When the drilling is over a cement pipe goes down the hole then allow the oil to flow. Then they build a cement well directing the oil into the well. The pump they place into the well that sucks out the oil.
