Operational Details
Industrial and oilfield steam cleaning involves the use of a truck mounted tank and compressor, that uses steam under pressure. The hose from the machine is directed to the area that needs to be cleaned. Equipment is often steam cleaned to remove accumulated debris and particles that potentially cause rust. The system may also be used to unthaw equipment in cold weather. In industrial applications, steam cleaning is often used to clean bridge works, and overpasses.

Vacuum trucks also have an oilfield and industrial application. The vacuum units are truck mounted and through using suction, sucks up wet and dry waste materials into a holding tank. It may include cleaning up oil spills, spilled grain, fertilizers, toxic materials, sulphur and other chemicals. The major focus is to remove unwanted materials from a worksite or industrial areas and disposing of it off-site. Transportation of the product cleaned up is integral to this industry. Salt water disposal is much the same process in that it is pumped into a holding tank of a truck and disposed of in a more appropriate location.

Oilfield fire trucks and fire protection include the rental of a fire truck with an operator. This service is similar to when a crane with operator is hired by a contractor. The fire truck however, is on-site as a precautionary measure primarily, and should afire occur, the equipment and expertise is on site to fight the fire. Fire protection provided may also include a crew on site that works either with or independently of the fire truck. Hand tools and pumping units are used to assist in either protecting against, or fighting fires on site.

Seismic survey employers classified in D41-05 are hired to analyze the geophysical data they have obtained. More recently technological advances have included multi-channel digital recording, high speed data processing and a more sophisticated interpretation methods. These methods have helped reduce the number of dry holes being drilled. Computer technology has dramatically reduced the cost of processing data. Explorations can now create accurate, detailed representations of buried rock formations. The cost of shooting and interesting data has dropped almost 80% in the 1990s.

Geophysical work associated with the oil industry include providing geophysical surveys with the use of sophisticated equipment which measures the earth’s formations. However, it does not include any method of seismic exploration as mentioned above. The major activity of a geophysical employer is in analyzing and interpreting data that is often obtained from employers classified in D32-03. The geophysicist is used by oil companies to ensure their findings are kept confidential.
