OIL AND GAS 1.1B INTRODUCTION (DIFFERENCE BETWEEN OIL AND GAS)

DIFFERENCES AND SIMILARITIES BETWEEN OIL AND GAS.

Oil and gas are similar in the following respects:

  1. Both are fossil fuels derived from petroleum (a hydro carbon formed from the decomposition of sea organisms millions of years ago).
  2. Both are (non-renewable) forms of energy with varying uses like transportation, heating, power and so on.
  3. Both are greenhouse gases[1].

The differences between crude oil and natural gas includes:

  1. When compared to oil, gas is more difficult to transport and store. In practice, highly sophisticated machineries and specialized pipelines are utilized in storing, transportation and liquefaction[2] of gas.
  2. There is a higher demand for crude oil because of its broad range of uses like manufacturing of plastic, rubber, cosmetics, and so on.
  3. When compared to oil, natural gas is cheaper and less harmful to the environment as it burns brighter, cleaner and hotter. Natural gas produces about 30 percent less Co2 than crude oil and 45% less Co2 than coal.
  4. Unlike gas, oil contains more complex hydrocarbons like cycloalkanes, asphaltene, and so on.
  5. Oil is liquid at room temperature while Gas is an aeriform mixture. Gas can be associated with oil or found alone (Section 362 PIB (on the definition of natural gas)). It can however be liquefied.
  6. Oil has a high density with low rate of diffusion while gas is of a low density and diffuses quickly. This explains the difficulty in trapping and transporting gas. Initially it was flared off until recently where new techniques like liquefaction are used to trap as much gas as possible.
