Andrew S. Long is an Australian geophysicist. He has a PhD in geophysics 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, the Australian Society of Exploration Geophysicists, 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, ASEG Best Paper, and Indonesian Petroleum Association Best Paper Professional for Geophysics and Formation Evaluation. 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 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.
