We're merging our website with our main site to offer a more streamlined experience. To make the switch smooth, this website undergoing maintenance and will be unavailable on the 28th of January 2025. This means you won't be able to purchase publications. Don't worry, everything will be available on the new site by the end of the day. To avoid any hiccups, we recommend holding off on purchases until then. Thank you for your patience, and see you on the new site soon!
Hydrocarbon management
At various stages during the extraction, transportation, refining, storage and distribution of petroleum and its products, there are requirements to measure its quantity and quality for allocation, custody transfer and fiscal purposes, as well as for stock control and loss prevention. To enable the oil industry and regulators to carry out such measurements in a standardised manner, the EI develops and issues guidance documents that reflect current industry good practice.
