HDPE (High-density Polyethylene)

Natural gas compressed and stored at high pressure, used to fuel fleet vehicles and equipment on remote job sites. Subcontractors may need CNG-certified technicians and compliant fuelling procedures when working on CNG infrastructure projects or operating CNG-powered equipment.

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.

Refers to oil reservoirs located beneath thick layers of underground salt, typically in deepwater offshore basins. For subcontractors, pre-salt projects involve specialised equipment, extended mobilisation timelines, and higher operational complexity. Expect longer contract cycles and stricter certification requirements from operators.

A critical shipping chokepoint between Oman and Iran controlling roughly 20% of global oil flow. Disruptions here can spike material costs and delay equipment deliveries for subcontractors. Budget contingencies and procurement timelines should account for geopolitical risk in this corridor.

A downhole pump system installed inside a wellbore to lift fluids to surface when natural reservoir pressure is insufficient. Subcontractors are commonly engaged for ESP installation, pulling, and maintenance work. Specialised lifting equipment and electrical certifications are typically required on these jobs.

An area of abnormally high surface temperature detected during infrared inspection of electrical, mechanical, or process equipment. Hotspots often signal failing components, loose connections, or insulation breakdown requiring urgent repair. Subcontractors must document and report findings promptly to avoid liability and costly unplanned shutdowns.

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.
