Grid-Tie

A drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.

A formal document issued under a master contract that authorises a specific scope of work, timeline, and budget. Subcontractors use task orders to mobilise crews and bill for individual job phases. Each task order typically carries its own number for invoicing and cost-tracking purposes.

A pipeline or conduit installation technique that avoids open excavation, using methods like HDD (Horizontal Directional Drilling) or pipe bursting. Subcontractors use it to cross roads, waterways, or environmentally sensitive areas with minimal surface disruption. Specialised equipment and certifications are typically required, affecting crew composition and bid pricing.

The heaviest category of commercial trucks, rated at over 33,001 lbs gross vehicle weight. Common in oil and gas field work for hauling heavy equipment, frac sand, and pipe. Operators require a Class 1 licence in Canada.

The linking of separate communication systems so field crews, dispatch, and client sites can share data in real time. For subcontractors, this enables job updates, timesheets, and safety reports to flow between systems without manual re-entry. Reliable interconnection reduces billing delays and keeps remote sites aligned with head office.

A scope-of-work term covering all field service activities from the producing wellhead to the point of water disposal or treatment. For subcontractors, it defines mobilisation boundaries and billable work limits on produced-water handling projects. Knowing this scope prevents disputes over who owns each task segment.
