Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

IET (Industrial & Energy Technology)

A broad sector covering technical services and equipment used in oil & gas, power, and industrial facilities. Subcontractors in this space typically provide specialised labour, maintenance, and installation work. Contracts often require trades certification and site-specific safety compliance.

Related Terms

Pipeline Open Season

Industry

A formal period when a pipeline operator solicits capacity commitments from shippers before building or expanding a line. For subcontractors, it signals upcoming construction and maintenance work. Winning bids during this phase often trigger mobilisation timelines and crew planning.

Rig Release

Industry

The formal point when a drilling rig is demobilised and the operator ends the rig contract. For subcontractors, it signals the close of associated scopes of work and triggers final invoicing. Crew demob, equipment retrieval, and close-out documentation should begin immediately.

Oil Sands

Industry

Deposits of bitumen mixed with sand, clay, and water, primarily found in Alberta. Extraction and upgrading operations require large volumes of subcontracted trades, maintenance crews, and specialised equipment. Project cycles are long, but remote site conditions and extreme cold demand strong mobilisation planning.

Turnaround

Industry

A planned shutdown of a facility for maintenance, inspection, and repair. Turnarounds often require large numbers of contractors and subcontractors working intensive schedules.

Vacuum Excavation (vac-Ex)

Industry

A non-destructive digging method that uses high-pressure water or air to loosen soil, then suctions it into a debris tank. Subcontractors use it for safe excavation near buried utilities, pipelines, and cables. It is commonly required on oil and gas sites where mechanical digging poses strike risks.

Exploration Well

Industry

A well drilled in an unproven or lightly tested area to determine whether hydrocarbons are present, often representing shorter-term, high-mobilisation contracts for subcontractors with less predictable follow-on work than development drilling programmes.
