Fumigation (engine)

A crossing where a road, pipeline, or utility passes over or under another route using a bridge or culvert. Subcontractors must account for grade separations when planning equipment moves and material hauls. Permits and escort requirements often apply when loads approach clearance limits.

A mobile offshore drilling rig with retractable legs that jack down to the seabed, elevating the platform above water. Subcontractors mobilising to a jackup must account for offshore certification, marine logistics, and platform-specific access requirements.

A land-based sedimentary region where oil and gas exploration and production activity is concentrated. For subcontractors, basins define your likely work zones, client base, and mobilisation distances. Key Canadian examples include the Western Canada Sedimentary Basin (WCSB).

The segment of the oil and gas industry involved in processing, storing, and transporting oil, gas, and NGLs. Includes pipelines, gathering systems, and processing plants.

Exploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.

A legal right allowing access to land owned by someone else for a specific purpose, such as running pipelines or power lines. Subcontractors must confirm easement boundaries before mobilising equipment or breaking ground. Working outside easement limits can trigger legal liability and project shutdowns.

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.
