Design-Build

An arrangement where a primary contractor hires an outside company to perform specialised work on a project. For subcontractors, this defines your position in the contracting chain and affects payment terms, liability, and site access. Knowing your tier level helps clarify who you invoice and who manages your compliance requirements.

The formal point when a drilling rig is demobilised and the operator ends the rig contract. For subcontractors, it signals the close of associated scopes of work and triggers final invoicing. Crew demob, equipment retrieval, and close-out documentation should begin immediately.

A lightweight, corrosion-resistant composite material used in piping, grating, and structural components on oilfield and construction sites. Subcontractors encounter FRP in offshore platforms, chemical plants, and water treatment facilities. It requires specialised handling and cutting procedures to avoid hazardous dust exposure.

A PPCA is a binding agreement signed before subcontractors jointly develop a bid or proposal. It sets rules around cost-sharing, confidentiality, and each party's scope. This protects your pricing and proprietary methods during the teaming process.

Prefabricated, stackable storage units deployed on job sites to house tools, equipment, or materials. Subcontractors use them to reduce mobilisation costs and adapt quickly to changing site layouts. Units can be reconfigured or relocated as project phases shift.

The estimated volume of oil or gas that can be economically extracted from a reservoir. Higher recoverable reserves typically signal longer project lifespans and sustained demand for field services. Subcontractors use this data to assess contract stability and mobilisation planning.

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.
