The regulated process of permanently sealing and decommissioning a well at end of life. For subcontractors, it generates specialised scope including cementing, wellhead removal, and site reclamation work. Abandonment projects are often time-sensitive due to regulatory deadlines and operator liability pressure.
Well Abandonment
Related Terms
Tunnel Portal
IndustryThe open entrance and exit points of a tunnel where underground meets surface operations. For subcontractors, portals are critical mobilisation zones for equipment, crews, and material staging. Access, congestion, and safety controls at portals directly affect your crew's productivity and schedule.
Pipeline Tie-in
IndustryA pipeline tie-in is the physical connection of a new pipeline section to an existing live system. For subcontractors, tie-in work often requires hot-tap certified crews and strict isolation procedures. Scheduling is critical, as tie-ins typically involve planned shutdowns with tight production windows.
PWHT (Post-weld Heat Treatment)
IndustryA controlled heating and cooling process applied to welds after completion to reduce stress and improve strength. Subcontractors must confirm PWHT requirements before mobilising, as it adds time, equipment, and certified personnel to scope. Failing to price it into your bid can significantly erode job margins.
Bakken Play
IndustryA major tight-oil producing region spanning North Dakota, Montana, and southern Saskatchewan and Manitoba. Subcontractors working here should expect high-volume horizontal drilling and multi-stage fracturing scopes. Seasonal road bans and remote logistics significantly impact crew mobilisation and equipment scheduling.
ISR (In-situ Recovery)
IndustryA mining and extraction method where ore or hydrocarbons are dissolved and pumped to surface without conventional excavation. Subcontractors typically supply specialised drilling, fluid handling, and wellfield construction services. Work scopes are often long-duration with strict environmental monitoring requirements.
Long-Lead Procurement
IndustryThe advance ordering of materials or equipment with lengthy manufacturing or delivery timelines. For subcontractors, delays in these items often push back mobilisation dates and affect project cash flow. Always confirm long-lead delivery schedules before locking in your crew start dates.
