ROV (Remotely Operated Vehicle)

Portable, stackable tank systems used on remote job sites to store potable, process, or wastewater. Subcontractors deploy them quickly without permanent infrastructure. Common on pipeline, camp, and frac support contracts.

A secondary compressor used to increase gas pressure in pipelines or processing systems when inlet pressure is too low. Subcontractors are often hired to install, operate, or maintain these units on short-term field assignments. Rental and service contracts for booster compressors are common in late-life field operations.

The construction and assembly of the above-water structures on offshore platforms, including decks, modules, and processing equipment, where subcontractors are typically engaged for specialised trades such as structural welding, pipefitting, electrical, and instrumentation work. For field service companies, topside scopes often involve strict offshore safety certifications, remote logistics, and milestone-based billing tied to fabrication progress.

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

The collection of drilling tools and equipment at the bottom of the drill string, including the drill bit, drill collars, stabilizers, and downhole motors. For drilling subcontractors, BHA configuration directly impacts drilling performance, tool wear rates, and operational efficiency.

Exploration activity conducted in remote, undeveloped, or previously unworked regions where subcontractors can expect longer mobilisation lead times, higher logistical costs, and limited access to local supply chains or support infrastructure.

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.
