Chemistry, like any other science, is important and what we should know for our daily life since chemistry makes us aware of the composition of the bodies that surround us, from a delicious fruit to a lifeless body such as it is in a mineral.

That is why this work will talk about the great importance of knowing about organic chemistry in one's work as a petroleum engineer in working life, as well as some experiences of some service engineers who wanted to share a little of their experience about knowing about organic chemistry.

In addition, this topic was taken to do this research because many students who are in the petroleum engineering career do not know about the great importance of taking this subject and they even ask themselves, what use is organic chemistry for us, if we are not going to use it? occupy? And the truth is that it is very important to know organic chemistry since, as we know, oil is composed or originated as you want to take it from the remains of many organic living beings that inhabited the planet earth millions of years ago, which reached their stage of death and they were deposited on the sea bed or on the surface, which had to die a large number of beings in order to form the oil that we know today.

 The beginning of all science that exists on this planet has been initiated mainly by the desire and great curiosity of the human being himself throughout his evolution.

With this curiosity, over time, they began to wonder what all the bodies in this world were composed of and thus they continued to investigate until the science of general chemistry was established.

The term "organic chemistry" was introduced in 1807 by Jöns Jacob Berzelius, to study compounds derived from natural resources.

In 1928, Wöhler observed when evaporating a solution of ammonium cyanate, the formation of large colorless crystals, which did not belong to ammonium cyanate.
The analysis of the same determined that it was urea.
The transformation observed by Wöhler converts an inorganic compound, ammonium cyanate, into an organic compound, urea, isolated from the urine of animals. This experiment was the confirmation that organic compounds can also be synthesized in the laboratory.
