Companies that build large-scale infrastructure such as roads, bridges, pipelines, and earthworks. For subcontractors, they are common prime contractors who hire specialised field crews and equipment operators. Understanding their project structures helps subs navigate bidding, scheduling, and payment terms.
Heavy Civil Contractors
Related Terms
Bbl/d (barrels Per Day)
IndustryA measure of how much oil a well or facility produces daily. Operators use Bbl/d targets to schedule field service crews and equipment. Higher Bbl/d often means more maintenance contracts and longer mobilisation windows for subcontractors.
Tubular Running
IndustryThe process of installing pipe, casing, or tubing strings into a wellbore during drilling or completion operations. Subcontractors providing tubular running services supply specialised crews and equipment such as power tongs and elevators. Accurate job scoping is critical, as rig time is costly and delays directly affect invoicing and contract performance.
Derivative Goods
IndustryProducts created by processing or transforming raw materials supplied under a contract, such as fabricated components or treated fluids. Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.
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.
Gathering Infrastructure
IndustryThe network of pipelines, compressors, and processing facilities that collect hydrocarbons from wellheads and move them to processing or transmission points. For subcontractors, it represents a major source of construction, maintenance, and inspection work. Projects often run concurrently with drilling programmes, creating tight scheduling demands.
Service Company
IndustryA company that provides specialized services to oil and gas operators, such as drilling, completions, workover, transportation, or maintenance. Also called oilfield services (OFS).
