‘Generalists’ oversee all parts of the Petroleum spectrum in small size oil and gas enterprises. While large-scale energy industry firms require the division of work, and hence the split of Petroleum Engineers into distinct categories based on their function, smaller-scale oil and gas companies do not. The following are the major divisions of Petroleum Engineers in the vast oil and gas sectors.

What is the importance of Petroleum Engineering

There will always be an ever-increasing demand for energy to carry innovations to the next level. Automobiles, airplanes, and helicopters all require natural energy, or gasoline, to function. Petroleum is used for more than just driving cars and flying planes. One barrel of oil is 42 gallons, yet only 19.8 percent of 42 gallons create gasoline.

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

Energy consumption – Energy usage has been increasing constantly since the industrial revolution because of the advancement of technology. Today, due to the ever-increasing population and growing economy, it seems that we have a never-ending need for energy. This explains why the energy market is one of the biggest markets in the world. In fact, it accounts for over 15 percent of the global GDP. Moreover, oil and gas account for more than 70 percent of this energy market. This means that oil and gas will always be present. Due to its importance, petroleum engineering is essential.

Development of oil and gas resources and operations – The development or exploitation of oil and gas fields is the most important aspect of petroleum engineering and hence the majority of employment opportunities in the field come from it. Also, research works on new technologies and methods for the extraction of oil and gas are also conducted by petroleum engineers. For example, they are involved in the design and construction of offshore platforms and oil refineries. Since the demand for energy is continually rising, the exploration process continues as well.

Provision of services related to energy – Apart from developing new energy sources, petroleum engineers must ensure that all other aspects of the industry remain stable. For instance, they are responsible for ensuring the safety of pipelines used throughout the country. In some cases, pipelines can be used to transport natural gas through deserts and mountains. These are examples of how petroleum engineers contribute to ensuring energy stability.

Designing facilities and equipment – The design of facilities and equipment is very crucial to ensure the safe and smooth operation of the entire sector. Examples include designing power stations and oil refineries. In addition, they are also responsible for the maintenance of existing infrastructure. The maintenance includes the replacement of broken pipes and fixing leaks. They also maintain equipment such as compressors and turbines.

What does Petroleum Engineering do

The inclusion of many techniques and equipment, as well as the discovery of various approaches to maximize output, make the Petroleum Engineering area one of the standout distinctive fields to work in. Techniques must be developed in the oil and gas business in response to many unforeseeable events. This necessitates ingenuity and provides a chance for Petroleum Engineers to distinguish themselves from other engineers.

Types of Petroleum Engineers

Reservoir Engineers

Reservoir engineers evaluate the total reserves in a reservoir and also establish its location and create reservoir models utilizing various software programs such as CMG software to gain a better knowledge and visualization of the reservoir beneath. Furthermore, Reservoir Engineers assess distinct fluid characteristics as fluids move from the reservoir to the wellbore, from the wellbore to the surface, and from the surface to the facilities. The changes in the oil and gas characteristics as they move from the reservoir to the wellbore, wellbore to the surface, and surface to facilities have a significant impact on the amount of oil and gas produced, hence also determining the profit.

Reservoir Engineers Work Environment

Reservoir engineers generally work in offices.

Reservoir Engineers pay

The average Reservoir Engineer salary range in the United States typically falls between $34K and $442K according to Glassdoor.

Software use by Reservoir Engineers

Production Engineers

Production engineers come into play after the completion of the wells.  They are in charge of forecasting output and deciding on production intervals in the reservoir. Their job might includes production operations, Gas production, perforation control, sand management, and bottom hole control. They are also in charge of constructing the equipment that would allow the well to produce the most. To become a production engineer you have to have a minimum bachelor’s degree in Petroleum Engineering or a related field with advanced knowledge of gas lift, electric submersible pumps, rod pumping systems design, and optimization.

Completion Engineers

Completion engineers focus on finishing the well in the most efficient manner possible to ensure the safe production of oil and gas. The completion process for offshore and onshore wells is the same. They do the wellbore clean-up job once the well has been drilled. They guarantee a smooth, efficient, and cost-effective flow of fluids to the surface. They investigate and offer efficient solutions to wellbore issues.

Drilling Engineers

Drilling Engineers are responsible for the drilling techniques (drilling operations) used to drill the well. The size, grade, weight, and type of the casing, type of cement, and tubing are controlled by the drilling engineers. Besides drilling techniques, drilling engineers need to know 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.

Drilling engineers generally work at drilling and well sites.

Facilities Engineers

When the well begins to produce, the position of Facilities Engineer becomes available. Facilities engineers collaborate with other engineers, such as Production Engineers. They use various strategies to enhance the product as much as possible to maximize profit. They are also in charge of effective management to accomplish financial and production objectives.

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.
