SAGD (Steam Assisted Gravity Drainage)

A method of pumping treated seawater into a reservoir to maintain pressure and improve oil recovery. Subcontractors often support this through pump installation, pipeline work, and water treatment system maintenance. Work typically requires offshore certifications and familiarity with corrosion-resistant materials.

A single end-to-end processing unit that cools natural gas into liquid form for storage and export. Large LNG facilities run multiple trains, each requiring dedicated construction, maintenance, and shutdown crews. Subcontractors are typically mobilised per train, making scope and schedule highly compartmentalised.

Equipment and processes used to identify fluid or gas escapes in pipelines, tanks, or wellheads. Subcontractors are often hired to install, inspect, or maintain these systems under strict regulatory timelines. Failing to meet operator specs can trigger contract penalties or work stoppages.

A series of vessels and equipment that separates wellhead fluids into oil, gas, and water. Subcontractors are often scoped to one train at a time, so know which train your work order covers. Shutdowns or upsets on your train can directly affect your crew's schedule and completion milestones.

A formal notice from an operator or prime contractor inviting subcontractors to express interest in upcoming work. It is not a binding tender but helps owners build a qualified vendor list. Responding early can position your company for the actual bid process.

A well that has been drilled but is awaiting completion work such as fracturing, perforating, or production tie-in. Operators stockpile DUCs when commodity prices are low, then activate them when prices recover. For subcontractors, a large DUC inventory signals upcoming bursts of completion and surface work.

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.
