About This Career

Drilling Fluids Representatives work alongside the drilling crew to ensure that the drilling fluid used on an oil or gas well site meets required specifications for the type of well in development and is compatible with the oil or gas formations being drilled. They also provide guidance in the event of any issues.

Drilling Fluids Representatives ensure that the proper materials are supplied as needed. They may be required to undertake the activities of an on-site Drilling Fluids Specialist, which requires strong knowledge of drilling fluids and their properties. This occupation is commonly referred to as the Mud Man.

Drilling Fluids Representatives test fluids throughout an operation to ensure compliance with specifications, and maintain and calibrate the necessary test equipment. They advise crews on the safe handling and use of drilling fluids, and provide expert advice on the proper disposal of waste fluids. They may also coordinate with Solids Control Technicians to ensure that drilling fluids are being properly cleaned for re-use.

Education: A post-secondary degree in a science or engineering discipline is typically required, although less formal education with 8-10 years of drilling experience may also be acceptable.

Employment: This occupation is found in both onshore and offshore environments and is typically employed in the oil and gas services sector of the oil and gas industry.

The forestry industry comprises establishments primarily engaged in growing and harvesting timber on a long production cycle (of ten years or more). Industries in this subsector specialize in different stages of the production cycle. Reforestation requires production of seedlings in specialized nurseries. Timber production requires natural forests or suitable areas of land that are available for a long duration. The maturation time for timber depends upon the species of tree, the climatic conditions of the region, and the intended purpose of the timber. The harvesting of timber, except when done on an extremely small scale, requires specialized machinery unique to the industry. The gathering of forest products, such as gums, barks, balsam needles and Spanish moss, are also included in this subsector.
