Steel pipe installed in a wellbore to provide structural integrity and prevent contamination between different geological formations, requiring specialized installation and cementing services that subcontractors frequently provide during drilling operations.

Related Terms
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.
Ngl (natural Gas Liquid) Fractionator
IndustryA processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.
Prospective Interval
IndustryA rock formation believed to contain oil or gas, targeted for drilling or evaluation. Subcontractors are often mobilised to support exploration work within these zones. Scope and duration of field service contracts may depend on how many prospective intervals a well will test.
Netback
IndustryThe revenue a producer receives per unit after deducting transportation, processing, and royalty costs. Subcontractors use it as a gauge of operator profitability and budget health. Rising netbacks often signal more field activity and stronger contract opportunities.
2d/3d Seismic Survey
IndustryA geophysical mapping operation that uses sound waves to image underground formations before drilling begins. Subcontractors are hired to deploy geophones, vibroseis trucks, or marine streamers across large survey grids. Work is often remote and time-sensitive, with crews mobilising quickly once permits are secured.
Cathodic Protection
IndustryA corrosion control method that uses electrical current to protect buried or submerged metal infrastructure like pipelines and tanks. Subcontractors installing or maintaining CP (Cathodic Protection) systems must hold recognised certifications. Inspections and anode replacements are common billable scopes in pipeline integrity contracts.
