Ballast

The base material or surface that a coating, lining, or treatment is applied to, such as steel pipe, concrete, or wood. Subcontractors must assess substrate condition before starting surface prep or application work. Poor substrate quality can affect adhesion, warranty, and job acceptance.

A centralised facility or region where hydrogen is produced, stored, and distributed at scale. For subcontractors, these projects generate long-term work in pipefitting, instrumentation, and equipment installation. Expect strict safety certifications and specialised trade requirements on site.

An advanced non-destructive testing method that uses multiple ultrasonic beams to inspect welds and materials for defects. It replaces traditional radiography on many pipeline and pressure vessel jobs. Subcontractors offering PAUT services often command higher rates and qualify for more specialised scopes.

A secondary oil recovery method where water is injected into a reservoir to maintain pressure and push oil toward production wells. Subcontractors support injection well drilling, pump installation, pipeline tie-ins, and ongoing facility maintenance. Scopes are often long-term, requiring sustained crew availability and specialised equipment.

A trenchless pipe rehabilitation method where a resin-saturated liner is turned inside-out into an existing pipe using water or air pressure. The liner cures in place, forming a new pipe within the old one. Subcontractors are typically scoped for setup, inversion equipment operation, and post-cure inspection.

A one-way valve or flap gate that allows water to drain freely but prevents backflow from rising tides or high water levels. Subcontractors working on coastal or waterfront sites must account for tide gate locations when planning drainage, excavation, or utility work. Ignoring these structures can cause flooding, schedule delays, and scope changes.

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.
