Workshop Description

This two day workshop comprises a background on remote sensing and mineral spectroscopy relevant for geological and regolith investigations. Lecture-style presentations will be accompanied by hands-on practical sessions processing and interpreting field spectral signatures, remote sensing imagery, integrating their products with available airborne geophysics, DEMs, and GIS information. Remote sensing techniques covered include those utilising the visible to shortwave, thermal infrared and radar wavelength regions. Such techniques can be useful in arid to semi-arid areas where outcrops and regolith can be related to the subsurface geology, supplementing often poorer spatial resolution geological and regolith published information. Also derived compositional information can potentially reduce the requirements of detailed field sampling and focus survey areas for more costly airborne and ground geophysical techniques. The geological interpretation of satellite based Synthetic Aperture Radar (SAR) and high resolution topographic mapping will be demonstrated for areas with significant vegetation cover. Also the application of night-time thermal imagery will be discussed in areas of limited outcrop and where subsurface variations occur in porosity, thermal conductivity and ground water flow. Lectures will also cover caveat issues such as spectral and spatial sensor resolution, atmospheric interference, illumination conditions, surface scattering, vegetation fractional cover and regolith / soil cover. Presented geological case studies investigations will focus on mineral exploration mapping and compare Landsat, ASTER, the recently released WorldView-3 multi-spectral imagery, airborne hyperspectral HyMap imagery and field spectrometer acquired data sets. The benefits of integrating remote sensing products, airborne geophysics, topographic modelled products and GIS information will be described and presented as case study and practical examples. A detailed examination of current (and future) airborne / satellite sensors and field spectrometers will be also described..

Four practical exercises will be included comprising 1) a demonstration of a portable visible-shortwave infrared spectrometer for mineral identification; 2) the interpretation of typical mineral spectral signatures acquired; 3) mineral and compositional map generation techniques using provided software with multi-spectral (ASTER & WorldView-3) and hyperspectral (HyMap) imagery; and 4) integration of remote sensing derived compositional products with airborne geophysics (e.g. aeromagnetics, radiometrics), DEM topographical products and published GIS information.

Workshop Description

Passive seismic surveying using portable instruments that record seismic vibrations in 3 axial components, in the frequency range of 0.1 hertz (or less) to several kilohertz, and over recording times of 1 to 100 minutes, are becoming more widely used in the minerals exploration and engineering industries to cost effectively estimate the thickness and shear wave velocity of loosely consolidated transported regolith or highly weathered bedrock regolith layers sitting above fresh bedrock to a maximum depth of around 500m. By analysing surface wave (‘ground roll’) data in the frequency domain, it is possible to estimate the thickness of low shear wave velocity material above higher velocity substrate where there is a significant contrast in seismic impedance. The various passive seismic surveying methods involve measuring surface wave propagation with an array of sensors, or resonance frequencies of Raleigh waves using a single sensor. The ambient seismic energy is derived from natural and manmade sources coming from all directions. Survey results are most reliable when velocity vs depth models and frequency vs depth data are locally calibrated to geological layers and bedrock depths from boreholes. There are a number of seismometer types and survey configuration styles available for acquiring passive seismic data, and these will be presented, along with the theory behind the passive seismic method, data recording and processing, and noise analysis conventions. Most emphasis will be placed on the H/V peak frequency method for rapid surveying, with some review of SPAC and FK methods. Then there will be presentations on calibration and modelling, inversion, anisotropic ground conditions, seismic sources, pitfalls, and a number of Australian and overseas case studies will be presented covering mineral exploration applications, environmental studies, engineering applications and others. Key presentations from this workshop/symposium will be selected for journal publication in a special edition of ASEG’s Exploration Geophysics to be dedicated to near surface passive seismic studies.

Brief Outline

Presentations by experts in the field giving an introduction on passive seismic theory, survey methods, data handling and processing, noise issues and standards, followed by modelling and subsurface mapping, then case studies across multiple disciplines and applications, followed by avenues for further research and development.

Workshop Description

Cooperative and joint inversion of seismic and MT data has potential to recovery rock properties across a wide range of rock types from surface to great depth. It is likely to gain in significance within the hydrocarbon, geothermal, groundwater and minerals industries as well as for crustal scale research. A multitude of workflows are starting to appear, ranging from strict joint inversion based on structural or petrophysical constraints, to more manual, adaptive methods dependent on recognising underlying site specific relationships. Within a collaborative workshop setting we examine a range strategies and support the discussion with industrial scale cooperative inversion case studies using co-located 3D seismic and MT data, from several geological settings. We will also provide examples of how geo-statistics can be used within cooperative inversion and finally examine the role of supercomputing resourced such as the Cray Cascade system located at the Pawsey Supercomputing Center in Perth, WA.

Brief Overview

1. What is common in Seismic and Electromagnetic Parameters (A/Prof Brett Harris)
2. Field acquisition and how it impacts on the final result (Prof. Anton Kepic,)
3. Data preparation required before cooperative inversion can be attempted (seismic processing, depth conversion, MT data processing)
4. Supercomputing and visualization in cooperative inversion (Dr Andrew Pethick)
5. Strategies for Cooperative and Joint inversion (using structural and/or petro-physical relationships)

Workshop Description

The Airborne Gravity 2016 workshop is the third in a series of workshops that have been organized at ASEG conferences at time intervals of 6 years - i.e., following on from Airborne Gravity 2004 and 2010. The 2016 version will provide an overview a nd timely update of the very latest developments in airborne gravity (AG) and gravity gradiometry (AGG), equipment, acquisition, processing and interpretation for minerals, energy, near-surface and geodesy application.

Brief Outline

The Airborne Gravity 2016 workshop program has been organized around four themes:

1. Developments in airborne gravity (AG) and airborne gravity gradiometer (AGG) systems
2. Processing of AG and AGG data
3. Interpretation of AG and AGG data
4. Integration of AG and AGG data with other data sets

The workshop organizing committee has invited the world leaders in each of these topics to provide a wide and knowledgable perspective on the current state-of-the-art. Attendees will gain awareness of the technologies and a confidence that they can make appropriate decisions as to when and how to apply these technologies for their own projects.

Workshop Description

3C seismic applications provide enhanced rock property characterization of the reservoir that can complement P-wave methods. The continued interest in converted P- to S-waves (PS-waves) and vertical seismic profiles (VSPs) has resulted in the steady development of advanced vector wavefield techniques. Shear waves are coupled with P-waves, and although they do not respond to fluid properties of the medium they are nevertheless very sensitive to anisotropy and provide direct estimates of shear moduli (rigidities). When the full elastic response is recorded in a VSP survey, vertical components of the wavefield are obtained to calibrate surface 3C seismic data in depth. PS-wave images along with VSP data can be used to help P-wave interpretation of structure in gas obscured zones, of S-wave impedance and density characterization in unconventional reservoirs for lithology and elastic property discrimination, and of fracture characterization and stress monitoring from S-wave birefringence analysis. The course will give an overview of 3C seismic theory and practical application: from fundamentals of PS-waves and VSPs, through to acquisition and processing including interpretation techniques. The emphasis will be on unique aspects of vector wavefields, anisotropy, and the important relationships that unify S-waves and P-waves. Various applications and case studies will demonstrate image benefits from PS-waves, elastic properties from joint inversion of amplitude variations with offset/angle (AVO/A), and VSP seismic methods for improved reservoir characterization.

Course Overview

Gravity and magnetic data are among the oldest geophysical data acquired for the purpose of resource exploration and exploitation. They currently also have the widest areal coverage on the Earth, span a great range of scales, and play important roles in mineral, energy, and groundwater arenas. The interpretation methods have evolved from data map-based visual inspection, various map enhancements, and depth estimation, to quantitative interpretations based on inversions and integrated modeling. In particular, 3D inversion techniques have emerged as a major component in this evolution. The availability of 3D inversion techniques has advanced potential-field interpretation from 'anomaly bump hunting' to 3D imaging of the subsurface by reconstructing the distribution of density or magnetic properties in various geological units and, thereby, have shifted interpretations from the data domain to the model domain. Similarly, inversion techniques are also poised to make major contributions to integrated modeling and interpretation, as well as to differentiating and characterizing geology, geological processes, and reservoir dynamics. This course will focus on the methodology, numerical computation, solution strategy, and applications of 3D physical property inversions of gravity and magnetic data sets. The course is designed to have two tracks in order to meet the different needs of EAGE community in mineral exploration and in oil & gas exploration and production. We achieve this by dividing the course into two parts, and cover the methodologies common in potential-field methods in Part-I and discuss tools and applications specific to mineral exploration or oil & gas reservoir monitoring in Part-II.

1. Framework for effective engagement: an understanding of the purpose behind planning, delivering and evaluating effective community engagement
2. Structures: a consideration of possible structures that support effective community engagement featuring Community Consultative Committees
3. Tools: a demonstration of various tools that can be used to manage information, secure and document progress and measure success.

Workshop Description

In the mineral exploration industry, diamond core drilling provides the opportunity to collect structural data relating to a target or deposit. This enables improved and early knowledge and understanding of geological and mineralisation controls of a target, with an outlook to creating all-inclusive informative models from combined surface mapping, geophysics and downhole lithology and geochemical assay data. Quality structural data are invaluable to any project, from greenfield exploration to ore body definition in an advanced project with established reserves. Understanding the structural context of a project enables further exploration, ore envelope and shoot definition, and geological control on parameters for grade interpolation.This short course summarises the technologies available in exploration and mining and describes techniques of core orientation, marking-up, structure measurement and the visual representation of structural data. We provide a critical comparison of tools and methods available at each stage of the process.

The course is based on the published research paper: Bright, S., Conner, G., Turner, A. and Vearncombe, J.R. 2014. Drill Core, Structure and Digital Technologies. Applied Earth Sciences (Transactions Institute Mining, Minerals and Metallurgy B), 123: 47-68.
