The day-long course is aimed at:

• Seismic interpreters who want to extract more information from their data.

Title: Three-dimensional seismic imaging of shallow crustal volcanic plumbing systems

Presenter: Simon Holford
When: Wednesday, June 13th, 2018
Time: Drinks and food from 5:30 pm, presentation from 6:15 pm

Cost: Members: free, Non-members $10, Students: free
Where: Coopers Alehouse, 316 Pulteney St, Adelaide.

Abstract:

Developing a clear understanding of the movement of magma through Earth’s crust, where it is temporarily stored, to the surface where it erupts, is a grand challenge in the Earth Sciences. Detailed knowledge of the geometry and connectivity of the conduits and reservoirs (e.g. subsurface sheet intrusions such as sills, laccoliths and dykes) that form sub-volcanic plumbing systems (VPSs) is critical to understanding a range of fundamental, interdisciplinary research problems including continental breakup and the thermomechanical state of the mantle, the physiochemical evolution of magma and the forecasting of volcanic eruption dynamics. Addressing these problems is challenging because active VPSs are generally inaccessible. VPSs are traditionally viewed as comprising vertically stacked magma reservoirs linked by dykes, such that eruption sites of directly overlie the sources of melt generation in the upper mantle or lower crust. This presentation will show how the application of three-dimensional (3D) seismic reflection technology to permit the study of ancient, buried VPSs offshore Scotland and in the Great Australian Bight in unprecedented scale and detail, has challenged the traditional view of VPSs, suggesting that in certain cases, VPSs can be dominated by extensive, interconnected sill complexes that facilitate lateral upper crustal magma transport over distances of tens of km, in some cases leading to voluminous volcanic eruptions. It will also show how 3D seismic analysis of VPSs can help reduce exploration risk in energy-rich sedimentary basins.

Talk abstract

The marine seismic industry is constantly striving for greater efficiency in acquiring seismic data: the quicker a survey area can be acquired, the more competitive the cost to the customer. But acquiring large surveys with unconventional spreads can impose limitations on the recorded data, so that certain geophysical requirements for the exploration or development objectives may be compromised. This is especially the case in shallow water areas, where traditionally the width of the streamer spread is restricted in order to image the shallow section.

We will look at some modern acquisition approaches for towed streamer seismic currently offered in the industry; these are very different ideas, but each aims to provide increased cross-line density or improved acquisition efficiency, or indeed, both.

In particular, we will look at the use of multiple sources instead of the conventional dual-source configuration, the use of the cross-line component in multi-sensor recording, an approach based on compressive sensing, and an imaging approach that exploits free surface multiples to provide greater illumination of the near surface. For each

of these approaches we look at its value proposition and ask how well it stacks up to its promise, and what are, if any, the associated limitations and concerns regarding the resulting “data quality”?

Speaker biography

Maz Farouki has a BSc degree in physics from Manchester University and more than 40 years of industry experience with seismic contractors, mostly on overseas assignments. He has lived and worked in the United Kingdom, Zaire, Pakistan, Algeria, Egypt, the United States Australia, Norway, Singapore and Malaysia, holding technical and management positions in data processing, imaging, and marine geophysics. Most of his tenure has been with two employers: the Seismograph Service Companies from the late 1970s and Petroleum GeoServices (PGS) from the 1990s. For a number of years he specialized in velocity model building and depth imaging at a time when the discipline was in its infancy in the industry. His current position is geophysical advisor for PGS Asia Pacific Marine Contract based in Kuala Lumpur, Malaysia. He is an active member of SEG and EAGE and has received ‘best paper’ awards at industry regional conferences and workshops.

The SA-NT branch advises that their  next event is the Annual Student Pizza Night, which will be jointly held with the Adelaide University Geological Society. Each year we hold this event at the University of Adelaide with the aim to promote the opportunities and benefits of studying geophysics to undergraduate students. We will have industry professionals giving talks on their careers followed with pizza and drinks with a chance for industry professionals and students to network. We hope as many members as possible can make it to chat with the students and share their own experiences.

This year we will be joined by Josh Sage, Geoscientist at Beach Energy and former geology & geophysics student at the University of Adelaide, and Nick Jervis-Bardy, a graduate geophysicist at Heathgate. This represents a fantastic chance for students to hear about the breadth of opportunities that our industry can offer them and a great opportunity to network with industry and government geophysicists. The ASEG SA/NT Branch is very thankful for Josh and Nick for agreeing to join us.

Title: Annual Student Pizza Night
When: Tuesday 17th April 2017
Time: Food, Drinks and Presentations from 6 pm
Where: Sprigg Room, Upstairs in the western end of the Mawson Laboratories, University of Adelaide, corner of Frome Rd and Victoria Dr.

DATA VISUALISATION & INTEGRATION: AN UNDERGRADUATE PERSPECTIVE ON THE FRANK ARNOTT AWARD

Over the summer of 2016/17, a team of students from the University of Adelaide were brought together to develop a unique proposal for the Frank Arnott Geophysical Challenge (http://www.frankarnottaward.com), with a focus on data integration and visualisation.

Geoscientific data is critical to exploration success, yet as projects move deeper under cover it is more critical than ever to maximise the value of existing data. Our challenge was to develop a means of integrating and manipulating the data to provide a clearer picture to better tell the story of the geological structures of the Gawler Craton. For this we used  Wavelet Transformations to alter 2D geophysical datasets into 3D datasets using the Poisson Wavelet and to work out the Fractal Dimensions. Subsequently we were tasked with  developing an innovative method of visualising that data to give a unique experience and improve interaction and comprehension of the data. This was achieved by interactively projecting data onto a 3D surface to be able to locate areas of interest and see through the subsurface to better understand the geology.

Ultimately the aim of this project is to lend itself to the exploration industry and examine new ways to approach the challenges faced by geoscientists today and tomorrow. We developed a simple method of data integration and visualisation that uses all open source programs and accessible materials.
