Shale Basin

The full sequence of a well's existence, from drilling and completion through production and eventual abandonment. For subcontractors, each phase represents distinct scopes of work, crew requirements, and contract opportunities. Understanding the lifecycle helps you anticipate project transitions and position for follow-on work.

A drilling technique used to steer a wellbore along a non-vertical path to reach a target zone. Subcontractors supporting these operations often require specialised tooling, MWD (Measurement While Drilling) equipment, and certified directional hands. Scopes can shift quickly, so flexible crew and equipment mobilisation is essential.

The contractual framework that determines how an owner, general contractor, and subcontractors are organised on a project. It directly affects when you get hired, who you report to, and how your scope is defined. Common methods include DBB (Design-Bid-Build), DB (Design-Build), and EPCM (Engineering, Procurement, and Construction Management).

A major tight-oil producing region spanning North Dakota, Montana, and southern Saskatchewan and Manitoba. Subcontractors working here should expect high-volume horizontal drilling and multi-stage fracturing scopes. Seasonal road bans and remote logistics significantly impact crew mobilisation and equipment scheduling.

A temporary or permanent access road built to service an oil and gas lease or well site. Subcontractors are often responsible for maintaining or mobilising equipment over these roads. Road conditions directly affect trucking rates, equipment wear, and scheduling.

A globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.

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.
