Miller Act

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.

A charge issued by an operator or general contractor to a subcontractor for costs incurred due to defective work, delays, or failure to meet contractual obligations.

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.

A formal pricing submission to secure a contract for equipment, vehicles, or workspace on a lease basis. Subcontractors use lease bids to compete for longer-term site access or equipment rental agreements. Winning a lease bid typically locks in your daily or monthly rate for the contract duration.

Materials or equipment stored at your job site but owned by the supplier until you use them. You only pay when items are consumed, reducing upfront capital tied up on remote projects. Common for frequently used consumables like fittings, gaskets, and PPE on long-duration field contracts.

A contract clause allowing the hiring company to end a service agreement before the scheduled completion date. Subcontractors may receive a penalty payment, but it is rarely full contract value. Always clarify demobilisation costs and notice periods before signing.
