The Renaissance Tour: A revival of frontier basins with data-driven exploration.

By Lauren Found, Searcher.

Lauren Found of Searcher Seismic took us on a global magical mystery tour from the offshore Papuan Basin to the Scotia Basin offshore Canada on the northern Atlantic margin and the Orange Basin, offshore Namibia with its conjugate the Pelotas Basin offshore Brazil and showed us new insights from new data and interpretation in these basins that make them look more interesting than previously thought.

Lauren showed a new crustal model for the Gulf of Papua interpreted from long offset 2D seismic data suggesting the presence of new and previously overlooked depocenters and the possibility of the contin­uation of the oil provinces that are prolific in the onshore.

On 18th July, PESA-WA held their “Winter Warmer” networking event at The Globe Lounge Bar in Perth CBD, which this year featured a Jazz Quartet. Sophie Kerr and her band (WAPPA and ex-WAPPA students) played fantastic mellow as well as lively jazz tunes. The event was really well attended (62 people). It was a great opportunity to socialise with colleagues, friends and new members, particularly on a cold Winter’s evening. There was an open bar until 10pm, with fantastic food platters and raffle prizes.

Summary by Dr Fiona Burns

On  Tuesday 10th June, DEMIRES (in collaboration with PESA WA and  CCUSNA) organised a core workshop entitled  “Perth Basin from a CCS Perspective” which was  presented by Julie Cass and Dr Arthur Mory. We spent a day at the Perth Core Library considering how our collection of cores helps us to understand CCS targets in the Perth Basin. We also delved into the importance of characterising seals, the influence of reservoir heterogeneity vs homogeneity and how diagenesis impacts pore geometry.

What you should know about borehole images but were afraid to ask…..Forty years of hard-won lessons’ By Lawrence Bourke

Lawrence Bourke of Task Fronterra Geoscience, one of the founders of image log interpretation, took us on a trip down memory lane, back to the embryonic beginnings of image logs with the with the original 8 button high resolution dipmeter of 40 years ago through the revolution (for geologists) of the high-resolution FMS and FMI micro-resistivity devices in the late 1980s and early 1990s at the PESA WA April technical luncheon.
