The sequence of tasks that directly controls a project's completion date. Delays to any critical path activity push the whole project's finish date back. Subcontractors on critical path work face tighter scrutiny and stronger pressure to meet scheduled milestones.
Critical Path
Related Terms
Caisson
IndustryA watertight steel or concrete structure used to support foundations in offshore or waterlogged environments. Subcontractors may be scoped to install, inspect, or perform maintenance work on caissons. Access and confined space protocols often apply.
Cavern Storage
IndustryUnderground storage facilities carved out of salt formations or rock, used to hold large volumes of natural gas, crude oil, or other hydrocarbons. Subcontractors handle construction, maintenance, inspection, and integrity testing at these sites, often needing confined-space and geotechnical certifications. Injection and withdrawal seasons create predictable maintenance windows, helping field service companies plan mobilisation.
SPR (Strategic Petroleum Reserve)
IndustryA government-held emergency stockpile of crude oil that, when released or replenished, can trigger short-term surges in drilling, transportation, and maintenance contracts as operators respond to shifting supply directives. Field service companies should monitor SPR activity as an indicator of near-term work mobilisation and pricing conditions in their region.
Farm-Out
IndustryA farm-out occurs when an operator transfers part of its working interest in a well or lease to another company. For subcontractors, this can mean a change in who issues your work orders, purchase orders, or payment approvals mid-project. Always confirm the new operator's billing procedures and verify your contract remains valid under the new arrangement.
Minimum Work Program
IndustryA contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.
Duct Bank
IndustryA grouped arrangement of conduits encased in concrete, used to route electrical or communication cables underground on job sites. Subcontractors installing or excavating near duct banks must follow strict dig protocols to avoid damaging live services. Identifying duct bank locations early prevents costly delays and liability.
