VLCC (Very Large Crude Carrier)

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.

Drilling performed on a proven reservoir to extract hydrocarbons commercially, as opposed to exploration work. For subcontractors, it typically means longer campaigns with more predictable scopes. Expect repetitive well programmes and stronger potential for extended service agreements.

The IP Rate measures a well's output immediately after it comes online, typically in barrels or mcf per day. Operators use it to assess well performance, which directly affects how quickly field service contracts ramp up or wind down. A strong IP Rate often signals sustained work volume for subcontractors on site.

A failure mode where metal components crack under the combined effect of tensile stress and corrosive environments. Subcontractors must inspect susceptible equipment — like pipelines, pressure vessels, and lifting gear — for early signs. Missed SCC (Stress-Corrosion Cracking) damage can trigger costly shutdowns, liability claims, or failed inspections.

A method of injecting a secondary fuel, such as natural gas or propane, into a diesel engine's air intake to supplement combustion. It reduces fuel costs and emissions on long-running field equipment. Subcontractors should verify fumigation setups meet emissions compliance requirements in their operating jurisdiction.

A facility that converts high-voltage electrical power to usable levels for a job site or facility. Subcontractors in construction and oil & gas often work in, around, or on behalf of substations. Strict access controls and electrical safety certifications are typically required.

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.
