G'day, and welcome to the Australia special section. We hope you enjoy reading this special section as much as we have enjoyed editing it. The themes are oil and gas exploration and production in Australia and related technical advances. By design, some of the articles we have included here are strong on the exploration side of SEG, and other articles maintain SEG's traditional focus on geophysical technology. The exploration-focused articles will be of most interest to those exploring in or considering exploration in Australia. The articles that feature technology are linked to Australia but obviously have applications outside Australia too.
