During the past 20 years, Aria Abubakar's crucial and groundbreaking contribution to the advancement of the science of geophysical exploration and his tireless service to the scientific community have benefited both the oil and gas industry and SEG. It is my great pleasure to write the Honorary Membership award citation for Aria.

Standing at the forefront of technology innovation, Aria's insightful research spans many important areas of applied geophysics. After receiving his PhD from Delft University of Technology, he rapidly achieved a recognized lead status and established himself as a pioneer in the areas of 2.5D modeling and inversion algorithms for crosswell electromagnetics, controlled source electromagnetics, and magnetotellurics. He and his team received a 2010 Hart Meritorious Award for Engineering Excellence for Schlumberger's DeepLook EM technology. The award recognized his distinguished creative achievements in his electromagnetics research and his invaluable initiative and lasting contributions to the progress of this technology, now a main processing workhorse for subsurface information retrieval.

Aria then dedicated effort to pushing forward the potential of seismic full-waveform inversion (FWI). Thanks to his strong interdisciplinary technical background, he invented various unconventional techniques to improve the accuracy and efficiency of FWI, such as automated regularization and contrast source inversion algorithm. Both inventions are not only regarded as real breakthroughs in geophysical inverse problems but also are cited widely and hailed in the world of medical imaging. After that, Aria and his team brought these technologies to the next level by integrating seismic, electromagnetic, gravity, and dynamic information such as production data and demonstrated its great potential in 4D reservoir monitoring applications. Because of the immense and influential impacts of these works, he served as the 2014 SEG North America Honorary Lecturer, giving the lecture titled Joint inversion of multiphysics data for petrophysical and engineering properties.

Since late 2017, Aria has been pushing the utilization of machine learning and artificial intelligence for geologic and geophysical problems. He and his collaborators have shown successful applications of these technologies, such as seismic fault and salt body detection; seismic stratigraphy interpretation; log quality control, correlation, and interpretation; static model building (via seismic inversion and/or property inversion); etc. Due to his drive on the topic, he has been chairing the Data Analytics Subcommittee in the SEG Research Committee. He was selected as a 2020 SEG-AAPG Distinguished Lecturer, offering a lecture titled Potential and challenges of applying artificial intelligence and machine learning methods for geoscience.

Aria plays a critical role in many SEG activities and continuously contributes to the Society in various aspects and fields. He has been serving as an associate editor for Geophysics in the areas of electrical and electromagnetics and seismic inversion since 2011. In 2019, he proposed and successfully organized a special section in Geophysics on machine learning and data analytics for geoscience applications. Aria is the current chair of the SEG Research Committee. In addition, he has been on the SEAM Board of Directors since 2018 and is the board liaison for the SEAM Artificial Intelligence project. This year, he has been working as the Technical Program chair for the IMAGE 2022 conference in Houston and the 2022 Energy in Data conference (a joint event between SEG, the American Association of Petroleum Geologists, and the Society of Petroleum Engineers) in Austin.

Today, Aria's tremendous scientific achievements and his relentless dedication to SEG are recognized with Honorary Membership. His pioneering accomplishments, dedication to innovative research, and exemplary leadership will continue to have a huge impact on geophysical exploration, digital transformation, and other scientific and technology domains.

2020 SEG 3Q/4Q Distinguished Lecturer

Potential and challenges of applying artificial intelligence and machine-learning methods for geoscience

In recent years we have witnessed great achievements accomplished by artificial intelligence (AI), machine learning (ML), and/or data analytics in various areas such as e-commerce, computer vision, social media, self-driving cars, natural language processing, and healthcare. Driven by the advances in the GPU technology, cloud computing, and the rapidly increasing data volumes within the geoscience applications, the energy industry has recognized and embraced the tremendous potential of AI/ML and data analytics. Early research and development utilizing these algorithms for geoscience applications have shown encouraging and promising results. This lecture will present the potential and challenges of AI/ML and data analytics practice in geoscience, as well as the successes and failures to date.

We will discuss a variety of highly successful geoscience applications that leverage AI/ML and data-analytics algorithms to improve efficiency, accuracy, and to automate geoscience workflows, and to explore a new way of extracting values from geoscience data. In addition, we also will touch upon a variety of general questions which naturally arise due to the emergence of these technologies in geosciences. Some of these questions are: What other challenging problems can be formulated and solved effectively by AI/ML? How do we tailor the AI/ML and data analytics algorithms and paradigms to meet the specific properties of geoscience data? How do we fully exploit the power of AI/ML and data analytics while combining them with physical constraints? When should we and should we not apply AI/ML and data analytics approaches? Lastly but more importantly, how can we translate AI/ML and data analytics-based workflows from proof-of-concept works to scalable commercial products.

2014 SEG Honorary Lecturer, North America

Joint inversion of multiphysics data for petrophysical and engineering properties

A variety of measurements may illuminate the reservoir with varying coverage and resolution such as: electromagnetic (EM); controlled-source EM (CSEM); magnetotelluric (MT), surface-to-borehole EM (STB-EM); crosswell EM; seismic (surface seismic, crosswell seismic, and VSP); gravity (surface and borehole); and production history/well testing data. The interpretation of each measurement on its own will provide incomplete information due to nonuniqueness and limited spatial resolution. However, when integrated and combined with other measurements such as near-wellbore data, they may provide considerable value such as, for example, to enable estimation of reservoir properties, to obtain an improved reservoir model, and to provide a physics-based reservoir upscaling. At the end, it will help us in making appropriate field management decisions with reduced uncertainty.

This presentation will review joint inversion algorithms and workflows for integrating EM, seismic, and production data. It will analyze challenges, advantages, and disadvantages of these approaches. In particular, for reservoir characterization applications, joint structural and petrophysical algorithms for integrating EM and seismic data (CSEM and surface seismic, and crosswell EM and crosswell seismic) will be presented. For reservoir monitoring applications, the talk will describe EM data (for single-well, crosswell and STB) inversion algorithms constrained by the fluid-flow simulator. In the inversion for both EM and seismic, a full nonlinear approach (the so-called full-waveform inversion) will be employed so that all the information in the data can be utilized. Some test cases will be discussed.
