SEG | DGS Workshop: Challenges & New Advances in Velocity Model Building

9-11 March 2021 I Al Khobar, Saudi Arabia

 

Due to the ongoing global health concerns of the COVID-19 virus, the ‘SEG | DGS Workshop: Challenges & New Advances in Velocity Model Building’ is rescheduled to 9 –11 March 2021. We appreciate your continued support and understanding. Please do not hesitate to email Anneke de Klerk for any further questions.

Velocity model building is the most important and critical element in seismic data imaging. The demands of exploring more complex new frontiers in particular will not be fulfilled without accurate velocity models. Understanding the fundamentals, and then challenging the approximations of seismic velocity estimations, limitations and pitfalls in practical applications, are the main keys of building the most accurate integrated velocity model. This approach, which exploits the relationship between the refraction, reflection, surface waves and non-seismic data, considers the wave propagation which is based on strong simplified assumptions. Accurate velocities are the main challenge for improving seismic data and depth prediction. For example, near-surface irregularities require accurate velocity models for proper imaging of the deep subsurface. Moreover, high-resolution velocities are also desirable for wave-equation based migration algorithms required for subsalt imaging.

 

The workshop is designed to provide insights for geoscientists to better understand the principles and limitations of both current and emerging technologies involved in velocity model building. As a result, participants should ideally understand how contemporary velocity estimation methods work, and what approximations are involved in obtaining computationally tractable solutions.

Workshop Format

 

The format of the workshop will feature presentations by invited key experts who will share their experiences. The workshop will provide a unique opportunity for open and extended discussions among the participants.

 

Six sessions (3 days). We will aim for one keynote speaker per session with a closing session at the end of the workshop to serve as the outlook going forward. The oral presentations are comprised of 20-minute talks followed by 5 minutes of Q&A. After each session, a 30-minute discussion session is planned. The objective of this session is to allow participants to discuss in detail and learn from each other what has worked for them and debate the issues and challenges facing them during their daily workflows. Session chairs will also serve as discussion leaders during the 30 minutes.

 

Poster Presentations are welcome to give ample time to the delegates to discuss the poster topic with the author(s). Posters will be in displayed in the workshop room available for viewing during coffee breaks and afternoon free time following each session.

 

This workshop will aim to address the following topics:
