This paper sets out to provide a suggested standardised set of nomenclature for seismic interpretation data of different frequency (Hz) spectra in use in the offshore energy sector. Historically, a large number of acronyms have been used to describe seismic interpretation data of different frequency content across the oil and gas industry and now in the rapidly growing offshore wind and carbon storage sectors, but the terms in use have not always been consistent or logical.
This paper sets out to understand the history and background behind the evolution of these terms and to remove the confusion from current usage of MR, HR, UHR, UUHR, VHR, or SUHR by definition of a standardised nomenclature for seismic interpretation data ranging from 4Hz up to 5000Hz in frequency content. It is believed application of such a standard throughout the global offshore energy industry will ensure consistency and a common understanding going forward.
