A well evaluation process where multiple reservoir intervals are tested separately in a single wellbore operation. Subcontractors must coordinate pressure testing, fluid sampling, and equipment rigging across several zones. Scope changes between zones can affect crew hours, tool rentals, and invoicing significantly.
Multi-Zone Testing
Related Terms
Parcel
IndustryA defined section of land or a lease area assigned to a specific project or operator. Subcontractors may be scoped and mobilised by parcel, affecting billing boundaries and crew deployment zones.
Quick Coupler
IndustryA mechanical fitting that connects hoses, pipes, or hydraulic lines without tools or threading. Common on wellsite and construction equipment, they allow fast swaps between attachments or fluid systems. Subcontractors should verify coupler compatibility before mobilising to avoid costly downtime.
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.
Sealed Bid
IndustryA confidential tender submission where subcontractors submit pricing without knowing competitors' rates. All bids are opened simultaneously by the hiring company. This process is common in public sector and large operator contracts across oil and gas and construction.
Work Order
IndustryA formal document issued by a client or general contractor authorising a subcontractor to perform a specific scope of work. It outlines the job details, location, timeline, and agreed rate. Subcontractors typically cannot invoice without a valid work order number.
Run Schedule
IndustryA timeline that outlines when specific tools, equipment, or crews are deployed downhole or on-site during an operation, dictating when a subcontractor's services are required and for how long. For field service companies, the run schedule directly determines mobilisation timing, crew rotations, and invoiceable hours on location.
