Course description

This course covers modern techniques in 3D seismic acquisition, introducing the seismic experiment as an integrated system composed of acquisition design, field operations, data processing, imaging and interpretation. This two-day course emphasizes how practical aspects of interpretation, data processing, imaging and/or field operations can either constrain, or liberate various survey design parameter choices.

The concept of adjusting survey design parameters for optimum imaging of the subsurface target, while honouring equipment and surface constraints, will be reinforced by using in class exercises, with examples of cutting edge seismic acquisition projects from around the world. These case histories will emphasize wide aperture, wide azimuth and multi-azimuth techniques for onshore, offshore and OBC acquisition 3D designs.

 

Course objectives

Each participant will gain a better understanding of the selection process for basic survey design parameters and how those parameter choices affect acquisition operations, data processing and the quality of the final image volume.

 

Course outline

About the instructor

Jack Bouska graduated with a Geophysics degree from the University of Alberta (1980), working at Seiscom-Delta (1981) then Western Geophysical (1983), before joining Dome Petroleum in 1985 and continuing through the Dome-Amoco-BP mergers of 1988 & 1998. He has lived in; London U.K., Muscat Oman, and Calgary Alberta, tackling a wide variety of projects spanning across five continents. He initially started by revitalizing cost effective exploration in Canada using his invention of Sparse-3D, later expanding into the S. American Andes, with some of the world"s largest Heli-portable 3D"s. His innovation continued with novel acquisition techniques for Seabed OBC-3D"s in the North Sea, Caspian Sea, Gulf of Suez, Abu Dhabi, Indonesia and West of Shetlands. While in the UK, Jack also acted as team Leader for the upstream technology Reservoir Management team, prior to moving to Oman as the Middle East region Seismic Delivery Manager, where he instigated several ultra-high speed Vibroseis surveys made possible by his invention of Distance Separated Simultaneous Sweeping (DS3). In 2013 he moved back to Calgary to manage BP"s Oil Sands and Canadian offshore seismic programs, before retiring in 2015.

Jack's innovations in acquisition design and processing have been recognized by numerous geophysical societies; including the CSEG with the Best Theme Paper award in 1995, Best of Session papers in 1997 & 98 and best technical luncheon talk of 2014. The SEG also awarded Jack the Best Paper in the Leading Edge 2005, and Honorable Mention in Best Paper category, 2005 National convention. Jack has served as an EAGE Distinguished Lecturer for 2007-2008 and in 2009, the Society of Exploration Geophysicists selected him as the spring SEG Distinguished Lecturer in Geophysics. The SEG lecture was delivered at more than 40 venues, in 30 cities, across 15 countries, spanning five continents reaching approximately 2500 geophysicists world-wide during 2009. Jack is a member of the EAGE, SEG, CSEG, and APEGA.

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.

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.

Image Log Interpretation

Instructor: Prof. Peter Lloyd (Honorary Professor)

The course has been designed for geoscientists, engineers and other technical staff who want to analyze 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.

Migration, Velocity Model Building and Updating

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.
