Well Lifecycle

The computational reworking of existing 3D seismic survey data to improve subsurface imaging using updated algorithms. For subcontractors, it signals potential new data acquisition contracts as operators reassess drilling targets. It rarely requires field crews but can trigger follow-up geophysical or drilling programmes.

The percentage of resource revenue an operator pays to the Crown or landowner before profits are calculated. High royalty rates can reduce operator budgets, directly affecting subcontractor hiring and field service spending. Understanding local royalty structures helps subcontractors anticipate project volumes and client cash flow.

Drilling wells at increasing distances from a proven discovery to test the boundaries of a reservoir. For subcontractors, it signals extended mobilisation cycles and potential new work corridors. Expect shifting logistics, camp requirements, and crew rotations as operators push further from existing infrastructure.

Refers to the contiguous United States, excluding Alaska and Hawaii. For subcontractors, it defines a common work jurisdiction with distinct regulatory, tax, and labour rules from Canadian or Alaskan operations. Mobilisation costs and compliance requirements differ significantly when crews cross into or out of this region.

The horizontal distance drilled from the kickoff point to the end of a wellbore, typically measured in metres. Longer laterals mean more stages, more equipment, and extended crew time on location. Subcontractors should factor lateral length into job costing and resource planning.

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds, pipelines, and structural components for defects. It produces detailed cross-sectional images without cutting or damaging the material. Subcontractors offering PAUT services typically require certified Level II or III technicians and specialised portable equipment.

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.
