A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.

Software that centralises a subcontractor's core business functions, including payroll, invoicing, procurement, and scheduling. It replaces disconnected spreadsheets and paper systems with a single source of operational data. Larger GCs and operators may require subcontractors to integrate with their ERP for work orders and payment processing.

Methods for installing or repairing underground pipelines and conduits without open-cut excavation. Common techniques include HDD (Horizontal Directional Drilling) and pipe bursting. Subcontractors specialising in these methods often command premium rates due to reduced surface disruption and specialised equipment requirements.

A method of separating natural gas into valuable components by cooling it to extremely low temperatures. Subcontractors may be required to hold specialised certifications and use cryogenic-rated equipment on these sites. Strict handling protocols apply, as cryogenic materials pose serious safety risks to field crews.

A structural tower erected over a mine shaft to support hoisting equipment and guide cables. Subcontractors working near headframes must coordinate lifts and personnel movement carefully. Access restrictions and load limits are strictly enforced on-site.

A fixed surface facility where oil, gas, and water from multiple wells are separated, treated, and prepared for transport or sale. For subcontractors, a CPF is often a long-term, high-activity work site requiring trades, maintenance, and operations crews. Scope can include initial construction, commissioning, turnarounds, and ongoing maintenance contracts.

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.
