Working Interest

A surface preparation method that uses high-pressure propelled media (sand, steel grit, or slag) to clean and profile metal surfaces before coating or painting. Subcontractors performing this work typically require specialised equipment, trained operators, and site-specific permits. It is common in pipeline, vessel, and structural steel maintenance scopes.

Subsurface saltwater containing dissolved lithium, extracted from formations during drilling or dedicated mining operations. Subcontractors may encounter it on fluid handling, well servicing, or evaporation pond construction contracts. Demand for lithium is driving new project activity across western Canada and the Prairies.

A belt conveyor mounted on a wheeled chassis that pivots in an arc to distribute bulk materials across a wide stockpile area. Subcontractors use them on aggregate, sand, and gravel sites to manage material placement without constant repositioning. They reduce manual labour and speed up site operations significantly.

Chemical additives used in oil and gas processing to separate water from crude oil in production streams. Subcontractors handling fluid management or chemical injection skids are often responsible for their application and dosing. Proper handling requires WHMIS (Workplace Hazardous Materials Information System) compliance and PPE protocols.

The process of pumping produced water or other fluid waste deep into underground formations for disposal. Subcontractors operating injection pumps or wellbore equipment must meet strict provincial and federal disposal regulations. Work often requires specialised well integrity certifications and detailed fluid volume reporting.

An older facility or work location operating on outdated infrastructure, systems, or equipment. Subcontractors often face non-standard conditions, ageing assets, and extra compliance requirements on these sites. Mobilisation and scoping costs can be higher due to undocumented or deteriorated site conditions.

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.

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.
