SWD (Saltwater Disposal)

A major U.S. federal law passed in 2021 that funds roads, bridges, pipelines, and energy infrastructure projects. It drives significant contract opportunities for subcontractors in civil, pipeline, and utility work. Prevailing wage and Buy America requirements often apply, affecting labour costs and material sourcing.

A drilling schedule where wells are spaced consecutively with minimal downtime between completions. For subcontractors, it means sustained mobilisation of crews and equipment across multiple well sites. Expect extended contract durations but also compressed turnaround times between locations.

The process of collecting and storing CO2 emissions from industrial sites before they reach the atmosphere. For subcontractors, it means growing work opportunities in facility retrofits, pipeline installation, and compression equipment servicing. Familiarity with CCS (Carbon Capture and Storage) infrastructure is increasingly expected on energy transition projects.

Equipment or materials requiring extended procurement timelines, often months ahead of project start. Subcontractors must identify these early to avoid costly schedule delays. Late orders can stall mobilisation and trigger liquidated damages clauses.

An ownership stake in an oil and gas lease that obligates the holder to pay a share of exploration and production costs. For subcontractors, knowing who holds working interest helps identify who is ultimately responsible for approving work orders and invoices. Operators typically hold majority working interest and are your primary point of contract.

A bearing that uses rolling elements — balls or rollers — to reduce friction between moving parts. Common in pumps, motors, and rotating equipment on job sites. Subcontractors should inspect and replace these during scheduled maintenance to avoid unplanned downtime.
