Built infrastructure that controls or directs water flow, such as dams, weirs, cofferdams, and retention ponds. Subcontractors working near these structures often face strict safety and permitting requirements. Scopes may include installation, inspection, maintenance, or dewatering support.

Related Terms
LOL (Limitation of Liability)
IndustryA contract clause capping the maximum amount a party can be held responsible for if something goes wrong. For subcontractors, this limits financial exposure from claims, damages, or project losses. Always review these caps carefully — they may be set far below your actual risk.
Wastewater Injection
IndustryThe process of pumping produced water or other fluid waste deep into underground formations for disposal. Subcontractors operating injection pumps or wellbore equipment must meet strict provincial and federal disposal regulations. Work often requires specialised well integrity certifications and detailed fluid volume reporting.
Wellpad
IndustryA prepared, levelled site where one or more oil or gas wells are drilled and completed. Subcontractors often mobilise to a wellpad for multi-well scopes, making it a key unit for planning labour and equipment. Pad size and well count directly affect job duration and invoicing cycles.
Ngl (natural Gas Liquid) Fractionator
IndustryA processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.
Opec+ (organisation of the Petroleum Exporting Countries Plus)
IndustryAn alliance of oil-producing nations that controls global crude output levels. Their production decisions directly affect upstream activity and subcontractor demand. When OPEC+ cuts output, drilling and field service work typically slows; increases often trigger new project mobilisations.
Carbon Dioxide Treater
IndustryA vessel or system used on oil and gas sites to remove CO2 (Carbon Dioxide) from produced gas or water streams. Subcontractors are often hired to install, service, and inspect these units. Proper handling requires H2S and pressure safety training.
