Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Multi-Well Pad

A single surface location where multiple wells are drilled and completed in sequence. For subcontractors, this means extended site presence, higher mobilisation value, and repeated service cycles from one location. Scheduling and crew continuity are critical to securing ongoing work across the pad.

Related Terms

Peaking Facility

Industry

A peaking facility is an energy plant activated only during periods of high demand, such as extreme cold snaps. For subcontractors, these sites generate short-notice, high-intensity work orders requiring rapid crew mobilisation. Expect compressed timelines and premium billing opportunities during activation periods.

Transmission Line

Industry

A high-voltage power line that moves electricity over long distances between generation sources and distribution networks. Subcontractors often support transmission line projects through clearing, trenching, tower erection, and right-of-way maintenance work.

TD (Total Depth)

Industry

The maximum depth reached by a drilling rig during well construction, measured from the surface to the bottom of the wellbore. For subcontractors, TD determines project scope, equipment requirements, and billing milestones as it marks the completion of the drilling phase.

Hydrostatic Testing

Industry

A pressure integrity test where pipelines, vessels, or equipment are filled with water and pressurised to detect leaks or weaknesses. Subcontractors are often hired to perform or witness these tests before commissioning. Proper documentation is critical, as clients and regulators require certified test records.

Run Schedule

Industry

A timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.

Long-Cycle

Industry

Refers to large capital projects with lead times and development phases spanning several years. For subcontractors, long-cycle work offers extended contract visibility but requires patience on mobilisation and payment timelines. Budget cycles and scope changes are common over the project life.
