Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Frac Date

The scheduled date when hydraulic fracturing operations begin at a well site. For subcontractors, it drives crew mobilisation, equipment delivery, and invoice timing. Missing a frac date can result in penalties or loss of future work.

Related Terms

Pipeline Commissioning

Industry

The final phase of pipeline construction where systems are tested, cleaned, and activated before handover to the operator. Subcontractors are often mobilised for hydrotesting, pigging, and tie-in work during this stage. Scope can expand quickly, so track change orders closely.

MOU (Memorandum of Understanding)

Industry

A non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.

Pumping Station

Industry

A facility that moves oil, gas, or water through a pipeline using mechanical pumps. Subcontractors are frequently mobilised here for maintenance, inspection, and equipment upgrades. Work scope often includes rotating equipment, instrumentation, and civil trades.

Shut-In Production

Industry

A well or facility that has been temporarily halted from producing oil or gas. For subcontractors, shut-ins often mean suspended work orders and delayed invoicing. Confirm contract terms around standby rates before production stops.

IEA (International Energy Agency)

Industry

An intergovernmental organisation that publishes global energy outlooks and demand forecasts, which subcontractors and field service companies use to anticipate shifts in upstream and downstream activity levels that may affect project pipelines and contract opportunities.

Distributed Fibre-Optic Sensing

Industry

A monitoring technology that uses fibre-optic cables as continuous sensors along pipelines, wellbores, or structures. It detects temperature, strain, and acoustic changes across kilometres of cable in real time. Subcontractors may be hired to install, splice, or maintain these cable systems during construction or integrity projects.
