The process of running a device called a pig through a pipeline to clean, inspect, or displace fluids. Subcontractors are often hired to provide pig launcher and receiver equipment, operators, and associated support services. Pigging scopes can range from routine maintenance runs to complex inline inspection campaigns.
Pigging
Related Terms
Single-Source Contractor
IndustryA company hired to deliver an entire scope of work, rather than splitting it among multiple subcontractors. For field service subs, this means one firm holds the prime contract and manages all trades underneath. Winning a single-source role improves cash flow and reduces competition, but increases liability exposure.
Pressure Pumping
IndustryA well stimulation service involving the high-pressure injection of fluids — such as fracturing fluid, cement, or acid — into a wellbore to improve production or complete the well; for subcontractors, it represents a specialised, equipment-intensive scope of work that typically requires certified operators, dedicated pump trucks, and close coordination with the primary operator on site.
Reactivation
IndustryThe process of bringing a dormant well, pipeline, or piece of equipment back into active service, often requiring subcontractors to mobilise crews, conduct inspections, and complete compliance checks before full operations can resume. For field service companies, reactivation work can represent a significant surge in contract opportunities, particularly during periods of rising commodity prices.
COR (Certificate of Recognition)
IndustryA voluntary safety certification program in Canada that recognizes employers who have developed health and safety management systems that meet established standards. Required by many operators in Alberta and Western Canada.
BPD (Barrels Per Day)
IndustryA measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.
Spot Work
IndustryShort-term, unplanned jobs awarded without a long-term contract, typically filled on short notice. Subcontractors are engaged for a single scope or site visit at a negotiated day rate. Common in shutdown, turnaround, and emergency maintenance situations.
