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
Underground Electrical Distribution
IndustryA system of buried cables and conduits that delivers power across a site without overhead lines. Subcontractors must locate and verify these lines before any excavation or ground disturbance. Unmarked or mislabelled lines create serious safety and liability risks on job sites.
Rigging
IndustryThe equipment and techniques used to lift, secure, and move heavy loads on a job site. Subcontractors must ensure all rigging gear is certified and operators are ticketed. Improper rigging is a leading cause of serious incidents and contract liability.
Gas Sales Precedent Agreement
IndustryA conditional agreement between a producer and gas buyer that must be satisfied before a project moves to full development. For subcontractors, it signals that major field mobilisation and long-term work commitments depend on this deal closing. Delays or failed negotiations can stall contracts, procurement, and crew deployment.
AISI (American Iron and Steel Institute)
IndustryA standards body that classifies steel grades used in oilfield and construction equipment. Subcontractors reference AISI codes when sourcing pipe, fittings, or structural steel to meet spec requirements. Knowing these grades helps avoid costly material rejections on site.
Oil-Directed Drilling
IndustryA drilling programme targeting oil reservoirs rather than natural gas. Subcontractors can expect higher rig activity and longer campaign durations in regions where oil prices justify development. Demand for completions, fluid hauling, and wellsite services typically rises during oil-directed cycles.
Debottleneck
IndustryTo identify and remove constraints limiting throughput or efficiency on a project or facility. For subcontractors, this often means mobilising additional crews or equipment to clear backlogs. Work is typically urgent and can command premium rates.
