A contract where the subcontractor delivers a fully completed scope for a fixed price, assuming all cost and schedule risk. The client pays only upon project completion, not for time or materials spent. This model demands tight cost control, as overruns come directly out of your margin.

Remediation
IndustryThe cleanup and restoration of contaminated soil, water, or sites to meet regulatory standards. Subcontractors are often hired specifically for remediation scopes on legacy sites or post-incident cleanup. Work is heavily documented and subject to environmental compliance sign-off.
Contingent Resources
IndustryHydrocarbons discovered but not yet approved for development due to technical or commercial barriers. For subcontractors, these projects exist in planning stages but carry no guaranteed work orders. Mobilisation timelines remain uncertain until operator sanction is confirmed.
Abandonment
IndustryThe regulated process of permanently closing a well or facility at end-of-life. Subcontractors are often hired for plugging, reclamation, and site cleanup scopes. Abandonment projects can be steady work but require strict compliance with provincial regulations.
ILI (In-line Inspection)
IndustryA pipeline integrity assessment using instrumented tools (smart pigs) run through the line to detect corrosion, cracks, or defects. Subcontractors are often mobilised for pig launching, data collection, and follow-up dig verification work. ILI campaigns can drive significant short-notice field service demand.
Abandoned Works Program
IndustryA regulated initiative requiring operators to decommission and remediate inactive wells, pipelines, or facilities. For subcontractors, it generates scopes in casing removal, site reclamation, and environmental cleanup. Work is often provincially mandated, creating steady contract opportunities outside normal production cycles.
Coiled Tubing
IndustryA continuous steel tube wound on a large reel, deployed downhole for well interventions, cleanouts, and stimulation work. Subcontractors often support CT operations as part of completions or well servicing scopes. Specialised CT crews and equipment typically require separate mobilisation planning and rate structures.
