Global Oil, Gas and Petrochemical Job Career Pathway

An oil, gas, or petrochemical operator monitors, operates, and maintains equipment and processing facilities used to extract and produce energy and chemical products. The job is essential for maintaining safety, efficiency, and continuous production in a high-stakes environment. ⁽¹⁾

What is a plant operator?

A plant operator is a professional who operates, monitors and maintains machinery in an industrial plant. Your job involves using machines like cranes, backhoes, excavators, bulldozers and trenchers. You perform jobs like excavation, lifting, crushing rocks and transporting materials from one place to another. Many modern industrial plants have highly automated machines and equipment that use computer controls to handle different processes. In such cases, you monitor progress, observe the gauges, check the valves and operate alarms and switches from a centralized control room ⁽¹¹⁾

Operator roles and responsibilities

The day-to-day duties for an operator depend on whether they work in the “upstream” sector (exploration and production), “midstream” (transportation and storage), or “downstream” (refining and processing). ^{(2) (3)}

Common duties

Monitor and control processes: From a control room, operators use Distributed Control Systems (DCS) and Supervisory Control and Data Acquisition (SCADA) to monitor temperature, pressure, flow, and other critical process variables.
Execute field operations: Operators perform hands-on tasks like adjusting valves, starting and stopping pumps and compressors, and conducting routine maintenance.
Conduct inspections and troubleshooting: They perform regular patrols to check for leaks, malfunctions, or other unusual conditions. When issues arise, they troubleshoot to identify the problem and initiate corrective action.
Ensure safety and compliance: Operators strictly follow safety protocols and procedures, including preparing and issuing “Permit to Work” documents for maintenance jobs.
Maintain records: They keep detailed logs of meter readings, production volumes, and any incidents or maintenance activities that occur. ^{(4) (5)}

Sector-specific duties

Upstream (Exploration and production): Field operators focus on controlling the flow of oil, gas, and water from wellheads to processing facilities. This can include monitoring well tests and injection processes for enhanced oil recovery.
Midstream (Pipelines and storage): Operators in this sector oversee the safe and efficient transportation of resources through pipelines and transfer them into storage tanks. They are often involved in “pigging” operations, which involve sending devices through the pipeline for cleaning and inspection.
Downstream (Refining and petrochemicals): In refineries and chemical plants, operators are responsible for specialized processes like distillation, catalytic cracking, and blending to create finished products such as gasoline, diesel, and plastics.^{(7) (8)}

Typical work environment

The environment can be demanding and requires working in various conditions.

Onshore vs. Offshore: While onshore operators may work regular shifts closer to home, offshore operators work on platforms or vessels and follow a rotational schedule, often with longer shifts and extended time away.
Shift work: Most plants operate 24/7, requiring operators to work on a rotational shift schedule, including nights, weekends, and holidays.
Physical demands: The job can be physically demanding, with tasks that involve working outdoors in different weather conditions, climbing stairs and ladders, and lifting equipment.^{(9) (10)}

Qualifications and skills

Education: A high school diploma or equivalent is the basic requirement, but many employers prefer candidates with vocational training, technical certificates, or an associate’s degree in a relevant field.
Experience: Several years of experience in an industrial or plant environment is often necessary, especially for more advanced or senior positions.
Technical knowledge: A strong understanding of process equipment, control systems, and mechanical and electrical principles is crucial.
Essential soft skills: Top-performing operators possess strong problem-solving skills, attention to detail, excellent communication, and the ability to work effectively under pressure. ⁽¹²⁾

Some of the soft skills required are:

Leadership skills
Teamwork capabilities
Communication skills
Good judgment in high-pressure situations
Ability to work onsite for extended periods
Physical stamina
Creative thinking abilities
Problem solving skills
Attention to detail ⁽¹³⁾

Career outlook and compensation

Job Outlook: Despite the global energy transition, the oil and gas industry remains resilient and continues to require skilled operators to meet global energy demand.
Compensation: Salaries can be very competitive, especially for experienced offshore or Senior DCS Operators. Compensation is often higher for roles with increased safety risks and time away from home. In Qatar, for example, salaries for plant operators are among the highest in the region.
The largest job family within the upstream energy industry, Operator jobs typically involve the specialised operation of control systems and equipment related to plant and facilities, heavy equipment, rigs, wells and pipelines. Operators can work in both the upstream or downstream industry’s.⁽¹³⁾
