CCGT (Combined-cycle Gas Turbine)

A written commitment from a client indicating they plan to award a subcontractor a contract. It allows work or mobilisation to begin before the formal contract is signed. LOIs are not always legally binding, so subcontractors should clarify payment obligations before proceeding.

Systems that use compressed air or gas to power tools, actuators, and control valves on job sites. Subcontractors working with pneumatic equipment must ensure proper pressure ratings and fittings are maintained. Common in instrumentation, pipeline, and heavy construction scopes.

A contractually obligated set of activities and expenditures an operator must complete within a set timeframe, typically tied to a licence or lease agreement; for subcontractors, this creates predictable scopes of work and mobilisation opportunities as operators must execute these commitments or risk losing their rights to the asset.

Expedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.

A compression system that captures hydrocarbon vapours from storage tanks or production equipment instead of venting them. Subcontractors are often hired to install, maintain, or service VRUs to meet emissions regulations. Familiarity with VRU work is increasingly required on oil and gas production sites.

The process of mapping and analysing an underground reservoir's size, rock properties, and fluid content. Subcontractors use this data to understand scope for drilling, completions, and intervention work. It directly influences crew requirements, equipment specs, and contract duration.

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.
