PESA NSW October 2019 Technical Lunch

Tuesday, 8 October, 2019 @ 12:00 pm - 2:00 pm


Guest Speaker: Dr. Kevin Hill (University of Melbourne)

Kevin is a structural geologist who has over 30 years’ experience in industry and academia. He worked for BP in Canada and London in their structural specialists group and completed a PhD on the PNG fold belt. He has taught at La Trobe and Melbourne Universities and consulted with many companies in Australia and SE Asia. Kevin has worked for the last 10 years with Oil Search Ltd and now teaches courses and consults throughout SE Asia, and carries out research with the Basin Genesis Hub at the University of Melbourne.

Talk Summary:

A team at the Basin Genesis Hub has been analysing the tectonic evolution of Australia’s southern margin in the Bight Basin, using the Ion seismic data, gravity modelling, GA deepwater seismic data and the newly available high quality 3D data across the Ceduna Delta. The goal of the project is to determine the tectonic evolution, particularly in terms of the subsidence history and uplift and erosional pulses recorded on the seismic data in the Ceduna Delta. These events have a significant impact on the hydrocarbon prospectivity.
The Ion and gravity data have been used to define the deep basin geometry down to the Moho and the GA seismic data have been reinterpreted to indicate palaeobathymetry in the now deep-water parts of the basin and the likely facies. A regional section across the delta has been reinterpreted to show deposition and deformation through time with emphasis on the erosional events and water depths. Using this information a regional section across the basin has been fully balanced and restored, using Move, including decompaction and restoration to paleowater depths. This has allowed a model to be developed for the basin evolution which can predict the timing and size of structural traps, the timing of maximum burial and hydrocarbon charge and the direction of charge (landward vs seaward). The next step is full Underworld finite element modelling of the basin to predict temperature through time and hence hydrocarbon charge.
