Legacy Well

A scheduled out-of-water inspection and refit that extends a vessel's certified operational life beyond its original design limit. For subcontractors, it signals a concentrated burst of multi-trade work including hull repairs, coating, and systems upgrades. Scopes are often fast-tracked, creating strong short-term demand for specialised labour and materials.

The estimated volume of oil or gas that can be economically extracted from a reservoir. Higher recoverable reserves typically signal longer project lifespans and sustained demand for field services. Subcontractors use this data to assess contract stability and mobilisation planning.

A regulated initiative requiring operators to decommission and remediate inactive wells, pipelines, or facilities. For subcontractors, it generates scopes in casing removal, site reclamation, and environmental cleanup. Work is often provincially mandated, creating steady contract opportunities outside normal production cycles.

Two parallel horizontal wells — one injector, one producer — used together in SAGD (Steam Assisted Gravity Drainage) operations. Subcontractors are typically mobilised to service both wells as a single scope. Expect coordinated drilling, completions, and maintenance schedules across both wellbores.

The point when physical site work starts, triggering contract milestones, mobilisation schedules, and billing periods for subcontractors. It typically marks when crews, equipment, and materials must be on-site and ready. Delays to this date directly affect subcontractor cash flow and resource planning.

A formal document a subcontractor submits to a prime contractor or operator to express intent to bid on upcoming work. It is not a binding commitment, but helps secure a spot in the tender process. Common in pre-qualification stages for large oilfield or construction scopes.

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.
