A small, self-contained power system that operates independently from the main utility grid. Subcontractors working remote sites often rely on microgrids for consistent site power. Knowing the local power setup affects equipment compatibility and fuel logistics planning.
Microgrid
Related Terms
Compression Expansion
IndustryA growth phase where an operator scales up gas compression infrastructure, creating demand for additional field service crews and equipment. Subcontractors should anticipate increased work orders for installation, commissioning, and maintenance. Securing standing agreements before expansion begins helps lock in preferred vendor status.
STACK (Sooner Trend Anadarko Basin Canadian and Kingfisher)
IndustryA prolific multi-zone oil and gas play in central Oklahoma covering Canadian and Kingfisher counties. Subcontractors active here support high-density horizontal drilling and completions work. Mobilisation demand can spike quickly, so maintaining local crew and equipment availability is critical.
EPC (Engineering, Procurement, Construction)
IndustryA project delivery model where one main contractor handles all phases from design to completion, typically creating multiple subcontracting opportunities for field service companies across different project phases. For subcontractors, EPC projects often mean working under a prime contractor who coordinates all trades and manages the overall timeline and specifications.
Predictive Maintenance
IndustryA maintenance approach that uses equipment data and monitoring to forecast failures before they occur. Subcontractors may be dispatched for targeted repairs based on sensor alerts rather than fixed schedules. This reduces emergency callouts and helps crews plan mobilisation more efficiently.
TVD (True Vertical Depth)
IndustryThe straight-line vertical distance from surface to a specific point in a wellbore, regardless of how the well is drilled — subcontractors working on directional or horizontal wells need to reference TVD (not measured depth) when scoping equipment reach, calculating hydrostatic pressures, or verifying work zone depths on service orders.
Well Testing
IndustryA series of controlled flow and pressure measurements performed on a newly drilled or existing well to evaluate its production potential and reservoir characteristics; for subcontractors, this work often involves deploying and operating specialised equipment such as separators, flowback units, and data acquisition systems under tightly scheduled, high-priority conditions.
