A New Inquiry by the Science & Innovation Committee
Committee Secretary Standing Committee on Science and Innovation House of Representatives Parliament House CANBERRA ACT 2600 Email [email protected] Dear Committee-members, I am pleased to provide the response of the Australian Geoscience Council to the Inquiry by the House of Representatives Standing Committee on Science and Innovation into Australian technological innovation and pathways to commercialisation. The Australian Geoscience Council is the Peak Council of geoscientists in Australia. It represents nine major Australian geoscientific societies and has a membership of over 7000 professionals. We believe that the geosciences are critical for Australia, as shown by the accompanying sample of innovative technology case studies in the geosciences. Our submission is made in four parts: • This cover letter and a one page Executive Summary containing the Geoscience Council’s eight recommendations, • Eleven pages responding to the eight Terms of Reference for the Inquiry and developing the rationale behind the Geoscience Council’s recommendations, • Twenty one appendices (pages 14 to 46), each providing a summary case study of technological innovation in the geosciences, • Appendix 22 (page 47) which describes a relevant activity from another country. The resource industry in Australia is characterised by sustained innovation, and the sector continues to create new wealth for Australia with long lead times. Resources (including gold) achieved more of Australia’s export earnings in 2004 than any other sector, while also delivering employment and other flow-on benefits to the community in both urban and remote regions. However, these achievements derive from successful exploration of decades past. In order to project past performance into the future, Australia needs greater innovation in technologies, concepts and knowledge, as well as sustained levels of qualified people. -

Seismic Reflection Inversion with Basis Pursuit
Seismic sparse-layer reflectivity inversion using basis pursuit decomposition Rui Zhang and John Castagna 4800 Calhoun Rd, Department of Earth and Atmospheric Sciences, University of Houston Houston, TX, 77204 ABSTRACT Basis pursuit inversion of seismic reflection data for reflection coefficients is introduced as an alternative method of incorporating a priori information in a seismic inversion process. The inversion is accomplished by building a dictionary of functions, representing seismic reflection responses, and constituting the seismic trace as a superposition of these responses. Basis pursuit decomposition finds a sparse number of reflection responses that sum to form the seismic trace. When the dictionary of functions is chosen to be a wedge model of reflection coefficient pairs convolved with the seismic wavelet, the resulting reflectivity inversion is a sparse-layer inversion, rather than a sparse-spike inversion. Synthetic tests show that sparse-layer inversion using basis pursuit can better resolve thin beds than a comparable sparse-spike inversion can. Application to field data indicates that sparse-layer inversion results in potentially improved detectability and resolution of some thin layers and reveals apparent stratigraphic features that are not readily seen on conventional seismic sections. INTRODUCTION In conventional seismic deconvolution, the seismogram is convolved with a wavelet inverse filter to yield band limited reflectivity. The output reflectivity is band- limited to the original frequency band of the data so as to avoid blowing up noise at frequencies with little or no signal. It has long been established (e.g., Riel and Berkhout; 1985) that sparse seismic inversion methods can produce output reflectivity solutions that contain frequencies that are not contained in the original signal without necessarily magnifying noise at those frequencies. -

UNIVERSITY OF CALIFORNIA Los Angeles Development of Specialized Nonlinear Inversion Algorithms, Basis Functions, Eikonal Solvers, and Their Integration for Use in Joint Seismic and Gravitational Tomographic Inversion A dissertation submitted in partial satisfaction of the requirements for the degree Doctor of Philosophy in Geophysics and Space Physics by Zagid Abatchev 2019 c Copyright by Zagid Abatchev 2019 ABSTRACT OF THE DISSERTATION Development of Specialized Nonlinear Inversion Algorithms, Basis Functions, Eikonal Solvers, and Their Integration for Use in Joint Seismic and Gravitational Tomographic Inversion by Zagid Abatchev Doctor of Philosophy in Geophysics and Space Physics University of California, Los Angeles, 2019 Professor Paul M. Davis, Chair 1 Abstract Many approaches and packages have been developed for tomographic inversion of seis- mic data and have consistently remained in high demand in both academic and industrial geophysics for subsurface imaging. However, our survey of published implementations has shown them to suffer from shortcomings. They include: low computational efficiency lead- ing to overreliance on gradient-based inversion methods, non-robust forward models, and overparametrization of invertible fields leading to overconfidence in parameter resolvability and susceptibility to local minima. Additionally, many suffer from poor algorithmic docu- mentation, lacking source code availability, and complicated dependencies of many published packages, resulting in difficulty with their reproducibility, testing, and adaptation. Finally, most available packages do not incorporate different measurement sets, such as gravitational anomaly data, to better constrain seismic inversion. To address these issues, we have developed our own implementation and integration of an improved set of algorithms for seismic and gravitational tomography and applied it to ii a seismic data set from the Peruvian Andes obtained in a joint experiment with Caltech between 2008 and 2013.
