Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Critical Minerals

Minerals deemed essential to national economies and energy transition, such as lithium, cobalt, and rare earths. Extraction and processing projects for these materials are driving significant new field service demand across Canada. Subcontractors with mining or remote site experience are well-positioned to pursue this growing work.

Related Terms

Production Shut-in

Industry

A temporary halt to oil or gas production at a well or facility, ordered by the operator. For subcontractors, this often means suspended work orders and delayed revenue until operations resume. Standby rates and demobilisation terms in your contract become critical during a shut-in.

Crane Mats

Industry

Large interlocked timber or composite panels placed under crane outriggers to distribute load on soft or unstable ground. Subcontractors often supply, transport, and install them as part of site prep scopes. Rental and mobilisation costs should be clearly itemised in your quote.

Frac Fleet

Industry

A complete set of hydraulic fracturing equipment deployed together at a well site, including pumps, blenders, and support units. For subcontractors, a frac fleet mobilisation often triggers large, time-sensitive labour and equipment contracts. Knowing fleet size helps you scope crew requirements and forecast workload duration.

E&I (Electrical and Instrumentation)

Industry

A trade discipline covering the installation, maintenance, and commissioning of electrical systems and process instrumentation on industrial sites. Subcontractors in this scope typically hold specialised certifications and work across upstream, midstream, and construction projects. E&I scopes are commonly tendered separately from mechanical or civil work.

Lean Construction

Industry

A project delivery approach that eliminates wasted time, materials, and labour on job sites. Subcontractors use lean methods to tighten scheduling, reduce idle crew time, and improve handoffs between trades. It often involves short-interval planning tools like the Last Planner System.

WCS (Western Canadian Select)

Industry

WCS is the benchmark price for Alberta heavy oil blends sold at Hardisty, Alberta. When WCS prices drop, upstream operators cut budgets, directly reducing subcontractor work volumes and day rates. Monitoring WCS helps field service companies anticipate slowdowns and plan workforce levels accordingly.
