Duties
Updated Mar 15, 2017

Before oil companies decide to drill a well in a new location, they usually require information from seismic tests to analyze the underground rock formation and its potential for holding reserves of oil or gas. A great deal of time and money is spent on seismic operations, and major decisions are made on the basis of seismic data.

The size of a seismic crew varies with the nature of the job. Crews usually consist of a large team of specialists.

Seismic drillers:

  • drill shot holes that typically are 6 to 20 metres deep
  • load shot holes with predetermined explosive charges that, when detonated, will create underground shock waves for seismic tests (a blaster's permit is required to handle explosive material; for more information, see the Blaster certification profile)
  • transport the equipment required for seismic drilling operations
  • keep continual logs of drilling activity.

Blasters (also known as shooters) organize the blasting equipment used to detonate the loaded charge and control the blasting zone. For more information, see the Blaster occupational profile. During seismic tests, blasters are in constant contact with seismic observers.

Seismic observers operate, maintain and are responsible for the expensive electronic equipment used to record seismic signals. In general, they:

  • perform daily and monthly instrument tests, and ensure all equipment meets tolerance specifications
  • troubleshoot problems and repair recording equipment
  • document recording operations
  • ensure the quality of recorded data at the field level
  • supervise the work of line truck drivers and as many as 30 helpers as they prepare areas for seismic tests.

During seismic tests, observers work in a recording truck and use 2-way radios to direct the work of crew members involved in the tests. In some cases, observers activate the explosives used in tests from inside the recording truck (also known as dog house) or direct the work of blasters who activate explosives from a different location.

Vibrator operators operate vibrating units that sometimes are used instead of explosives to create energy waves in the ground. The vibrator unit is mounted on a medium-sized truck buggy or tracked vehicle that has a large plate attached underneath. When the plate is dropped or vibrated, it creates energy waves in the ground that reflect back to the surface. Often, up to 4 vibrating units are operated at one time.

In general, vibrator operators:

  • organize the placement of equipment
  • operate and maintain vibrator equipment
  • handle and adjust controls to position the vibrating plate
  • co-ordinate activities with seismic observers
  • sometimes drive fuel trucks.

Senior vibrator operators may supervise the work of the vibrator crew or repair equipment as required.

Helpers are inexperienced workers in entry-level positions on seismic crews. After they gain skills and experience, helpers may move to other positions on a crew.

  • Packers clear debris on seismic lines, carry supplies, drive vehicles and assist with other tasks to ensure seismic lines are accessible for other workers. For more information, see the Seismic Line Cutter occupational profile.
  • Driller's helpers work under the direction of seismic drillers. In general, they:
    • carry and load explosive charges (under the direct supervision of a licensed blaster)
    • tamp shot holes.
  • Blaster helpers work under the direct supervision of a licensed blaster. In general, they:
    • guard the area during blasting activities
    • assist blasters in overall operations.
  • Recording helpers, often called jug hounds, assist seismic observers. In preparation for recording activities, observers may require as many as 20 or more recording helpers to haul cables, geophones and other recording equipment, and place and connect recording equipment.

3-dimensional seismic work and heli-portable operations require more equipment and much larger crews including staging managers, line crew bosses and trouble shooters.

Staging managers (sometimes called staging equipment co-ordinators):

  • keep inventories of the equipment being used
  • set up and organize staging sites
  • organize the deployment of personnel and equipment during heli-portable operations.

Line crew bosses (sometimes called line truck drivers):

  • supervise line crew personnel
  • drive and maintain the trucks used to transport personnel and equipment to and from field operations
  • co-ordinate crew members boarding and exiting helicopters
  • arrange the safe and orderly transport of equipment
  • place signage along roadways when necessary.

Trouble shooters work directly under observers and deal with equipment failures. With 3-D seismic work so much equipment is used that several trouble shooters are required to maintain them.

Working Conditions
Updated Mar 15, 2017

Seismic workers may be required to:

  • lift items and carry heavy loads weighing up to 20 kilograms
  • walk long distances through various types of uneven terrain
  • work outdoors in all types of weather conditions
  • travel in small aircraft or helicopters
  • spend extended periods of time away from home, living and working in close contact with a number of people.
  • Strength Required Lift up to 20 kg
Skills & Abilities
Updated Mar 15, 2017

Seismic workers need the following characteristics:

  • the ability to carry heavy loads and walk long distances
  • stamina and flexibility
  • the ability to adapt to a number of different environments (mountains, plains)
  • the ability to work effectively in a team
  • good organizational skills
  • an interest in working outdoors (sometimes in isolated locations) and use various forms of wilderness transportation.

They should enjoy having clear rules and guidelines for their work, and operating and maintaining equipment.

Educational Requirements
Updated Mar 15, 2017

Seismic workers usually are required to have a valid Class 5 driver's licence, with a clean driver's abstract. There are no formal, minimum education requirements for entry-level positions on a seismic crew. However, a high school education and an interest in mathematics, physics and geology are definite assets. Employers generally prefer to hire job applicants who have experience with:

  • manual labour
  • farm equipment
  • mechanical devices
  • heavy equipment
  • electronic equipment.

Seismic workers are trained on the job. Employers also may sponsor safety training related to job duties:

  • Workplace Hazardous Materials Information System (WHMIS)
  • First aid and CPR training
  • Hydrogen Sulfide (H2S) Awareness
  • All-Terrain Vehicle (ATV)
  • Transportation of Dangerous Goods (TDG)
  • General Oilfield Driver Improvement (GODI)
  • Basic Safety Awareness
  • Seasonal Training such as Wildlife Awareness and Cold Weather and Wilderness Awareness.

To advance to more senior positions on a seismic crew, work experience or post-secondary training in an engineering technology, electronics or mechanics is a definite asset.

Employment & Advancement
Updated Mar 15, 2017

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

Seismic workers are employed by geophysical companies.

Employment typically is seasonal.

Seismic crew members usually start as helpers. After gaining experience, they may advance to line supervisor or trouble shooter positions, then to blaster or vibrator operator positions, before moving up to staging co-ordinator and junior observer positions. Experienced seismic crew members who prefer indoor positions may move into positions in centres that process seismic data.

Seismic workers are part of the larger 2011 National Occupational Classification 8615: Oil and gas drilling, servicing and related labourers. In Alberta, 80% 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:

  • 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 4,500 Albertans are employed in the Oil and gas drilling, servicing and related labourers occupational group. This group is expected to have a below-average annual growth of 0.9% from 2016 to 2020. As a result, 41 new positions are forecast to be created each year, in addition to job openings created by employment turnover. Note: As seismic workers form only a part of this larger occupational group, only some of these newly created positions will be for seismic workers.

In 2014, the Petroleum Labour Market Information (PetroLMI) Division of Enform (formally the Petroleum Human Resources Council) indicated that more than 20% of the workforce in the oil and gas industry is eligible for retirement, contributing to the labour demand required to support the industry.

Wage & Salary
Updated Mar 15, 2017

Most employers cover all accommodation costs while the employee is working, and a daily living allowance (or hotshot) of $40-$50 per day is paid to each employee to cover food expenses.
