Gas plant operators take care of the day-to-day operation of natural gas plants. They monitor all the units in the plant to ensure everything runs smoothly.
Gas plant operators’ duties vary depending on the size of the plant. Large facilities often require more operators and their jobs are specialized. Smaller gas plants may require fewer people who each have a wider range of duties.
Junior operators, sometimes called trainee operators, work in units in gas plants. For example, they may work in the sulphur handling unit where sulphur is removed. Or they may work in the treating unit where water and impurities are removed and the gas is separated into components. Under the direction of unit operators, junior operators:
Unit operators ensure that an entire unit operates smoothly. They train and supervise junior operators and assist with or conduct equipment inspections. They are also in charge of:
Senior operators, sometimes called chief operators or lead hands, are in charge of operating several units. They usually are the most experienced operators on their shift. Senior operators spend most of their time working in a control room. They monitor numerous control panels, charts and an alarm system that sounds when a problem occurs. If adjustments need to be made in a unit, or an alarm goes off, senior operators call the unit operators concerned and outline the necessary procedures.
In sour gas plants, operators are trained in emergency evacuation and firefighting procedures.
Much of the work in gas plant operations is routine. Gas plant operators may go for long periods of time without a problem and then a serious failure or complication may occur. When this happens, operators must analyze the problem and act quickly and correctly.
Depending on the design of the plant, junior operators may spend about half of their time outdoors. Their job requires a lot of walking and lifting. Unit operators spend most of their time indoors but may be required to work outside when problems arise with outdoor equipment. Senior operators spend much of their time in the control room.
Gas plants operate 24 hours a day so operators work 8- or 12-hour shifts. They may need to work long hours to complete special tasks. Operators must follow safety precautions to avoid injuries resulting from exposure to toxic chemicals and gases.

In gas plants that use generating sources other than steam, operators may not need specific formal education. However, a high school diploma with courses in mathematics, chemistry and physics is a definite asset. The following safety courses also may be required or recommended:
Gas plants with power boilers or sulphur recovery units require that operators have an Alberta Power Engineering Certificate. For details about power engineering certification, see the Power Engineer occupational profile. Most employers also want operators to complete at least 1 or 2 Gas Processing Operations (GPO) courses.
Some companies provide in-house training opportunities to help gas plant operators advance to more senior positions.
Post-secondary schools that offer power engineering programs also may offer GPO courses and other gas plant operations training by distance education (computer-managed learning or modularized materials).
The following schools offer programs or courses that are related to this occupation but are not required to enter the field.

Gas plant operators work for oil and gas companies in gas plants. In general, these are located as close as possible to gas fields. Alberta has hundreds of gas plants, some near major cities and others in remote areas.
Individuals often start in field positions or as junior operators. Advancement to more senior positions such as unit operator and senior operator usually depends on experience and education. In gas plants that require power engineering certificates, operators may need higher certification to advance to senior positions.
Senior operators may move into supervisory positions. They may then advance to management positions located either at the plant or in major cities.
