This guidance was withdrawn on

The Oil & Gas Authority launched a new website on 3 October 2016 to reflect its new status as a government company.

This formalises the transfer of the Secretary of State’s regulatory powers in respect of oil and gas to the OGA, and grants it new powers. This website will no longer be updated. Visitors should refer to www.ogauthority.co.uk

The OGA’s Petroleum Measurement & Allocation Team is responsible for ensuring that UK licensees continue to follow ‘good oilfield practice’ in the measurement of all petroleum won and saved from licensed areas in the UK and on the UK Continental Shelf (UKCS).
