The primary, large-diameter pipe forming the backbone of a transmission or distribution pipeline system. Subcontractors are typically hired for mainline installation, coating, welding, or hydrotesting scopes. Work on mainline pipe often carries strict inspection and quality requirements.
Mainline Pipe
Related Terms
Perforate
IndustryTo create precisely spaced holes or openings in oil well casing and cement at a target formation depth, allowing hydrocarbons to flow into the wellbore; subcontractors providing perforating services typically work under wireline or coiled tubing crews and must coordinate closely with the operator's completion schedule.
Reamer
IndustryA downhole tool that enlarges or stabilises a borehole during drilling operations. Subcontractors supplying or operating reamers must ensure proper tool specifications match formation conditions. Rental and mobilisation costs are typically scoped into the drilling services contract.
SPE (Society of Petroleum Engineers)
IndustryA global professional organisation that publishes technical standards, research, and best practices used across the oil and gas industry. Subcontractors may reference SPE papers and guidelines to meet operator technical requirements or bid on specialised work.
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.
Tank Farm
IndustryA designated site containing multiple large storage tanks for oil, gas, or chemicals. Subcontractors frequently perform inspection, maintenance, and cleaning work at these facilities. Access permits and confined space certifications are typically required on site.
Mine Reclamation
IndustryThe regulated process of restoring a mine site to an environmentally acceptable condition after operations cease. For subcontractors, it generates specialised scopes including grading, revegetation, and water treatment work. Reclamation projects often extend years beyond mine closure, providing longer-term contract opportunities.
