Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Production Shut-in

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

Related Terms

Grid Interconnection

Industry

The process of connecting a power generation asset to the public electrical grid. For subcontractors, it triggers specific commissioning milestones, inspections, and sign-offs. Delays in interconnection approval can directly impact project timelines and invoicing.

Inventory Drawdown

Industry

The depletion of stored materials, parts, or consumables used during field operations. For subcontractors, rapid drawdown can trigger reorder costs and disrupt project timelines. Tracking drawdown rates helps avoid job-site shortages and unexpected procurement expenses.

NGL (Natural Gas Liquids)

Industry

Hydrocarbons extracted from natural gas, including propane, butane, and condensate. NGL facilities and pipelines generate steady subcontract work in processing, instrumentation, and maintenance. Understanding NGL handling requirements helps crews meet site-specific safety and equipment standards.

JV (Joint Venture)

Industry

A formal business arrangement where two or more companies partner to pursue a specific project or contract, which can affect subcontractors by changing who issues purchase orders, approves invoices, or holds liability on site. Field service companies should confirm early which JV partner is the contracting entity to avoid payment delays or scope disputes.

Predictive Maintenance

Industry

A maintenance approach that uses equipment data and monitoring to forecast failures before they occur. Subcontractors may be dispatched for targeted repairs based on sensor alerts rather than fixed schedules. This reduces emergency callouts and helps crews plan mobilisation more efficiently.

WCB (Workers' Compensation Board)

Industry

Provincial agencies in Canada that provide workplace injury insurance. Contractors must maintain WCB coverage and good standing to work on most sites.
