Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Pigging

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.

Related Terms

Basemat

Industry

The reinforced concrete foundation slab supporting a structure's entire load. Subcontractors doing civil or concrete work often mobilise early to complete basemat pours before other trades arrive. Scheduling and cure time directly affect downstream scopes.

Scoping Period

Industry

A defined window where the prime contractor or operator outlines project requirements before awarding contracts. Subcontractors use this time to assess fit, prepare bids, and flag resource or equipment needs. Missing this window often means missing the contract opportunity entirely.

Refractory Lining

Industry

Heat-resistant material installed inside furnaces, boilers, and process vessels to protect steel from extreme temperatures. Subcontractors are often hired for installation, inspection, and repair during turnarounds. Proper curing and dryout procedures are critical to avoid costly failures.

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.

Natural Decline Rate

Industry

The rate at which a well's production drops over time without operator intervention. For subcontractors, this signals reduced worksite activity and fewer service calls as output falls. Anticipating decline helps crews and companies plan for shifting demand across a field.

Crude Oil Stock Build

Industry

A rise in stored crude oil inventories, signalling weak demand or oversupply. This often triggers operators to slow production, which can delay or reduce field service work orders. Subcontractors should monitor stock build trends as an early indicator of project slowdowns.
