IET (Industrial & Energy Technology)

The open entrance and exit points of a tunnel where underground meets surface operations. For subcontractors, portals are critical mobilisation zones for equipment, crews, and material staging. Access, congestion, and safety controls at portals directly affect your crew's productivity and schedule.

A process used to measure heat output, flow rates, and pressure in geothermal wells. Subcontractors provide specialised testing equipment, instrumentation crews, and data logging services. Work often involves high-temperature conditions requiring specific safety protocols and certified equipment.

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.

A secondary road running parallel to a highway, providing access to adjacent worksites, lease roads, or staging areas. Subcontractors often use frontage roads for heavy equipment moves or crew dispatch without entering main traffic. Confirm load restrictions and municipal permits before routing oversized hauls.

A preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.

A system of buried cables and conduits that delivers power across a site without overhead lines. Subcontractors must locate and verify these lines before any excavation or ground disturbance. Unmarked or mislabelled lines create serious safety and liability risks on job sites.

How Operator Mergers and Acquisitions Affect Your Subcontract Agreements

When operators merge, get acquired, or sell assets, subcontractor agreements are caught in the middle. Learn how M&A activity affects your MSA, payment terms, vendor status, and what to do before, during, and after a deal closes.

How Rig Count Trends Affect Subcontractor Demand and What to Do About It

Rig counts are the earliest signal of where field service work is heading. Learn how to read drilling activity trends, anticipate demand shifts, and position your crew before the phone stops ringing.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
