Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Hot Shot

Expedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.

Related Terms

Permitting Reform

Industry

Changes to government approval processes that reduce delays for energy and construction projects. Faster permits mean earlier mobilisation and more predictable project timelines for subcontractors. This can directly affect when crews and equipment are scheduled and when work orders are issued.

Spring Break-Up

Industry

The seasonal period when melting snow and frost causes ground conditions to soften, restricting heavy equipment access to remote sites. Municipalities impose road bans limiting load weights, delaying material hauls and crew mobilisation. Subcontractors should plan for project slowdowns and reduced billable hours during this window.

PWHT (Post-weld Heat Treatment)

Industry

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

Shale Gas

Industry

Natural gas extracted from shale rock formations using hydraulic fracturing and horizontal drilling. For subcontractors, shale gas projects drive high demand for frac crews, equipment operators, and site services. Work is often concentrated in multi-well pad campaigns, creating steady but intense mobilisation cycles.

Turnaround

Industry

A planned shutdown of a facility for maintenance, inspection, and repair. Turnarounds often require large numbers of contractors and subcontractors working intensive schedules.

500-Kv Transmission Line

Industry

A high-voltage power line carrying 500 kilovolts, typically built to move bulk electricity across long distances. Subcontractors on these projects must hold specialised high-voltage certifications and follow strict safety exclusion zones. Work scopes often include tower erection, conductor stringing, and ground grid installation.
