FSU (Floating Storage Unit)

A natural clay mineral used in drilling fluids to stabilise boreholes and suspend drill cuttings. Subcontractors handling bentonite slurry must follow site-specific mixing and disposal procedures. Improper handling can trigger environmental compliance issues and project delays.

A delivery model where a construction manager guarantees a maximum project cost and takes on financial risk if it's exceeded. Subcontractors are hired by the CM, not the owner, making the CM your direct client and contract holder. Your scope, payments, and change orders all flow through the CM.

An existing facility or infrastructure that is being modified, expanded, or recommissioned rather than built from scratch. Subcontractors should expect tighter work windows, live-equipment hazards, and strict permit-to-work requirements. Scheduling and coordination with ongoing operations are critical on brownfield projects.

Crushed stone, gravel, and sand used as base materials in construction and oil and gas site preparation. Subcontractors sourcing or hauling aggregates must account for material costs, transport, and site access conditions. Pricing and availability vary significantly by region and project remoteness.

Drilling rigs specifically configured to drill natural gas wells, requiring crews and equipment rated for high-pressure gas formations. For subcontractors, gas rigs often demand specialised certifications and H2S training. Work volumes typically follow natural gas commodity prices and seasonal heating demand.

A category of ongoing field service work covering routine inspections, preventive maintenance, and corrective repairs on infrastructure or equipment, often awarded to subcontractors through standing agreements or blanket contracts. For field service companies, IMR scopes provide a reliable stream of recurring work but typically require crews to mobilise quickly and hold multiple trade certifications to meet operator requirements.

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.
