Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Open Season

A formal period when a pipeline or facility operator accepts capacity commitments from potential shippers or users. For subcontractors, it signals upcoming project activity and a chance to position for related field service work. Winning commitments during open season often triggers procurement and mobilisation timelines.

Related Terms

Corrosion Circuit

Industry

A closed electrochemical loop where metal loss occurs between anodic and cathodic areas on a structure. Subcontractors performing inspection or coating work must identify and document active circuits to meet integrity requirements. Unreported corrosion circuits can trigger liability issues and scope disputes on site.

Lower-Tier Subcontractor

Industry

A company or sole operator hired by a subcontractor, rather than directly by the prime contractor or owner. Lower-tier subs often face delayed payment cycles and reduced contract visibility. Understanding your tier position affects lien rights, insurance requirements, and invoice routing.

Trade Contractor

Industry

A specialised subcontractor hired to perform a specific skilled trade, such as electrical, welding, or pipefitting. They are typically engaged by a general contractor rather than the project owner directly. Trade contractors are responsible for supplying their own tools, crew, and trade-specific certifications.

VRU (Vapour Recovery Unit)

Industry

A compression system that captures hydrocarbon vapours from storage tanks or production equipment instead of venting them. Subcontractors are often hired to install, maintain, or service VRUs to meet emissions regulations. Familiarity with VRU work is increasingly required on oil and gas production sites.

Takeaway Capacity

Industry

The available pipeline, trucking, or rail infrastructure to move produced oil, gas, or water away from a wellsite or facility. When takeaway capacity is constrained, operators may shut in wells or delay projects, directly reducing field service work volumes. Subcontractors should monitor regional takeaway conditions as they signal upcoming slowdowns or surges in activity.

Critical Minerals

Industry

Minerals deemed essential to national economies and energy transition, such as lithium, cobalt, and rare earths. Extraction and processing projects for these materials are driving significant new field service demand across Canada. Subcontractors with mining or remote site experience are well-positioned to pursue this growing work.
