Industry Glossary Term

Gyroscopic Guidance

A downhole navigation system that uses gyroscopes to track drill bit position and direction without magnetic interference. Subcontractors use it in areas where magnetic tools fail, such as near casing or in high-latitude regions. Accurate wellbore placement reduces costly corrections and keeps projects on schedule.

Related Terms

Kelly Bar

Industry

A heavy, telescoping steel rod that transmits rotary torque from a drill rig to the auger or cutting tool. Subcontractors operating foundation or piling rigs must inspect kelly bars regularly for wear and cracking. Damage affects drilling performance and can cause costly downtime on tight project schedules.

Natural Hydrogen

Industry

Hydrogen gas that occurs naturally underground, now being explored as a clean energy source. Subcontractors may encounter exploration and drilling projects targeting natural hydrogen deposits. It is an emerging sector creating new field service opportunities across Canada.

Hot Shot

Industry

Expedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.

Subsea Production System

Industry

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.

Class 8 Truck

Industry

The heaviest commercial truck classification, with a gross vehicle weight rating over 33,000 lbs. Includes semi-trucks, tankers, and heavy haulers commonly used to move equipment and materials on job sites. Operators require a Class 1 commercial driver's licence in Canada.

Vam Connections

Industry

Premium threaded pipe connections used in oil and gas drilling and completion operations. Subcontractors handling, installing, or inspecting VAM connections must follow strict torque specs and handling procedures. Improper makeup can result in costly downhole failures and liability exposure.
