A formal document a subcontractor submits to a prime contractor or operator to express intent to bid on upcoming work. It is not a binding commitment, but helps secure a spot in the tender process. Common in pre-qualification stages for large oilfield or construction scopes.

Bakken Play
IndustryA major tight-oil producing region spanning North Dakota, Montana, and southern Saskatchewan and Manitoba. Subcontractors working here should expect high-volume horizontal drilling and multi-stage fracturing scopes. Seasonal road bans and remote logistics significantly impact crew mobilisation and equipment scheduling.
Equity Partnership (first Nations)
IndustryAn ownership arrangement where a First Nations group holds a financial stake in a project or company. Subcontractors may be required to include an equity partner to win work on certain corridors or project areas. This affects bidding structure, profit-sharing, and how contracts are awarded.
Lower 48
IndustryRefers to the contiguous United States, excluding Alaska and Hawaii. For subcontractors, it defines a common work jurisdiction with distinct regulatory, tax, and labour rules from Canadian or Alaskan operations. Mobilisation costs and compliance requirements differ significantly when crews cross into or out of this region.
Boe/d (barrels of Oil Equivalent Per Day)
IndustryA standard measure of a well site's or facility's total energy output, combining oil, gas, and NGLs into one comparable unit. Operators use BOE/D figures to size projects and determine crew and equipment requirements. Higher BOE/D rates typically signal larger scopes of work and longer service contracts for subcontractors.
LNG (Liquefied Natural Gas)
IndustryNatural gas cooled to -162°C to become liquid for easier transport and storage, creating specialized work opportunities for subcontractors in cryogenic equipment maintenance, pipeline construction, and terminal facilities that require specific safety certifications and cold-weather expertise.
Artificial Lift
IndustryA system used to boost production from oil wells that lack sufficient natural pressure to bring fluids to surface. Common methods include rod pumps, ESPs (Electric Submersible Pumps), and gas lift. Subcontractors are often mobilised to install, service, or troubleshoot these systems throughout a well's producing life.
