MISO (Midcontinent Independent System Operator)

A retaining wall system that uses layers of compacted fill reinforced with geogrid or straps to hold back soil. Common on pipeline corridors, well pad construction, and access road projects. Subcontractors may be scoped for earthworks, backfill compaction, or wall panel installation.

The volume of crude oil a refinery processes over a set period, typically measured in barrels per day. Higher throughput means more maintenance, turnaround, and inspection work for subcontractors. Expect busier scopes and tighter schedules when a client ramps up processing capacity.

A centralised surface facility where oil and gas from multiple wells is gathered, measured, and processed. Subcontractors frequently mobilise to battery sites for maintenance, instrumentation, and civil work. Knowing the battery layout helps crews plan access, logistics, and safe work zones.

A budgeting document used in oil and gas projects that outlines expected costs and seeks approval before work begins. Subcontractors often work under AFEs issued by operators.

A belt conveyor mounted on a wheeled chassis that pivots in an arc to distribute bulk materials across a wide stockpile area. Subcontractors use them on aggregate, sand, and gravel sites to manage material placement without constant repositioning. They reduce manual labour and speed up site operations significantly.

A safety and compliance management system used by some operators to pre-qualify and manage contractors working on their sites.
