  2 days


  Geology – Geological Modelling






  10 CPD points




Course description

The course is designed for geoscientists, engineers and technical staff who wish to analyse and integrate image and dip data with other logs and seismic to enhance their understanding of exploration plays and field development. It leans heavily on worked class examples and case studies. Instead of interpreting image and dip data in isolation, the course shows how they can be used in conjunction with cores, other logs, modern depositional analogues, outcrop studies and hi-resolution seismic data to refine reservoir models. Tool principles, processing and quality control are discussed in the context of a deepwater case study with the IGNS in New Zealand. This is followed by a description of how images and dips can be used to interpret structural features and fault analysis. Day one is concluded with case studies on fractured basement, carbonate and geothermal systems. On day two, image and dip applications in sedimentary systems are introduced with a discussion of Eolian settings and case studies from fluvial and deltaic settings where exploration plays are enhanced and seismic attributes calibrated to map reservoir hydraulic units. It continues with an analysis of the depositional controls on the petrophysics of siliciclastic and carbonate reservoirs in shelf and deepwater settings. The value of using image data to better evaluate thinly bedded reservoirs is also stressed.


Course objectives

Upon completion of the course, participants will be able to understand how to quality control, process, interpret and integrate images and dips with petrophysical and seismic data to characterize reservoirs and improve exploration and field development strategies.

Full Waveform Inversion in an Anisotropic World. Where Are the Parameters Hiding?

Instructor: Prof. Tariq Alkhalifah (KAUST)

The course starts by introducing the fundamentals of full-waveform inversion (FWI) starting from its basic definition. It focuses on the model update issues and provides analysis of its probable success in converging to a plausible model. In the course we will discuss the many challenges we face in applying FWI on seismic data and introduce modern day proposed solutions to these challenges. The focus of the course will be on FWI applied to anisotropic media. As a result, the course will also introduce anisotropy, its optimal parametrization and wavefield simulation in such media. Practical multi-parameter inversion for anisotropic parameters requires an optimal FWI setup. We will discuss such a setup, which includes the proper parametrization of the medium and data access scheme necessary for a potential convergence to a plausible anisotropic model.

Principles and Applications of Seismic Interferometry and Ambient Noise Seismology in Hydrocarbon Exploration

Instructor: Dr Gerard Schuster (KAUST)

This one-day course is designed for a broad range of seismic researchers, data processors, and interpreters working in the petroleum industry. The course teaches the principles of seismic interferometry, ambient noise seismology and their applications to surface seismic, VSP, and OBS data. The ultimate objectives are to enable geophysicists to evaluate the potential of seismic interferometry in uniquely solving their problems.

Seismic Diffraction – Modelling, Imaging and Applications

Instructors: Prof. Evgeny Landa (Tel Aviv University) and Dr Tijmen Jan Moser (Moser Geophysical Services)

Diffractions have been identified as the key seismic manifestation of fractures and other small-scale reservoir heterogeneities. This two-day course will present the current state-of-the-art of diffraction technology and put this in context by a review of its past developments. The course will cover both forward diffraction modeling and diffraction imaging. Case studies of diffraction imaging will be presented covering applications in seismic exploration and other areas of geoscientific interest.

3D Tomography by Active and Passive Seismic Data

Instructor: Prof. Dr Aldo Vesnaver (The Petroleum Institute)

Building a 3D Earth model in depth is needed not only for accurate seismic imaging, but also for linking well data (as logs and cores) and reservoir simulations. Tomography can build a 3D macro-model for P and S velocities that integrates surface and well data, as well as active and passive seismic. This short course will introduce the basic concepts of traveltime inversion keeping all the math at a very basic level.

Applied Depth Imaging

Instructor: Dr Ruben Martinez (Reservoir Geoscience)

This course has two main segments. In the first segment, the participant will understand the basic concepts behind the tools commonly employed in velocity model building and depth migration.
In the second segment, the participant will learn how to use these tools for building velocity models and generate seismic images in depth using practical work flows for a variety of complex geologic scenarios. At the end of the course, an overview of the emerging depth imaging technologies is presented.

Beyond Conventional Seismic Imaging

Instructor: Prof. Evgeny Landa (Tel Aviv University)

While depth imaging play an increasing role in seismic exploration, data analysis and imaging in time domain play an important role. Moreover, for complex models that request the use of prestack depth migration, time imaging usually constitutes a key first step. The proposed course discusses: a) data analysis and imaging based on new procedures such as Multifocusing and Common Reflection Surface; b) diffraction Imaging based on diffracted energy targeting to image small scale subsurface objects; c) imaging without precise knowledge of the subsurface velocity model (path summation); d) pitfalls and challenges of seismic inversion.

Seismic Depth Imaging and Anisotropic Velocity Model Building

Instructor: Mr Etienne Robein (ERT)

The course will present in simple terms (cartoons rather than equations!) the principle of different techniques in each class of methods (Kirchhoff, Beam Migrations, WEM, RTM), while pointing out their respective merits and limitations. Similarities and differences between Time- and Depth-Imaging will be briefly reminded. In parallel, special emphasis is put on methods used to build the necessary anisotropic velocity models. Both Ray-based techniques (linear and non-linear tomography) and wavefield extrapolation-based ones, including Full Waveform Inversion, are addressed.

Migration and Velocity Model Building

Instructor: Mr Piet Gerritsma (Gerritsma Geophysical Training and Consultancy)

The process of migration, whereby a proper image in time or depth of the subsurface is obtained, is directly related with the velocity model that both serves as input for the migration process as well as is the result of such a migration. Therefore migration and velocity model building are intimately related processes and often applied in an iterative mode. This course gives an overwiew with theory and implementation of the representative migration algorithms as well as of the multitude of ways to build and update subsurface velocity models.

The Principles of Quantitative Acoustical Imaging

Instructor: Prof. Dr Dries Gisolf (Delft Inversion)

This course presents a systematic approach to imaging of acoustic reflection data and the extraction of media property information from the image amplitudes, based on wave theory. Although the approach is valid for a wide range of acoustical frequencies and applications, there is a bias towards seismic imaging.
