CO2 injection, coupled process testing, and subsurface imaging/sensing are three studies among the first suite of experiments selected for design and implementation at the USA's Deep Underground Science and Engineering Laboratory (DUSEL).The studies, initiated in 2009, include workshops to develop international collaborations. The USA-France collaborations have been established between the Laboratoire Souterrain à Bas Bruit (LSBB) and the Earth Sciences Division of Lawrence Berkeley National Laboratory (LBNL) through the following activities:

  1. Exchanges for the project on High-Pulse Poroelasticity Protocol (HPPP), with annual and biannual meetings and visits on designing the sensors installed in boreholes, modeling the field test configurations, and interpreting test results.

  2. Expansions of research topic discussions initiated at the 2007 2nd inter-Disciplinary Underground Science and Technology (i-DUST) conference.

  3. Organization jointly an American Geophysical Union session NH31C on seismic coupling and correlation from underground, surface, to the ionosphere.

Some exciting findings that emerge from such collaborative national subsurface laboratories researches include first field measurement of coupled seismic–electromagnetic–poroelastic waves in saturated and unsaturated zones, underground field measurements of magnetic profiles correlated with findings by radar soundings, sightings, and satellite observations of ionospheric electrical depressions above seismic regions. Fruitful discussions were also initiated on testing beyond CO2 supercritical-gas phase transitions to include geochemical interactions with cement and geomicrobiological sampling along fluid columns planned at DUSEL, aswell as in carbonate rocks at LSBB. These LBNL–LSBB collaborations are examples that can lead to initiatives in developing international, interdisciplinary innovations. We plan to jointly organize a workshop in the 2012 Beijing ISRM Congress and other meetings worldwide to explore i-DUST collaborations and beyond.


The Deep Underground Science and Engineering Laboratory (DUSEL) is a reopened underground facility at the former Home stake mine, Lead, South Dakota, USA.
