Industry Glossary Term

Bakken Play

A 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.

Related Terms

Q&T (Quench and Tempering)

Industry

A two-stage heat treatment process that hardens steel pipe and structural components used in oil and gas and construction applications. The steel is rapidly cooled (quenched), then reheated (tempered) to improve toughness and reduce brittleness. Subcontractors working with Q&T-rated steel must follow strict welding procedures, as improper heat input can compromise the material's mechanical properties.

Dual-Class Share Structure

Industry

A corporate ownership arrangement where founders or executives hold shares with greater voting power than ordinary investors. For subcontractors, this means a client company's leadership can make major operational decisions without shareholder approval. Expect stable long-term contracts but limited outside pressure to change payment terms or procurement practices.

Caustic Service

Industry

Work involving equipment or piping that handles highly alkaline chemicals, such as sodium hydroxide. Subcontractors must use compatible materials and certified personnel to avoid rapid corrosion and serious chemical burns. Specialised PPE and handling procedures are typically required by the client's safety plan.

Tolerance Zone

Industry

The acceptable range of variation allowed in measurements, materials, or workmanship on a job site. Subcontractors must stay within these limits or face rework orders and cost penalties. Specs are set by the prime contractor or engineering drawings.

MOU (Memorandum of Understanding)

Industry

A non-binding agreement outlining the intent to work together before a formal contract is signed. Subcontractors use MOUs to secure preferred vendor status or reserve capacity for upcoming projects. They carry no payment guarantee, so avoid mobilising resources based solely on an MOU.

Telematics

Industry

A system that tracks vehicle and equipment location, usage, and performance data in real time. Subcontractors use it to monitor fleet activity, verify hours worked, and support billing accuracy. It also aids compliance with safety and maintenance requirements.
