A temporary heating system using fluid-filled coils laid on the ground to thaw frozen soil or maintain process temperatures. Subcontractors are often hired to install, monitor, and remove these systems during cold-weather operations. Common in northern pipeline and facility projects where ground conditions affect construction timelines.

Oilsands
IndustryBitumen-rich deposits in northern Alberta requiring large-scale extraction and upgrading operations. For subcontractors, oilsands projects involve extended scopes, remote site conditions, and strict client safety programmes. Work is typically tied to major operators like Suncor, CNRL, or Imperial Oil.
Nearshore Abandonment
IndustryThe decommissioning of wells, pipelines, or infrastructure located in shallow coastal waters. Subcontractors typically handle diving operations, cutting, capping, and seabed remediation work. Regulatory requirements are strict, so current certifications and environmental compliance documentation are essential before mobilising.
High-Impact Well
IndustryA well with significant technical complexity, cost, or strategic value to the operator. For subcontractors, these projects typically involve stricter oversight, specialised equipment, and higher performance expectations. Mobilisation windows and crew qualifications are often scrutinised more closely.
Fired Heater
IndustryA combustion-based unit that uses burners to heat process fluids in oil and gas facilities. Subcontractors are often called in for inspection, refractory work, burner maintenance, and turnaround servicing. Hot work permits and confined space protocols typically apply.
Infrared Thermography
IndustryA non-destructive inspection method using thermal imaging cameras to detect heat anomalies in electrical systems, pipelines, and mechanical equipment. Subcontractors use it to identify failing components before breakdowns occur. Many clients require certified IR (Infrared) thermography reports as part of preventive maintenance scopes.
Wellbore Cleanout
IndustryA downhole operation to remove debris, scale, cement, or fill from inside a wellbore. Subcontractors typically provide coiled tubing, fluid pumping, or snubbing crews for this work. Scope can expand quickly, so confirm day-rate terms and standby provisions before mobilising.
