Abstract A special session was held at the 2014 Society of Exploration Geophysicists (SEG) Annual Meeting in Denver to brainstorm on the topic of what microseismic data can say about fluid flow. The special session was sponsored by the Research Committee of SEG and coorganized by Oleg Poliannikov (Massachusetts Institute of Technology) and Hugues Djikpesse (Schlumberger, now CHRYSOS Technologies L.L.C). It consisted of eight presentations with a broad range of speakers from academia and industry and was attended by about 150 participants. The findings of this special session are reported, and then possible directions for the future of flow-guided microseismic research are discussed.
