Dr. Andrew S. Long, B.Sc., PGrad.Dip.App.Physics, Ph.D. (1965 - ) is an Australian geophysicist who has gained some notoriety for his presentation skills. Despite a serious spinal accident in 1987, he obtained a Ph.D. in geophysics in 1996 from the University of Western Australia, and has continued his career in both the USA and Australia. He was a leading figure in the development of High-Density 3D (HD3D) technology for seismic exploration, and in the industry promotion of dual-sensor streamer seismic technology. Both 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 categorized as HD3D surveys. Dual-sensor streamers are a next generation technology introduced at the annual convention of the European Association of Geophyscientists 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 on the North West Shelf of Australia. Following several years of publications and presentations at international oil and gas conventions, in 2009 he was honored as the Honorary Lecturer for Pacific South for the Society of Exploration Geophysicists, the largest internal professional society for the geophysical community.
