The next meeting of the Boston SPWLA will be helf on Friday, November 6, 11:00 AM, in the Auditorium of the Schlumberger-Doll Research center in Cambridge, MA. We will hear from Manika Prasad, professor of Petroleum Engineering at Colorado School of Mines, followed by a networking lunch sponsored by Schlumberger (see below for details). To RSVP for the meeting, please send a message to by October 30. In addition, Manika will have time for individual meetings. If you are interested in speaking with her one-on-one, please mention in your RSVP. Driving directions can be found here: It is suggested that you arrive 10 minutes prior to the scheduled meeting. Street parking is hard to come by. There are several parking garages nearby (expect to pay at least $14 for 2 hours). You can also walk to SDR from the Kendall Square T Station.


Surface Controls onStorage, Stiffness, and Transport Properties of Rocks

By Prof. Manika Prasad, Petroleum Engineering, Colorado School of Mines

Shales are characterized by large surface areas. In such heterogeneous systems, mineralogy, surface area, and surface chemistry play a large role in preferential fluid coverage. By understanding these interactions, we can devise indirect geophysical experiments to determine them. In organic-rich rocks, fluids compete to cover the surfaces of the inorganic and the organic constituents. A combination of preferential fluid coverage of polar and non-polar fluids with acoustic and electrical measurements allows us to build realistic rock models. In organic-rich rocks, a further complication is provided by maturity effects on surface area and porosity evolution. These changes, in turn, affect velocity and conductivity of organic-rich rocks. I will discuss the effects of fluid polarity and rock mineralogy on pore size distribution measurements and how to use this information in existing models.






Officer Biographies

President: Andrew E. Pomerantz is the Geochemistry Program Manager at Schlumberger-Doll Research.  His research focuses on the development of novel techniques to characterize the chemical composition of kerogen and asphaltenes, including methods in mass spectrometry, X-ray spectroscopy, and infrared spectroscopy.  That molecular information is used to understand fundamental physical and chemical processes in petroleum such as asphaltene compositional grading and storage and transport in shales.   He graduated from Stanford University with a PhD in chemistry in 2005 and has co-authored 50 peer-reviewed publications.

Vice President: Ravinath Kausik K.V. is a Senior Research scientist at Schlumberger-Doll Research. At Schlumberger he has focused on the development of novel NMR and petrophysical techniques for porous media, especially unconventional gas and tight oil organic shale plays. He has developed new NMR pulse sequences and petrophysical workflows for better understanding various fractions of unconventional plays such as the stored gas, bitumen, producible oil, kerogen and bound water. He is also involved in the development of the next generation NMR relaxometry and diffusometry measurements for both laboratory and logging applications. He obtained a M.Sc. from IIT Madras, India and Ph.D. degree in physics from the University of Ulm, Germany.  He worked as a postdoctoral fellow at the University of California, Santa Barbara before joining Schlumberger-Doll Research in 2009.

Secretary: Julie E. Kowan is a Geomechanics Advisor at Baker Hughes. She has been working in the field of geomechanics since early 2005. Julie has expertise in the areas of in-situ stress determination, wellbore stability, unconventional resources, pore pressure prediction, fracture permeability analysis, compaction and sand production prediction. Her primary responsibility is to lead geomechanics consulting projects and use geomechanical modeling to help operators plan their drilling programs and field development. In addition to leading consulting projects, she assists sales efforts, teaches technical training courses and presents at technical conferences. Julie received her B.S. degree in Geology from Rutgers University in 2001 and her M.Sc. in Geology from Brown University in 2003.

Treasurer: Tancredi Botto is a Principal Research scientist at Schlumberger-Doll Research, where he has contributed to and initiated a number of research projects based on nuclear technologies. Among those, he has developed and field tested a novel deep-reading density imager based on naturally occurring cosmic rays. He is also involved in nuclear modeling and microwave sensor research. Tancredi holds a PhD from the Vrije Universiteit, Amsterdam (1999) and a M.Sc. from the University of Genoa, Italy. Prior to joining Schlumberger in 2005 he worked on experimental nuclear physics as a Research Scientist at the MIT Laboratory for Nuclear Science.
