A 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.
Well Testing
Related Terms
Load Path Planning
IndustryThe process of mapping how heavy equipment or materials will be moved from origin to job site. Subcontractors must identify weight limits, road restrictions, and permit requirements along the route. Poor planning causes costly delays, fines, or equipment damage.
Trenchless
IndustryA method of installing or repairing underground pipelines and conduits without open excavation. Techniques include horizontal directional drilling (HDD) and pipe bursting. Subcontractors working trenchless scopes need specialised equipment and certified operators.
FFS (Fitness-for-service)
IndustryA structured engineering assessment that determines whether ageing or damaged equipment is safe to keep operating. Subcontractors are often hired to collect inspection data, run integrity tests, or execute repairs recommended by FFS evaluations. Understanding FFS scope helps field crews prioritise work orders and meet client fitness thresholds before returning assets to service.
Transmission Planning
IndustryThe long-term process of designing and expanding power grid infrastructure to meet future energy demand. For subcontractors, it drives project pipelines for line construction, right-of-way clearing, and equipment installation. Winning transmission work often requires early engagement with utilities and grid operators.
Wet Utilities
IndustryUnderground systems that carry water, sewage, or other liquids, including water mains, storm drains, and sewer lines. Subcontractors must locate and mark these lines before any excavation to avoid costly damage or work stoppages. Wet utility work often requires specialised crews and municipal permits.
Subsea Architecture
IndustryThe arrangement of underwater equipment — wellheads, flowlines, manifolds, and controls — that connects a seabed well to a surface facility. Subcontractors working in ROV operations, umbilical installation, or inspection services must understand this layout to execute scopes safely. Work packages are often structured around specific architecture components.
