Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Rig-Released

Status indicating a drilling rig has been formally stood down and all associated services are no longer required. For subcontractors, it triggers demobilisation, final invoice submission, and crew release. Contracts often specify notice periods and standby rates tied to this status.

Related Terms

NPRA (National Petroleum Reserve-alaska)

Industry

A large federally managed area in northwest Alaska open to oil and gas exploration and development. Subcontractors working here face extreme remote logistics, strict federal permitting, and seasonal access windows. Mobilisation costs and compliance requirements are significantly higher than conventional onshore projects.

Co2 Storage (carbon Dioxide Storage)

Industry

The permanent underground injection of captured CO2 into geological formations like depleted reservoirs or saline aquifers. Subcontractors may support well preparation, pipeline installation, monitoring equipment, and injection operations. Demand for specialised field crews is growing as carbon capture projects expand across Canada.

Umbilicals, Risers, and Flowlines

Industry

Collectively referred to as URF, these are the subsea infrastructure components that connect wellheads to production facilities — umbilicals carry control fluids and signals, risers bring production to surface, and flowlines move product along the seabed — subcontractors are commonly engaged for their installation, inspection, maintenance, and integrity management work. Understanding the distinctions between these systems helps field crews accurately scope work orders, apply correct certifications, and bill against the right line items in offshore or subsea contracts.

Condensate

Industry

A light liquid hydrocarbon that separates from natural gas during production and processing. Subcontractors handling condensate must follow strict hazmat protocols, as it is highly volatile and flammable. It is often measured and valued separately from crude oil on production sites.

T&D (Transmission and Distribution)

Industry

The network of high-voltage power lines, towers, substations, and local distribution lines that move electricity from generators to end users. Subcontractors in this sector handle tasks like line construction, pole installation, and substation work. T&D projects are often awarded through utility frameworks or provincial grid operators.

FID (Final Investment Decision)

Industry

The point when a project owner formally approves funding and commits to proceeding with a major project. For subcontractors, FID is the trigger that converts preliminary work into confirmed scopes and purchase orders. Mobilisation planning, crew hiring, and equipment sourcing typically begin after FID is announced.
