The planning phase before field work begins, covering scope review, site assessments, and schedule alignment with the GC. Subcontractors are often engaged during this phase to provide pricing, labour forecasts, and constructability input. Early involvement can improve mobilisation timelines and reduce costly scope changes later.
Preconstruction
Related Terms
Co2 Storage (carbon Dioxide Storage)
IndustryThe permanent underground injection of captured CO2 into geological formations like depleted reservoirs or saline aquifers. Subcontractors may support well preparation, pipeline installation, monitoring equipment, and injection operations. Demand for specialised field crews is growing as carbon capture projects expand across Canada.
Legacy Well
IndustryAn older well built to outdated standards that may require specialised remediation, abandonment, or workover services. Subcontractors should expect non-standard equipment configurations and additional compliance requirements. Scope creep and unforeseen costs are common on legacy well projects.
Upstream Tie-in
IndustryA connection point where new pipeline or equipment is integrated into an existing live system closer to the wellhead or source. For subcontractors, this work typically requires strict hot-work permits and precise scheduling around production shutdowns. Delays at tie-in points directly impact your crew's standby time and invoice milestones.
Modular Electrical Systems
IndustryPre-engineered electrical units that can be rapidly deployed, reconfigured, or relocated across job sites. Subcontractors often supply or install these systems on short-term contracts. They reduce setup time and support faster mobilisation in remote or temporary work environments.
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.
Paying Quantities
IndustryA legal threshold where a well produces enough oil or gas to justify continued operations and generate profit. For subcontractors, it determines whether a site stays active and whether ongoing service contracts remain in force. Loss of paying quantities can trigger contract suspension or early termination clauses.
