Turnkey Contract

An existing facility—such as a producing well, pipeline, or plant—being modified, upgraded, or maintained rather than built from scratch. For subcontractors, brownfield work often means tighter workspaces, live equipment hazards, and stricter site access requirements. Scopes can change quickly due to unforeseen conditions uncovered during work.

An expedited approval process for subcontractor submissions such as invoices, change orders, or safety documents. Operators use it when project timelines are compressed or scope changes require urgent sign-off. Subcontractors should flag submissions clearly to qualify for faster processing.

Drilling new wells between existing producers to recover bypassed reserves in a developed field. For subcontractors, it means shorter mobilisation windows and back-to-back well programmes. Expect high crew utilisation but tight scheduling with little downtime between jobs.

The initial release of fluids, sand, and gases from a wellbore after hydraulic fracturing, which requires specialised crews and equipment on-site to manage, separate, and dispose of the returned materials safely. For field service subcontractors, flowback operations represent a distinct scope of work with dedicated mobilisation requirements and often involve tight scheduling windows tied to the operator's completion timeline.

The number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.

The process of moving equipment and personnel to a job site (mobilization) and returning them afterward (demobilization). Often billed as separate line items.

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.
