Andrew S. Long (born 1965) is an Australian geophysicist. He has a PhD in geophysics (1996) from the University of Western Australia, and a post-doctoral term at Stanford University. He is a leader in the application of geophysical technologies to exploration for oil and gas in marine areas, and has written and presented several papers at the Society of Exploration Geophysicists (SEG), the Australian Society of Exploration Geophysicists (ASEG), and many other international conventions and journals.
Early awards include the 1992 Alumni Medal award for outstanding post-graduate from Curtin University of Technology, ASEG Best Presentation (1994), ASEG Best Paper (2004), and Indonesian Petroleum Association (IPA) Best Paper Professional for Geophysics and Formation Evaluation (2009). Leading figure in the application of satellite altimetry technology to the mapping of the marine gravitational field in the early 1990s, the application of modelling methods to 3D seismic survey planning, the development of High-Density 3D (HD3D) technology for seismic exploration, the introduction of multi-azimuth and wide-azimuth 3D technology into the Asia-Pacific region, and in the introduction of dual-sensor streamer seismic technology to the oil and gas industry. The HD3D and dual-sensor streamer technologies were pioneered during his employment with Petroleum Geo-Services. It is estimated that more than half of all 3D towed streamer surveys acquired worldwide by all seismic service companies can now be categorised as HD3D surveys. Dual-sensor streamers (commercial name is GeoStreamer) are a next generation technology introduced at the annual convention of the European Association of Geoscientists and Engineers in 2007, and represent a new tool for identifying oil and gas accumulations in marine sediments. The first-ever dual-sensor streamer survey was acquired in 2008 on the North West Shelf of Australia. A modification of the GeoStreamer technology presented by Andrew Long won an IPA award in 2009.
Following several years of publications and presentations at international oil and gas conventions, in 2009 he was honoured as the inaugural Honorary Lecturer for Pacific South for the Society of Exploration Geophysicists, the largest internal professional society for the geophysical community.
