Energy Transition

A sealed system that transfers heat between two fluid circuits without them making direct contact. Subcontractors service these units for cleaning, inspection, and pressure testing. They are common in oilfield facilities, compressor stations, and industrial construction sites.

A mobile conveyor system that extends in length and swings in an arc to stockpile bulk materials across a wide area. Commonly used on pipeline, mining, and civil construction sites for aggregate, gravel, or spoil management. Subcontractors operating this equipment typically require certified operators and may be responsible for setup, teardown, and repositioning.

A well drilled in an unproven or lightly tested area to determine whether hydrocarbons are present, often representing shorter-term, high-mobilisation contracts for subcontractors with less predictable follow-on work than development drilling programmes.

The sector of companies and subcontractors that provide specialised labour, equipment, and technical services to oil and gas operators. This includes drilling, completions, maintenance, and production support work. Most field subcontractors operate within the OFS sector, working under Tier 1 service companies or directly for operators.

Systems that capture and hold power (batteries, flywheels, capacitors) for later use on remote or off-grid job sites. Subcontractors use them to reduce generator runtime and fuel costs. They are increasingly specified by clients in ESG-driven scopes.

A type of subsurface rock layer—primarily limestone or dolomite—that subcontractors may encounter during drilling, completions, or civil excavation work, often requiring specialised equipment, bit selections, or modified drilling programmes due to its hardness and tendency to cause lost circulation events.

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.
