Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Asset Integrity

The ongoing process of ensuring equipment and structures perform their intended function safely and efficiently. For subcontractors, it drives demand for inspection, maintenance, and repair scopes across the project lifecycle. Clients often mandate documented asset integrity programmes before awarding field service contracts.

Related Terms

Brownfield

Industry

An existing facility—such as a producing well, pipeline, or plant—being modified, upgraded, or maintained rather than built from scratch. For subcontractors, brownfield work often means tighter workspaces, live equipment hazards, and stricter site access requirements. Scopes can change quickly due to unforeseen conditions uncovered during work.

Re-Export (crude)

Industry

Crude oil imported into one country and then shipped out to another without being refined domestically. For subcontractors, re-export activity drives short-term terminal, marine, and logistics work. Contract volumes can spike quickly, so crews and equipment must be mobilisation-ready.

Instrumentation Upgrades

Industry

Replacement or modernisation of sensors, transmitters, and control devices on existing facilities. For subcontractors, this work is often scoped as short-duration projects requiring certified instrumentation technicians. Tight commissioning deadlines and client-supplied materials are common on these jobs.

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.

Guidance Engineer

Industry

A specialist who oversees directional drilling operations, ensuring wellbores are steered accurately to target zones. Subcontractors often supply these roles to operators on a contract basis. They work closely with MWD (Measurement While Drilling) technicians on site.

Pullback

Industry

A horizontal directional drilling (HDD) phase where the product pipe is pulled back through a pre-drilled bore. Subcontractors are often paid a separate pullback rate once this milestone is complete. Delays here directly affect crew scheduling and invoice timing.
