FLNG (Floating Lng Unit)

A contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.

A network of pipelines, compressors, and facilities that collect hydrocarbons from wellheads and move them to processing points. Subcontractors frequently support construction, inspection, and maintenance work across these systems. Scopes can span remote multi-well pads, requiring strong logistics and crew coordination.

A real-time method of mixing gases at the wellsite to meet specific downhole pressure and composition requirements. Subcontractors operating blending equipment must hold current pressure vessel and gas handling certifications. Accurate blending logs are critical for compliance audits and client invoicing.

The available pipeline, trucking, or rail infrastructure to move produced oil, gas, or water away from a wellsite or facility. When takeaway capacity is constrained, operators may shut in wells or delay projects, directly reducing field service work volumes. Subcontractors should monitor regional takeaway conditions as they signal upcoming slowdowns or surges in activity.

A bearing that uses rolling elements — balls or rollers — to reduce friction between moving parts. Common in pumps, motors, and rotating equipment on job sites. Subcontractors should inspect and replace these during scheduled maintenance to avoid unplanned downtime.

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.

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.
