Industry Glossary Term

Mineral Estate

The legal ownership of subsurface resources like oil, gas, and minerals on a property. Subcontractors work under operators who hold mineral rights, so understanding this ownership structure clarifies who controls site access and project authorisation. Disputes over mineral estates can halt work orders without warning.

Related Terms

Switchgear

Industry

Electrical equipment used to control, protect, and isolate power systems on job sites. Subcontractors working near switchgear must follow strict lockout/tagout procedures. Installation and maintenance work often requires certified electricians and site-specific safety permits.

Class 8 Truck

Industry

The heaviest commercial truck classification, with a gross vehicle weight rating over 33,000 lbs. Includes semi-trucks, tankers, and heavy haulers commonly used to move equipment and materials on job sites. Operators require a Class 1 commercial driver's licence in Canada.

STEO (Short-term Energy Outlook)

Industry

A monthly U.S. Energy Information Administration report forecasting near-term oil, gas, and energy prices. Subcontractors use it to anticipate upstream spending trends and project demand for field services. Shifts in STEO forecasts often signal whether operators will ramp up or cut back work programmes.

Gathering System

Industry

A network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.

WTI (West Texas Intermediate)

Industry

A global benchmark crude oil price used to gauge market health and operator spending confidence. When WTI prices drop, clients often freeze or cut field service contracts and budgets. Rising WTI typically signals more work and stronger mobilisation activity for subcontractors.

Appraisal Drilling

Industry

Drilling program that follows an initial discovery to confirm reservoir size and commercial viability. For subcontractors, it means short-term, high-intensity scopes between exploration and full development phases. Mobilisation windows can be tight and contract durations unpredictable.
