A above-ground tracking system used in horizontal directional drilling (HDD) to monitor and guide a drill head's position underground. A handheld receiver walks the surface above the drill path, reading signals from a transmitter in the drill head. Subcontractors use this data to steer accurately and document bore paths for client sign-off.

EIA (Energy Information Administration)
IndustryA U.S. federal agency that publishes energy data, forecasts, and market reports. Subcontractors use EIA reports to track oil and gas price trends and anticipate shifts in project demand. Monitoring EIA data helps field service companies time bids and resource planning.
Heavy Civil
IndustryLarge-scale infrastructure construction involving earthworks, bridges, roads, and foundations. Subcontractors in this sector typically supply specialised equipment, civil crews, or concrete services. Contracts are often high-value but require significant bonding and insurance capacity.
Permanent Magnets
IndustryFixed magnets that retain their magnetic field without external power, used in motors, sensors, and lifting equipment on job sites. Subcontractors handling this equipment must follow strict handling and storage protocols to prevent injury or tool damage. They are common in downhole tools, generators, and magnetic lifting devices.
Surface Miner
IndustryA large self-propelled machine that cuts, crushes, and loads material in a single pass without blasting. Subcontractors operating surface miners must hold specialised equipment certifications and follow strict site safety protocols. Common in oil sands and open-pit construction projects across Western Canada.
Ip30 (initial Production 30-Day Rate)
IndustryA well's average daily output during its first 30 days of production. Operators use IP30 figures to evaluate well performance and plan follow-on service scopes. Strong IP30 results often drive faster mobilisation of additional field crews and equipment.
Hyperscale
IndustryRefers to massive, rapidly expanding infrastructure projects — such as data centre campuses or LNG facilities — that require large volumes of specialised subcontractors in a compressed timeframe. For field service crews, hyperscale projects offer high-volume work but demand fast mobilisation and flexible staffing.
