A network of pipelines, valves, and infrastructure that moves oil, gas, or utilities from a main supply point to end users. Subcontractors are often hired to install, inspect, or maintain these systems. Work scope can include trenching, pipe fitting, and pressure testing across large service areas.
Distribution System
Related Terms
Pressure Pumping
IndustryA well stimulation service involving the high-pressure injection of fluids — such as fracturing fluid, cement, or acid — into a wellbore to improve production or complete the well; for subcontractors, it represents a specialised, equipment-intensive scope of work that typically requires certified operators, dedicated pump trucks, and close coordination with the primary operator on site.
Fired Heater
IndustryA combustion-based unit that uses burners to heat process fluids in oil and gas facilities. Subcontractors are often called in for inspection, refractory work, burner maintenance, and turnaround servicing. Hot work permits and confined space protocols typically apply.
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.
Drillship
IndustryA self-propelled vessel equipped with a drilling rig used for offshore exploration and production in deepwater locations, which subcontractors may be mobilised to for specialised services such as equipment maintenance, inspection, or crew support under strict offshore safety and logistical requirements.
Coal Bed Methane
IndustryCBM (Coal Bed Methane) is natural gas extracted from coal seams rather than conventional reservoirs. Field crews typically handle dewatering operations, pipeline tie-ins, and wellsite maintenance on CBM projects. Work is often spread across large numbers of shallow, closely spaced wells requiring frequent travel between sites.
TIC (Total Installed Cost)
IndustryThe full cost of completing a scope of work, including labour, equipment, materials, and indirect expenses. Subcontractors use TIC to build accurate bids and avoid underpricing complex field installations. Owners and GCs often benchmark TIC when evaluating competing quotes.
