FREQUENCY AND TEMPERATURE DEPENDENCE OF 2D NMR T1-T2 MAPS OF SHALE
presented by
Dr. Ravinath Kausik K.V, Senior Research scientist of AI and Machine learning at Schlumberger-Doll Research in Cambridge, USA

Abstract:

 Two-dimensional nuclear magnetic resonance (NMR) T1-T2 maps are fast becoming a routine methodology for fluid typing in unconventional shale rocks due to their sensitivity to molecular mobility. The differences in the mobility of the different components of unconventional plays—ranging from solid kerogen to the fluid components of viscous bitumen, clay-associated water, oil in oil-wet organic pores to fluids (oil and water) in the mixed-wet inorganic pores and natural fractures—is measured by this methodology to determine the fluid types and their confining environments for the construction of universal 2D maps of different wells. One of the biggest challenges for the universal application of this methodology is the need for an understanding of the impact of the variation in frequency on the applications of different wireline, LWD, wellsite and laboratory tools which work at different Larmor frequencies, and of the variation in temperature between different basins, wells, or even multiple depths within a well. In this talk we describe the relationship of changes in molecular mobility of the different fluids in shale rocks to variations in temperature and their influence on 2D NMR T1-T2 maps measured at different frequencies.

Speaker Biography:

Dr. Ravinath Kausik K.V is a Senior Research scientist of AI and Machine learning at Schlumberger-Doll Research in Cambridge, USA where he has focused on the development of novel NMR and petrophysical techniques, especially of unconventional shale gas and tight oil formations. His work has led to the development of recently commercialized techniques such as TGIP-NMR and RPI for unconventional shale gas and tight oil plays, respectively. He has also worked on the development of next generation NMR diffusion and relaxation measurements for both laboratory and downhole applications. His work has been recognized with the Conrad Schlumberger prize for technical depth and the Henry-Doll prize for innovation within Schlumberger, and serves as the distinguished speaker for SPWLA from 2015-16 2016-17 and 2018-19. He was elected to the international advisory committee of the Magnetic Resonance in Porous Media (MRPM). He obtained a M.Sc. from IIT Madras, India and Ph.D. degree in physics from the Universität Ulm, Germany. He worked as a postdoctoral fellow at the University of California, Santa Barbara before joining Schlumberger-Doll Research in 2009. He has co-authored more than 30 peer-reviewed publications and several patent applications and is a scientific reviewer for more than 10 international journals.
