Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

A midstream processing facility installed along an existing pipeline to extract natural gas liquids like propane and butane. Subcontractors are frequently mobilised for construction, maintenance, and turnaround work at these sites. Work scopes often include compression, refrigeration, and fractionation system servicing.

Related Terms

Export Terminal

Industry

A facility where oil, gas, or LNG is transferred from pipelines or storage for shipment to buyers. Subcontractors are often mobilised here for maintenance, inspection, and commissioning work. Security clearances and site-specific safety certifications are typically required.

GC (General Contractor)

Industry

The prime contractor hired by an owner to manage a project, responsible for awarding and overseeing subcontracts. As a sub, your contract, invoicing, and site access typically flow through the GC. They control your payment terms and schedule, making them your primary business relationship on site.

Lease Road

Industry

A temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.

Hydrogen Hub

Industry

A centralised facility or region where hydrogen is produced, stored, and distributed at scale. For subcontractors, these projects generate long-term work in pipefitting, instrumentation, and equipment installation. Expect strict safety certifications and specialised trade requirements on site.

AFE (Authorization for Expenditure)

Industry

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

Tubular Running

Industry

The process of installing pipe, casing, or tubing strings into a wellbore during drilling or completion operations. Subcontractors providing tubular running services supply specialised crews and equipment such as power tongs and elevators. Accurate job scoping is critical, as rig time is costly and delays directly affect invoicing and contract performance.
