Substation

A drilling programme where rigs operate continuously at accelerated rates to maximise footage drilled in minimal time. Subcontractors face compressed mobilisation windows, higher equipment wear, and rapid crew rotation demands. Billing cycles and material supply chains must keep pace with the accelerated schedule.

A measure of how consistently a subcontractor completes work within the agreed timeline. Low compliance can trigger penalties, delay progress payments, or affect contract renewal. Tracking it helps field crews identify where mobilisation or scope changes are causing slippage.

A timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.

A detailed list of all materials, quantities, and specifications needed to complete a scope of work. Subcontractors use it to prepare accurate bids and avoid costly shortages or overruns in the field.

The process of defining the boundaries and quantity of an oil, gas, or mineral deposit through appraisal drilling and testing. For subcontractors, it signals a sustained work programme requiring crew, equipment, and logistical planning. Delineation phases often drive multi-month contracts for drilling, completions, and field services.

A mobile conveyor system that extends in length and swings in an arc to stockpile bulk materials across a wide area. Commonly used on pipeline, mining, and civil construction sites for aggregate, gravel, or spoil management. Subcontractors operating this equipment typically require certified operators and may be responsible for setup, teardown, and repositioning.

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.
