The section of casing or liner that has been shot through with charges to allow hydrocarbons to flow into the wellbore. Subcontractors working completions or workovers need to know the perforated interval to plan fluid placement and tool runs accurately.
Perforated Interval
Related Terms
Long-Lead Items
IndustryEquipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.
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.
Energy Transition
IndustryThe global shift from fossil fuels toward renewables, hydrogen, and lower-emission energy sources. For subcontractors, it means new project types, updated certification requirements, and evolving client scopes. Diversifying skills into solar, wind, or carbon capture work helps firms stay competitive.
Stimulation
IndustryWell stimulation refers to treatments like hydraulic fracturing or acid jobs that improve reservoir flow. Subcontractors often mobilise for short, intensive campaigns requiring specialised crews and equipment. Scope changes and standby time are common, so clear contract terms matter.
Drill-And-Blast
IndustryA ground excavation method where holes are drilled into rock, then loaded with explosives and detonated. Subcontractors on these scopes typically require certified blasters and strict compliance with provincial explosives regulations. Expect tight sequencing with other trades and potential site shutdowns during blast windows.
Sanctioned Project
IndustryA project that has received formal capital approval from an operator or owner company and is cleared to proceed. For subcontractors, sanction signals that contracts, purchase orders, and mobilisation timelines are imminent. It marks the point where bidding activity converts into confirmed field work.
