SUNDAY 18 NOVEMBER 2007     8.30am - 5.00pm
Basins and Crustal Architecture Mapping Using Potential Field Geophysics

The Workshop will present Sedimentary Basin and Crustal Architecture mapping studies using integrated 3D geological and geophysical interpretation, with particular emphasis on the application of gravity and magnetics datasets. The advantages of using gradient and tensor datasets will be highlighted.

An introductory session will explain how intracratonic basins and rifts develop, noting the gravity and magnetic signatures that are likely to be observed. The body of the Workshop will then combine applied interpretation examples and case histories with introductory theory and explanation of geophysical techniques used. There will be some practical demonstrations of selected techniques.

Application examples will include petroleum and minerals examples from sedimentary basins (Dr Peter Gunn), studies from North African oil/gas basin projects (Dr. Alan Reid) and depth to basement mapping and crustal architecture studies applied to basin studies and deep mineral systems (Dr. Peter Milligan, Tony Meixner).

Short practical sessions will demonstrate filtering, Euler deconvolution, the process of creating a depth to basement maps and enhanced visualisation techniques.

This workshop will interest geologists and geophysicists wanting to maximise the value of regional geophysical datasets applied to sedimentary basin exploration projects.

Understanding Seismic Anisotropy in Exploration and Exploitation
Presenter: Leon Thomsen (BP Amoco Upstream Technology, Houston, Texas, USA)
SEG/EAGE Distinguished Instructor
All rock masses are seismically anisotropic, but we generally ignore this in our seismic acquisition, processing, and interpretation. The anisotropy nonetheless does affect our data, in ways that limit the effectiveness with which we can use it, as long as we ignore it. In this short course we will understand why this inconsistency between reality and practice has been so successful in the past and why it will be less successful in the future as we acquire better seismic data (especially including vector seismic data) and correspondingly higher expectations of it. We will further understand understand how we can modify our practice to more fully realize the potential inherent in our data through algorithms which recognize the fact of seismic anisotropy.

THURSDAY 22 NOVEMBER 2007     8.30am - 5.00pm
Petroleum Electromagnetics Workshop

A one day workshop on the theory and application of CSEM and MTEM methods presented by some of the world's leading researchers in the field.

Marine electromagnetic methods in the hydrocarbon industry
Presenter: Lucy MacGregor, OHM Ltd

Marine electromagnetic methods are becoming an accepted part of the explorer’s toolkit.  Marine controlled source electromagnetic sounding uses a high powered source to transmit a low frequency signal through the earth to an array of seafloor receivers.  The received signals are analysed using a combination of forward modelling, inversion and imaging techniques to provide sections and volumes of resistivity within the earth, to depths of several kilometres. 

This presentation will begin with an introduction to the method and how it can be applied in exploration and appraisal. The factors underlying the sensitivity of the method to hydrocarbon bearing structure and the factors that must be considered when designing and optimising a survey will be discussed.  The practicalities of data acquisition will be illustrated using examples from surveys in a range of environments.    Data interpretation methods, including inversion and imaging methods, will be illustrated using case studies, and potential pitfalls in these methods highlighted.

An overview of MTEM technology for onshore and offshore environments
Presenters: Dr. Bruce Hobbs & Mr Chris Anderson- MTEM Limited

The Multi-Transient Electromagnetic (MTEM) method is described for both onshore and offshore environments in terms of the underlying theory, the form of earth impulse responses and their modification in the presence of hydrocarbon reservoirs.  1D, 2D and 3D modelling capabilities make a vital contribution to the assessment of targets and several examples of feasibility studies are shown. 

Practical data acquisition methods, keeping real time quality control, are shown to lead to extensive subsurface coverage with many analogies to seismic surveying.  Several ways of examining the collected data are described ranging from simple plots and transformations through to full waveform multi-offset inversions, the latter including unconstrained inversions and inversions constrained by well log and/or seismic information.   Some are available in the field soon after data acquisition and others require more sophisticated inversion at head office. 

The methods described are illustrated with data collected from locations with widely varying surface conditions including surveys undertaken in Canada, India, Trinidad and the North Sea.

SCANNING FOR PROSPECT DETECTION
 Presenters: Friedrich Roth & Svein Ellingsrud, emgs
Scanning is a new application of seabed logging (SBL) for finding prospects in frontier areas and revealing missed reserves in mature basins, thus extending the use of SBL as a proven prospect ranking tool to include prospect detection.

In this presentation, we will start by giving a brief introduction to the SBL method and show how its fundamental principles apply to sparse grid acquisition common to Scanning surveys. This is followed by detailed discussions on survey design, data acquisition and data processing specific to Scanning. We describe how 3D modelling can be used effectively to find suitable acquisition parameters for surveys covering areas in the order of thousands of square kilometres. Scalable data acquisition strategies will be reviewed that provide wide-azimuth data coverage while remaining cost-effective.

Data processing ranges from the creation of "fast-track" anomaly maps while the data are being acquired to azimuth decomposition and advanced reference modelling. The latter accounts for bathymetry and regional background resistivity variations in the survey area. Data examples will be shown that illustrate the various processing methods, while highlighting the geological and business value of Scanning.

THURSDAY 22 NOVEMBER 2007 / FRIDAY 23 NOVEMBER 2007     8.30am - 4.00pm
Core workshop - Giant gas fields of the North West Shelf, Australia
Government of WA, Perth Core library, 37 Harris St, Carlisle

Presenters: Robert Seggie (Woodside), Dr Simon Lang (Woodside), Dr Chris Cubitt (Woodside) and Dr Bruce Ainsworth (Australian School of Petroleum).  Experts on hand will include specialists in ichnology, sedimentology, petrology, and reservoir modelling.

This two-day course will focus on cores from Triassic and Jurassic reservoirs, from fluvial, coastal-deltaic and shelf depositional systems (Mungaroo, Brigadier & Legendre Formations). Experts will guide four groups of up to 10 participants through suites of cores in half-day intervals. Three of the four main core suites come from fields of the Rankin Trend, North West Shelf Australia, a Late Triassic to Middle Jurassic fluvial to marine progression. The fourth suite is also Middle Jurassic marine but from the Sunrise-Troubadour field approximately 1,500 kilometres to the northeast to give a continental scale comparison. Highlights are fluvial facies including palaeosols, coastal and shallow marine to offshore facies. Ichnological, biostratigraphic, and gas productivity controls will be covered. This workshop is a rare, excellent opportunity for E&P geoscientists, petrophysicists and engineers to view and discuss stratigraphic controls on hydrocarbon productivity.

ENVIRONMENT: 

THURSDAY 22 NOVEMBER 2007     8.30am - 5.00pm
Shallow Reflection Seismic Profiling

Presenter: Professor Don Steeples (Kansas University) SEG Distinguished Lecturer

In trying to produce a seismic profile of the near-surface, detecting shallow reflectors is expensive because of the requirement to plant geophones at intervals of 10 cm or less. The effective resolution potential of classical seismic exploration data recorded on land is often determined by geologic conditions in the upper few tens of metres; in addition, the majority of statics problems commonly occur in the upper 30 metres. We have been experimenting with methods of making near-surface 3-D seismic more cost effective. This course will discuss all of the past experiments, both successful and stupid, and point the way forward.
