Main duties

Petroleum engineers perform some or all of the following duties:
  • Conduct feasibility assessment studies for developing new oil and gas fields
  • Direct and monitor oil and gas drilling operations
  • Develop drilling programs, select sites and specify drilling fluids, bit selection, drill stem testing procedures and equipment
  • Direct and monitor the completion and evaluation of wells, well testing and well surveys
  • Design and select artificial lift machinery, and well and surface production equipment and systems, and specify programs for corrosion control and oil or gas treatment
  • Develop specifications for and monitor and supervise well modification and stimulation programs to maximize oil and gas recovery
  • Analyze reservoir rock and fluid data to design optimum recovery methods and to predict reservoir performance and reserves
  • Monitor and forecast oil and gas reservoir performance and recommend oil recovery techniques which extend the economic life of wells
  • Design, develop and co-ordinate the installation, maintenance and operation of subsea well-head and production equipment.

  • Petroleum engineers may specialize in drilling, production, reservoir analysis or subsea operations.

    Employment requirements

    • A bachelor's degree in petroleum engineering or in a related engineering discipline is required.
    • A master's degree or doctorate in a related engineering discipline may be required.
    • Licensing by a provincial or territorial association of professional engineers is required to approve engineering drawings and reports and to practise as a Professional Engineer (P.Eng.).
    • Engineers are eligible for registration following graduation from an accredited educational program, and after three or four years of supervised work experience in engineering and passing a professional practice examination.

    Additional information

    • There is mobility between petroleum engineering specializations at the less senior levels.
    • Supervisory and senior positions in this unit group require experience.
    • Engineers often work in a multidisciplinary environment and acquire knowledge and skills through work experience that may allow them to practise in associated areas of science, engineering, sales, marketing or management.
