Youssef Marzouk, Associate Professor in MIT’s Department of Aeronautics and Astronautics, presents “Computational challenges in Bayesian inversion” at the MIT Earth Resources Laboratory. “Bayesian inference provides a natural framework for quantifying uncertainty in parameter estimates and model predictions, and for combining heterogeneous sources of information. Characterizing the results of Bayesian inference—by simulating from the posterior…

Dr. Julius Kusuma, Principal Scientist and Program Manager at Schlumberger-Doll Research, presents “Model-Based Telemetry: Digital Communication Inspired by Geophysics” at the MIT Earth Resources Laboratory. “Telemetry is critical for oilfield operations, both in the sub-surface and in the subsea. It enables real-time interpretation and decision-making in many areas of oilfield, such as drilling, logging, well-testing,…

Each year ERL invites representatives of our Founding Member companies to MIT for a day and a half of talks, mostly by our graduate students and psotdocs, about our latest research, as well as some fun networking opportunities.  This year’s meeting will take place May 23-25 and the theme will be: Simulation, Inference, and Machine…

Dr. Florent Benguier, Professor at U. Grenoble Alpes, presents “Virtual seismic source monitoring of Earthquakes” at the MIT Earth Resources Laboratory. “The early work of Aki 1957 paved the way to the use of erratic, seismic noise as an ubiquitous source of useful signal for imaging the Earth. More recently, in the last 15 years,…

Dr. Wenlian Xiao, Professor at Southwestern Petroleum University and Visiting Scientist at MIT, presents “Nonlinear Effective Pressure Law in Tight Rocks.” “The concept of effective pressure Peff was firstly introduced by Terzaghi[1925], and it’s commonly used in the problems where porous rock and pore pressure Pf are involved. Terzaghi’ effective pressure is defined by Peff…

Dr. Elisabetta Sassaroli, medical physicist and Research Scientist at Brigham and Women’s Hospital, presents “Focusing Ultrasound through the Skull by an Indirect Wavefront Sensing Approach.” “Focusing ultrasound through the skull is a challenging problem. As the ultrasound propagates through the skull, it encounters at first a large impedance mismatch at the skull-water interface, and then…

For IAP and Spring 2018 ERL-afiliated instructors will be offering two new subjects for graduate students through the Mathematics department with applications to geophysics and a variety of other fields.  During IAP, Dr. Aimé Fournier of ERL/EAPS and Dr. Phillippe Ricoux of of our partner company Total SA will offer “18.S998: How to Build Numerical…

Dr. Ángel Rodríguez Rozas, Researcher at BCAM – Basque Center for Applied Mathematics, presents “Fast Simulation and Inversion of Borehole Resistivity Measurements.” “Accurate inversion methods are needed to provide a precise quantitative estimation of the subsurface’s resistivity distribution, enabling the identification and assessment of hydrocarbon-bearing formations. In this seminar, I will focus on the fast…

Greg McLaskey, Assistant Professor at Cornell U., presents “Laboratory generated earthquakes from meter-scale to mm-scale with heterogeneous fault properties.” “Laboratory generated earthquakes and acoustic emissions range from M -2, for meter-scale ruptures, down to M -10. On the larger scale, I describe dynamic rupture events that terminate within a 3 m long granite sample due…
