Humanity faces a crucial problem caused by anthropogenic carbon emissions driven by energy production, transportation, large-scale agriculture, and industrial production (steel and cement in particular). Carbon capture and sequestration (CCS) is one of the main tools at our disposal to address the problem. To significantly impact future climate change, CCS must scale well beyond current levels and soon reach the Gigatonnes level.

This workshop will focus on the subsurface challenges of large-scale geological sequestration and how geophysical methods can provide solutions to these challenges.

The workshop aims to advance the state-of-the-art geophysical technologies and their applications in identifying geological storage sites and monitoring safe long-term subsurface storage without creating new environmental and geological hazards.

The workshop format is hybrid. We plan to have about 50 attendees on-site at Stanford University and many more connected worldwide that will be fully engaged in the proceedings through modern telepresence technology.

The last morning of the workshop (Thursday, 30 June 2022) will be dedicated to a broad discussion of the “hot topics” for CCS-related research involving all participants (on-site and remote). The summary of this discussion will be shared with the applied geophysics community and will form the basis for broader discussions in the years to come.

Field Trip

In person registrations are sold out. Virtual registration only is now available. Please contact Teresa Dallis [email protected] with any registration questions.

Participants in this field trip will visit the Lawrence Livermore National Laboratory (LLNL). Two distinct program areas will be covered, the GEOSX multiphysics simulator and the Fiber Laser Group. For more than 60 years, the Lawrence Livermore National Laboratory has applied science and technology to make the world a safer place.


This workshop will introduce participants to GEOSX, an open-source reservoir simulator developed by Lawrence Livermore National Laboratory, Stanford University, TotalEnergies, and other contributors. The software focuses on solving challenging problems in geologic carbon sequestration, modeling tight coupling between multiphase flow, geomechanical, and thermal processes.  It runs portably on a variety of computing systems, from laptops to the world’s largest supercomputers.  This workshop will begin with an overview of the code, its design principles, and its current capabilities.  Interactive demos will then walk participants through using the code to solve relevant application problems.  The workshop will end by describing planned features on the development roadmap.  Significant time will be devoted to questions and discussion, so that users can describe their applications needs and learn how the project could support future activities.

Fiber Laser Group

Over the past decade, distributed fiber-based sensors have become a powerful new tool for the energy sector, with important successes in monitoring the production and integrity of oil and gas wells. In the coming decade, refined versions of these sensors may provide new understandings of geothermal wells, monitor the health of buried powerlines, and monitor the integrity of new carbon sequestration sites. LLNL’s Fiber Laser Group was established twenty years ago to further the Department of Energy’s interests in topics ranging from arrays of fiber-based lasers to drive future particle accelerators, to custom optical fibers and photonic instruments for subsurface explorations. This Fiber Fabrication Workshop will include a tour of LLNL’s fiber fabrication facilities, with explanations of techniques for fabricating custom optical fibers via stack-and-draw methods, including polarization-maintaining and hollow optical fibers.

Fees: US$100
*Please note if the registrant does not meet the facility security standards a full refund will be issued for the field trip.
