Progressive Design-Build

A reserve volume of gas kept in an underground storage facility to maintain pressure and operability. For subcontractors, it affects seasonal work demand and mobilisation schedules near storage sites. Operators draw on or inject gas depending on market conditions, driving fluctuating service needs.

A separation process that uses water to sort and classify aggregates, drilling cuttings, or granular materials by size. Subcontractors operate wet screening equipment on site to remove fines and contaminants from bulk materials. It is common in civil construction, pipeline work, and drilling waste management scopes.

A collaborative agreement where owners, contractors, and subcontractors share project risks and rewards under a no-blame framework. Subcontractors may receive performance bonuses but also absorb a portion of cost overruns. Transparency in costs and open-book accounting are typically required.

Refers to offshore oil and gas operations conducted in water depths exceeding 300 metres, where subcontractors and field service crews must hold specialised certifications, work within stricter regulatory frameworks, and often face extended mobilisation timelines and higher equipment day-rates.

A well drilled after a discovery to confirm the size and viability of a reservoir. For subcontractors, appraisal programmes signal short-term scopes before a full development decision is made. Mobilisation windows are often tight and contracts may be limited to single-well terms.

A confidential tender submission where subcontractors submit pricing without knowing competitors' rates. All bids are opened simultaneously by the hiring company. This process is common in public sector and large operator contracts across oil and gas and construction.

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.
