Industry Glossary Term

Hydraulic Fracturing

A well stimulation process where fluid is pumped at high pressure to crack subsurface rock and release oil or gas. Subcontractors are commonly engaged for pump operations, fluid handling, and equipment transport during frac campaigns. Work is often fast-paced and shift-intensive, with strict site access and safety requirements.

Related Terms

BESS (Battery Energy Storage System)

Industry

A large-scale battery installation that stores and dispatches electrical power on remote or off-grid job sites. Subcontractors may be hired to install, commission, or maintain these units alongside diesel generators or solar arrays. Familiarity with high-voltage systems and OEM safety protocols is typically required.

Minimum Work Program

Industry

A contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.

WCB (Workers' Compensation Board)

Industry

Provincial agencies in Canada that provide workplace injury insurance. Contractors must maintain WCB coverage and good standing to work on most sites.

FPSO (Floating Production, Storage and Offloading Unit)

Industry

A ship-shaped offshore vessel that processes and stores crude oil or gas directly at sea, then transfers it to tankers — for subcontractors, FPSOs represent remote, long-duration worksites with strict offshore safety certification requirements, specialised crew rotation logistics, and scope that can span topside maintenance, marine systems, and instrumentation work simultaneously.

OSHA

Industry

Occupational Safety and Health Administration. The US federal agency responsible for workplace safety regulations. Compliance with OSHA standards is required for contractors working in the United States.

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.
