About Us


Ian Longley is a regional petroleum geologist with 30 years of experience, who has worked for Lasmo, Woodside, Shell and Oil Search in various locations around the planet in junior and executive exploration roles. He has specialised in the plate tectonic evolution, regional petroleum geology, play and prospect analysis and the hunt for new exploration opportunities in the region. He has published extensively on the regional petroleum geology and, after deciding senior management is not for him, is currently enjoying working on his hobbies (now businesses), looking at real geology and not doing budgets or safety reviews, nor attending endless meaningless meetings.

He is joint developer and majority owner of the Player ArcGIS play analysis software which is now used by 30+ international E&P exploration companies around the world. He lives in Perth, Australia where he has survived one shark attack and two forms of cancer and is now an average surfer, whose increasing girth and added floatation makes for an even slower ocean swimmer, and an even easier meal for the local sharks. His optimistic nature with regards to risk management strategies is self-evident in both his personal and professional activities, where he believes that life is too short to take political correctness and established exploration paradigms too seriously, and that everyone should enjoy a good laugh every now and then. He currently runs the very successful industry training course on the Petroleum Geology of SE Asia (www.pgsea.com).

A member of AAPG, PESA, and ASEG, he was awarded the APPEA Lewis G. Weeks medal in 2010 jointly with Robyn for contributions to the Australian industry. He is married, with three children, and lives in Perth, WA.
