Today Science News featured Kiran’s constraints on convective dissolution rates in their news section under the headline “Storing greenhouse gases — for a million years“, this article also made it into the news letter of the Geochemical Society. Science writer Jia You apparently decided that senior GPMG affiliate Martin Cassidy was the most photogenic team member. A good summary of Kiran’s work is also featured on Ars Technica under the title Natural underground CO2 reservoir reveals clues about storage.

07/11/2014: DOE Energy Frontiers Research Center is renewed

The Center for Subsurface Energy Security a DOE Energy Frontiers Research Center lead by the Center for Petroleum and Geosystems Engineering (PGE) has been been renewed for 4 additional years. The center aims to improve geologic CO2 storage, which is a key technology for mitigating greenhouse gas emissions from fossil fuel consumption — especially from coal and natural gas used to generate electricity. Our GPMG team will continue to address the long-term fate of CO2 in geological formations through the study of geological analogs.

04/30/2012: Soheil Ghanbarzadeh wins Statoil doctoral fellowship:

Soheil won the Statoil graduate fellowship to study the pore network in rock salt. Due to the high solubility the shape of the pores is close to textural equilibrium, and therefore a minimal surface. The topology of the network is determined by the surface tension between different salt grains and between the salt and the brine.  As the surface energies change with temperature and pressure, the porenetwork may become connected and salt, which is usually considered impermeable, can become a major fluid pathway.

12/8/10: GRL editor’s highlight:
Characterizing channels for transport of melt in mantle

To investigate how dunite channels would form and how melt would flow through them in an upwelling mantle, Liang et al. (2010) conducted numerical simulations. They found that interconnected dunite channels form the shallow part of the porous channels through which melt passes; deeper in the mantle, melt travels through channels composed of the rocks harzburgite and lherzolite. These results could help geologists interpret field measurements and improve models for mantle melt migration, shedding light on mantle dynamics and crust formation.
