Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

CCUS (Carbon Capture, Utilization, and Storage)

Technology that captures CO₂ emissions from industrial sites and either stores or repurposes them. Subcontractors are increasingly hired to build, maintain, and service CCUS infrastructure. Familiarity with these projects opens doors to growing work in emissions-reduction programmes.

Related Terms

Mmbtu (million British Thermal Units)

Industry

A standard unit for measuring natural gas energy content, commonly used in supply contracts and fuel billing. Subcontractors working on gas facilities or equipment commissioning will encounter MMBtu-based pricing. It directly affects how fuel costs and energy consumption are calculated on invoices.

Condensate Play

Industry

A development area targeting light liquid hydrocarbons that separate from natural gas at surface. These plays often require specialised separator handling and fluid management equipment. Subcontractors can expect steady demand for well servicing, trucking, and processing facility work.

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.

Alliance Contract

Industry

A long-term agreement where a subcontractor and operator share risks, costs, and rewards on a project. Both parties collaborate closely rather than working at arm's length. Performance incentives and pain/gain sharing are common features.

Work Order

Industry

A formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.

Phase Gate

Industry

A formal approval checkpoint where a project must meet defined criteria before work advances to the next stage. Subcontractors often cannot mobilise, invoice, or begin new scope until the client clears each gate. Delays at phase gates directly impact crew scheduling and cash flow.
