PESA WA Branch February Luncheon: More than a pinch of salt

Thursday, February 15, 2018 @ 12:00 - 14:00

Event Categories:

Guest Speaker: Julian Mather

Julian Mather is currently consulting to Spectrum Geo as the Asia-Pacific, Senior Geoscience Advisor, in Perth, WA (2016-present). His role is quite broad but primarily focused on working on Spectrum’s extensive Multi-client seismic library looking to create value and help develop new projects in the region.

Julian has gained global industry experience as a geophysicist after graduating from UTAS in 1984 with a BSc. in Geology and BSc. Hons in Geophysics. However he started his career as a professional sailor before realising this had limit growth potential and headed off to Southern Africa. He work as a Field Geophysicist for JCI doing a broad range of data acquisition from walking around the African savannah collecting mag – gravity data and acquiring seismic to flying in planes at night for infra-red surveys. In 1990 he “went bush” and drove to London picking up a junior interpreter role with Elf Aquitaine in 1991. From here the great journey in a major oil company began, starting in London and then moving to Aberdeen working the North Sea. Five years later he found himself in Paris as part of their international new ventures team where he worked many of the major petroleum basins of the world. Following the merger with TOTAL he was sent to Houston as a Senior Geophysicist working permits and new ventures in the GOM (2001-2005). Angola was the next stop to head up the Non Operated Exploration and Appraisal Team until 2009. Over 20 years later he finally landed back in Australia to be part of the newly opened Total E&P office in Perth where he spent the majority of his time as Head of Geophysics and the Offshore NWS New Ventures team until it was relocated to Singapore. At a cross roads the family decided to step of the expat treadmill, like many before and soak up the Perth life style for a bit longer.

More than a pinch of salt

How broadband reprocessing has highlighted Palaeozoic salt influence in the region of the Browse-Bonaparte Basin boundary reviving the idea of a greater salt province underlying this part of the North West Shelf.

Julian Mather

Although, like the Petrel Sub-basin, there is evidence that Palaeozoic salt was once deposited in the region, the Paqualin-1 well having tagged a salt diapir back in 1988 and a subsequently published a paper in WABS 1984 (E. P. Woods) discussing the possibility, there has been very little further discussion on salt and its potential influence in the region since. Recent broadband reprocessing has now given us the image quality that can unequivocally show that the Paqualin diapir and the Swan Graben are not an isolated occurrence and there are numerous other diapirs and evidence of wide spread Palaeozoic salt influence in the region. This talk will firstly show how improvements in broadband 3D seismic imaging have changed our perception and given us the confidence to extend the model further afield. Examples will then be presented before briefly touching on the implications of halokinesis (not the Pseudoscience version of telekinesis, “the ability to move salt with your mind”) to help unravel the tectono-stratigraphic history of the area and overlooked petroleum potential.
