Co2 Storage (carbon Dioxide Storage)
IndustryThe permanent underground injection of captured CO2 into geological formations like depleted reservoirs or saline aquifers. Subcontractors may support well preparation, pipeline installation, monitoring equipment, and injection operations. Demand for specialised field crews is growing as carbon capture projects expand across Canada.
Tie-In
IndustryA tie-in is the physical connection of new pipeline or equipment to an existing operational system. For subcontractors, tie-in work often requires strict scheduling around shutdowns and may involve additional safety and permitting requirements. Scope changes during tie-ins can affect billing, so clear change-order terms are essential.
Well Spacing
IndustryThe regulated distance between wellbores on a pad or lease area. Tighter spacing means more wells drilled closer together, increasing crew density and equipment demand. Subcontractors should anticipate compressed timelines and overlapping scopes when spacing is tight.
Waterflood
IndustryA secondary recovery method where water is injected into a reservoir to push remaining oil toward producing wells. Subcontractors support waterflood projects through injection well services, pump maintenance, and water handling infrastructure. Work scope can be long-term, offering stable recurring contracts.
Wall Thickness Assessment
IndustryAn inspection process that measures remaining material thickness in pipes, vessels, or structural components to detect corrosion or erosion. Subcontractors are often hired to perform these assessments using UT (Ultrasonic Testing) equipment. Results determine whether assets require repair, replacement, or continued monitoring.
Refinery Throughput
IndustryThe volume of crude oil a refinery processes over a set period, typically measured in barrels per day. Higher throughput means more maintenance, turnaround, and inspection work for subcontractors. Expect busier scopes and tighter schedules when a client ramps up processing capacity.
