Petroleum Engineering, Its Importance And Its Branches

Market | 2021-01-19 14:52:34.0 | By Melsham Mishra

Petroleum Engineering is one of the two most leading engineering majors in the world on the basis of income. To flourish a country towards development, Petroleum Engineers are one of the most essential engineers, especially in oil and gas producing countries like the USA. The famous saying 'Money Attracts Money' is truly valid in the oil and gas industry as it requires a huge investment, around millions of dollars, to operate it and if operated successfully a huge amount of profit can be gained from it. In oil and gas, the high investment is due to the various sophisticated techniques involved to carry out its operations.

Today, there are many countries in the world operating oil and gas businesses. Some of these countries are leading the oil and gas industry. Today, the USA is the world's largest producer of oil and gas in the world. It produces around 17 million barrels per day on average accounting for 18% of the cumulative world oil production. After the USA, Saudi Arabia and Russia acquire the second and third positions respectively in most oil-producing countries. Moreover, Saudi Arabia acquires the first position in the world's largest oil exporter in addition to the world's largest reserves of oil and gas. Likewise, the title of the world's largest oil exporter goes to China.

In small scale oil and gas companies ?Generalists? control all the aspects of the Petroleum spectrum. While the large scale oil and gas companies require the division of work and thus, division of Petroleum Engineers into different categories as per their function. Here are the main divisions of Petroleum Engineers in huge oil and gas industries.

What Is The Importance of Petroleum Engineering


Ever ending demand of energy

For carrying out the developments to the next level, there will always be the ever ending demand for energy. Automobiles, aircraft like airplanes, helicopters all require the natural energy, fuel, to operate. The application of petroleum is beyond the operation of automobiles and aircraft. One barrel of oil is equal to 42 Gallons and out of 42 Gallons, only 19.8% produces gasoline.

The rest is used in the manufacturing of a variety of other products like Car Battery Cases, Dyes, Shampoo, Toothpaste, Detergents, Antiseptics, Soap, etc.

Petroleum field is the field of innovation

In the Petroleum Engineering field, the involvement of different techniques and equipment and the innovation of different techniques to optimize the production causes it to be one of the outstanding unique fields to put your hands on. In the oil and gas industry, there needs to be a development of techniques depending on various unseen situations. This requires creativity and gives an opportunity for the Petroleum Engineers to stand unique among all the engineers.


Types Of Petroleum Engineering


1.Reservoir Engineers

Reservoir Engineers estimate the total reserves in the reservoir and also determine where the reservoir is located. Reservoir Engineers are the ones who develop the model of the reservoirs using various softwares like CMG software to have a better understanding and visualization of the reservoir underneath. Moreover, Reservoir Engineers also determine different fluid properties when the fluids move from reservoir to wellbore, wellbore to surface and surface to the facilities. The changes in the oil properties and gas properties during its movement from the reservoir to wellbore, wellbore to surface and surface to facilities play a huge role in the amount of oil and gas produced hence, also determines the profit.


2.Production Engineers



Production engineers come into play after the completion of the wells. They are responsible for production forecasts and selecting the production intervals in the reservoir. Their work also expands to the perforations, controlling sand and the bottom hole controlling. Moreover, they are responsible for designing the equipment that will allow the well to produce the most.


3.Completion Engineers



Completion engineers work on completing the well in the most effective way that will ensure the secured production of oil and gas.The process of completing the well is the same for the offshore and onshore wells. Once the drilling of the well is done, they perform the wellbore clean up work. They ensure the smooth, shortest (time) budget effective flow of the fluids to the surface. They analyze and recommend the effective ways in solving the wellbore problems.


4.Drilling Engineers



Drilling Engineers are responsible for the drilling techniques used to drill the well. The size, grade, weight and type of the casing, type of cement and the tubing are controlled by the drilling engineers. Besides drilling techniques, drilling engineers need to have the knowledge of the nature of the penetrating rocks and temperature underneath, which decides the type of drill bits to use and also the compressive stresses exerted on the rock.


5.Facilities Engineers



Once the well starts producing the job of Facilities Engineer comes into play. Facilities engineers work hand in hand with other engineers like Production Engineers. They work on different techniques to refine the product as best possible to optimize the profit. In addition, they are also responsible for the proper management to meet the financial as well as production targets.


6.Geoscientists - Petrophysical Engineer

Petrophysical Engineers are responsible for testing and analyzing the core samples to estimate the presence of oil. They also analyze the other properties of the rocks to have a better understanding of what's underneath. They also perform the estimation of the volume of petroleum underground. Moreover, they use sophisticated techniques to develop the structure of the formations below.
