b'Data trends Data trendsit seems clear that the established seismology formats are not going away as many users find them to be quick and convenient.The ASEG Technical Standards Committee is keen to resolve this problem, and to paint a fuller picture of industry use we are asking for the petroleum industrys views. The petroleum industry does seem to be taking an interest in passive seismic and one 3D seismic company has told us that they have used overnight passive data to supplement their day time active work. One sticking point maybe that while SEG Y r2 is technically suitable for passive Tim Keepingseismic, it appears that using SEG Y r2 Associate Editor for geophysicalis proving difficult - even for those with datamanagement and analysisexpensive petroleum software.

Please email me at input to the formulationtechnical-stadards@aseg.org.au. of a universal passive seismic data formatIn response to earlier columns, and thanks to the interest of Regis Neroni and Mark Duffet. Regis, Mark and I have decided to produce a best practice guide to collecting minerals petrophysical data in the field. The guide will offer a general overview, and practical how to explanations for on-site geologists. There will be additional one or two pages of operational guides for field assistants to ensure consistent and repeatable sampling. A one sheet limit per technique will allow lamination for protection from the elements and heavy handling. The guide will be publicly available through on the ASEG Technical Standards page on the ASEG website.Passive seismic data continues to steadily roll into government archives. However, a universal format has not yet been established, and questions remain about what information needs to be included. Different users are likely to have different answers.
