Daily oil & gas and construction news for subcontractors

IndustryGlossary Term

Subcontractors must clarify ownership rights over derivative goods before work begins. Contracts often assign these rights to the prime contractor or client by default.

Related Terms

Offshore Commissioning

Industry

The process of testing and activating offshore systems and equipment before handover to the operator. For subcontractors, this phase typically requires specialised certifications and offshore survival training. Mobilisation costs and remote logistics significantly affect bid pricing and crew planning.

Development Sanction

Industry

The formal approval by an operator or project owner to proceed with full-scale field development. For subcontractors, it signals that major contracts, mobilisation, and field work are imminent. It marks the point where scopes of work move from planning to active procurement.

LOI (Letter of Intent)

Industry

A written commitment from a client indicating they plan to award a subcontractor a contract. It allows work or mobilisation to begin before the formal contract is signed. LOIs are not always legally binding, so subcontractors should clarify payment obligations before proceeding.

Hot Shot

Industry

Expedited delivery service for equipment, parts, or materials to remote job sites. Often used for urgent oilfield deliveries.

SAGD (Steam Assisted Gravity Drainage)

Industry

A heavy oil extraction method using paired horizontal wells where steam is injected into the upper well to heat bitumen, allowing it to drain by gravity to the lower production well. Creates specialized maintenance and service opportunities for subcontractors in steam generation equipment, wellhead systems, and pipeline infrastructure at oil sands operations.

AFE (Authorization for Expenditure)

Industry

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.
