This Report presents the safety performance of the aviation industry involved in both upstream and downstream operations reported by participating IOGP Member Companies for 2013-2025. It is published as part of the IOGP data series. The data presented have been collected specifically from IOGP Member Companies and are not intended to represent the worldwide oil industry. The principal purposes of this Report are to record the safety performance of helicopter and aeroplane operations of the participating Member Companies in the years 2013-2025, and to provide data that can be used by IOGP Member Companies and others to benchmark their performance. This Report presents overall (worldwide) and regional results against these indicators, and the rates of exposure by aircraft activity performed and type of aircraft flown.
