Drillship
Related Terms
AFE (Authorization for Expenditure)
IndustryA 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.
Hydrogen Hub
IndustryA centralised facility or region where hydrogen is produced, stored, and distributed at scale. For subcontractors, these projects generate long-term work in pipefitting, instrumentation, and equipment installation. Expect strict safety certifications and specialised trade requirements on site.
C3+ Stream
IndustryA natural gas liquid (NGL) mixture containing propane, butane, and heavier hydrocarbons separated during processing. Subcontractors working at gas plants or fractionation facilities will handle, transport, or maintain equipment tied to this product stream. Understanding its composition helps crews follow correct handling, storage, and safety protocols on site.
Support Activities for Oil and Gas Operations
IndustryAn industry classification covering subcontractors who provide services to upstream oil and gas producers without extracting resources themselves. This includes well servicing, site prep, equipment rental, and pipeline support. Most field service companies in oil and gas fall under this category for tax and regulatory purposes.
Microgrid
IndustryA small, self-contained power system that operates independently from the main utility grid. Subcontractors working remote sites often rely on microgrids for consistent site power. Knowing the local power setup affects equipment compatibility and fuel logistics planning.
Bentonite
IndustryA natural clay mineral used in drilling fluids to stabilise boreholes and suspend drill cuttings. Subcontractors handling bentonite slurry must follow site-specific mixing and disposal procedures. Improper handling can trigger environmental compliance issues and project delays.
