Petroleum Engineering

Petroleum engineering is a subdiscipline of petroleum geology concerned with the technical investigation, computer modeling, and forecasting of the future production performance of crude oil and natural gas resources. The petroleum industry inspired the naming of this branch of engineering.

Types of Oil and Gas Engineering

Before pursuing a career in oil and gas engineering, it is in your best interest to learn more about the numerous sub-types of oil and gas engineering. Potential specializations for petroleum engineers include the following:

Mechanical Engineer in Charge of Drilling

This engineer has extensive experience in the oil and gas sector; he is responsible for developing the conceptual framework and designing the drill for each well. They collaborate closely with reservoir engineers to evaluate the site’s specifics and develop a drill plan with the best chance of success. They then took on a supervision role during the drill’s construction. A drilling engineer’s major duty is to find ways to safely and efficiently extract natural resources while protecting the local environment and the workers. These experts spend a third of their time in the office and two-thirds of their time in the field. Engineers who want to succeed in the drilling industry must hone their supervision, management, and negotiation skills.

Production Engineers

Production engineers develop new mining and drilling instruments, such as drill bits and valves, and extraction methods, like horizontal drilling, to maximize the value of every oil field and gas deposit. A production engineer’s duties may include, but are not limited to, choosing the methods and equipment used for well drilling on land and in the water.

Reservoir Engineer

Experts in petroleum and natural gas study reservoirs to learn more about their characteristics and make an accurate production projection for the potential resources there. Developers need a reliable estimate of the amount of oil and gas that can be recovered from a reservoir to make informed decisions about the location. Experts are more inclined to drill in a promising oil field. Reservoir engineers spend much of their time in an office, using modeling and simulation tools to predict oil production.

The petrophysical engineer aids the drilling, production, and reservoir engineers by providing them with tools and analytical procedures for identifying rock and fluid characteristics. Engineers do this to deepen comprehension of the reservoir’s rock-fluid system. The petrophysical engineer will examine the rock-fluid system’s acoustic, radioactive, and electrical characteristics to determine the reservoir’s porosity, permeability, and fluid content. Aside from that, the engineer will collect rocks and well fluids to analyze.
