Bio
Ali Tura is Professor of Geophysics and Director of Reservoir Characterization Project at Colorado School of Mines. His expertise is in the areas of seismic data processing, seismic analysis, time-lapse seismic, rock physics, fiber optic technology and data analytics. He is also Chief Scientist at Tulip Geosciences, a geosciences consulting and training company. Prior to this he was Geophysical Senior Fellow at ConocoPhillips. Ali was a founding member and COO of 4th Wave Imaging, a seismic R&D company. His other responsibilities have been leading time-lapse seismic reservoir monitoring at Chevron and Shell, and amplitude-preserving migration based AVO analysis at Elf (now Total).

Ali received a B.Sc. degree from Istanbul University, and an M.S. and Ph.D. degree from the University of California, Berkeley, all in Engineering Geosciences. His work during this period ranged from deconvolution of seismic data, to full-waveform seismic modeling of vertical seismic profiling (VSP) data, to fracture detection from cross-well reflection/diffraction tomography in anisotropic media at Lawrence Berkeley National Laboratory. He has taught graduate level courses at the University of Texas, Dallas, Mathematical Sciences Department, and Istanbul Technical University, Geophysics Department. He was a visiting scientist at Karlsruhe University, Germany, where he worked on comparing theoretical aspects of Kirchhoff versus Born modeling and migration. Ali has mentored many Ph.D. interns at ConocoPhillips and Chevron and lead an industrial consortium on time-lapse seismic while at 4th Wave Imaging.

Ali is active within the SEG. He served as SEG Vice-president, Vice-chairman and Chairman of the SEG Global Affairs Committee, and Chairman of the SEG Research Committee. He has been a member and Chairman of the editorial board of The Leading Edge and Associate Editor of Geophysics. He has also been a board member of SEG Global Inc. and Co-chairman of OTC Technical Committee.

Associate Professor
RCP Co-Director

Bio

Dr. Ge Jin is Assistant Professor of Geophysics and Co-director of the Reservoir Characterization Project. He is interested in Fiber-Optic Sensing (FOS) and machine-learning applications in the oil industry, as well as seismic imaging and interpretation. He obtained his Ph.D. in Geophysics from Columbia University and dual B.S. in Geophysics and Computer Science from Peking University. 

From 2014-2019, Dr. Jin worked at ConocoPhillips as a research geophysicist. There he was involved in many cross-functional research projects and made a major breakthrough by discovering the rich information hidden in the extra-low frequency band of the DAS signal. He also developed a series of algorithms that utilize FOS data for production logging, hydraulic fracture detection, well production interference evaluation, and microseismic monitoring. In addition to FOS research, he has developed several workflows that use ground roll energy to image near-surface structures, which have been applied on land seismic data from multiple fields. He has worked on several 4D seismic processing and interpretation projects, including time-shift estimation improvement, rock-physics modeling, and machine-learning-based 4-D interpretation.
