The base material or surface that a coating, lining, or treatment is applied to, such as steel pipe, concrete, or wood. Subcontractors must assess substrate condition before starting surface prep or application work. Poor substrate quality can affect adhesion, warranty, and job acceptance.
Substrate
Related Terms
DGR (Deep Geological Repository)
IndustryAn underground facility built to permanently store nuclear or hazardous waste deep in stable rock formations. For subcontractors, DGR projects involve highly regulated excavation, tunnelling, and civil work with strict compliance requirements. Expect extensive worker certification, site access controls, and long project timelines.
Grid Hardening
IndustryUpgrades to electrical infrastructure that improve resilience against outages, extreme weather, and physical damage. For subcontractors, it drives demand for line work, equipment installation, and civil construction crews. Contracts often involve tight timelines and utility compliance requirements.
HRSG (Heat Recovery Steam Generator)
IndustryA large boiler unit that captures exhaust heat from gas turbines to produce steam for power generation. Subcontractors are commonly engaged for HRSG installation, maintenance, and inspection scopes. Work typically requires certified welders, boilermakers, and compliance with pressure vessel regulations.
Reservoir Characterization
IndustryThe process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.
Minimum Work Program
IndustryA contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.
EOR (Enhanced Oil Recovery)
IndustryA set of advanced extraction techniques—such as steam injection, chemical flooding, or CO2 injection—used to pull additional crude from mature or low-yield reservoirs, which drives demand for specialised field service crews, equipment operators, and maintenance contractors on long-term site assignments.
