Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

IIJA (Infrastructure Investment and Jobs Act)

A major U.S. federal law passed in 2021 that funds roads, bridges, pipelines, and energy infrastructure projects. It drives significant contract opportunities for subcontractors in civil, pipeline, and utility work. Prevailing wage and Buy America requirements often apply, affecting labour costs and material sourcing.

Related Terms

Paying Quantities

Industry

A legal threshold where a well produces enough oil or gas to justify continued operations and generate profit. For subcontractors, it determines whether a site stays active and whether ongoing service contracts remain in force. Loss of paying quantities can trigger contract suspension or early termination clauses.

Gas-Directed Drilling

Industry

A drilling approach where well placement decisions are guided by real-time gas readings from formation data. Subcontractors should expect frequent operational pauses for data evaluation and possible scope changes. Mud logging and wellsite geology crews are typically in high demand on these programmes.

Substrate

Industry

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.

Pipeline Tie-in

Industry

A pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.

Bonus Bid

Industry

A lump-sum payment made by an operator to secure rights to a lease block, separate from royalties. For subcontractors, a large bonus bid signals operator commitment and can indicate upcoming project activity in that area.

Development Sanction

Industry

The formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.
