Well Spacing

A drilling technique that collects formation data in real time as the bit advances. Subcontractors providing LWD services operate specialised downhole tools that transmit data to surface during the drill run. Mobilisation windows are tight, so crews and equipment must be ready on short notice.

A vertical guide structure on a pile-driving or drilling rig that keeps the drill string or pile aligned during penetration. Subcontractors working near this equipment must follow strict exclusion zone protocols. It is also called a mast or leads on some rigs.

A measurable target used to evaluate a subcontractor's performance on safety, productivity, or quality. Clients track KPIs to assess contract compliance and award future work. Common field KPIs include incident rates, on-time mobilisation, and equipment uptime.

An older well built to outdated standards that may require specialised remediation, abandonment, or workover services. Subcontractors should expect non-standard equipment configurations and additional compliance requirements. Scope creep and unforeseen costs are common on legacy well projects.

The number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.

An existing facility—such as a producing well, pipeline, or plant—being modified, upgraded, or maintained rather than built from scratch. For subcontractors, brownfield work often means tighter workspaces, live equipment hazards, and stricter site access requirements. Scopes can change quickly due to unforeseen conditions uncovered during work.

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.
