A heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.
SAGD (Steam Assisted Gravity Drainage)
Related Terms
Well Program
IndustryA technical document outlining the planned scope, procedures, and specifications for drilling or completing a well. Subcontractors use it to understand required services, equipment, and sequencing before mobilising. It directly affects how you scope work and price your bid.
MISO (Midcontinent Independent System Operator)
IndustryA regional grid operator managing electricity transmission across central North America. Subcontractors working on power infrastructure or energy facilities in MISO territory must align project schedules with its grid access and outage approval processes. Permitting and energisation timelines are often dictated by MISO interconnection queues.
Baseload Energy
IndustryThe minimum level of power demand that a facility or site requires continuously, around the clock. For subcontractors, it determines whether remote worksites need dedicated generators or grid connections. Stable baseload requirements help crews plan equipment fuel consumption and maintenance schedules.
Cementing
IndustryThe process of pumping cement slurry into a wellbore to seal the casing and isolate formation zones. Subcontractors may be hired to provide cementing crews, pumping equipment, or bulk material handling. It is a critical well integrity step with strict regulatory and operator specifications.
In-Situ
IndustryWork performed on-site without removing equipment or materials from their installed position. Subcontractors are often mobilised specifically for in-situ repairs, inspections, or testing. Scope and billing should clearly reflect the fixed work location.
TOFD (Time-of-flight Diffraction)
IndustryAn ultrasonic weld inspection method used to detect and size internal flaws in pipelines and pressure vessels. Subcontractors performing NDT work must hold TOFD-specific certifications to qualify for this scope. It is widely accepted by regulators as an alternative to radiographic testing.
