G3: Overview of Rapid Geological and Geophysical Modelling in Gocad and Skua = FULL / BOOKED OUT

DATE: Saturday, 21 August 2010

TIME: 0830 – 1700 hours

VENUE: Crowne Plaza, Darling Harbour

COST: $600.00

MIN NO: 15 MAX: 20

Presented by Peter Fullagar, Glenn Pears and Tim Chalke of Mira Geoscience Advanced Geophysical Interpretation Centre, Brisbane

This course is for geophysicists and geologists in exploration and mining roles who want to improve their knowledge or skill base for rapid geological modelling and geologically

constrained gravity and magnetic inversions. The course will provide insight into Gocad modelling techniques and a new geological modelling technology called SKUA for rapid 3D model construction from observation data. These technologies allow for quick creation of complex starting models that are readily incorporated into constrained gravity and magnetics inversion.

The course is strongly focused on state-of-the-art technology and know how for integrating 3D geological and geophysical data into a single, consistent earth model. The course will include hands on model building using Gocad and SKUA, and updating models with UBC GIF and VPmg inversion software.

G6: Geomodeller: Building a 3D Geology Model – Reconciled with Gravity / Magentic Tensor Data

DATE: Friday, 27 August 2010

TIME: 0830 – 1700 hours

VENUE: Crowne Plaza, Darling Harbour

COST: $300.00

MIN NO: 10 MAX: 20

Presented by Intrepid Geophysics Pty Ltd, Melbourne

This workshop will introduce the 3D GeoModeller approach to building a 3D geology model. Users will add new geology data, and revise their interpretive ideas, and will learn that geology models can be easily revised and improved. The workshop will then demonstrate the benefits of computing forward model solutions for gravity and magnetics, including their vector and tensor components. This process effectively ‘tests’ the 3D geology model. The user can revise the model to achieve a 3D geology result which remains consistent with  geology observations, and has improved consistency with geophysical datasets. In the afternoon session GeoModeller’s geophysical inversion will be applied. This stochastic exploration process seeks ‘alternative’ geology models which are also consistent with the set of geology and geophysical constraints. It will be demonstrated that this inversion approach – using vector and tensor datasets – achieves further interpretive improvement and refi nement of the 3D geological model.

CANCELLED - E2: 3D Seismic Survey Design -  CANCELLED

DATE: Monday, 16 August 2010 – Friday,

20 August 2010 (5 Days)

TIME: 0830 – 1700 hours

VENUE: Crowne Plaza, Darling Harbour

COST: $2,100.00

MIN NO: 15 MAX: 20

Presented by Gijs J.O. Vermeer, 3DSymSam – Geophysical Advice, The Netherlands

The book “3-D seismic survey design” authored by the instructor and published by the Society of Exploration Geophysicists is used as a basis for this course. The

main geometries used in 3D seismic data acquisition are orthogonal, parallel and areal geometry. The properties of these 3D acquisition geometries are analysed. Each

geometry can be characterised by its basic subset. 3D symmetric sampling requires that the basic subset of each geometry is properly sampled. This approach maximizes

spatial continuity ensuring optimal spatial fi ltering results including minimal migration artefacts. This theory is translated into practical guidelines for 3D seismic survey design. Case histories and modelling are used to illustrate the concepts and the relation between acquisition geometry and processing, in particular noise suppression and imaging.

The main subjects covered by the course are 2D seismic data acquisition, 3D acquisition geometries, relation between acquisition geometry and imaging, guidelines for 3D seismic

survey design, implementation of nominal geometry, marine 3D acquisition, and converted-wave survey design.

E3: An Integrated Coalbed Methane Exploration Model: Defining Coal Seam Methane Sweetspots

DATE: Saturday, 21 August 2010

TIME: 0830 – 1700 hours

VENUE: Crowne Plaza, Darling Harbour

COST: $400.00

MIN NO: 20 MAX: 40

Presented by Andrew Scott, Altuda Energy Corporation, Texas

This coalbed methane short course is valuable to geologists, hydrologists, geophysicists, and petroleum engineers, who want learn the basic fundamentals and/or review latest

technologies that are applicable to coalbed methane exploration and resource development.

This course is designed to review the fundamentals of coal seam methane for those new to the play, and to provide additional details about various aspects of coalbed methane

exploration and development for those who are already familiar with coal seam methane.

The course will provide a “hands-on” overview of coal seam methane including how coal reservoirs and coal seam methane production differs from conventional gas plays. A coalbed methane exploration model emphasising key geologic and hydrologic controls on coal-gas production will be reviewed during the course.

E4: From Refraction Tomography to Refraction Attributes with the GRM & RCS

DATE: Friday, 27 August 2010

TIME: 0830 – 1700 hours

VENUE: Univeristy of NSW COST: $500.00

MIN NO: 12 MAX: 20

Presented by Derecke Palmer, Senior Visiting Fellow in Geophysics, The University of New South Wales

Model and field case studies demonstrate that refraction tomograms are very similar to the starting models. The major effect of refraction tomography is largely cosmetic, because

it does not improve resolution. Accordingly, the selection of the inversion algorithms can be critical. Detailed models of the regolith can be derived from refraction attributes

computed with the GRM and from the RCS. More effective integration of geoscientific and engineering data in geotechnical site characterisation can be achieved with the application of multivariate geostatistics to refraction attributes. Furthermore, refraction attributes can be employed in joint inversion with other sets of geophysical data, such as land and airborne gravity data, and airborne electro-magnetic data. Attendees are required to bring their own laptop computer.

solutions to geomechanical challenges in exploration, drilling and production. A variety of applications and real data examples will be presented, and particular emphasis

will be placed on the rock physics basis underlying the use of geophysical data for solving geomechanical problems.The following topics will be addressed:

• Introduction to the effects of stress in the earth

• Sediment compaction and the state of stress in the earth

• Pore pressure

• Stress sensitivity of sandstones

• Wellbore stability and wave velocities near a borehole

• Reservoir geomechanics and 4D seismic monitoring

• Fractured reservoirs

• The seismic anisotropy of shales

CANCELLED- E6: Carbon Capture and Storage: Issues and Opportunities for the Petroleum Industry - CANCELLED

DATE: Friday, 27 August 2010

TIME: 0830 – 1700 hours

VENUE: Crowne Plaza, Darling Harbour

COST: $350.00

MIN NO: 40 MAX: 80

Presented by CCS experts from the Cooperative Research Centre for Greenhouse Gas Technologies (CO2CRC) and its collaborating partners

Burning fossil fuels for energy is a major source of CO2 emissions to the atmosphere. Most anthropogenic CO2 is emitted by coal fi red power plants, though significant CO2 is

emitted through the production and separation of CO2 – rich gas. The principle carbon management option of interest to the petroleum industry is carbon capture and storage

(CCS). CCS involves the long-term storage of captured CO2 emissions in subsurface geologic formations. CO2 is captured at the source and transported from the source to the geologic storage site (typically via pipeline). The CO2 is injected via conventional wells into the appropriate geologic reservoir. Migration of the geologically trapped CO2 is carefully monitored and the quantity stored is regularly verified.

This workshop briefly covers the basics of the CCS process and then explores in detail the challenges of the current technology of geological storage, including examples from

working projects.
