Seismic Imaging: A Review of the Techniques, their Principles, Merits and Limitations

Presenters: Etienne Robein
In co-operation with


EAGE

Date: Saturday 25 to Sunday 26 February 2012
Time: 0830-1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $1,265.00 per person

More Information

As the search for new resources means that we are forced to maximise the production of discovered reservoirs and explore new ones in domains that are increasingly complex, seismic imaging is becoming more and more important as a tool.
Seismic imaging is the ultimate stage of a time-consuming and complex data processing sequence that aims to produce accurate images of the Earth’s subsurface suitable for interpretation by geoscientists.

This course will give the audience an overview of today’s most popular seismic imaging techniques used in the oil and gas industry. Two main classes of techniques are addressed: time-imaging and depth-imaging. Both approaches require an estimate of how fast the seismic waves travel at any given point in the Earth, but with different degrees of accuracy. If time-imaging embeds velocity analysis almost naturally, though at a cost in image quality, depth-imaging requires the explicit construction of a velocity model. Recent advances in seismic acquisition, imaging technology and high performance computing, allow us to correctly take into account a much greater complexity of subsurface model and consequently, start to image structures that were previously invisible.

The course will present in simple terms (no equations!) the principle of different techniques in each class of methods, while pointing out their respective merits and limitations. The relationship between acquisition and imaging on the one hand and interpretation and imaging on the other will also be discussed.

Oil Field Applications of Passive Seismic

Presenter: Peter Duncan
Date: Sunday 26 February 2012
Time: 0830-1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $200.00 per person

More Information

This workshop will focus mainly on the development of microseismic monitoring of hydraulic fracturing for shale reservoir development. Case examples from the various shale basin North America will be included.

In a very real way, passive seismic, especially microseismic monitoring, is to conventional seismic as a stethoscope is to a sonograph. It is continuous 4-D. It is accomplished by listening carefully to the sounds emanating from the earth and then diagnosing what is happening down there. Passive seismic techniques can create not only an image of the reservoir and its plumbing, but also shed light on how the fluid is flowing through the pipes. While interest in passive seismic an E & P tool has grown exponentially over the past decade, the technology is not fundamentally new. Rather it is a re-engineering down to oilfield scales of what researchers have practiced for decades as “solid earth seismology”. The basic elements are seismic event location and travel time tomography.

Grasping the completeness of the passive science, one can see that it provides the opportunity to contribute over the lifetime of an oilfield from discovery to abandonment. Passive seismic can accomplish reconnaissance 3-D exploration at an attractive cost and lead to new discoveries. Microseismic monitoring of a hydrofrac can and does provide valuable information on completion and development strategy. Gas or fluid injection operations for primary or secondary recovery are prime candidates for passive monitoring to prove regulatory compliance, validate reservoir conformance and estimate recovery efficiency.
This one day class will present a brief history of the development of passive seismic techniques, a discussion of state of the art through case histories that illustrate the various applications of the technology and a vision on where this technology will play a role in the smart oil field of the future.

Fundamentals of Coal Seam Gas for Geophysicists – What We Do Now, and What We Will Do in the Future - SOLD OUT

Presenter: Scott Thomson
Date: Sunday 26 February 2012
Time: 0830 - 1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $400.00 per person - SOLD OUT

More Information

The Coal Seam Gas industry is the new emerging energy star in the Australian resource sector.  The supply of LNG to Asian markets has produced an industry worth many billions of dollars to the economy of Queensland in particular.  The role of geophysics in CSG is still evolving, and is by no means as mature, valued or integral to the CSG sector as it is for other commodities.  What geophysical techniques can really make a difference in the identification, evaluation and monitoring of CSG projects?  This workshop aims to educate geophysicists in the fundamentals of Coal Seam Gas, and specifically identify what role, if any, geophysics can play in the development of this burgeoning industry.  The workshop will address the unique geological nature of a CSG play, and will attempt to provide a landing on the kind of geophysical techniques that can potentially make the difference in the success or failure of a CSG program.

A Practical Overview of Seismic Dispersion (SEG DISC 2012)

Presenter: Chris Liner
Date: Sunday 26 February 2012
Time: 0830-1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $310.00 per person (SEG member), $210.00 per person (SEG student member), $400.00 per person (non-member)

More Information

The classical meaning of the word dispersion is frequency-dependent velocity. Here we take a more general definition that includes not just wave speed but also interference, attenuation, anisotropy, reflection characteristics, and other aspects of seismic waves that show frequency dependence. At first impression, the topic seems self-evident: Of course everything is frequency dependent. Much of classical seismology and wave theory is nondispersive: the theory of P- and S-waves, Rayleigh waves in a half-space, geometric spreading, reflection and transmission coefficients, head waves, and so forth. Yet when we look at real data, strong dispersion abounds. This course is a survey of selected frequency-dependent phenomena that routinely are encountered in reflection-seismic data.

Topics include:

1) Time and frequency
2) Vibroseis harmonics
3) Near surface
4) Anisotropy
5) Attenuation
6) Interference
7) Biot reflection

Who should attend

The course is framed along the lines of acquisition, processing, and interpretation to contain material of interest to the entire spectrum of seismic geophysicists. The mathematical level of the course is generally on the advanced undergraduate level, but deeper aspects often are included for advanced readers. Familiarity with the Fourier transform and related topics will be beneficial. In all cases, theoretical developments are illustrated by examples or case histories.

Inversion involves the extraction of an estimate of the subsurface geology from a set of geophysical measurements.  This course will focus on the inversion of seismic amplitude data to extract the velocities and density of the reservoir, from which we can infer reservoir properties such as porosity and fluid content.

The course will stress the physical principles behind inversion and AVO, and illustrate these methods with real data examples from throughout the world.

Course Outline

Part 1   Introduction
Part 2  Rock physics and fluid replacement modelling.
Part 3   Post-stack seismic inversion.
Part 4   AVO and pre-stack seismic inversion.

Date: Thursday 1 to Saturday 3 March 2012
Time: 0830-1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $1,350.00 per person - SOLD OUT

More Information

An understanding of the principles of sequence stratigraphy is essential for successful prediction and analysis of seismic facies in the subsurface. This short course will provide some knowledge and skills for participants to use in exploration and prospect identification.

This seismic and sequence stratigraphy school includes several class exercises and case history examples integrated with sequence stratigraphic concepts.

Overview
The course will be looking at well and seismic facies, both clastics and carbonates, within a simple sequence stratigraphic framework.
This will operate more as a workshop as there are multiple operational exercises which will have lectures interspersed throughout.
The aim of this is to supply participants with an international spread of real-world examples which can serve as a starter analogue database for future work.
The lectures will show pitfalls and things that went wrong as well as where seismic facies mapping worked.
Participants will construct seismic facies maps in the course.

Inversion of EM data for Mineral Applications

Workshop numbers have been expanded to allow for extra registrations – please register soon to avoid missing out.

Presenter: Doug Oldenburg and Eldad Haber
Date: Friday 24 to Saturday 25 February 2012
Time: 0830 - 1700
Venue: Sofitel Central Hotel, Brisbane
Cost: $600.00 per person

More Information

This workshop navigates the user through 1D, 2D and 3D inversions of electromagnetic data. 1D -2D inversions, and other reduced models, are useful for carrying out checks on data quality, determining background conductivity, and locating anomalous regions. In general however, our geology is 3D and we need to invert the data accordingly. We show how this is accomplished and invert frequency and time domain data from grounded and inductive sources. Natural source electromagnetic data acquired from ZTEM and MT surveys are also inverted.

The attendee is guided through the basic components of EM inversion and associated workflows and detailed understanding is facilitated by "hands-on" experience using 1D and 2D algorithms. The field examples are drawn primarily from a single deposit, and this facilitates a comparison of the results from different surveys.

The workshop is divided into four portions partitioned according to morning and afternoon of the two days.

Part I: General Introduction to Inversion with emphasis on airborne EM

  • Basics of EM surveys (ground/air); sources (controlled or natural); data
  • Workflow for inversion
  • Inversion of synthetic and field data sets

Part II: Ground surveys

  • Inductive sources; grounded sources:
  • Basics of DC resistivity surveying: currents, charges; pseudosections etc.
  • Synthetic model; Field survey example
  • Inversion of DC resistivity data: Use DCIP2D as a training platform
  • Induced Polarization: basics of IP, data types and modelling; field data systems and data plots; inversion of IP data; case history.

Part III: Inversion Workflow

  • Forward modelling
  • Inversion of frequency domain data
  • Inversion of CSEM data (grounded sources); synthetic example; field example/case history
  • 3D Inversion of time domain data; synthetic example; field example

Part IV:  Inversion using natural sources and Summary

  • Why natural sources are effective
  • MT data: Basics; synthetic and field examples
  • ZTEM: Basics; synthetic and field examples
  • MT and ZTEM: potential advantages of working with both surveys
  • Course Summary and discussion on future developments for EM

3D integration of geophysical data sets for exploration and targeting

Presenter: Organised by Mira Geoscience
Date: Saturday 25 February 2012
Venue: Treasury Hotel Brisbane

More Information

This course is designed for geophysicists who want to learn how to properly integrate several streams of exploration data into a consistent numerical 3D earth model that can be used to generate high quality drill-hole targets for mineral exploration. As quantitative data integration is based on a 3D earth models, this course will review cutting edge techniques to build, validate and ultimately update these models to be consistent with potential fields geophysical data. Case studies will be explored using GOCAD/SKUA for rapid 3D geological modelling while magnetics and ground gravity data will be modelled using VPmg. These constitute the toolkit we will use for constrained geophysical inversions. A review of petrophysical analysis and classifications to generate lithology from geophysical inversion results will be included. Integrated models are then analysed using exploratory data analysis methods to highlight spatial and quantitative correlations between model components that will ultimately be used as input criteria for 3D Mineral Potential Mapping aimed at defining drillhole targets.
