CCUS (Carbon Capture, Utilization, and Storage)

The process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.

A controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.

The detailed engineering phase before a project is sanctioned for full construction. For subcontractors, FEED signals that scopes, specs, and vendor lists are being finalised. Winning work during FEED often positions your company for contracts in the execution phase.

A coastal or estuary facility where bulk commodities like LNG or crude oil are loaded onto marine vessels for export. Water depth fluctuates with tides, affecting vessel scheduling and your crew's access windows. Subcontractors must plan shifts and equipment mobilisation around tide tables and vessel berthing schedules.

A service job focused on removing debris, scale, or obstructions from a wellbore, tank, or pipeline. Subcontractors are often mobilised on short notice to perform cleanouts between production phases. Accurate job scoping is critical, as unforeseen material volumes can affect your quoted price.

A cone-shaped separation device that removes solids or liquids from drilling fluids using centrifugal force. Subcontractors service and maintain these units on drilling rigs and fluid processing systems. Proper handling requires familiarity with high-pressure fluid systems and waste disposal regulations.

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.
