Announced during this month’s Banquet and Awards, held in Las Vegas, Nevada by R&D Magazine, EESA’s Tom Daley, Jonathan Ajo-Franklin, and Ernie Majer have won a 2015 R&D 100 award, for the Continuous Active-Source Seismic Monitoring (CASSM).
CASSM is a combination of experimental methodology, geometry, and instrumentation enabling virtually continuous monitoring of subsurface seismic properties within a defined area (hundreds of m2). Application utilizing crosswell geometry has allowed CASSM to achieve a measurement precision far beyond previous field-scale experiments. Unlike the “snapshots” provided by present time-lapse imaging methods, CASSM’s continuous monitoring produces real-time information, capturing fast processes and short events often missed by present methods. Also, because CASSM can be operated while fluid is being injected into/withdrawn from a well, it eliminates the substantial labor costs and inefficiencies resulting from switching wells between borehole monitoring and production. Initial development work for CASSM was initially funded by U.S. Department of Energy’s (DOE) carbon storage program and other funding from DOE fossil energy and SERDP/ESTCP programs.
CASSM is a sixth R&D 100 winner for EESA, in the past nine years. CASSM joins the Carbon Explorer (Jim Bishop, 2006), the Berkeley Unexploded Ordnance Discriminator (Erika Gasperikova, 2007), the Berkeley Lab PhyloChip (Gary Andersen, 2008), and the EM Geo Electromagnetic Geological Mapper (Greg Newman, 2009), and the Berkeley Lab Multiplex Chemotyping Microarray (Hoi-Ying Holman, 2014)—as a winner of this award.
