A method of extracting heavy oil or bitumen by injecting steam underground to heat and mobilise the resource. Common techniques include SAGD (Steam Assisted Gravity Drainage) and CSS (Cyclic Steam Stimulation). Subcontractors support these operations through facility construction, pipefitting, instrumentation, and ongoing maintenance work.

Hot Shot
IndustryExpedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.
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.
Master Service Agreement (MSA)
IndustryA contract between an operator and a service company that establishes the general terms and conditions for all future work. Individual jobs are then executed under work orders or AFEs referencing the MSA.
NPRA (National Petroleum Reserve-alaska)
IndustryA large federally managed area in northwest Alaska open to oil and gas exploration and development. Subcontractors working here face extreme remote logistics, strict federal permitting, and seasonal access windows. Mobilisation costs and compliance requirements are significantly higher than conventional onshore projects.
Vacuum Excavation (vac-Ex)
IndustryA non-destructive digging method that uses high-pressure water or air to loosen soil, then suctions it into a debris tank. Subcontractors use it for safe excavation near buried utilities, pipelines, and cables. It is commonly required on oil and gas sites where mechanical digging poses strike risks.
Shallow-Water
IndustryOffshore operating zones typically under 500 feet of water depth. For subcontractors, these sites use jack-up rigs and barges rather than deepwater vessels. Crew access, equipment requirements, and mobilisation costs differ significantly from deepwater scopes.
