LNG (Liquefied Natural Gas)

The evaluation of reservoir rock and fluid properties using well log data and core samples. Results determine whether a well is worth completing, directly affecting drilling programme scope and subcontractor workload. Field crews support this work through wireline logging, coring, and fluid sampling operations.

A system that tracks vehicle and equipment location, usage, and performance data in real time. Subcontractors use it to monitor fleet activity, verify hours worked, and support billing accuracy. It also aids compliance with safety and maintenance requirements.

A filtration process that uses semi-permeable membranes to separate gases or liquids by molecular size or pressure. Common in natural gas processing and produced water treatment on field sites. Subcontractors may install, inspect, or maintain membrane units as part of facility service scopes.

The above-water structure of an offshore platform, including processing equipment, living quarters, and wellheads. Subcontractors working topside must meet strict offshore safety and certification requirements. Scope of work and billing rates often differ significantly from subsea or onshore assignments.

An electronic device that controls motor speed by adjusting electrical frequency, commonly found on pumps, compressors, and fans at oil and gas facilities. Subcontractors working near VFDs must follow strict electrical isolation and lockout/tagout procedures. Technicians servicing VFDs typically require specialised training and may need additional site certifications.

A structural support system that transfers building loads to stable soil or rock far below the surface, typically using piles or caissons. Subcontractors are often mobilised for drilling, pile driving, or concrete work on these scopes. Expect specialised equipment requirements and strict geotechnical inspection protocols on site.

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.
