D066 An Objective Approach to Seismic Processing
D066 An Objective Approach to Seismic Processing
This course covers fundamental issues and linkages involved in acquiring and processing seismic data. The course focuses on the questions that seismic interpreters need to address to determine whether, and how, to re-acquire or re-process existing seismic data. Throughout the class, participants will use case histories and interactive processing tools to improve their understanding of the latest techniques and how to apply them effectively and efficiently to meet their objectives.
This is a virtual classroom course divided into 6 three hour webinar sessions (equivalent to a 3-day classroom course), comprising lectures, discussion and interactive exercises using case histories to illustrate the basic theory and impact of the techniques discussed.
The purpose of this course is to teach fundamentals rather than a particular software suite. To this end, participants will use a series of web-based software modules to experience the processing options available and learn how to combine the basic tools together to build a flow which meets objectives.
Participants will learn how to:
A set of geophysical tools and rules are provided to help assess the quality and value of seismic data in a given area. We then use the methodology to assess the benefits (and costs) of re-processing and re-acquisition using the latest technologies. Seismic modelling provides a central theme to the methodology.
The second main aim of the course is to provide a demonstration of current geophysical and processing techniques that can be applied to seismic data. From a basic knowledge of seismic processing, participants will be given an overview of standard practice, and then for each method we will introduce the basic theory (with few equations), parameterisation, benefits, limitations, pitfalls and likely value. Where possible we will focus on the applications of the techniques using real case histories and common terminology. The whole processing sequence is covered, including data preparation for land and marine data, noise and multiple suppression, velocity model building, statics, time and depth imaging including anisotropy and issues affecting resolution. Interactive processing exercises, using land and marine synthetic and real data examples are provided throughout the course to enable the attendees to grasp the importance of key parameters. We will also cover the generation of specialised outputs used in quantitative interpretation including AVO and inversion volumes and address the challenges and benefits from the current drive to automation within seismic workflows.
Session 1: Workstation Based Workflow: Objective Setting

The following sections are included within the manual but not extensively covered during the online sessions.
This course is aimed towards geoscientists seeking an overview of new geophysical techniques and processing methods and those who wish to more effectively liaise with specialists to improve their decision making and deliver objectives. A geophysics refresher is provided, but participants should have a basic knowledge of seismic acquisition and processing terminology.
Course N080 (Geophysics for Sub-Surface Professionals) or N085 (Introduction to Seismic Interpretation) provide a suitable introduction for those unfamiliar with the basic concepts.
Rob established Tonnta-Energy Limited in 2008 - a Dublin based company concentrating on seismic processing, seismic modelling, seismic survey design and specialized seismic processing including research, training and independent peer review. Basic and advanced seismic processing courses using specially developed web-based processing technology for data analysis have been given to over 800 industry based geoscientists worldwide.
Between 2015 and 2018 Rob worked for PETRONAS in a value assurance role overseeing all aspects of research geophysics from exploration through to monitoring, including technical adviser for high-performance computing within PETRONAS and member of most senior exploration technical team approving international and domestic well locations, acreage acquisitions and relinquishments.
Rob has extensive experience of seismic acquisition and processing from North Sea (UK, Norway, Denmark), West of Shetland & Faroes, Ireland, Poland, Algeria, West Africa, Central Africa, Mexico, South Atlantic, Brasil, Suriname, Malaysia, Thailand, Australia, Indonesia and Vietnam.
Rob has a background in both industry and academia. He worked with Amerada Hess between 1990 to 2001, where he helped establish and eventually ran the geophysical operations group in London working with the research centre in Houston. In 2003, Rob formed and co-led a research program on seismic reflection processing and interpretation funded by the oil industry within the Geology Department at Trinity College, Dublin. This program investigated the Irish continental shelf, publishing more than 20 articles with 7 Ph.D. students and Hardy is still involved in current collaborations and research in Ireland.
His research interests include reflection seismic acquisition, signal and image processing and modelling including determination and visualization of uncertainty due to seismic processing technologies. Hardy has publications on multiple suppression, velocity model sensitivity, imaging beneath complex topography and imaging and positioning of faults on seismic data.
