About This Career

Downhole Tool Specialists are responsible for ensuring that the necessary tools for use in oil or gas activity are included in the bottom hole assembly (BHA), equipment at the end of a drill string on a drilling rig. The types of tools selected are based on the oil and gas reservoir formation. They are used during well drilling, evaluation, intervention, completion and production. Once the tools are in position, Downhole Tool Specialists operate and monitor the tool to ensure the work is successfully completed.

Once the BHA is withdrawn from the wellbore, Downhole Tool Specialists perform maintenance and/or repairs on the tools to ready them for future use.

Education: A post-secondary diploma in a mechanical, electrical, electronics, instrumentation, petroleum engineering technology or related discipline is typically required. A post-secondary degree in an applied science discipline, such as engineering, mathematics and geology, is also an option.  

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.
