Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Generation Capacity

The maximum electrical output a power generation unit can reliably produce, measured in kilowatts or megawatts. For field crews, it determines whether on-site generators can handle equipment loads at remote worksites. Subcontractors must verify capacity before mobilising power-intensive tools or machinery.

Related Terms

Frac Sand Hauling

Industry

The trucking of proppant (silica sand) from storage terminals to active frac sites. Subcontractors operate on tight dispatch schedules to maintain continuous sand supply during pumping operations. Contracts often include standby rates for wait time at the wellsite.

Well Pairs

Industry

Two horizontal wells drilled together — one injector, one producer — used in SAGD (Steam-Assisted Gravity Drainage) operations. Subcontractors often mobilise crews and equipment to service both wells simultaneously. Expect back-to-back work scopes and coordinated scheduling across a shared pad site.

Spot Work

Industry

Short-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.

Tank Farm

Industry

A designated site containing multiple large storage tanks for oil, gas, or chemicals. Subcontractors frequently perform inspection, maintenance, and cleaning work at these facilities. Access permits and confined space certifications are typically required on site.

Grade Separation

Industry

A crossing where a road, pipeline, or utility passes over or under another route using a bridge or culvert. Subcontractors must account for grade separations when planning equipment moves and material hauls. Permits and escort requirements often apply when loads approach clearance limits.

TOFD (Time-of-flight Diffraction)

Industry

An ultrasonic weld inspection method used to detect and size internal flaws in pipelines and pressure vessels. Subcontractors performing NDT work must hold TOFD-specific certifications to qualify for this scope. It is widely accepted by regulators as an alternative to radiographic testing.
