A field development that has received formal investment approval from the operator or project owner. For subcontractors, sanction signals that contracts, mobilisation, and work orders are imminent. It marks the transition from planning to active field execution.
Sanctioned Field
Related Terms
Critical Path
IndustryThe 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.
Trade Contractor
IndustryA specialised subcontractor hired to perform a specific skilled trade, such as electrical, welding, or pipefitting. They are typically engaged by a general contractor rather than the project owner directly. Trade contractors are responsible for supplying their own tools, crew, and trade-specific certifications.
Pad Drilling
IndustryA method where multiple wells are drilled from a single surface location, or pad. For subcontractors, this means sustained, back-to-back work cycles with minimal rig-up and tear-down time. Efficient mobilisation and crew scheduling are critical to maintaining productivity across the pad.
Upstream
IndustryThe segment of the oil and gas industry involved in exploration and production (E&P). Includes drilling, completions, and well operations.
Artificial Lift
IndustryA system used to boost production from oil wells that lack sufficient natural pressure to bring fluids to surface. Common methods include rod pumps, ESPs (Electric Submersible Pumps), and gas lift. Subcontractors are often mobilised to install, service, or troubleshoot these systems throughout a well's producing life.
Long-Lead Items
IndustryEquipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.
