Employment & Advancement
Updated Dec 19, 2016

Below-average occupational growth is expected in Alberta for 2016 to 2020. Job openings are a result of employment turnover and newly created positions.

Natural gas compression technicians are employed by:

  • natural gas producers
  • manufacturers of compressor packages
  • power system providers
  • natural gas engine and compressor service providers.

With more education and experience, they may advance to supervisor or superintendent positions. Alberta certified journeyperson natural gas compression technicians who have the supervisory or management skills required by industry may apply for an Achievement in Business Competencies Blue Seal by contacting Alberta Apprenticeship and Industry Training.

Natural gas compression technicians are part of the larger 2011 National Occupational Classification 7311: Construction millwrights and industrial mechanics (except textile). In Alberta, 75% of people employed in this classification work in the following industries:

The employment outlook in this occupation will be influenced by a wide variety of factors including:

  • time of year (for seasonal jobs)
  • trends and events affecting overall employment (especially in the industries listed above)
  • location in Alberta
  • employment turnover (work opportunities generated by people leaving existing positions)
  • occupational growth (work opportunities resulting from the creation of new positions that never existed before)
  • size of the occupation.

Over 10,900 Albertans are employed in the Construction millwrights and industrial mechanics (except textile) occupational group. This group is expected to have a below-average annual growth of 1.3% from 2016 to 2020. As a result, 142 new positions are forecast to be created each year, in addition to job openings created by employment turnover. Note: As natural gas compression technicians form only a part of this larger occupational group, only some of these newly created positions will be for natural gas compression technicians. 

Employment turnover is expected to increase as members of the baby boom generation retire over the next few years.
