Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Acre-Feet

A volume measurement equal to one acre of surface area filled one foot deep, roughly 1,233 cubic metres. Common in water management contracts for tailings ponds, frac water storage, and site remediation. Subcontractors may be scoped and billed based on acre-feet of material moved or treated.

Related Terms

Pigging

Industry

The process of running a device called a pig through a pipeline to clean, inspect, or displace fluids. Subcontractors are often hired to provide pig launcher and receiver equipment, operators, and associated support services. Pigging scopes can range from routine maintenance runs to complex inline inspection campaigns.

Secondary Stress

Industry

Indirect mechanical stress that develops in structures or piping due to thermal expansion, settlement, or equipment movement. Unlike primary stress, it isn't caused by direct applied loads. Subcontractors must account for it during installation and inspection to avoid material fatigue and warranty disputes.

JIP (Joint-industry Project)

Industry

A cost-sharing initiative where multiple operators or companies fund research, technology development, or industry challenges together. For subcontractors, JIPs can open doors to new contracts, but procurement processes are often slow and heavily governed. Understanding which operators are involved helps you identify who holds the real budget authority.

Strait of Hormuz

Industry

A critical shipping chokepoint between Oman and Iran controlling roughly 20% of global oil flow. Disruptions here can spike material costs and delay equipment deliveries for subcontractors. Budget contingencies and procurement timelines should account for geopolitical risk in this corridor.

Data Mesh

Industry

A decentralised approach where different teams own and share their own operational data directly. For subcontractors, it means job site data—timesheets, inspection reports, equipment logs—flows more easily between your systems and the prime contractor's. Reduces bottlenecks caused by waiting on a single centralised IT team to manage data access.

Drilling Optimisation

Industry

The process of improving drilling speed, efficiency, and cost performance on a well. Subcontractors may be asked to adjust crew rotations, equipment deployment, or service timing to support optimisation targets. Faster drilling cycles can shorten contract durations, affecting your crew planning and invoicing schedules.
