From multi-component imaging to ocean bottom seismic technology - challenges or opportunities?

Xiaogui Miao

2021 Honorary Lecturer, Pacific South

7 April, .

Multi-component imaging technology has experienced up and down cycles in the past decades. Even though people were excited by the capability of PS wave imaging through gas cloud structures 20 years ago, oil companies are still hesitant to put the technology into practice over many years due to complicated imaging technology, long processing cycles, and economic consideration.

Multi-physics analysis: extracting the most from diverse datasets

Lucy MacGregor

2021 1Q2Q SEG Distinguished Lecturer

13 April

Understanding the sub-surface is important for many reasons, including resource management and hazard detection. Geophysicists can deploy a range of tools to probe the earth, measuring properties from velocity and density to resistivity and magnetization. This presentation will provide an overview of multi-physics approaches and applications, illustrated using case studies. .

Seismic technology in northern European waters and the prevalence of multiples

Adriana Citlali Ramírez

2021 Honorary Lecturer, Europe

Good ideas tend to stand the test of time. True for several technologies that are called new or revolutionary. Just take a minute and think about blended sources becoming almost standard in seismic surveys within the past five years, invented in the 1980s for seismic exploration purposes, and based on Colin Cherry’s “cocktail party problem” from 1953. .

Understanding seismic wave attenuation mechanisms in porous and non-porous media: Some new insights

Nimisha Vedanti

2021 Honorary Lecturer, South and East Asia

20 April, 

In this lecture, I will give an overview of the seismic attenuation processes and provide a comprehensive study of attenuation mechanisms in two very different scenarios, citing the case studies carried out in Utsira Formation in Sleipner field, the North Sea, and the Deccan Basalt in India. .

Taking the Power of Exploration Geophysics from the Oil Patch to Help Solve the World’s Grand Challenges

John Bradford

2021 Near Surface Global Lecturer

29 April

Geophysicists have an opportunity to utilize the most powerful computation, signal processing, and imaging tools developed in exploration geophysics and apply them to help solve several of society’s grand challenges.
