Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Crown Land Sale

A government auction where energy companies bid on licences to explore or develop publicly owned land. Winning bids signal upcoming drilling and field activity in that area. Subcontractors watch these sales to anticipate new work and mobilise resources early.

Related Terms

Greenfield

Industry

A project built from scratch on a previously undeveloped site, with no existing infrastructure. For subcontractors, this means longer mobilisation timelines and higher early-stage labour demand. Expect more scope changes and stronger opportunities for long-term contract work.

Onshore Acreage

Industry

Land-based areas leased or licensed by operators for exploration and production activities. For subcontractors, it defines where field work is scoped, mobilised, and contracted. Acreage size and location directly affect crew logistics, travel costs, and service demand.

Trade Contractor

Industry

A 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.

In-Service Date

Industry

The date when equipment or a facility is officially commissioned and begins active operation. For subcontractors, this date often triggers billing milestones, warranty periods, or contract close-out requirements. Missing this date can result in penalties or delayed final payment.

Gathering System

Industry

A network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.

Master Service Agreement (MSA)

Industry

A contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.
