LEM (Labour, Equipment, Materials)

A variable fee added to invoices to recover fuel cost fluctuations on equipment-heavy jobs. Subcontractors often tie it to a published index, such as the weekly rack price. Review prime contracts carefully — some owners cap or exclude surcharges entirely.

The process of tracking all costs associated with a specific job or project, including labor, equipment, materials, and overhead. Accurate job costing is essential for understanding profitability.

Revenue that is earned but never collected due to operational inefficiencies. Common causes include lost field tickets, unbilled equipment hours, forgotten third-party charges, and documentation errors. Industry estimates suggest 1-5% of revenue is lost to leakage in paper-based operations.

A standardised daily report documenting rig operations, hours worked, and downtime on a drilling project. Subcontractors often must align their own daily reports with the IADC DDR for invoicing and performance verification. Discrepancies between your records and the DDR can delay payment or trigger billing disputes.

Contracts that lock in a future price for North Sea crude oil, used as a global benchmark. When Brent prices drop, operators often cut budgets and delay projects, directly reducing subcontractor workloads. Tracking Brent futures helps field service companies anticipate slowdowns and plan their crews and bids accordingly.

A pricing model where the contractor bills for actual time spent and materials used, plus markup. Common for work where scope is uncertain.
