Combined-Cycle

A method of planning services, maintenance, or contracts around the full lifespan of an asset or project phase. Subcontractors use it to align scopes of work, pricing, and resource deployment from mobilisation through decommissioning. This helps avoid scope gaps and supports longer-term service agreements.

The planned order in which tasks or scopes are completed on a job site. Subcontractors rely on sequencing to schedule crews, avoid downtime, and coordinate with other trades. Delays in sequencing often trigger cascading cost and scheduling impacts.

A tie-in point where two or more pipelines are joined to allow fluid or gas transfer between systems. Subcontractors are often mobilised for the hot-tap, welding, and pressure-testing work at these connections. Scope can expand quickly, so confirm tie-in specifications before pricing the job.

A single end-to-end processing unit that cools natural gas into liquid form for storage and export. Large LNG facilities run multiple trains, each requiring dedicated construction, maintenance, and shutdown crews. Subcontractors are typically mobilised per train, making scope and schedule highly compartmentalised.

A large underground region containing significant natural gas reserves, typically supporting multiple wells and facilities. For subcontractors, basins define key work corridors where long-term service demand is concentrated. Knowing active basins helps crews and companies target mobilisation and contract opportunities.

A preliminary document outlining the key commercial terms agreed between parties before a formal contract is finalised. For subcontractors, it signals serious intent but is not always legally binding. Avoid mobilising crews or purchasing materials based solely on an HoA.

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.
