Title: Wettability: Establishing a NMR Wettability Index for Unconventional Rocks
Abstract:
Standardized and benchmarked wettability characterization and quantification workflows are lacking in unconventional reservoir development. Quantification of in situ wettability and of changes due to wettability alteration efforts can assist with completions, decisions and economic oil production. This webinar summarizes the establishment and validation of an NMR wettability index (NWI) for unconventional rocks. The method builds upon Looyestijn’s NMR wettability analysis methods for conventional rocks and has been tested on core plug samples from a variety of major producing unconventional reservoirs. It will be of interest to readers to note the marked range of wettability values quantified among the aforementioned tight formations. Our NWI model is well suited for data sets featuring complex oil and water T2 spectra with multiple peaks, common features of unconventional rock spectra. The results were subjected to comprehensive experimental and analytical validation, including complementary 3D NMR imaging and replication of the experiments with D2O. The validation procedure and advantages of the approach over other NMR wettability models are discussed in this review. Finally, best practices are detailed so that the SCAL methodology can be deployed on a larger scale.
Presenter: 
Michael Dick, Ph.D., Senior Research Scientist, Green Imaging
Presenter Bio: Mike has a Bachelor of Science degree from the University of New Brunswick. His post-graduate work focused primarily on molecular physics and included both a Masters degree from the University of New Brunswick and a Ph.D. from the University of Waterloo.
After graduation, Mike’s career diversified working first in astrophysics while doing a post-doctoral fellowship at NASA’s Jet Propulsion Lab. Following this position, Mike moved into the field of nuclear physics in Chalk River Ontario with Bubble Technology Industries (BTI) as a research scientist. His work with BTI focused primarily on developing unique radiation detectors for defence and homeland security organizations, first responders, space agencies, regulatory/standards groups, and research institutions. This work has resulted in three patent filings.
Mike joined Green Imaging Technologies in September 2015 as a Principal Research Scientist. Mike works closely with our research team innovating new NMR techniques and tools for our clients.
