Hydrocyclone

A measure of a well's or facility's daily oil output. Higher BPD typically means greater activity levels, more crews on site, and increased service demand. Subcontractors often see scope and call-out frequency tied directly to a client's BPD targets.

A processing facility that separates mixed natural gas liquids into individual products like propane, butane, and ethane. Subcontractors often work these sites for maintenance, turnarounds, and equipment servicing. Fractionators operate continuously, so field crews should expect shift-based schedules and strict hot-work permitting.

A facility where oil, gas, or LNG is transferred from pipelines or storage for shipment to buyers. Subcontractors are often mobilised here for maintenance, inspection, and commissioning work. Security clearances and site-specific safety certifications are typically required.

Contracting arrangements beyond traditional lump-sum or day-rate structures, such as alliance, integrated project delivery, or performance-based contracts. These models shift how subcontractors are engaged, paid, and held accountable for outcomes. Understanding them helps field service firms assess risk, pricing strategy, and scope responsibilities before signing.

A globally traded North Sea oil benchmark used to set crude pricing contracts. When Brent prices rise or fall sharply, operators often adjust project budgets, affecting subcontractor work volumes and day rates. Monitoring Brent helps field service companies anticipate slowdowns or ramp-ups in awarded work.

Refers to offshore oil and gas operations conducted in water depths exceeding 300 metres, where subcontractors and field service crews must hold specialised certifications, work within stricter regulatory frameworks, and often face extended mobilisation timelines and higher equipment day-rates.
