Industry Glossary Term

Well Pair

Two parallel horizontal wells — one injector, one producer — used together in SAGD (Steam Assisted Gravity Drainage) operations. Subcontractors are typically mobilised to service both wells as a single scope. Expect coordinated drilling, completions, and maintenance schedules across both wellbores.

Related Terms

Long-Cycle Project

Industry

A major capital project with a development timeline spanning several years, such as an LNG (Liquefied Natural Gas) facility or oilsands expansion. For subcontractors, these projects can offer extended contract opportunities but require careful cash-flow planning. Mobilisation costs and payment schedules must be negotiated carefully, as revenue is spread over a long horizon.

Brownfield Site

Industry

An existing facility or infrastructure that is being modified, expanded, or recommissioned rather than built from scratch. Subcontractors should expect tighter work windows, live-equipment hazards, and strict permit-to-work requirements. Scheduling and coordination with ongoing operations are critical on brownfield projects.

Frontage Road

Industry

A secondary road running parallel to a highway, providing access to adjacent worksites, lease roads, or staging areas. Subcontractors often use frontage roads for heavy equipment moves or crew dispatch without entering main traffic. Confirm load restrictions and municipal permits before routing oversized hauls.

Tidewater

Industry

Coastal or tidal waterway areas where marine and land-based field operations intersect. Subcontractors working tidewater zones often face dual regulatory requirements and tidal scheduling constraints. Mobilisation windows and equipment access depend heavily on tidal cycles.

Marine Infrastructure

Industry

Offshore and coastal structures such as platforms, jetties, pipelines, and subsea systems where field work is performed. Subcontractors must hold marine-specific certifications and follow offshore safety protocols. Mobilisation costs and logistics are typically higher than onshore projects.

Crawler Crane

Industry

A large lifting crane mounted on tracked undercarriage, used for heavy lifts on unstable or soft ground at oil and gas and construction sites. Subcontractors often source these through specialised rigging firms on a day-rate or project basis. Confirm ground-bearing capacity and operator certifications before mobilising.
