Industry Glossary Term

Cryogenic Process Equipment

Vessels, piping, and heat exchangers designed to handle fluids at extremely low temperatures, typically below -150°C. Common in LNG (Liquefied Natural Gas) facilities and gas processing plants. Subcontractors must hold specialised certifications and use compatible tools and PPE when servicing this equipment.

Related Terms

Carbonate Formation

Industry

A type of subsurface rock layer—primarily limestone or dolomite—that subcontractors may encounter during drilling, completions, or civil excavation work, often requiring specialised equipment, bit selections, or modified drilling programmes due to its hardness and tendency to cause lost circulation events.

MWD (Measurement While Drilling)

Industry

A real-time data acquisition process used during directional drilling that transmits downhole measurements — such as wellbore trajectory, formation data, and tool orientation — to surface crews without interrupting operations. For subcontractors, MWD services represent a specialised scope of work requiring certified technicians and dedicated equipment, often billed as a separate line item on drilling contracts.

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.

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.

Rotary Rig Count

Industry

A weekly tally of active drilling rigs operating across a region, published by companies like Baker Hughes. Subcontractors use it to gauge market demand and anticipate work volumes. A rising count typically signals increased opportunities for drilling-related field services.

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.
