Industry Glossary Term

LNTP (Limited Notice To Proceed)

A partial greenlight from a client authorising subcontractors to begin limited, specific work before the full contract is executed. It typically covers early mobilisation, procurement, or site prep activities only. Scope and spending are strictly capped, so track your costs carefully to avoid unauthorised overruns.

Related Terms

Geosteering

Industry

The real-time technique of guiding a drill bit through a target formation using geological data. Subcontractors supporting drilling operations may be called in on short notice as geosteering decisions change well paths. Expect scope adjustments and rapid crew or equipment mobilisation when geosteering is active.

Interoperability

Industry

The ability of different software systems, tools, or equipment to work together without manual workarounds. For subcontractors, this means your timesheets, invoicing, and reporting tools can connect directly with a prime contractor's systems. It reduces double-entry errors and speeds up approvals and payments.

Co2 Storage (carbon Dioxide Storage)

Industry

The 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.

Cryogenic Processing

Industry

A method of separating natural gas into valuable components by cooling it to extremely low temperatures. Subcontractors may be required to hold specialised certifications and use cryogenic-rated equipment on these sites. Strict handling protocols apply, as cryogenic materials pose serious safety risks to field crews.

Instrumentation Upgrades

Industry

Replacement or modernisation of sensors, transmitters, and control devices on existing facilities. For subcontractors, this work is often scoped as short-duration projects requiring certified instrumentation technicians. Tight commissioning deadlines and client-supplied materials are common on these jobs.

Deep Foundation

Industry

A structural support system that transfers building loads to stable soil or rock far below the surface, typically using piles or caissons. Subcontractors are often mobilised for drilling, pile driving, or concrete work on these scopes. Expect specialised equipment requirements and strict geotechnical inspection protocols on site.
